assignments for + networking and system administration courses. + + Each assignment is represented by a task which a student should perform. + Tasks are customised for each student by setting a number of parameters + for each task. + + Typically, each task involves a number of interconnected computers, one + of which contains the kpov_judge testing program (test_task.py). After + solving the task, a student runs the test_task.py to check their solution. + The testing results are uploaded to a server for grading and feedback can + be provided immediately. + +Using kpov_judge as a student + + For each task, the student is supposed to set up some services or resources + on one or multiple computers. The services or resources are then checked to + see if the task has been performed successfully. The result of the test is + reported back to the student. + + The instructions for each task are included in the task itself. The + parameters for each task are either prepared for each student in advance or + generated the moment a student tries to check whether they have performed + the task successfully. + + The computers for each task are typically set up by downloading a set of + virtual disk images, creating a number of virtual machines using these + disks and connecting these virtual machines using virtual or physical + networks. After the computers are set up, a student can set up the services + required by the instructions. + + The checking is done by the program test_task.py. This program can run in + both an on-line mode where some of the testing is done by a remote server + or an off-line mode where all the testing is done locally. Since kpov_judge + is expected to be mostly used by schools, usually the on-line mode will be + used by students for handing in graded assignments and for immediate + feedback during practice. + +Using kpov_judge as a teacher + + TBD + +Preparing tasks + + Within the kpov_judge repository, tasks are stored under kpov_judge/tasks. + New tasks should be added as sub-directories of tasks. + + Each task is defined by a python file named task.py . The file task.py + contains: + - instructions - the task instructions in multiple languages, + - computers - a dictionary describing the computers used for this task, + - networks - a dictionary describing the network links for this task, + - params_meta - a dictionary with a description and other metadata for + each parameter for this task + - task(...) - a function for testing the student's solution of this task. + All the arguments for this function should be described in + params_meta and should be public. This function is run by + the student to test their task solution. The output of + task(...) should be relatively hard to fake - for example, + if the student had to set up the default route on one of + the computers, this function could return a string + containing the output of the 'netstat -r' command. The + idea is to make it harder for the student to fake the + correct output of task(...) than it would be to just + solve the task. + - task_check(results, params) - check the output of task(...). + The parameter results contains the return value of task(...). + The parameter params contains a dictionary of values for each + parameter used for this task + This function is used for grading the task and should return + a value between 0 and 10 with 0 representing the lowest and 10 + representing the highest number of points attainable for solving + the task. + - gen_params(user_id, params_meta) - prepare all the parameters for + this task. For most tasks, most of the parameters will be randomly + generated according to the metadata in params_meta. A number of + helper functions for generating the parameters are available in + kpov_util.py + - prepare_disks(templates, params) - prepare the disk images for this + task. For some tasks it might be neccessarry to create or edit + some files on the virtual disk images used by each student to set + up the computers needed for this task. The parameter templates + contains a dictionary of guestfs objects. Refer to the libguestfs + documentation for more information. + + Typically, a new task is created by the following steps: + - prepare a (virtual) testing computer + - checkout the kpov_judge repository on the testing computer + - create a copy of an existing task to use as reference + - change the instructions in task.py + - create the other computers and networks involved in this task + - change the dictionaries computers and networks in task.py + - change the params_meta to correspond to the new instructions. + - write a task(...) function which returns a simple string + - write a task_check function which simply prints out the parameter + results + - write a gen_params(user_id, params_meta) function + - run test_task -g to test gen_params and set the initial task parameters + - debug everything you have created so far by performing the task + and running test_task.py as many times as needed + - write the task_check and gen_params functions + - write the prepare_disks function + - commit the new task to the repository + - checkout the task on the web-based evaluation system + - upload the clean virtual disk images, add the task to the web-based + system + - log in as a student, download the images, solve task, run task_check + - debug the task if needed + + For each course taught using kpov_judge, a directory should be created + under kpov_judge/courses. Each course's directory can be arranged in any + way the lecturer sees fit. For fri_kpov, the directory contains one + sub-directory for each lesson. Each lesson consists of a task the student + should perform before attending class (preparation), the instructions + for that week's class (lecture) and a task the student will be graded on + after the class (evaluation). + + + + diff --git a/add_task.py b/add_task.py new file mode 100755 index 0000000..7bb2f3e --- /dev/null +++ b/add_task.py @@ -0,0 +1,124 @@ +#!/usr/bin/env python3 + +import glob +import inspect +import os +import settings +import sys +import urllib + +import kpov_util +import pymongo +from bson import Binary + +def task_check(results, params): + data = { + 'results': json.dumps(results), + 'params': json.dumps({k: v for k, v in params.items() if k != 'token'}), + } + #

After - solving the task, a student runs the test_task.py to check their solution. - The testing results are uploaded to a server for grading and feedback can - be provided immediately. - -Using kpov_judge as a student - - For each task, the student is supposed to set up some services or resources - on one or multiple computers. The services or resources are then checked to - see if the task has been performed successfully. The result of the test is - reported back to the student. - - The instructions for each task are included in the task itself. The - parameters for each task are either prepared for each student in advance or - generated the moment a student tries to check whether they have performed - the task successfully. - - The computers for each task are typically set up by downloading a set of - virtual disk images, creating a number of virtual machines using these - disks and connecting these virtual machines using virtual or physical - networks. After the computers are set up, a student can set up the services - required by the instructions. - - The checking is done by the program test_task.py. This program can run in - both an on-line mode where some of the testing is done by a remote server - or an off-line mode where all the testing is done locally. Since kpov_judge - is expected to be mostly used by schools, usually the on-line mode will be - used by students for handing in graded assignments and for immediate - feedback during practice. - -Using kpov_judge as a teacher - - TBD - -Preparing tasks - - Within the kpov_judge repository, tasks are stored under kpov_judge/tasks. - New tasks should be added as sub-directories of tasks. - - Each task is defined by a python file named task.py . The file task.py - contains: - - instructions - the task instructions in multiple languages, - - computers - a dictionary describing the computers used for this task, - - networks - a dictionary describing the network links for this task, - - params_meta - a dictionary with a description and other metadata for - each parameter for this task - - task(...) - a function for testing the student's solution of this task. - All the arguments for this function should be described in - params_meta and should be public. This function is run by - the student to test their task solution. The output of - task(...) should be relatively hard to fake - for example, - if the student had to set up the default route on one of - the computers, this function could return a string - containing the output of the 'netstat -r' command. The - idea is to make it harder for the student to fake the - correct output of task(...) than it would be to just - solve the task. - - task_check(results, params) - check the output of task(...). - The parameter results contains the return value of task(...). - The parameter params contains a dictionary of values for each - parameter used for this task - This function is used for grading the task and should return - a value between 0 and 10 with 0 representing the lowest and 10 - representing the highest number of points attainable for solving - the task. - - gen_params(user_id, params_meta) - prepare all the parameters for - this task. For most tasks, most of the parameters will be randomly - generated according to the metadata in params_meta. A number of - helper functions for generating the parameters are available in - kpov_util.py - - prepare_disks(templates, params) - prepare the disk images for this - task. For some tasks it might be neccessarry to create or edit - some files on the virtual disk images used by each student to set - up the computers needed for this task. The parameter templates - contains a dictionary of guestfs objects. Refer to the libguestfs - documentation for more information. - - Typically, a new task is created by the following steps: - - prepare a (virtual) testing computer - - checkout the kpov_judge repository on the testing computer - - create a copy of an existing task to use as reference - - change the instructions in task.py - - create the other computers and networks involved in this task - - change the dictionaries computers and networks in task.py - - change the params_meta to correspond to the new instructions. - - write a task(...) function which returns a simple string - - write a task_check function which simply prints out the parameter - results - - write a gen_params(user_id, params_meta) function - - run test_task -g to test gen_params and set the initial task parameters - - debug everything you have created so far by performing the task - and running test_task.py as many times as needed - - write the task_check and gen_params functions - - write the prepare_disks function - - commit the new task to the repository - - checkout the task on the web-based evaluation system - - upload the clean virtual disk images, add the task to the web-based - system - - log in as a student, download the images, solve task, run task_check - - debug the task if needed - - For each course taught using kpov_judge, a directory should be created - under kpov_judge/courses. Each course's directory can be arranged in any - way the lecturer sees fit. For fri_kpov, the directory contains one - sub-directory for each lesson. Each lesson consists of a task the student - should perform before attending class (preparation), the instructions - for that week's class (lecture) and a task the student will be graded on - after the class (evaluation). -

Purpose of this exercise

-

To learn how to use a few BASH commands.

-

Quick summary

-

You will use bash commands like: mv, grep, env etc.

-

Instructions

- -

    -
  1. Log into your system and in your home folder you will find a directory called Mapa containing 20 files.
    2. -
  2. Rename all files, by replacing all minus signs with underscores using the command: "rename 's/-/_/' *".
    3. -
  3. Remove all files from /home/user/mapa/mojimenik into /home/user/novi using command: "mkdir-p /home/user/novi && mv /home/user/mapa/mojimenik/* /home/user/novi"
    4. -
  4. Write all regular files containing a string "mama" into file "mama.txt", and all errors in file "napake.txt" by using: "find . -type f | grep mama 1> mama.txt 2> napake.txt".
    5. -
  5. Inspect /var/log/syslog for 5 seconds and in case a string"zmeda" appears in syslog, write "imam ga". Also while inspecting syslog, reduce the counter by every second using a command: "for i in 5 4 3 2 1; do echo $i; echo $(sed -n "$i p" /var/log/syslog | grep zmeda > /dev/null && echo "imam ga"); sleep 1; done".
    6. -
  6. Set a variable TEST to the same value as the variable USER + the number of environmen variables not containing string "TEST" in their names, by adding ~/.bashrc to the end of the file: "export TEST=$USER" + "$(env | grep -v TEST | wc -l)"
    7. -

Namen vaje

-

Naučite se uporabe nekaj BASH ukazov.

-

Naloga na hitro

-

Uporabljali boste BASH ukaze kot so: mv, grep, env in druge.

-

Navodila

- -

    -
  1. Prijavite se v sistem. V domačem imeniku najdete imenik Mapa z 20 datotekami.
    2. -
  2. Preimenujete vse datoteke tako, da zamenjate minuse s podčrtaji z ukazom: "rename 's/-/_/' *".
    3. -
  3. Premaknite vse datoteke /home/user/mapa/mojimenik v /home/user/novi z ukazom: "mkdir-p /home/user/novi && mv /home/user/mapa/mojimenik/* /home/user/novi"
    4. -
  4. V datoteko "mama.txt" zapišite vse navadne datoteke v trenutnem imeniku, ki vsebujejo niz "mama", v datoteko "napake.txt" pa zapišite vse morebitne napake z ukazom: "find . -type f | grep mama 1> mama.txt 2> napake.txt".
    5. -
  5. Sledite vsebini /var/log/syslog za 5 sekund in v primeru, da se v syslogu pojavi niz "zmeda", izpišite "imam ga". Poleg tega med sledenjem syslog-u odštevajte od 5 do 1 z ukazom: "for i in 5 4 3 2 1; do echo $i; echo $(sed -n "$i p" /var/log/syslog | grep zmeda > /dev/null && echo "imam ga"); sleep 1; done".
    6. -
  6. Nastavite okoljsko spremenljivko TEST, da bo imela isto vrednost kot okoljska spremenljivka USER + število okoljskih spremenljivk, ki v imenu ali vrednosti ne vsebujejo besede TEST tako, da na koncu datoteke ~/.bashrc dodate: "export TEST=$USER" + "$(env | grep -v TEST | wc -l)"

To pomeni, da boste verjetno morali po vsakem testiranju datoteke premakniti nazaj. Za krajšanje ukaza lahko izkoristite imeni imenikov. - -

-Napiši ukaz, ki s pomočjo ukaza grep v datoteko ~/mama.txt izpiše imena vseh navadnih (ne skritih) datotek v trenutnem imeniku, ki vsebujejo niz mama, v datoteko ~/napake.txt pa izpiše vse morebitne napake (npr. to, da so nekateri objekti v trenutnem imeniku dejansko imeniki ali napačne simbolične povezave).

Before running test_task.py, make sure {{mv_src_dir}} contains the same files as when you downloaded your virtual disk. This probably means that you will have to move the files back from {{mv_dst_dir}} to {{mv_src_dir}} after each test. - -

-Come up with a command or sequence of commands in bash which will, using grep, write the names all normal (not hidden) files which contain the string mama and are located in the working directory (pwd) into the file ~/mama.txt while writing errors such as files in current directory being folders or symbolic links in the file called napake.txt.

Custom rdate

-

Short preview:

- Set time on server using rdate. Write a program that converts 32-bit numbers into a readable time format.

-

Instructions:

- 1. Downlaod Student.vdi (client) and SimpleArbiter.vdi (server) from the virtual machine images folder
- 2. Use VirtualBox (or similar) to create two virtual machines, select the virtual disk images from the previous step as hard drives
- 3. Run both virtual machines.
- 4. Login on client user: root pass: kaboom and server user: tester pass: tester

- - -

First part: update time using rdate.

-

- 1. Find and remember your server IP address. (ifconfig)


- 2. Install rdate with sudo apt-get install rdate
- 3. On Student client use rdate to update the machine time rdate SERVER_IP

- Note: It's NOT an error if the updated time does not match the correct time.
-

-

Second part: write a program that converts 32bit numbers into a readable time format.

-

- You can write a program in Java or Python using your favourite text editor. -

-

Java

-

- 1. We use nano guliver.java to create a new blank file
- 2. Write a program that converts 32bit numbers into a readable time format.
-

- 3. Press Ctrl+X, then Y and Enter to save the program
- 4. In case you don't have java installed use sudo apt-get install openjdk-6-jdk
-
- 5. To compile use javac bintodec3.java
- 6. Run the created program with java guliver and input the server IP or name...
-
-

-

Python

- 1. Use nano guliver.py to create a new empty python file.
- 2. Write a program that converts 32bit numbers into a readable time format.
-
- 3. Press Ctrl+X, then Y and Enter to save our program
- 4. Run the created program with python guliver.py

-

-

Testing

-

- 1. Use command ./run_test.py to run the tester
-
- 2. Your username and password are the same as on ucilnica (npr.: "pz1234@student.uni-lj.si" in "geslo123").
-
- 3. Name of the task should look like 09.predvaja.
- 4. When prompted for file path insert your program path (example: if bintodec3.py is in the same folder as program run_test.py run with ./bintodec3.py).
- 5. Then input your server IP address (SimpleArbiterRDate).
- 6. If all goes well the program should give you an OK that means you've completed your task successfully. -

-

- 1. Z imenika s slikami virtualnih računalnikov povlecite sliki Student.vdi(klient) in SimpleArbiterRDate.vdi(strežnik).
- 2. Z VirtualBoxom (ali podobnim) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte Student.vdi ter SimpleArbiterRDate.vdi.
- 3. Zaženite oba navidezna računalnika.
- 4. Na Student se prijavite z uporabnikom root in geslom kaboom - na SimpleArbiterRDate pa z uporabnikom tester in geslom tester. -

- -

Prvi del naloge: posodobi uro računalnika s pomočjo rdate.

-

- 1. Preverite in si zapišite IP naslov na SimpleArbiterRDate. (ifconfig)


- 2. Z ukazom sudo apt-get install rdate namestimo program rdate.
- 3. Na Student z pomočjo rdate posodobi uro računalnika. rdate IP_SIMPLE_ARBITER

- Opozorilo: NI napaka, če se posodobljen čas ne ujema s pravilnim časom.
-

-

Drugi del naloge: napiši program, ki pretvori binarni zapis 32-bitnega števila v časovni format.

-

- Nalogo lahko rešite v Javi ali v Pythonu. Prav tako pa lahko kodo pišete v poljubnem tekstovnem urejevalniku.

-

-

Java

-

- 1. Z ukazom nano guliver.java ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
- 2. Napišemo program za pretvarjanje 32-bitnega števila v čas
- 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.
- 4. Če je še nimamo, naložimo Javo sudo apt-get install openjdk-6-jdk

- 5. Prevedemo program javac bintodec3.java
- 6. Lahko ga še zaženemo ter preizkusimo java guliver.Na standardni vhod vnasemo IP naslov ali ime strežnika NTP strežnikom, ki nam pošlje 32 bitno število in pretvori v čas

-

-

Python

-

- 1. Z ukazom nano guliver.py ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
- 2. Napišemo program za pretvarjanje 32-bitnega števila v čas
- 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.
- 4. Program zaženemo z ukazom python guliver.py

-

- -

Testiranje

-

- 1. Lahko poženemo tester; z ukazom ./run_test.py
-
- 2. Kot "Upor. Ime" in "Geslo" napišite vaše podatke učilnice. (npr.: "pz1234@student.uni-lj.si" in "geslo123")
-
- 3. Kot ime naloge vpišite 09.predvaja.
- 4. Ko vas program vpraša po poti programa vnesite vašo pot do programa za pretvarjanje. (npr.: če imate program bintodec3.py v isti mapi kot program run_test.py, vnesete: ./bintodec3.py)
- 5. Povpraša tudi po IP naslovu SimpleArbiterjaRDate, vnesite.
- 6. Če je šlo vse po sreči, program vrne OK vi pa ste opravili nalogo. -

Purpose of this exercise

-

How to perform live boot using a DHCP server.

- - -

We need VirtualBox and the following 4 virtual -machines: -

-

- -

Schematics of our subnet

- slika-01 -

Our goal is to make BootableClient A get it's IP -through DHCP server and boot up using file -A, which is located on simpleArbiterGW,
If we run -BootableClient B machines, we would like it to retrieve it's IP -through DHCP server and boot from some live ISO which is also located on -SimpleArbiterGW. -

- -

Setting up simpleArbiterGW

-

Download simpleArbiterGW.vdi -and then run VirtualBox. After the file is downloaded, choose the New -option in VirtualBoxu and set simpleArbiterGW in the Name -field.
Memory size, should be set accordingly (1gb will suffice). Then choose "Use an existing virtual hard drive file" and select simpleArbiterGW.vdi clicking Create.

-
- slika-02 -

We start our virtual machines simpleArbiterGW using the -following login -credentials; username: "root", password: "kaboom".

- At the start, the computer on NAt get's it's IP(in our case 10.0.2.15).
(to check this useifconfig) We now use this address and eth0 interface to access the internet.

- slika-03 -

However, we would like this machine to have 2 -interfaces! One on NAT(we already have this one), and the other one on Internal Network,
throuh which we will communicate wiht the DHCP Server and other machines on our Internal Network.

- We add a new interface, by turning off the virtual machine, -select our machine in VirtualBox and select -računalnik, ter v VirtualBoxu Settings -> Network
- Adapter 1 is already set to NAT, we set Adapter -2 to -Internal Network

- slika-04 -

So, now we have two network interfaces!
In VirtuaBox -we can define multiple Internal Networks, however, for our needs two -will suffice. We save the settings and restart simpleArbiterGW.

- What we must do now, is to assign both interfaces IP addresses. We do this by setting theinterfacesfile - located at/etc/network.

- slika-05 -

Eth0 was already handled by and integrated DHCP, so eth0 had been assigned an IP).
- We have to set up the other network interface. If we don't know it's name, we find it out using ifconfig -a.

- slika-06 -

We can conclude the interface names is set to Eth1. - Now we would like to assign an IP naslov to Eth1.
- Ifconfig could be used, but rebooting the machine would reset the settings. Which is not ideal :)
- So configuring /etc/network/interfaces would be a better idea.

- Let's make up a random local network or a local area network or local area network address and assign it to eth1. -

- slika-07 -

We save the config file. Our machine still has no IP on eth1 so we use the ifup eth1 command

- slika-08
-

Now we use the ifconfig command, to see whether and ip is assigned to eth1 interface

- slika-09 -

We can see the IP is set. Now let's set up the DHCP -Server!

- -

Setting up DHCP Server

-

We download simpleArbiterDhcp.vdi and start VirtualBox. After the file had been dowloaded we select New in VirtualBoxu and unde rthe Name tag write DHCP Server.
We set the Memory size accordingly(1gb of memory should be sufficient). We also select "Use an existing virtual hard drive file" and select the simpleArbiterDhcp and press Create.

-
- slika-10 -

We run DHCP Server virtual machine and login using "root" ad username and "kaboom" as password.

-

At first, our machine has no assigned IP, since none was set! Let+s configure it in /etc/network/interfaces.
But which interface should we configure? Using ifconfig -a command, we see it's eth0interface.
- Again we select our IP address.

- slika-11 -

We save the configuration file. Our computer still has no IP address assigned to eth0, so using ifdown eth0 and then ifup eth0we provide one.

- slika-12 -

Now let us use ifconfig command, to check whether there is an IP assigned to interface eth0

- slika-13 -

We got it! We install DHCP server using apt-get install isc-dhcp-server

- slika-14 -

We see a bunch of errors. Why? Bacause, we have no internet access!
- We need to specify the Gateway for our inteface. Our Gateway will be set as IP of our simpleArbiter virtual machine.
We do this using theroute add default gw 192.168.251.1 eth0 command

- slika-15 -

Try pinging Google's DNS server at 8.8.8.8, to check if now have internet access.
- We do this using the ping 8.8.8.8 command.

- slika-16 -

Google's DNS server is responding. Great!
- However, we still cannot run apt-get install isc-dhcp-server
- Let's tempororly add another interface and set it to NAT, so we get internet access and install the DHCP server.

- We add a new interface by turning off the virtual computer, in VirtualBox we select our virtual machine and then select Settings -> Network
- Adapter 1 has already been set to Internal Network, we set Adapter 2 to NAT

- slika-17 -

We run DHCP Server and in file/etc/network/interfaces at the end of the line add iface eth1 inet dhcp, then save the file and run ifup eth1.
- Now we have access to the internet and can install our DHCP server with apt-get install isc-dhcp-server install command
- slika-18
-

Let's see what's in/var/log/syslog, which is a file where our system information is stored in.

- slika-19
-

Looks like we need to set up a DHCP server and specify where it should listen!
- DHCP settings are stored in /etc/dhcp/dhcpd.conf. Let's set it!
- First let's comment out option domain-name-servers to avoid having errors.

- slika-20
-

Then we configure DHCP server, so it would serve IPs a a certain subnet. We add the following lines:

- slika-21 -

(subnet) We set the subnet and the IP range, which the DHCP server should use, and which file it should serve.

Some PXEs are so unintelligent, that you should specify where they should get the files from and to do that you specify next-server
(IP from which it will be served from, in our case simpleArbiter), we also specify gateway, which, in our case is also simpleArbiter.

Since we would like, that in the case of BootableClient B another file to be served, we do it by defining a special host like this:
(host special) Under hardware ethernet we specifiy MAC address of our BootableClient B, we assign it a static ip and where the file live-ISO is located.

-

We save the settings and kill the process named dnsmasqusingkilall dnsmasq.

- slika-22 -

We restart our DHCP server, to apply the new settings. This is done using service isc-dhcp-server restart
command. DHCP server is now ready! We supply BootableClientA and BootableClientB and test them!

- - -

Setting up BootableClient A

-

We open VirtualBox and select New, for the -Name field we specify -BootableClient A and for the Hard drive we select Do not add a -virtual -hard drive (as we want diskless device),
and select Create. -We want the computer to be on Internal network so vse select our -Bootable Client -A and select
Settings->Network where we change Adapter -1 to Internal Network.

- slika-23 -

We also want our computer to boot through the network, so -underBoot Ordertab select Network.
- We save the setting by clicking OK

- slika-24 -

We run our BootableClient-a A and it get's it's -IP(which is great), using the DHCP server and the simpleArbiter serves -it exactly the file we specified. A.0

- slika-25 - - - -

Setting upBootableClient -B

-

We open virtual box and select New and under the Name tag write BootableClient B and under the Hard drivetab choose Do not add a virtual hard drive (since we want a diskless machine),
and then press the Create button, which will create a virtual machine. We want our machine to be connected to out Internal network so we select Bootable Client B and then select
Settings->Network and set the Adapter 1 to Internal Network.
- Under MAC Address we specify the same MAC address that is specified in the (dhcpd.conf -> host special) file, since we want our machine to be an exception
and will be served a special file namedlive-ISO

- slika-26 -

We want our machine to perform a netboot, so under the System

Boot Order tag specify only Network.
- We save the setting by clicking the OK button

- slika-27 -

We run our BootableClient-a A and it get's it's IP address using DHCP server and simpleArbiter serves it the file we selected called live-ISO

We download simpleArbiterDhcp.vdi ter zaženemo VirtualBox. Ko je datoteka prenesena v VirtualBoxu izberemo New ter v polje Name vpišemo DHCP Server.
Ustrezno nastavimo tudi Memory size (1gb pomnilnika nam bo zadostovalo). Spodaj izberemo še "Use an existing virtual hard drive file" ter izberemo naš simpleArbiterDhcp in pritisnimo Create.

We run DHCP Server virtual machine and login using "root" ad username and "kaboom" as password.

-

At first, our machine has no assigned IP, since none was set! Let+s configure it in /etc/network/interfaces.
But which interface should we configure? Using ifconfig -a command, we see it's eth0interface.
- Again we select our IP address.

- slika-11 -

We save the configuration file. Our computer still has no IP address assigned to eth0, so using ifdown eth0 and then ifup eth0we provide one.

- slika-12 -

Now let us use ifconfig command, to check whether there is an IP assigned to interface eth0

- slika-13 -

We got it! We install DHCP server using apt-get install isc-dhcp-server

- slika-14 -

We see a bunch of errors. Why? Bacause, we have no internet access!
- We need to specify the Gateway for our inteface. Our Gateway bo seveda IP našega simpleArbiter navideznega računalnika.
To naredimo s pomočjo ukaza route add default gw 192.168.251.1 eth0

- slika-15 -

Try pinging Google's DNS server at 8.8.8.8, to check if now have internet access.
- We do this using the ping 8.8.8.8 command.

- slika-16 -

Google's DNS server is responding. Great!
- However, we still cannot run apt-get install isc-dhcp-server
- Let's tempororly add another interface and set it to NAT, so we get internet access and install the DHCP server.

- We add a new interface by turning off the virtual computer, in VirtualBox we select our virtual machine and then select Settings -> Network
- Adapter 1 has already been set to Internal Network, we set Adapter 2 to NAT

- slika-17 -

We run DHCP Server and in file/etc/network/interfaces at the end of the line add iface eth1 inet dhcp, then save the file and run ifup eth1.
- Now we have access to the internet and can install our DHCP server with apt-get install isc-dhcp-server install command
- slika-18
-

Let's see what's in/var/log/syslog, which is a file where our system information is stored in.

- slika-19
-

Looks like we need to set up a DHCP server and specify where it should listen!
- DHCP settings are stored in /etc/dhcp/dhcpd.conf. Let's set it!
- First let's comment out option domain-name-servers to avoid having errors.

- slika-20
-

Then we configure DHCP server, so it would serve IPs a a certain subnet. We add the following lines:

- slika-21 -

(subnet) We set the subnet and the IP range, which the DHCP server should use, and which file it should serve.

Some PXEs are so unintelligent, that you should specify where they should get the files from and to do that you specify next-server
(IP from which it will be served from, in our case simpleArbiter), we also specify gateway, which, in our case is also simpleArbiter.

Ker bi radi, da v primeru zagona navideznega računalnika BootableClient B serviramo drugo datoteko, to naredimo tako da definiramo nek dodaten host na sledeč način:
(host special) Pod hardware ethernet zapišemo MAC naslov našega BootableClient B katerega bo imel, dodelimo mu nek statičen ip naslov ter povemo še iz kje se naj datoteka live-ISO zažene.

-

We save the settings and kill terthe process with ubijemo named dnsmasqusingkilall dnsmasq.

- slika-22 -

Sledi restart našega DHCP strežnika, da bo deloval z novimi nastavitvami, to naredimo z ukazom service isc-dhcp-server restart
DHCP server is now ready! We supply BootableClientA and BootableClientB and test them!

- - -

Postavitev BootableClient A

-

We open VirtualBox and select New, for the y -Name field we specify -BootableClient A and for the Hard drive we select Do not add a -virtual -hard drive (as we want diskless device),
and select Create. -We want the computer to be on Internal network so vse select our -Bootable Client -A and select
Settings->Network where we change Adapter -1 to Internal Network.

- slika-23 -

We also wan our computer to boot through network, so -underBoot Ordertab select Network.
- We save the setting by clicking OK

- slika-24 -

We run our BootableClient-a A and it get's it's -IP(which is great), using the DHCP server and the simpleArbiter serves -it exactly the file we specified. A.0

- slika-25 - - - -

Setting upBootableClient -B

-

Odpremo VirtualBox ter izberemo New in pod Name napišemo BootableClient B ter pod Hard drive izberemo Do not add a virtual hard drive (saj si želimo računalnik brez diska),
in pritisnemo na gump Create, da se nam ustvari navidezni računalnik. Želimo, da bo računalnik priklopljen na Internal network zato označimo naš Bootable Client B ter pritisnimo na
Settings->Network in prvi Adapter 1 spremenimo na Internal Network.
- Poleg tega nastavimo še pod MAC Address takšen MAC naslov, kot ga imamo v nastavitvah DHCP strežnika (dhcpd.conf -> host special), saj želimo da bo ta naš računalnik izjema
in bo ob zagonu dobil drugo datoteko kot ostali in sicer live-ISO

- slika-26 -

Želimo še, da se računalnik boot-a preko mreže, zato to nastavimo pod zavihkom System

tako, da pod Boot Order obkljukamo samo Network.
- Nastavitve shranimo z pritiskom na gumb OK

- slika-27 -

Poženemo našega BootableClient-a A in odličnoo, dobi ip naslov s pomočjo DHCP strežnika in simpleArbiter mu servira točno to datoteko katero si želimo live-ISO

Kako narediti live boot z DHCP strežnikom.

- - -

Potrebujemo program VirtualBox ter naslednje 4 navidezne računalnike: -

-

- -

Skica našega podomrežja

- slika-01 -

Naš cilj je, da računalnik BootableClient A preko DHCP strežnika pridobil IP naslov ter se zažene z datoteko A, ki se nahaja na simpleArbiterGW,
če pa zaženemo računalnik BootableClient B pa si želimo, da ta preko DHCP strežnika pridobi IP naslov ter se zažene z nekim live ISO, ki se prav tako nahaja na simpleArbiterGW. -

- -

Postavitev simpleArbiterGW

-

Prenesemo simpleArbiterGW.vdi ter zaženemo VirtualBox. Ko je datoteka prenesena v VirtualBoxu izberemo New ter v polje Name vpišemo simpleArbiterGW.
Ustrezno nastavimo tudi Memory size (1gb pomnilnika nam bo zadostovalo). Spodaj izberemo še "Use an existing virtual hard drive file" ter izberemo naš simpleArbiterGW.vdi in pritisnimo Create.

-
- slika-02 -

Nato zaženemo virtualni računalnik simpleArbiterGW ter se z uporabniškim imenom "root" ter geslom "kaboom" vpišemo v naš sistem.

- Prvo računalnik od NAT-a, kateri je vgrajen v VirtualBox dobi nek naslov (v našem primeru 10.0.2.15).
(Da to preverimo uporabimo ukaz ifconfig) Preko tega IP naslova in vmesnika eth0 smo povezani v internet.

- slika-03 -

Mi pa si želimo 2 omrežna vmesnika na tem računalniku! Enega bi radi imeli na NAT (tega že imamo) drugega pa na Internal Network,
preko katerega bomo komunicirali z DHCP Strežnikom ter ostalimi računalniki, ki bodo v našem Internal Network-u.

- Nov omrežni vmesnik dodamo tako, da ugasnemo naš virtualni računalnik, ter v VirtualBoxu označimo naš virtualni računalnik in pritisnemo na Settings -> Network
- Adapter 1 imamo že nastavljeno na NAT, Adapter 2 pa nastavimo na Internal Network

- slika-04 -

Tako, zdaj imamo nastavljena 2 vmesnika!
V VirtualBoxu lahko definiramo več Internal Networkov (notranjih omrežij) a za naše potrebe bo to dovolj. Shranimo nastavitve ter ponovno poženimo naš simpleArbiterGW.

- Zdaj moramo oba omrežna vmesnika nastaviti tako, da bosta imela nek naslov. Uredimo datoteko interfaces v imeniku - /etc/network.

- slika-05 -

Za eth0 je poskrbel že DHCP strežnik, ki je vgrajen v VirtualBox (na eth0 je določil nek IP).
- Mi moramo nastaviti še drugi mrežni vmesnik. Kako se imenuje iz glave ne vemo zato s pomočjo ukaza ifconfig -a pogledamo.

- slika-06 -

Ugotovimo da je ime vmesnika eth1. - Zdaj bi rad na eth1 nastavil en IP naslov.
- Lahko bi nastavil z ifconfig, a ko rebootaš računalnik se nastavitve ne ohranijo. To nebi radi!
- Pojdimo raje skonfigurirat nastavitve v /etc/network/interfaces

- Izmislimo si eno naključno lokalno omrežje oz naslov lokalnega omrežja ter nastavimo eth1. -

- slika-07 -

Shranimo konfiguracijsko datoteko. Moj računalnik še nima IP-ja na eth1 zato uporabim ukaz ifup eth1

- slika-08
-

Sedaj uporabimo ukaz ifconfig, da vidimo če imamo slučajno ip na vmesniku eth1

- slika-09 -

Vidim, da ip imam. Super! Gremo postavit DHCP Server!

- -

Postavitev DHCP Server

-

Prenesemo simpleArbiterDhcp.vdi ter zaženemo VirtualBox. Ko je datoteka prenesena v VirtualBoxu izberemo New ter v polje Name vpišemo DHCP Server.
Ustrezno nastavimo tudi Memory size (1gb pomnilnika nam bo zadostovalo). Spodaj izberemo še "Use an existing virtual hard drive file" ter izberemo naš simpleArbiterDhcp in pritisnimo Create.
Ustrezno nastavimo tudi nastavitve mreže iz NAT na Internal Network

-
- slika-10 -

Nato zaženemo virtualni računalnik DHCP Server ter se z uporabniškim imenom "root" ter geslom "kaboom" vpišemo v naš sistem.

-

Sprva naš računalnik nima nobenega ip-ja saj mu ga nismo nastavili! Pojdimo skonfigurirat nastavitve v /etc/network/interfaces.
Ampak kateri vmesnik sploh konfiguriramo? Z ukazom ifconfig -a ugotovimo da je to eth0.
- Spet si izberemo nek svoj statičen ip naslov.

- slika-11 -

Shranimo konfiguracijsko datoteko. Moj računalnik še nima IP-ja na eth0 zato uporabim ukaz ifdown eth0 ter nato še ifup eth0

- slika-12 -

Sedaj uporabimo ukaz ifconfig, da vidimo če imamo slučajno ip na vmesniku eth0

- slika-13 -

Hura imamo! Namestimo naš DHCP strežnik z ukazom apt-get install isc-dhcp-server

- slika-14 -

Vidimo, da dobimo cel kup napak. Ampak zakaj? Zato, ker nimamo dostopa do interneta!
- Vmesniku eth0 moramo seveda povedati Gateway. Naš Gateway bo seveda IP našega simpleArbiter navideznega računalnika.
To naredimo s pomočjo ukaza route add default gw 192.168.251.1 eth0

- slika-15 -

Probajmo ping-ati Googlov DNS strežnik, da ugotovimo če imamo sedaj internet.
- To naredimo z ukazom ping 8.8.8.8.

- slika-16 -

Googlov DNS strežnik se odziva, super!
- Ampak apt-get install isc-dhcp-server še vedno ne moremo naložiti.
- Začasno dodajmo še en mrežni vmesnik ter ga nastavimo na NAT, nato bomo dobili dostop do interneta ter lahko namestimo naš DHCP strežnik.

- Nov omrežni vmesnik dodamo tako, da ugasnemo naš virtualni računalnik, ter v VirtualBoxu označimo naš virtualni računalnik in pritisnemo na Settings -> Network
- Adapter 1 imamo že nastavljeno na Internal Network, Adapter 2 pa nastavimo na NAT

- slika-17 -

Zaženemo naš DHCP Server in v /etc/network/interfaces začasno na koncu dodamo vrstico iface eth1 inet dhcp,datoteko shranimo ter poženemo ukaz ifup eth1.
- Sedaj imamo dostop do interneta in lahko namestimo naš DHCP strežnik z ukazom apt-get install isc-dhcp-server install
- slika-18
-

Poglejmo kaj je v /var/log/syslog, to je datoteka kamor se shranjujejo sporočila kaj se dogaja v našem sistemu

- slika-19
-

Očitno moramo nastaviti dhcp strežnik ter mu povedati tudi kam naj posluša!
- Za nastavitve DHCP strežnika imamo /etc/dhcp/dhcpd.conf. Nastavimo jo!
- Prvo zakomentiramo option domain-name-servers zaradi tega da nebo napak da jih ne najde.

- slika-20
-

Nato skonfiguriramo dhcp strežnik, da bo serviral ip-je na nekem podomrežju. Dodamo naslednje zapise:

- slika-21 -

(subnet) Nastavimo podomrežje ter območje naslovov od koder naj jih DHCP strežnik dodeli, katero datoteko naj servira,
poleg tega so eni PXE tako neumni, da če jim ti serviraš filename nevejo iz katerega serverja ga dobim, zato napišem še next-server
(ip od koder serviram, v našem primeru simpleArbiter), nastavim tudi gateway kateri je v našem primeru tudi simpleArbiter.

Ker bi radi, da v primeru zagona navideznega računalnika BootableClient B serviramo drugo datoteko, to naredimo tako da definiramo nek dodaten host na sledeč način:
(host special) Pod hardware ethernet zapišemo MAC naslov našega BootableClient B katerega bo imel, dodelimo mu nek statičen ip naslov ter povemo še iz kje se naj datoteka live-ISO zažene.

-

Spremembe shranimo, ter ubijemo proces z imenom dnsmasq z ukazom kilall dnsmasq.

- slika-22 -

Sledi restart našega DHCP strežnika, da bo deloval z novimi nastavitvami, to naredimo z ukazom service isc-dhcp-server restart
DHCP Strežnik je pripravljen! Pripravimo BootableClientA ter BootableClientB ter testirajmo!

- - -

Postavitev BootableClient A

-

Odpremo VirtualBox ter izberemo New in pod Name napišemo BootableClient A ter pod Hard drive izberemo Do not add a virtual hard drive (saj si želimo računalnik brez diska),
in pritisnemo na gump Create, da se nam ustvari navidezni računalnik. Želimo, da bo računalnik priklopljen na Internal network zato označimo naš Bootable Client A ter pritisnimo na

tako, da pod Boot Order obkljukamo samo Network.
- Nastavitve shranimo z pritiskom na gumb OK

Poženemo našega BootableClient-a A in odličnoo, dobi ip naslov s pomočjo DHCP strežnika in simpleArbiter mu servira točno to datoteko katero si želimo A.0

in pritisnemo na gump Create, da se nam ustvari navidezni računalnik. Želimo, da bo računalnik priklopljen na Internal network zato označimo naš Bootable Client B ter pritisnimo na
Settings->Network in prvi Adapter 1 spremenimo na Internal Network.
- Poleg tega nastavimo še pod MAC Address takšen MAC naslov, kot ga imamo v nastavitvah DHCP strežnika (dhcpd.conf -> host special), saj želimo da bo ta naš računalnik izjema
in bo ob zagonu dobil drugo datoteko kot ostali in sicer live-ISO

- slika-26 -

Želimo še, da se računalnik boot-a preko mreže, zato to nastavimo pod zavihkom System

tako, da pod Boot Order obkljukamo samo Network.

Postavitev TFTP strežnika in zagonskih datotek

- -

Na SimpleArbiter namestimo TFTP strežnik z ukazom apt-get install tftpd-hpa in spremenimo IP v "/etc/default/tftpd-hpa" pod TFTP_ADDRES na "192.168.251.1". -
Nato z ukazom apt-get install syslinux namestimo syslinux in skopiramo zagonsko datoteko iz "/usr/lib/syslinux/pxelinux.0" na "/srv/tftp/A.0.
Namestimo še NFS server z ukazom "apt-get install nfs-kernel-server" in v "/etc/exports" dodamo lokacijo mape, kjer se nahaja naša zagonska datoteka A.0, ter omogočimo branje ("/srv/tftp * (ro)"). -
V imeniku /srv/tftp ustvarimo mapo "pxelinux.cfg" in v njej ustvarimo datoteko z imenom default. Vanjo vpišemo : -

Purpose of the exercise

-

How to setup a LDAP Server, to add entries to a LDAP Server, and to change users' rights to be able to add entries and change the attributes of entries.

- -

How To

- -
    -
  1. Create two virtual machines, SimpleArbiterDhcpGWLDAP(simpleArbiterDhcpGWLDAP.vdi) and LDAPServer(student-LDAPServer.vdi). -
    No img
    2. -
    -
  2. Change the network settings to both virtual machines. SimpleArbiterDhcpGWLDAP: Adapter 1 is set to "NAT" for internet access and - adapter 2 to "internal network" for local network. LDAPServer: Adapter 1 set to "internal network" sot that it is in the same internal network as SimpleArbiterDhcpGWLDAP. -

    No img
    3. -
    -
  3. In SimpleArbiterDhcpGWLDAP log in as user "tester", in LDAPServer log in as user "root", run the command "apt-get update" to update the list of packages and - open up another terminal by pressing "ALT+F2" and log in as user "student".
    4. -
    -
  4. In LDAPServer run the command "apt-get install slapd ldap-utils" to install these packages which are the LDAP server and tools to access and manage the LDAP server. -
    During the LDAP server installation you'll have to provide the password for the user "admin", the administrator of the server and confirm the password chosen.
    5. -
    -
  5. Configure the LDAP server by choosing the appropriate domain name and other configuration parameters. Execute the commmand "dpkg-reconfigure slapd". -

    a) If you will configure the "slapd" again don't forget to remove the old database "rm -rf /var/backups/unknown-2.4.44+dfsg-2.ldapdb".
    6. -
    -
  6. Now that the LDAP server is configured for use, try to open a third console and log in as user "student" and execute the command "ldapsearch -D cn=admin,dc=ceres-20,dc=kpov, - dc=lusy,dc=fri,dc=uni-lj,dc=si -W -b dc=ceres-20,dc=kpov,dc=lusy,dc=fri,dc=uni-lj,dc=si", which will show the entries in the server. -
    Because you will be using a lot the domain name to access the LDAP server you can set the environment variable "D", which will allow for quicker typing of commands. -
    "export D=dc=ceres-20,dc=kpov,dc=lusy,dc=fri,dc=uni-lj,dc=si" -
    "ldapsearch -D cn=admin,$D -wvaje -b $D"
    7. -
    -
  7. Create the file(LDIF format) "users.ldif" which will contain the objects(users) that we want to add to the LDAP server database. -
    No img -
    Execute the following command to add users to the LDAP server: -
    "ldapadd -D cn=admin,$D -wvaje -f users.ldif" -
    Add password to the users added to the LDAP server: -
    "ldappasswd -D cn=admin,$D -wvaje -sj2531e cn=ninavidmar,ou=users,$D" -
    "ldappasswd -D cn=admin,$D -wvaje -scTyRM0 cn=natalijaribnikar39,ou=users,$D" -
    Execute command "ldapsearch -D cn=natalijaribnikar39,ou=users,$D -wcTyRM0 -b $D" to bind to the LDAP server with the newly added user "natalijaribnikar39" and to see the entries currently in the LDAP server. -
    No img
    8. -
    -
  8. In order to change the users' rights settings, which allows a user to add entries to the directory and change values of attributes of entries in the directory you need to create an additional file acl.ldif: -
    To see which backend database is used and other settings related to the users' rights execute command "ldapsearch -Y EXTERNAL -H ldapi:/// -b cn=config" as root user in the system, which does not need the user authentication to the LDAP server. -
    No img -
    The settings in the acl.ldif file: -
    No img -
    Now to change users' rights run the command "ldapmodify -Y EXTERNAL -H ldapi:/// -f acl.ldif" as user "root" in the system.
    9. -
    -
  9. The user "natalijaribnikar39" has the right to add or change objects in the LDAP server. -
    Now try to bind to the LDAP server using "natalijaribnikar39" user's credentials and add a new user to the server directory. -
    "ldapadd -D cn=natalijaribnikar39,ou=users,$D -wcTyRM0 -f newuser.ldif"
    10. -
    -
  10. Now to test your result go to the SimpleArbiterDhcpGWLDAP virtual machine and run "./test_task.py" to run the test and see your score. -

MOCK ENTRANCE EXAM - HOWTO

 - -

1) POSTAVITEV VIRTUALK

- -Najprej prenesi obe sliki za virtualki iz sistema kpov-judge, 2. naloga. Če se sliki ne naložita takoj, malo počakaj in osveži stran. -Ustvari novo virtualko imenovano "Student", tip je načeloma "Linux" ter verzija "Ubuntu (64-bit)" - lahko pa je tudi karkoli drugega. Določi ustrezno količino pomnilnika, ki bo na voljo napravi, izberi možnost rabe obstoječe slike navidezne naprave ter izberi prenešeno datoteko "student-entrance.vdi". Klikni ustvari.
ni slike
-Prejšnji postopek ponovi še za "SimpleArbiter", "Linux", "Ubuntu (64-bit)", "simplearbiter.vdi".
ni slike
- -

2) OMREŽNE NASTAVITVE VIRTUALK

- -V navodilih naloge lahko vidimo, da morata biti obe virtualki povezani v internet ter povezani med seboj prek nekega notranjega omrežja. -Na "SimpleArbiter" nastavimo pod Settings->Network->Adapter 1; Enable network adapter "check", Attached to: NAT. ->Adapter 2; Enable network adapter "check", Atached to: Internal Network.
ni slike ni slike
-Na "Student" je postopek nastavitve enak kot na "SimpleArbiter".
ni slike ni slike
- -OPOMBA: Pozoren je treba biti, da sta oba vmesnika, ki sta povezana na notranje omrežje (Internal Nerwork) povezana preko istega omrežja, npr. "intnet". - -

3) ZAGON VIRTUALK IN POSOTPEK NALOGE

- -SA - SimpleArbiter -STUD - Student - -Najprej zaženemo obe vritualki, to storimo s klikom na gumb start. -Na SA se prijavimo z uporabniškim imenom "tester" ter geslom "tester" - -

3.1) POSKRBIMO ZA MREŽO

- -

3.1.1) SPREMEMGA GESLA ZA ROOT

- -Z uporabo ukaza /sbin/ifconfig preverimo, ali so vmesniki pravilno nastavljeni. Kaj kmalu ugotovimo, da je na SA aktiven samo en vmesnik. Za nastavljanje omesnikov moramo najprej postati "root", torej uporabnik, ki ima pooblastila za urejanje sistemskih nastavitev. -Najprej ponovno zaženemo virtualko: "sudo reboot", potrdimo z geslom "tester". -V GRUB meniju (zagonski meni) nato pritisnemo tipko "e", ki omogoča spreminjanje ukazov pred zagonom. Vrstico "53d ro" spremenimo v "53d rw init=/bin/bash". Pritisnemo "F10" in sprožimo zagon naprave. -Sedaj lahko kot super uporabnik zamenjaš geslo za root, to storiš z ukazom "passwd", sistem te nato vpraša za novo geslo, po vnosu pa še za potrditev gesla. Geslo je uspešno spremenjeno, spremembe pa je potrebno še shraniti na disk, to storiš z ukazom "mount -o remount,ro /", izvedi še ukaz "sync", da se podatki res zapišejo na disk. Sedaj lahko virtualko ponovno zaženeš kar iz Machine->Reset. - -

3.1.2) NASTAVIMO OMREŽNE VMESNIKE

- -V virtualko SA se sedaj prijavimo kot uporabnik "root" ter s spremenjenim geslom "karsinastavil". -Sedaj spremenimo nastavitve omrežnih vmesnikov tako, da bodo naslovi ustrezali tistim v navodilih. Izvedemo ukaz "ifconfig enp0s8 10.0.2.129 netmask 255.255.255.128 up" -Preklopimo na virtualko STUD (uporabnik "root", geslo "kaboom") ter izvedemo podoben ukaz "ifconfig enp0s8 10.0.2.X netmassk 255.255.255.128", kjer je X podatek iz navodil naloge. -Notranje omrežje testiramo tako, da pošljemo ping iz SA do STUD z ukazom "ping NASLOV", kjer je NASLOV omrežni naslov na STUD, ki je povezan na notranje omrežje (nastavitev iz prejšnjega koraka). -SUPER, omrežje deluje, gremo naprej. Če ne deluje, preveri pravilnost naslovov na SA in STUD, bodi pozoren na dolžino maske ter na morebitne zatipke. - -

3.2) "ZLONAMERNI" PROGRAM

- -V navodilih naloge je podano ime programa, ki naj bi ob svojem zagonu pokvaril nastavitve omrežnih vmesnikov na STUD. Z ukazom "ps xa | grep IMEPROGRAMA" preverimo, če se program izvaja. V izpisu ugotovimo, da se najvrjetneje ne izvaja, zato lahko zadevo ignoriramo. Če bi se program izvajal, bi bilo potrebno ukrepati ter ga na nek način izbrisati oz. mu onemogočiti spreminjanje omrežnih vmesnikov (najlažje bi bilo uporabiti ukaz "kill", ki kot argument prejme PID (prvi stolpec prejšnjega izpisa) ter konča izvajanje tega procesa). Več o ukazu "kill" si preberi na spletu! - -

3.3) PREVAJANJE PROGRAMA

- -Najprej si odpremo novo konzolo na STUD "alt+F2" ter se prijavimo kot "student" z geslom "vaje". -Z ukazom "ls" preverimo vsebino domačega direktorija uporabnika student. Izpisati bi se morala datoteka, ki jo imamo podano v navodilih. To datoteko moramo najprej odpreti z ukazom "vim IMEDATOTEKE". Datoteko moramo sedaj popraviti tako, da odstranimo odvečne črke, to storimo tako, da izvedemo ukaz ":%s/[QXW]*//g", sedaj izvedemo še ":syn on" in si obarvamo kodo. Izhod iz urejevalnika ":wq". -Ta program sedaj z ukazom "gcc IMEPREVEDENEGAPROGRAMA IMEDATOTEKE" prevedemo v nov program, kjer je IMEPREVEDENEGAPROGRAMA izhodni program, katerega ime je prav tako podano v navodilih, IMEDATOTEKE pa ime pravkar popravljene datoteke. - -

3.4) SKRIPTA

- -Sedaj bomo napisali nov program/skripto, uporabimo urejevalnik nano; "nano IMESKRIPTE", kjer je IMESKRIPTE podano v navodilih naloge. -V skripto zapišemo sledeče;
-
-----BREZ TE VRSTICE-------
-
-#!/bin/bash
-
-echo -n $SPREMENLJIVKA | /home/student/IMEPREVEDENEGAPROGRAMA "argument" 2> /home/student/IMEDATOTEKE_STDERR | grep "ma" > /home/student/IMEDATOTEKE_STDOUT
-
-----BREZ TE VRSTICE-------
-
-Datoteko shranimo "ctrl+x" ter potrdimo z "y" in enter. -Datoteko sedaj spremenimo v program "chmod +x IMESKRIPTE" - -

4) TESTIRANJE NALOGE

NAT VLC:

 -

Explanation:


- Set up a computer so that it forwards all packets meant for a certain address, to another computer.

-

Instructions:

-

1. Create two VMs. SimpleArbiter using the disk simpleArbiter and NATServer.

- You can get the disks at polz.si/media/uploads/kpov/virtualke. As for the NATServer VM, you can use any disk you want like base-student-desktop-2014. -
-

2. NATServer should have two network interfaces, one should connect to the simpleArbiter VM and the other to the internet.

- Adapter 1 should be NAT and adapter 2 should be Internal Network.
- Simple Arbiter must be connected to the Internal Network. -
- slika-1 -

3.On NATServer use ifconfig or /etc/network/interfaces to configure the network interfaces you created in virtualbox.

- - -vim /etc/network/interfaces
- -Set it up like this:
- auto eth1
- iface eth1 inet static
- NETMASK 255.255.0.0 # Specify based on your requirement
- IPADDR 192.168.2.1 # Gateway of the LAN
- NETWORK 192.168.0.0 # Optional
- ADDRESS 192.168.0.0
- -ifdown eth1
- -ifup eth1 -
-slika-2 -

4. Configure SimpleArbiter so that it uses NATServer as the default gateway.

- -

5. Set up DNS (etc/resolv.conf) on NATServer.

- vim /etc/resolv.conf - nameserver 203.145.184.13 # Primary DNS Server provided by the ISP
- nameserver 202.56.250.5 # Secondary DNS Server provided by the ISP
- Than we set up the host:
- vim /etc/hosts
- Replace the first line with:
- 127.0.0.1 nat localhost.localdomain localhost
- -

6. Enable IP forwarding on NATServerju (should be run as root).

- echo 1 > /proc/sys/net/ipv4/ip_forward - -

7. Set up NAT on NATServer using iptables.

- - apt-get install iptables
- iptables -F
- ptables -t nat -F
- iptables -t mangle -F
- iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
- iptables -A FORWARD -i eth1 -j ACCEPT

- - service iptables restart - -

8. Use vlc on simpleArbiter to watch the video over your network.

NAT VLC:

 -

Naloga na hitro:


- Nastavi računalnik tako, da bo vse pakete za določene naslove prepošiljal na drug računalnik, vzpostavi NAT.

-

Navodila:

-

1. Postavi dva navidezna računalnika. SimpleArbiter z diskom simpleArbiter ter NATServer.

- Virtualke dobiš na (polz.si/media/uploads/kpov/virtualke). Za NATServer lahko uporabiš base-student-desktop-2014. -
-

2. Postavi NAT server tako, da ima dva omrežna vmesnika. Z enim naj bo povezan na simpleArbiter, z drugim pa na internet.

- (settings-Network) Adapter 1 nastavimo na NAT (omrežje), adapter 2 pa na InternalNetwork (lokalno).
- Simple Arbiter nastavimo na InternalNetwork(lokalno). -
- slika-1 -

3.Na NATServer z ukazom ifconfig in z datoteko /etc/network/interfaces skonfiguriraj omrežne vmesnike
- tako, da bo en povezan v WAN (internet) in en vmesnik na LAN (simpleArbiter).

4. SimpleArbiter skofiguriraj tako, da bo privzeti prehod uporabljal NATServer.

- Nastavi gateway, da ima IP od NATServerja.
- route add -net IP netmask MASK default gw IP dev eth0
- -

5. Nastavi DNS (etc/resolv.conf) na NATServerju.

- vim /etc/resolv.conf - nameserver 203.145.184.13 # Primary DNS Server provided by the ISP
- nameserver 202.56.250.5 # Secondary DNS Server provided by the ISP
- Nato nastavimo še host:
- vim /etc/hosts
- Prvo vrstico zamenjamo z:
- 127.0.0.1 nat localhost.localdomain localhost
- -

6. Omogoči posredovanje IP naslovov na NATServerju.

- echo 1 > /proc/sys/net/ipv4/ip_forward - -

7. Nastavi NAT z uporabo paketa iptables na NATServerju.

- - apt-get install iptables
- iptables -F
- ptables -t nat -F
- iptables -t mangle -F
- iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
- iptables -A FORWARD -i eth1 -j ACCEPT

- - service iptables restart - -

8. Na simpleArbiter z vlc preberi naslov, na katerem si lahko ogledaš kratek filmček.

- - apt-get install vlc-nox
- Nastavitev naslova:
- Open Media > OpenNetwork ....
- - - -

OpenVPN and SMB task:

 -

Quick task:


- Connect to VPN with OpenVPN. Enable access to files through NFS and copy them through SMB.

-

Instructions:


- 1. From Directory with images of virtual computers drag twice the picture SimpleArbiterVPN and VPNClient.
- 2. With VirtualBox (or other programs for virtual computers) create two virtual computers and give them VPNCLient.vdi and SimpleArbiterVPN.vdi as disk for storage.
- 3. On both set two network interface(NAT and Internal) and run them.
- 4. On both VM login with username root and password kaboom .

-

First part: Set up OpenVPN on SimpleArbiterVPN and VPNClient.

-

Settings on the server:

- 1. Download packages uml-utilities -> to adjust the virtual network interfaces and packet (openvpn). example: sudo apt-get install openvpn
- 2. The new virtual network interface create with tunctl and specify IP with sudo ifconfig tap0 10.P.Q.R netmask 255.255.255.0
- 3. Then generirate common key (you will share that key with client) with the command: openvpn --genkey --secret vpnkljuc.key
- 4. On server set the configuration file tap0.conf, which should contain (split by lines) "dev tap0","proto tcp-server", "secret vpnkljuc.key"
- 5. Run openvpn with openvpn --config /some_directory/somewhere/tap0.conf
-

Settings on the client:

-1., 2. steps are the same as the settings on the server
-3. Create configuration file tap0.conf, which should contain (split by lines) "remote IP_OF_YOUR_VPN_SERVR", "dev tap0", "proto tcp-client", "secret vpnkljuc.key"
-4. On OpenVPN server connect to openvpn --config /some_directory/somewhere/tap0.conf
-

- -

Second part: Access to imenika /home/test/IME_IMENIKA over NFS

-

Client settings:

- 1. Using "sudo apt-get install nfs-kernel-server" we install nfs service
- 2. Create a directory /home/test/IME_IMENIKA
- 3. To /etc/exports add line /home/test/bla IP_client - 4. Use sudo exportfs -a to save - 5. Restart service using "sudo service nfs-kernel-server start" -

Client settings:

- 1. Instal client for nfs with command "sudo apt-get install nfs-common"
- 2. Create mounting directory "sudo mkdir -p /mnt/nfs/home/test" and mount servers file "sudo mount IP_SERVER:/home/test"
- 3. For automatic mounting we add previous commands to /etc/fstab

OpenVPN in SMB vaja:

-

Naloga na hitro:


- Vzpostavi VPN povezavo z pomočjo OpenVPN. Omogoči dostop do datotek prek NFS in skopiraj datoteke prek SMB.

-

Navodila:


- 1. Iz imenika s slikami virtualnih računalnikov dvakrat povlecite sliki SimpleArbiterVPN ter VPNClient.
- 2. Z VirtualBoxom (ali ostalim programom za virtualne računalnike) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte VPNCLient.vdi ter SimpleArbiterVPN.vdi.
- 3. Na obeh nastavite dva omrežna vmesnika (NAT in Internal) in jih zaženite.
- 4. Na oba VM-a se prijavite z uporabnikom root in geslom kaboom .

-

Prvi del naloge: Nastavi OpenVPN na SimpleArbiterVPN in VPNClient.

-

Nastavitve na strežniku:

- 1. Prenesite pakete uml-utilities -> za nastavljanje navideznih omrežnih vmesnikov in paket (openvpn). Npr: sudo apt-get install openvpn
- 2. Nov navidezni omrežni vmesnik kreirate z tunctl in mu podate IP z sudo ifconfig tap0 10.P.Q.R netmask 255.255.255.0
- 3. Nato generirate skupen ključ(ta ključ boste delili z klientom) z ukazom: openvpn --genkey --secret vpnkljuc.key
- 4. Na strežniku še nastavite konfiguracijsko datoteko tap0.conf, ki naj vsebuje (ločeno po vrsticah) "dev tap0","proto tcp-server", "secret vpnkljuc.key"
- 5. Zaženete openvpn z openvpn --config /some_directory/somewhere/tap0.conf
-

Nastavitve na klientu:

-1., 2. koraka sta ista kot pri nastavitvah na strežniku
-3. Kreirajte konfiguracijsko datoteko tap0.conf, ki naj vsebuje (ločeno po vrsticah) "remote IP_VAŠEGA_VPN_SERVERJA", "dev tap0", "proto tcp-client", "secret vpnkljuc.key"
-4. Na OpenVPN strežnik se povežete z openvpn --config /some_directory/somewhere/tap0.conf
-

-

Drugi del naloge: Dostop prek NFS do imenika /home/test/IME_IMENIKA

-

Nastavitve na strežniku:

- 1. Z ukazom "sudo apt-get install nfs-kernel-server" namestimo nfs program
- 2. Uredimo mapo exports "sudo nano /etc/exports" in kreiramo direktorij /home/test/IME_IMENIKA
- 3. V datoteko exports dodamo /home/test/bla IP_klienta - 4. Share shranimo z sudo exportfs -a - 5. NFS strežnik štartamo z "sudo service nfs-kernel-server start" -

Nastavitve na klientu:

- 1. Z ukazom "sudo apt-get install nfs-common" namestimo programček nfs-common, da lahko kasneje pripnemo share
- 2. Na klientu moramo urediti še mount tega direktorija: "sudo mkdir -p /mnt/nfs/home/test" in "sudo mount IP_SERVERJA:/home/test"
- 3. Za avtomatski mount ob ponovnem zagonu, dodamo prejšnje ukaze v datoteko /etc/fstab

Radius mysql:

 -

Quick how to:


- Setup the OpenRadius server and add users. Use MySql as the database.

-

Instructions:

 -
    -
  1. Create two virtual machines - SimpleArbiter (use the simpleArbiterDhcp.vdi disk) and RadiusServer. Discs for virtual machines are located on polz.si/media/uploads/kpov/virtualke.
    2. -
  2. Create another two virtual machines using the disks VPNCLient.vdi and SimpleArbiterVPN.vdi.
    3. -
  3. Setup both VMs so that they use two network adapters - NAT and Internal network.
    4. -
  4. Login with the username student and password student on both VMs.
    5. -
- -

Part one: Setup OpenRadius.

-
    -
  1. Install OpenRadius on the RadiusServer VM (configuration files are: /etc/openradius/configuration and /etc/openradius/behaviour)
    2. -
  2. Add a user and assign him a shared secret. This should be configured in the /etc/openradius/configuration file. (More info: http://sites.e-advies.nl/openradius/doc-using-openradius.html )
    3. -
  3. Create a connection from SimpleArbiter to RadiusServer using the secret you configured.
    4. -
-

Part two: Install and setup a MySQL database on RadiusServer

 -
    -
  1. OpenRadius can use the module RadSQL to store users in database.
    2. -
  2. Setup a MySQL server: sudo apt-get install mysql-server.
    3. -
  3. Connect to the MySQL server: mysql -u root -p.
    4. -
  4. Create a database: CREATE DATABASE . Create a table users with columns username and password.
    5. -

Radius mysql:

 -

Naloga na hitro:


- Postaviti je treba RADIUS strežnik in podatkovno bazo.
- Za RADIUS strežnik uporabite FreeRADIUS, za podatkovno bazo pa MySQL. -

-

Navodila:


- 1. Ustvarite dva navidezna računalnika z imenom SimpleArbiter in RadiusServer.
- Za SimpleArbiter uporabite simpleArbiterDhcp, za RadiusServer pa lahko uporabite poljubno virtualko.
- ( virtualke dobiš na polz.si/media/uploads/kpov/virtualke)
- 2. Z VirtualBoxom (ali ostalim programom za virtualne računalnike) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte simpleArbiterDhcp.vdi ter base-student-console-2014.vdi.
- 3. Na obeh nastavite dva omrežna vmesnika (NAT in Internal) in jih zaženite.
- 4. Na oba VM-a se prijavite z uporabnikom student in geslom vaje .

-

Prvi del naloge: Postavi OpenRadius.

- 1. Namesti FreeRadius na virtualki RadiusServer z ukazom "sudo apt-get install freeradius".
- ( pomembni sta dve konfiguracijski datoteki /etc/openradius/configuration in /etc/openradius/behaviour
- 2. Dodaj uporabnika in mu dodaj skupno skrivnost v /etc/openradius/configuration datoteko (več o dodajanju lahko izveš na: "http://sites.e-advies.nl/openradius/doc-using-openradius.html"
- 3. Nato se z to skrivnostjo povežete iz SimpleArbiter na RadiusServer
- - Namestimo freeradius z ukazom apt-get install freeradius-mysql - V datoteku /etc/freeradius/client.conf spremenimo skrivnost (secret) - Nato pa v datoteki /etc/freeradius/users dodamo uporabnika - - -

Drugi del naloge: Namestitev in vzpostavitev baze MySQL na RadiusServer

- 1. Pri OpenRadius-u imamo modul RadSQL, s katerim lahko vzpostavimo hranjenje uporabnikov v bazi
- 2. Namestimo MySQL server z ukazom "sudo apt-get install mysql-server"
- 3. VNato se prijavimo v Mysql server z ukazom mysql -u root -p
- 4. Bazo ustvarimo z ukazom primer: - CREATE DATABASE kwhbRgJY; - GRANT ALL ON kwhbRgJY.* To MajaNovak80@localhost IDENTIFIED BY "y06gmo2Z"; - - - diff --git a/kpov_judge/tasks/radius_mysql_pam/task.py b/kpov_judge/tasks/radius_mysql_pam/task.py deleted file mode 100644 index 5051bb4..0000000 --- a/kpov_judge/tasks/radius_mysql_pam/task.py +++ /dev/null @@ -1,212 +0,0 @@ -# kpov_util should be imported by add_assignment.py - -instructions = { - 'si': '''\ -

Purpose of the assignment

-Learn how to setup network interfaces in most modern Linux distributions (NetworkManager). -

-

-

Quick instructions

-Set a static IP in NetworkManager, set a static IP and DNS server in /etc/network/interfaces. You'll get both IP's when you execute script run_test.py. -

Instructions

-
    -
  1. From the directory with images of virtual computers, download the following:
    maliNetworkManager, maliBrezNetworkManager, SimpleArbiterDhcp.
    2. - -
  2. Set the network for virtual computers, so that SimpleArbiterDhcp's 1. nework interface is connected to the same network, as the only network interface for maliNetworkManager and maliBrezNetworkManager,
    - SimpleArbiterDhcp's 2. network interface will be connected to a NAT or a physical network, where the address and route (gateway) to the internet is obtained via DHCP.
    3. - -
  3. Start SimpleArbiterDhcp. Sign in as user "tester" with password "SedemKrogovPekla".
    4. -
  4. -slika-04
    -Use command 
    ping 193.2.1.66
    to check if SimpleArbiterDhcp is connected to internet. If you get ping reply, you're connected to the internet. Cancel the ping with combination CTRL+C.
    - If SimpleArbiterDhcp doesn't have internet access, change the network settings in Virtual box for 1. and 2. network interface, then restart the virtual computer. - -
    5. -
  5. Run the script run_test.py.
    6. - -
  6. Enter "03.predvaja" as assignment name.
    7. - -
  7. Read the maliNetworkManager's static IP . Leave SimpleArbiterDhcp running in the background until you have setup the maliNetworkManager.
    8. - -
  8. Start maliNetworkManager.
    9. - -
  9. -Sign in the GUI(graphical user interface) using username "student" and password "vaje".
    10. -
  10. ikona network manager
    -Right click on the icon for network settings.
    - -
  11. -Menu NetworkManager
    -Choose "Edit Connections"
    12. - -
  12. -Menu NetworkManager
    -Click "Edit"
    13. - -
  13. -Menu NetworkManager
    -In tab "IPv4" change the "Method" to "Manual". Click "Add". Set the SimpleArbiterDhcp's static IP as static IP A.
    -Add Arnes DNS: 193.2.1.66 to DNS servers. -
    14. -
  14. Click "Save"
    15. - -
  15. Switch to SimpleArbiterDhcp. Click "Enter" or "OK".
    16. - -
  16. Read maliBrezNetworkManager's IP . Click "OK". Read the DNS server's address .
    17. - -
  17. Switch to maliBrezNetworkManager. Switch to first console using combination CTRL+ALT+F1. Sign in as root (su) with password "kaboom".
    18. - -
  18. Open the file /etc/network/interfaces. Edit the settings according to the information you got on SimpleArbiter. Entry for network interface should look something like this:
    -
    -allow-hotplug eth0
-iface eth0 inet static
-    10.0.1.2
-    netmask 255.255.255.128
-    dns-nameservers 10.0.1.5
-
    -
    19. - -
  19. Save the settings. Use the command 
    reboot
    to restart maliBrezNetworkManager. On boot the NetworkManager reads which network interfaces are configured in /etc/network/interfaces. After that NetworkManager doesn't manage these interfaces anymore.
    20. - - -Press OK on SimpleArbiterDhcp. If all went ok, you have completed this assignment. -

    How to use the nano text editor

    -

    - 1.) Open the nano editor with the command nano, which is followed by the path and name of the file. Example: nano /etc/myfile. If the file doesn't exist, the file will be created by the editor.
    - 2.) To move in the editor, we use the arrow keys, backspace is used for deleting.
    - 3.) To save a file press the combination of keys ctrl + O.
    - 4.) To exit the editor press the combination of keys ctrl + X. The editor will ask you, if you really want to exit, you can answer with y (yes ) or with n ( no ).
    - 5.) To cut a line press the combination of keys ctrl + K.
    - 6.) To paste a line press the combination of keys ctrl + U.
    - 7.) To search over a document press the combination of keys ctrl + W and then enter the search string. -

  6. We can check which interface belongs to which adapter in Virtual-box with MAC address. Run ifconfig command and compare the HWaddr value with the value in the Virtual-box ( settings => network => adapter => Mac address )
    no imgno img
    7. -
  7. Then edit the /etc/motd (eg. with nano editor like this: "nano /etc/motd"), file with the specified string. (eg. "Not for Human consumption" )

    8. -
  8. For testing, login with the test user into Test(SimpleArbiterDhcpGw)
    no img
    9. -
  9. Then connect to the Student with ssh, using the user marjankoral19 - ssh marjankoral@ip.

  11. To run Kpov_judge, login onto SimpleArbiterDhcpGw, find and run the file test_task.py ( with ./test_task.py as all other scripts )
    no img
    12. -
  12. A window appears as we can see on the image above, then press Enter, enter your username ( eg. dr6784@student.uni-lj.si ), password, task name (eg. 01-preparation-set_motd), enter the string we should get in motd, enter the username and password of a user on Student(student-console)(eg. marjankoral19), the IP of Student(student-console), and after a brief moment we should get the result. no img

    Kako se uporablja nano urejavalnika besedila:

    -

    - 1.) Urejvalnik Nano odpremo z ukazom nano, kateremu sledi ime datoteke. Primer: nano /etc/mojadatoteka. Če datoteka ne obstaja jo bo ustvaril urejevalnik.
    - 2.) Po urejevalniku se premikamo s smernimi puščicami, brišemo s tipko backspace.
    - 3.) Za shranjevanje dokumenta pritisnemo kombinacijo tipk ctrl + O
    - 4.) Za izhod iz urejevalnika pritisnemo kombinacijo tipk ctrl + X. Pri tem nas urejevalnik upraša, če želimo shraniti spremembe. Odgovorimo z y (yes, ja ) ali z n ( no, ne ).
    - 5.) Za izrez vrstice uporabimo kombinacijo tipk ctrl + K.
    - 6.) Za lepljenje vrstice se uporablja kombinacija tipk ctrl + U.
    - 7.) Za iskanje po besedilu uporabimo kombinacijo tipk ctrl + W, nakar vnesemo iskani niz in pritisnemo tipko enter. -


    -
  6. Kateri vmesnik (npr. eth0) spada pod kateri adapter (npr. Adapter1 ), lahko preverimo s strojnimi naslovi. Na računalniku zaženemo ukaz ifconfig, pogledamo HWaddr vrednost ter jo primerjamo z vrednostjo v Virtual-boxu (nastavitve => omrežja => adapter => MAC address
    ni slikeni slike
    7. -
  7. Nato spremeni datoteko /etc/motd (z urejevalnikom nano, primer uporabe: "nano /etc/motd"), ter zamenjaj niz z ustreznim nizom kot to od tebe zahteva naloga ( npr. "Not for Human consumption" )

-

- Set up two virtual computers - SimpleArbiterDhcp and FileServer. -

-

- Make sure that the directory /srv/nfs/ERLbbBrT on FileServer is accessible - over NFS and over SMB under the sharename urania-03. - Set the SMB server name to zarptica-32. -

-

- SimpleArbiterDhcp should have write access to /srv/nfs/ERLbbBrT over NFS. -

KPOV Judge 7 (SMB NFS)

-

V tej vaji postavimo na linux-u strežnik za nudenje datotek prek mreže in strežnik za SMB, s katerim lahko na Windows sistemih postavimo datoteko v skupno rabo. Pazi da bo simpleArbiterDhcpGW imel NFS pravico pisanja po imeniku!

-

Virtualni računalniki

-

simpleArbiterDhcpGW

-

Naj ima 2 omrežna vmesnika, prvi naj bo preko NAT povezan na svetovni splet, drugi vmesnik pa naj vsebuje interno povezavo znotraj virtualnih sistemov na tvojem računalniku “intnet”.

-

student-fileserver

-

Naj ima 1 omrežni vmesnik, povezan na interno omrežje “intnet”.

Parametri

- Parametri -

Parametri za reševanje naloge

-
-

Tokrat imamo tri parametre. “Imenovani” dir, smb-share, smb-server.

-

Oziroma iz slike so to:

-
    -
  • dir = TeNVU74X
    • -
  • smb-share = aurora-85
    • -
  • smb-server = melete-04
    • -
-

Postopek

-

Ko zaženemo simpleArbiterDhcpGW in student-fileserver se najprej prijavimo v oba sistema. Nato pa na student-fileserver poženemo

- 
apt-get update && apt-get install nfs-kernel-server samba
-

Nastavitve NFS

-

V datoteki /etc/exports dodamo sledečo vrtstico: /srv/nfs/[dir] [IP simpleArbiterDhcpGW](rw).

Datoteko shranimo in znova poženemo NFS strežnik.

- 
service nfs-kernel-server restart
-

Ustvarimo imenik, ki smo ga malce prej navedli v nastavitvah NFS. In nato omogočimo vsem pisanje po tem imeniku.

-
- 
-mkdir /srv/nfs/[dir]
-chmod oug+w /srv/nfs/[dir]
-
-
-

Nastavitve SMB

-

Vse nastavitvene datoteke SMB se nahajajo v imeniku: /etc/samba. Zanima pa nas datoteka smb.conf.

- 
# Datoteka smb.conf
-    [global]
-
-    workgroup = WORKGROUP
-    netbios name = [smb-server] # Nadomestek DNS, ki si ga je izmislil Microsoft
-
-    # Malce nižje pod vrstico =========== Share Definitions =========== dodamo svoje nastavitve
-
-    [[smb-share]] # Primer iz slike: [aurora-85]
-    path = /srv/nfs/[dir]
-    read only = no
-    guest ok = yes
-    browseable = yes
-

Ko popravimo to datoteko restartamo SMB in NetBios s spodnjima ukazoma.

- 
service smbd restart
-service nmbd restart
-

Quick instructions

-

- Set up three virtual computers, SimpleArbiter with the disk image - simpleArbiterDhcp, SNMPServer and SNMPClient. Write a program - called upminutes. This program should output the uptime of the - computer in minutes. Set it up on SNMPClient in the home directory - of the user test with the password test. -

-

- Make sure that the SNMP server reports it's uptime in seconds - over SNMP under NET-SNMP-EXTEND-MIB::nsExtendOutput2Table. -

-

- Write a script called beri.sh that reads the value from the - OID 1.3.6.1.4.1.8072.1.3.2.4.1.2 on SNMPServer. Set it up on - SNMPClient in the home directory of the user test. -

Summary

- -
    -
  1. Set up a virtual machine
    2. -
  2. Install VLC
    3. -
  3. Create RTP video stream
    4. -
  4. Make sure the stream is accessible from the internet
    5. -
- -

Instructions

- -
    -
  1. -

    Set up a virtual machine

    -

    Use disk simpleArbiter. You can get it here.

    -
    2. - -
  2. -

    Install VLC

    -

    - In file /etc/apt/sources.list replace wheezy with - testing or if missing, add rows: -

    -

    - - deb http://ftp.at.debian.org/debian wheezy main contrib non-free
    - deb-src http://ftp.at.debian.org/debian wheezy main contrib non-free -     -

    - slika-01 -

    - Check for updates and install VLC with the following commands: -

    -

    - - apt-get update
    - apt-get install vlc -     -

    -
    3. - -
  3. -

    Create a new stream

    - -

    - Open VLC. In Media menu select Stream. -

    - menu -

    - Here we choose stream source. This can be a file, a network stream or a capture device.
    - For this excercise, add one or more video file by clicking Add ... Continue with a click on button Stream. -

    - stream source -

    - We must also choose the stream destination. For this excercise, choose RTP/MPEG Transport Stream and click Add. - You can configure multiple destinations simultaneously. -

    -

    - Configure destination settings. Enter address and stream name. -

    - stream destination -

    - Next, we can set transcoding, encapsulation, audio and video codecs and also subtitles. When you finish, click Save and Next. -

    - stream settings -

    - In the last step, it is important to check option Stream all elementary streams. - In the text area, we can see the string that can be used to run the stream from a command line. - This is useful if you want to run stream from a computer without graphic interface. -

    - -
    4. - -
  4. -

    Open stream

    -

    - We can now play the stream from another device using VLC. -

    - play stream -

    Ustvari nov tok

    - -

    - Odpri VLC. V meniju Media izberi Stream. -

    - Meni -

    - V oknu "Open Media" izberemo vir toka. Ta je lahko datoteka, že obstoječ omrežni tok ali pa snemalne naprave.
    - Za namen te naloge lahko z klikom na gumb Add ... dodamo eno ali več video datotek. Nadaljujemo z klikom na Stream. -

    - Vir toka -

    - Določiti moramo tudi destinacijo toka. Za to nalogo izberemo RTP/MPEG Transport Stream in kliknemo Add. - Možno je nastaviti več destinacij hkrati. -

    -

    - Nato izpolnimo nastavitve destinacije z naslovom in imenom toka. -

    - Destinacija toka -

    - V naslednjem koraku lahko nastavimo kodiranje, enkapsulacijo, avdio in video nastavitve ter podnapise. -

    - Nastavitve Toka -

    - V zadnjem koraku je pomembno obkljukati možnost Stream all elementary streams. - V spodnjem tekstovnem polju dobimo niz, ki ga lahko uporabimo za zagon toka iz ukazne vrstice. -

    - -

Purpose of this exercise

+

To learn how to use a few BASH commands.

+

Quick summary

+

You will use bash commands like: mv, grep, env etc.

+

Instructions

+ +

    +
  1. Log into your system and in your home folder you will find a directory called Mapa containing 20 files.
    2. +
  2. Rename all files, by replacing all minus signs with underscores using the command: "rename 's/-/_/' *".
    3. +
  3. Remove all files from /home/user/mapa/mojimenik into /home/user/novi using command: "mkdir-p /home/user/novi && mv /home/user/mapa/mojimenik/* /home/user/novi"
    4. +
  4. Write all regular files containing a string "mama" into file "mama.txt", and all errors in file "napake.txt" by using: "find . -type f | grep mama 1> mama.txt 2> napake.txt".

Namen vaje

+

Naučite se uporabe nekaj BASH ukazov.

+

Naloga na hitro

+

Uporabljali boste BASH ukaze kot so: mv, grep, env in druge.

+

Navodila

+ +

    +
  1. Prijavite se v sistem. V domačem imeniku najdete imenik Mapa z 20 datotekami.
    2. +
  2. Preimenujete vse datoteke tako, da zamenjate minuse s podčrtaji z ukazom: "rename 's/-/_/' *".
    3. +
  3. Premaknite vse datoteke /home/user/mapa/mojimenik v /home/user/novi z ukazom: "mkdir-p /home/user/novi && mv /home/user/mapa/mojimenik/* /home/user/novi"
    4. +
  4. V datoteko "mama.txt" zapišite vse navadne datoteke v trenutnem imeniku, ki vsebujejo niz "mama", v datoteko "napake.txt" pa zapišite vse morebitne napake z ukazom: "find . -type f | grep mama 1> mama.txt 2> napake.txt".
    5. +
  5. Sledite vsebini /var/log/syslog za 5 sekund in v primeru, da se v syslogu pojavi niz "zmeda", izpišite "imam ga". Poleg tega med sledenjem syslog-u odštevajte od 5 do 1 z ukazom: "for i in 5 4 3 2 1; do echo $i; echo $(sed -n "$i p" /var/log/syslog | grep zmeda > /dev/null && echo "imam ga"); sleep 1; done".
    6. +
  6. Nastavite okoljsko spremenljivko TEST, da bo imela isto vrednost kot okoljska spremenljivka USER + število okoljskih spremenljivk, ki v imenu ali vrednosti ne vsebujejo besede TEST tako, da na koncu datoteke ~/.bashrc dodate: "export TEST=$USER" + "$(env | grep -v TEST | wc -l)"

+V domači mapi najdeš imenik {{file_rename_dirname}} z 20 datotekami. Preimenuj vse datoteke tako, da zamenjaš minuse s podčrtaji. + +

+Napiši najkrajši ukaz v bash, ki vse datoteke iz imenika {{mv_src_dir}} premakne v imenik {{mv_dst_dir}}. Ukaz spravi v /home/student/mv_ukaz. Pazite, da bodo ob testiranju v izvornem imeniku iste datoteke, kot so bile, ko je bila virtualka nova, ciljni imenik pa bo prazen. To pomeni, da boste verjetno morali po vsakem testiranju datoteke premakniti nazaj. Za krajšanje ukaza lahko izkoristite imeni imenikov. + +

+Napiši ukaz, ki s pomočjo ukaza grep v datoteko ~/mama.txt izpiše imena vseh navadnih (ne skritih) datotek v trenutnem imeniku, ki vsebujejo niz mama, v datoteko ~/napake.txt pa izpiše vse morebitne napake (npr. to, da so nekateri objekti v trenutnem imeniku dejansko imeniki ali napačne simbolične povezave). Ukaz spravite v datoteko /home/student/mama_ukaz. + +

+Napiši program (lahko v bash), ki bo pet sekund sledil vsebini /var/log/syslog. V primeru, da se v syslogu pojavi niz zmeda, naj program izpiše imam ga. Poleg tega naj program med sledenjem syslog-u odšteva od 5 do 1 (vsako sekundo naj se izpiše naslednja številka). Program naj bo v /home/student/syslog_ukaz.sh. + +

+Log into the system as student using vaje as your password. + +

+In your home folder you will find a directory called {{file_rename_dirname}} containing 20 files. Rename all files in that directory replacing all dashes with underscores + +

+Find the shortest command for copying all the files located in {{mv_src_dir}} into the folder {{mv_dst_dir}}. Create a shell script /home/student/mv_ukaz containing this command. Before running test_task.py, make sure {{mv_src_dir}} contains the same files as when you downloaded your virtual disk. This probably means that you will have to move the files back from {{mv_dst_dir}} to {{mv_src_dir}} after each test. + +

+Come up with a command or sequence of commands in bash which will, using grep, write the names all normal (not hidden) files which contain the string mama and are located in the working directory (pwd) into the file ~/mama.txt while writing errors such as files in current directory being folders or symbolic links in the file called napake.txt. Write this command to /home/student/mama_ukaz. + +

+Write a program (which may be a shell script) that will track the contents of /var/log/syslog for five seconds. Every time an entry containing the string zmeda appears in the syslog, the script should output imam ga. In addition, the script should count down from 5 to 1 with a one-second interval. Store the script in /home/student/syslog_ukaz.sh. + +

+Install the package cowsay and test it. 😊 + +

+Using the curl command count the number of occurences of the string images on the web page accessible from malishell at http://localhost/{{curl_fname}}. On simpleArbiterDhcpGW within the shell where you are running test_task.py, set the environment variable $images to this number. + +

+In the directory {{wc_dirname}} there is a file called count.txt.

Custom rdate

+

Short preview:

+ Set time on server using rdate. Write a program that converts 32-bit numbers into a readable time format.

+

Instructions:

+ 1. Downlaod Student.vdi (client) and SimpleArbiter.vdi (server) from the virtual machine images folder
+ 2. Use VirtualBox (or similar) to create two virtual machines, select the virtual disk images from the previous step as hard drives
+ 3. Run both virtual machines.
+ 4. Login on client user: root pass: kaboom and server user: tester pass: tester

+ + +

First part: update time using rdate.

+

+ 1. Find and remember your server IP address. (ifconfig)


+ 2. Install rdate with sudo apt-get install rdate
+ 3. On Student client use rdate to update the machine time rdate SERVER_IP

+ Note: It's NOT an error if the updated time does not match the correct time.
+

+

Second part: write a program that converts 32bit numbers into a readable time format.

+

+ You can write a program in Java or Python using your favourite text editor. +

+

Java

+

+ 1. We use nano guliver.java to create a new blank file
+ 2. Write a program that converts 32bit numbers into a readable time format.
+

+ 3. Press Ctrl+X, then Y and Enter to save the program
+ 4. In case you don't have java installed use sudo apt-get install openjdk-6-jdk
+
+ 5. To compile use javac bintodec3.java
+ 6. Run the created program with java guliver and input the server IP or name...
+
+

+

Python

+ 1. Use nano guliver.py to create a new empty python file.
+ 2. Write a program that converts 32bit numbers into a readable time format.
+
+ 3. Press Ctrl+X, then Y and Enter to save our program
+ 4. Run the created program with python guliver.py

+

+

Testing

+

+ 1. Use command ./run_test.py to run the tester
+
+ 2. Your username and password are the same as on ucilnica (npr.: "pz1234@student.uni-lj.si" in "geslo123").
+
+ 3. Name of the task should look like 09.predvaja.
+ 4. When prompted for file path insert your program path (example: if bintodec3.py is in the same folder as program run_test.py run with ./bintodec3.py).
+ 5. Then input your server IP address (SimpleArbiterRDate).
+ 6. If all goes well the program should give you an OK that means you've completed your task successfully. +

Custom rdate

+

Naloga na hitro:

+

+ Nastavi uro na strežniku s pomočjo rdate. Napiši program, ki pretvori 32-bitna števila v čas. +

+

Navodila:

+

+ 1. Z imenika s slikami virtualnih računalnikov povlecite sliki Student.vdi(klient) in SimpleArbiterRDate.vdi(strežnik).
+ 2. Z VirtualBoxom (ali podobnim) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte Student.vdi ter SimpleArbiterRDate.vdi.
+ 3. Zaženite oba navidezna računalnika.
+ 4. Na Student se prijavite z uporabnikom root in geslom kaboom + na SimpleArbiterRDate pa z uporabnikom tester in geslom tester. +

+ +

Prvi del naloge: posodobi uro računalnika s pomočjo rdate.

+

+ 1. Preverite in si zapišite IP naslov na SimpleArbiterRDate. (ifconfig)


+ 2. Z ukazom sudo apt-get install rdate namestimo program rdate.
+ 3. Na Student z pomočjo rdate posodobi uro računalnika. rdate IP_SIMPLE_ARBITER

+ Opozorilo: NI napaka, če se posodobljen čas ne ujema s pravilnim časom.
+

+

Drugi del naloge: napiši program, ki pretvori binarni zapis 32-bitnega števila v časovni format.

+

+ Nalogo lahko rešite v Javi ali v Pythonu. Prav tako pa lahko kodo pišete v poljubnem tekstovnem urejevalniku.

+

+

Java

+

+ 1. Z ukazom nano guliver.java ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
+ 2. Napišemo program za pretvarjanje 32-bitnega števila v čas
+ 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.
+ 4. Če je še nimamo, naložimo Javo sudo apt-get install openjdk-6-jdk

+ 5. Prevedemo program javac bintodec3.java
+ 6. Lahko ga še zaženemo ter preizkusimo java guliver.Na standardni vhod vnasemo IP naslov ali ime strežnika NTP strežnikom, ki nam pošlje 32 bitno število in pretvori v čas

+

+

Python

+

+ 1. Z ukazom nano guliver.py ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
+ 2. Napišemo program za pretvarjanje 32-bitnega števila v čas
+ 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.
+ 4. Program zaženemo z ukazom python guliver.py

+

+ +

Testiranje

+

+ 1. Lahko poženemo tester; z ukazom ./run_test.py
+
+ 2. Kot "Upor. Ime" in "Geslo" napišite vaše podatke učilnice. (npr.: "pz1234@student.uni-lj.si" in "geslo123")
+
+ 3. Kot ime naloge vpišite 09.predvaja.
+ 4. Ko vas program vpraša po poti programa vnesite vašo pot do programa za pretvarjanje. (npr.: če imate program bintodec3.py v isti mapi kot program run_test.py, vnesete: ./bintodec3.py)
+ 5. Povpraša tudi po IP naslovu SimpleArbiterjaRDate, vnesite.
+ 6. Če je šlo vse po sreči, program vrne OK vi pa ste opravili nalogo. +

Purpose of this exercise

+

How to perform live boot using a DHCP server.

+ + +

We need VirtualBox and the following 4 virtual +machines: +

+

+ +

Schematics of our subnet

+ slika-01 +

Our goal is to make BootableClient A get it's IP +through DHCP server and boot up using file +A, which is located on simpleArbiterGW,
If we run +BootableClient B machines, we would like it to retrieve it's IP +through DHCP server and boot from some live ISO which is also located on +SimpleArbiterGW. +

+ +

Setting up simpleArbiterGW

+

Download simpleArbiterGW.vdi +and then run VirtualBox. After the file is downloaded, choose the New +option in VirtualBoxu and set simpleArbiterGW in the Name +field.
Memory size, should be set accordingly (1gb will suffice). Then choose "Use an existing virtual hard drive file" and select simpleArbiterGW.vdi clicking Create.

+
+ slika-02 +

We start our virtual machines simpleArbiterGW using the +following login +credentials; username: "root", password: "kaboom".

+ At the start, the computer on NAt get's it's IP(in our case 10.0.2.15).
(to check this useifconfig) We now use this address and eth0 interface to access the internet.

+ slika-03 +

However, we would like this machine to have 2 +interfaces! One on NAT(we already have this one), and the other one on Internal Network,
throuh which we will communicate wiht the DHCP Server and other machines on our Internal Network.

+ We add a new interface, by turning off the virtual machine, +select our machine in VirtualBox and select +računalnik, ter v VirtualBoxu Settings -> Network
+ Adapter 1 is already set to NAT, we set Adapter +2 to +Internal Network

+ slika-04 +

So, now we have two network interfaces!
In VirtuaBox +we can define multiple Internal Networks, however, for our needs two +will suffice. We save the settings and restart simpleArbiterGW.

+ What we must do now, is to assign both interfaces IP addresses. We do this by setting theinterfacesfile + located at/etc/network.

+ slika-05 +

Eth0 was already handled by and integrated DHCP, so eth0 had been assigned an IP).
+ We have to set up the other network interface. If we don't know it's name, we find it out using ifconfig -a.

+ slika-06 +

We can conclude the interface names is set to Eth1. + Now we would like to assign an IP naslov to Eth1.
+ Ifconfig could be used, but rebooting the machine would reset the settings. Which is not ideal :)
+ So configuring /etc/network/interfaces would be a better idea.

+ Let's make up a random local network or a local area network or local area network address and assign it to eth1. +

+ slika-07 +

We save the config file. Our machine still has no IP on eth1 so we use the ifup eth1 command

+ slika-08
+

Now we use the ifconfig command, to see whether and ip is assigned to eth1 interface

+ slika-09 +

We can see the IP is set. Now let's set up the DHCP +Server!

+ +

Setting up DHCP Server

+

We download simpleArbiterDhcp.vdi and start VirtualBox. After the file had been dowloaded we select New in VirtualBoxu and unde rthe Name tag write DHCP Server.
We set the Memory size accordingly(1gb of memory should be sufficient). We also select "Use an existing virtual hard drive file" and select the simpleArbiterDhcp and press Create.

+
+ slika-10 +

We run DHCP Server virtual machine and login using "root" ad username and "kaboom" as password.

+

At first, our machine has no assigned IP, since none was set! Let+s configure it in /etc/network/interfaces.
But which interface should we configure? Using ifconfig -a command, we see it's eth0interface.
+ Again we select our IP address.

+ slika-11 +

We save the configuration file. Our computer still has no IP address assigned to eth0, so using ifdown eth0 and then ifup eth0we provide one.

+ slika-12 +

Now let us use ifconfig command, to check whether there is an IP assigned to interface eth0

+ slika-13 +

We got it! We install DHCP server using apt-get install isc-dhcp-server

+ slika-14 +

We see a bunch of errors. Why? Bacause, we have no internet access!
+ We need to specify the Gateway for our inteface. Our Gateway will be set as IP of our simpleArbiter virtual machine.
We do this using theroute add default gw 192.168.251.1 eth0 command

+ slika-15 +

Try pinging Google's DNS server at 8.8.8.8, to check if now have internet access.
+ We do this using the ping 8.8.8.8 command.

+ slika-16 +

Google's DNS server is responding. Great!
+ However, we still cannot run apt-get install isc-dhcp-server
+ Let's tempororly add another interface and set it to NAT, so we get internet access and install the DHCP server.

+ We add a new interface by turning off the virtual computer, in VirtualBox we select our virtual machine and then select Settings -> Network
+ Adapter 1 has already been set to Internal Network, we set Adapter 2 to NAT

+ slika-17 +

We run DHCP Server and in file/etc/network/interfaces at the end of the line add iface eth1 inet dhcp, then save the file and run ifup eth1.
+ Now we have access to the internet and can install our DHCP server with apt-get install isc-dhcp-server install command
+ slika-18
+

Let's see what's in/var/log/syslog, which is a file where our system information is stored in.

+ slika-19
+

Looks like we need to set up a DHCP server and specify where it should listen!
+ DHCP settings are stored in /etc/dhcp/dhcpd.conf. Let's set it!
+ First let's comment out option domain-name-servers to avoid having errors.

+ slika-20
+

Then we configure DHCP server, so it would serve IPs a a certain subnet. We add the following lines:

+ slika-21 +

(subnet) We set the subnet and the IP range, which the DHCP server should use, and which file it should serve.

Some PXEs are so unintelligent, that you should specify where they should get the files from and to do that you specify next-server
(IP from which it will be served from, in our case simpleArbiter), we also specify gateway, which, in our case is also simpleArbiter.

Since we would like, that in the case of BootableClient B another file to be served, we do it by defining a special host like this:
(host special) Under hardware ethernet we specifiy MAC address of our BootableClient B, we assign it a static ip and where the file live-ISO is located.

+

We save the settings and kill the process named dnsmasqusingkilall dnsmasq.

+ slika-22 +

We restart our DHCP server, to apply the new settings. This is done using service isc-dhcp-server restart
command. DHCP server is now ready! We supply BootableClientA and BootableClientB and test them!

+ + +

Setting up BootableClient A

+

We open VirtualBox and select New, for the +Name field we specify +BootableClient A and for the Hard drive we select Do not add a +virtual +hard drive (as we want diskless device),
and select Create. +We want the computer to be on Internal network so vse select our +Bootable Client +A and select
Settings->Network where we change Adapter +1 to Internal Network.

+ slika-23 +

We also want our computer to boot through the network, so +underBoot Ordertab select Network.
+ We save the setting by clicking OK

+ slika-24 +

We run our BootableClient-a A and it get's it's +IP(which is great), using the DHCP server and the simpleArbiter serves +it exactly the file we specified. A.0

+ slika-25 + + + +

Setting upBootableClient +B

+

We open virtual box and select New and under the Name tag write BootableClient B and under the Hard drivetab choose Do not add a virtual hard drive (since we want a diskless machine),
and then press the Create button, which will create a virtual machine. We want our machine to be connected to out Internal network so we select Bootable Client B and then select
Settings->Network and set the Adapter 1 to Internal Network.
+ Under MAC Address we specify the same MAC address that is specified in the (dhcpd.conf -> host special) file, since we want our machine to be an exception
and will be served a special file namedlive-ISO

+ slika-26 +

We want our machine to perform a netboot, so under the System

Boot Order tag specify only Network.
+ We save the setting by clicking the OK button

+ slika-27 +

We run our BootableClient-a A and it get's it's IP address using DHCP server and simpleArbiter serves it the file we selected called live-ISO

in pritisnemo na gump Create, da se nam ustvari navidezni računalnik. Želimo, da bo računalnik priklopljen na Internal network zato označimo naš Bootable Client B ter pritisnimo na
Settings->Network in prvi Adapter 1 spremenimo na Internal Network.
+ Poleg tega nastavimo še pod MAC Address takšen MAC naslov, kot ga imamo v nastavitvah DHCP strežnika (dhcpd.conf -> host special), saj želimo da bo ta naš računalnik izjema
in bo ob zagonu dobil drugo datoteko kot ostali in sicer live-ISO

Namen vaje

+

Kako narediti live boot z DHCP strežnikom.

+ + +

Potrebujemo program VirtualBox ter naslednje 4 navidezne računalnike: +

+

+ +

Skica našega podomrežja

+ slika-01 +

Naš cilj je, da računalnik BootableClient A preko DHCP strežnika pridobil IP naslov ter se zažene z datoteko A, ki se nahaja na simpleArbiterGW,
če pa zaženemo računalnik BootableClient B pa si želimo, da ta preko DHCP strežnika pridobi IP naslov ter se zažene z nekim live ISO, ki se prav tako nahaja na simpleArbiterGW. +

+ +

Postavitev simpleArbiterGW

+

Prenesemo simpleArbiterGW.vdi ter zaženemo VirtualBox. Ko je datoteka prenesena v VirtualBoxu izberemo New ter v polje Name vpišemo simpleArbiterGW.
Ustrezno nastavimo tudi Memory size (1gb pomnilnika nam bo zadostovalo). Spodaj izberemo še "Use an existing virtual hard drive file" ter izberemo naš simpleArbiterGW.vdi in pritisnimo Create.

+
+ slika-02 +

Nato zaženemo virtualni računalnik simpleArbiterGW ter se z uporabniškim imenom "root" ter geslom "kaboom" vpišemo v naš sistem.

+ Prvo računalnik od NAT-a, kateri je vgrajen v VirtualBox dobi nek naslov (v našem primeru 10.0.2.15).
(Da to preverimo uporabimo ukaz ifconfig) Preko tega IP naslova in vmesnika eth0 smo povezani v internet.

+ slika-03 +

Mi pa si želimo 2 omrežna vmesnika na tem računalniku! Enega bi radi imeli na NAT (tega že imamo) drugega pa na Internal Network,
preko katerega bomo komunicirali z DHCP Strežnikom ter ostalimi računalniki, ki bodo v našem Internal Network-u.

+ Nov omrežni vmesnik dodamo tako, da ugasnemo naš virtualni računalnik, ter v VirtualBoxu označimo naš virtualni računalnik in pritisnemo na Settings -> Network
+ Adapter 1 imamo že nastavljeno na NAT, Adapter 2 pa nastavimo na Internal Network

+ slika-04 +

Tako, zdaj imamo nastavljena 2 vmesnika!
V VirtualBoxu lahko definiramo več Internal Networkov (notranjih omrežij) a za naše potrebe bo to dovolj. Shranimo nastavitve ter ponovno poženimo naš simpleArbiterGW.

+ Zdaj moramo oba omrežna vmesnika nastaviti tako, da bosta imela nek naslov. Uredimo datoteko interfaces v imeniku + /etc/network.

+ slika-05 +

Za eth0 je poskrbel že DHCP strežnik, ki je vgrajen v VirtualBox (na eth0 je določil nek IP).
+ Mi moramo nastaviti še drugi mrežni vmesnik. Kako se imenuje iz glave ne vemo zato s pomočjo ukaza ifconfig -a pogledamo.

+ slika-06 +

Ugotovimo da je ime vmesnika eth1. + Zdaj bi rad na eth1 nastavil en IP naslov.
+ Lahko bi nastavil z ifconfig, a ko rebootaš računalnik se nastavitve ne ohranijo. To nebi radi!
+ Pojdimo raje skonfigurirat nastavitve v /etc/network/interfaces

+ Izmislimo si eno naključno lokalno omrežje oz naslov lokalnega omrežja ter nastavimo eth1. +

+ slika-07 +

Shranimo konfiguracijsko datoteko. Moj računalnik še nima IP-ja na eth1 zato uporabim ukaz ifup eth1

+ slika-08
+

Sedaj uporabimo ukaz ifconfig, da vidimo če imamo slučajno ip na vmesniku eth1

+ slika-09 +

Vidim, da ip imam. Super! Gremo postavit DHCP Server!

+ +

Postavitev DHCP Server

+

Prenesemo simpleArbiterDhcp.vdi ter zaženemo VirtualBox. Ko je datoteka prenesena v VirtualBoxu izberemo New ter v polje Name vpišemo DHCP Server.
Ustrezno nastavimo tudi Memory size (1gb pomnilnika nam bo zadostovalo). Spodaj izberemo še "Use an existing virtual hard drive file" ter izberemo naš simpleArbiterDhcp in pritisnimo Create.
Ustrezno nastavimo tudi nastavitve mreže iz NAT na Internal Network

+
+ slika-10 +

Nato zaženemo virtualni računalnik DHCP Server ter se z uporabniškim imenom "root" ter geslom "kaboom" vpišemo v naš sistem.

+

Sprva naš računalnik nima nobenega ip-ja saj mu ga nismo nastavili! Pojdimo skonfigurirat nastavitve v /etc/network/interfaces.
Ampak kateri vmesnik sploh konfiguriramo? Z ukazom ifconfig -a ugotovimo da je to eth0.
+ Spet si izberemo nek svoj statičen ip naslov.

+ slika-11 +

Shranimo konfiguracijsko datoteko. Moj računalnik še nima IP-ja na eth0 zato uporabim ukaz ifdown eth0 ter nato še ifup eth0

+ slika-12 +

Sedaj uporabimo ukaz ifconfig, da vidimo če imamo slučajno ip na vmesniku eth0

+ slika-13 +

Hura imamo! Namestimo naš DHCP strežnik z ukazom apt-get install isc-dhcp-server

+ slika-14 +

Vidimo, da dobimo cel kup napak. Ampak zakaj? Zato, ker nimamo dostopa do interneta!
+ Vmesniku eth0 moramo seveda povedati Gateway. Naš Gateway bo seveda IP našega simpleArbiter navideznega računalnika.
To naredimo s pomočjo ukaza route add default gw 192.168.251.1 eth0

+ slika-15 +

Probajmo ping-ati Googlov DNS strežnik, da ugotovimo če imamo sedaj internet.
+ To naredimo z ukazom ping 8.8.8.8.

+ slika-16 +

Googlov DNS strežnik se odziva, super!
+ Ampak apt-get install isc-dhcp-server še vedno ne moremo naložiti.
+ Začasno dodajmo še en mrežni vmesnik ter ga nastavimo na NAT, nato bomo dobili dostop do interneta ter lahko namestimo naš DHCP strežnik.

+ Nov omrežni vmesnik dodamo tako, da ugasnemo naš virtualni računalnik, ter v VirtualBoxu označimo naš virtualni računalnik in pritisnemo na Settings -> Network
+ Adapter 1 imamo že nastavljeno na Internal Network, Adapter 2 pa nastavimo na NAT

+ slika-17 +

Zaženemo naš DHCP Server in v /etc/network/interfaces začasno na koncu dodamo vrstico iface eth1 inet dhcp,datoteko shranimo ter poženemo ukaz ifup eth1.
+ Sedaj imamo dostop do interneta in lahko namestimo naš DHCP strežnik z ukazom apt-get install isc-dhcp-server install
+ slika-18
+

Poglejmo kaj je v /var/log/syslog, to je datoteka kamor se shranjujejo sporočila kaj se dogaja v našem sistemu

+ slika-19
+

Očitno moramo nastaviti dhcp strežnik ter mu povedati tudi kam naj posluša!
+ Za nastavitve DHCP strežnika imamo /etc/dhcp/dhcpd.conf. Nastavimo jo!
+ Prvo zakomentiramo option domain-name-servers zaradi tega da nebo napak da jih ne najde.

+ slika-20
+

Nato skonfiguriramo dhcp strežnik, da bo serviral ip-je na nekem podomrežju. Dodamo naslednje zapise:

+ slika-21 +

(subnet) Nastavimo podomrežje ter območje naslovov od koder naj jih DHCP strežnik dodeli, katero datoteko naj servira,
poleg tega so eni PXE tako neumni, da če jim ti serviraš filename nevejo iz katerega serverja ga dobim, zato napišem še next-server
(ip od koder serviram, v našem primeru simpleArbiter), nastavim tudi gateway kateri je v našem primeru tudi simpleArbiter.

Ker bi radi, da v primeru zagona navideznega računalnika BootableClient B serviramo drugo datoteko, to naredimo tako da definiramo nek dodaten host na sledeč način:
(host special) Pod hardware ethernet zapišemo MAC naslov našega BootableClient B katerega bo imel, dodelimo mu nek statičen ip naslov ter povemo še iz kje se naj datoteka live-ISO zažene.

+

Spremembe shranimo, ter ubijemo proces z imenom dnsmasq z ukazom kilall dnsmasq.

+ slika-22 +

Sledi restart našega DHCP strežnika, da bo deloval z novimi nastavitvami, to naredimo z ukazom service isc-dhcp-server restart
DHCP Strežnik je pripravljen! Pripravimo BootableClientA ter BootableClientB ter testirajmo!

+ + +

Postavitev BootableClient A

+

Odpremo VirtualBox ter izberemo New in pod Name napišemo BootableClient A ter pod Hard drive izberemo Do not add a virtual hard drive (saj si želimo računalnik brez diska),
in pritisnemo na gump Create, da se nam ustvari navidezni računalnik. Želimo, da bo računalnik priklopljen na Internal network zato označimo naš Bootable Client A ter pritisnimo na
Settings->Network in prvi Adapter 1 spremenimo na Internal Network.

+ slika-23 +

Želimo še, da se računalnik boot-a preko mreže, zato to nastavimo pod zavihkom System

tako, da pod Boot Order obkljukamo samo Network.
+ Nastavitve shranimo z pritiskom na gumb OK

+ slika-24 +

Poženemo našega BootableClient-a A in odličnoo, dobi ip naslov s pomočjo DHCP strežnika in simpleArbiter mu servira točno to datoteko katero si želimo A.0

+ slika-25 + + + +

Postavitev BootableClient B

+

Odpremo VirtualBox ter izberemo New in pod Name napišemo BootableClient B ter pod Hard drive izberemo Do not add a virtual hard drive (saj si želimo računalnik brez diska),
in pritisnemo na gump Create, da se nam ustvari navidezni računalnik. Želimo, da bo računalnik priklopljen na Internal network zato označimo naš Bootable Client B ter pritisnimo na
Settings->Network in prvi Adapter 1 spremenimo na Internal Network.
+ Poleg tega nastavimo še pod MAC Address takšen MAC naslov, kot ga imamo v nastavitvah DHCP strežnika (dhcpd.conf -> host special), saj želimo da bo ta naš računalnik izjema
in bo ob zagonu dobil drugo datoteko kot ostali in sicer live-ISO

+ slika-26 +

Želimo še, da se računalnik boot-a preko mreže, zato to nastavimo pod zavihkom System

tako, da pod Boot Order obkljukamo samo Network.
+ Nastavitve shranimo z pritiskom na gumb OK

+ slika-27 +

Poženemo našega BootableClient-a A in odličnoo, dobi ip naslov s pomočjo DHCP strežnika in simpleArbiter mu servira točno to datoteko katero si želimo live-ISO

+ slika-28 +

Postavitev TFTP strežnika in zagonskih datotek

+ +

Na SimpleArbiter namestimo TFTP strežnik z ukazom apt-get install tftpd-hpa in spremenimo IP v "/etc/default/tftpd-hpa" pod TFTP_ADDRES na "192.168.251.1". +
Nato z ukazom apt-get install syslinux namestimo syslinux in skopiramo zagonsko datoteko iz "/usr/lib/syslinux/pxelinux.0" na "/srv/tftp/A.0.
Namestimo še NFS server z ukazom "apt-get install nfs-kernel-server" in v "/etc/exports" dodamo lokacijo mape, kjer se nahaja naša zagonska datoteka A.0, ter omogočimo branje ("/srv/tftp * (ro)"). +
V imeniku /srv/tftp ustvarimo mapo "pxelinux.cfg" in v njej ustvarimo datoteko z imenom default. Vanjo vpišemo : +

Purpose of the exercise

+

How to setup a LDAP Server, to add entries to a LDAP Server, and to change users' rights to be able to add entries and change the attributes of entries.

+ +

How To

+ +
    +
  1. Create two virtual machines, SimpleArbiterDhcpGWLDAP(simpleArbiterDhcpGWLDAP.vdi) and LDAPServer(student-LDAPServer.vdi). +
    No img
    2. +
    +
  2. Change the network settings to both virtual machines. SimpleArbiterDhcpGWLDAP: Adapter 1 is set to "NAT" for internet access and + adapter 2 to "internal network" for local network. LDAPServer: Adapter 1 set to "internal network" sot that it is in the same internal network as SimpleArbiterDhcpGWLDAP. +
    No img +
    No img +
    No img
    3. +
    +
  3. In SimpleArbiterDhcpGWLDAP log in as user "tester", in LDAPServer log in as user "root", run the command "apt-get update" to update the list of packages and + open up another terminal by pressing "ALT+F2" and log in as user "student".
    4. +
    +
  4. In LDAPServer run the command "apt-get install slapd ldap-utils" to install these packages which are the LDAP server and tools to access and manage the LDAP server. +
    During the LDAP server installation you'll have to provide the password for the user "admin", the administrator of the server and confirm the password chosen.
    5. +
    +
  5. Configure the LDAP server by choosing the appropriate domain name and other configuration parameters. Execute the commmand "dpkg-reconfigure slapd". +

    No img +
    No img +
    No img +
    No img +
    No img +
    a) If you will configure the "slapd" again don't forget to remove the old database "rm -rf /var/backups/unknown-2.4.44+dfsg-2.ldapdb".
    6. +
    +
  6. Now that the LDAP server is configured for use, try to open a third console and log in as user "student" and execute the command "ldapsearch -D cn=admin,dc=ceres-20,dc=kpov, + dc=lusy,dc=fri,dc=uni-lj,dc=si -W -b dc=ceres-20,dc=kpov,dc=lusy,dc=fri,dc=uni-lj,dc=si", which will show the entries in the server. +
    Because you will be using a lot the domain name to access the LDAP server you can set the environment variable "D", which will allow for quicker typing of commands. +
    "export D=dc=ceres-20,dc=kpov,dc=lusy,dc=fri,dc=uni-lj,dc=si" +
    "ldapsearch -D cn=admin,$D -wvaje -b $D"
    7. +
    +
  7. Create the file(LDIF format) "users.ldif" which will contain the objects(users) that we want to add to the LDAP server database. +
    No img +
    Execute the following command to add users to the LDAP server: +
    "ldapadd -D cn=admin,$D -wvaje -f users.ldif" +
    Add password to the users added to the LDAP server: +
    "ldappasswd -D cn=admin,$D -wvaje -sj2531e cn=ninavidmar,ou=users,$D" +
    "ldappasswd -D cn=admin,$D -wvaje -scTyRM0 cn=natalijaribnikar39,ou=users,$D" +
    Execute command "ldapsearch -D cn=natalijaribnikar39,ou=users,$D -wcTyRM0 -b $D" to bind to the LDAP server with the newly added user "natalijaribnikar39" and to see the entries currently in the LDAP server. +
    No img
    8. +
    +
  8. In order to change the users' rights settings, which allows a user to add entries to the directory and change values of attributes of entries in the directory you need to create an additional file acl.ldif: +
    To see which backend database is used and other settings related to the users' rights execute command "ldapsearch -Y EXTERNAL -H ldapi:/// -b cn=config" as root user in the system, which does not need the user authentication to the LDAP server. +
    No img +
    The settings in the acl.ldif file: +
    No img +
    Now to change users' rights run the command "ldapmodify -Y EXTERNAL -H ldapi:/// -f acl.ldif" as user "root" in the system.
    9. +
    +
  9. The user "natalijaribnikar39" has the right to add or change objects in the LDAP server. +
    Now try to bind to the LDAP server using "natalijaribnikar39" user's credentials and add a new user to the server directory. +
    "ldapadd -D cn=natalijaribnikar39,ou=users,$D -wcTyRM0 -f newuser.ldif"
    10. +
    +
  10. Now to test your result go to the SimpleArbiterDhcpGWLDAP virtual machine and run "./test_task.py" to run the test and see your score. +

MOCK ENTRANCE EXAM - HOWTO

 + +

1) POSTAVITEV VIRTUALK

+ +Najprej prenesi obe sliki za virtualki iz sistema kpov-judge, 2. naloga. Če se sliki ne naložita takoj, malo počakaj in osveži stran. +Ustvari novo virtualko imenovano "Student", tip je načeloma "Linux" ter verzija "Ubuntu (64-bit)" - lahko pa je tudi karkoli drugega. Določi ustrezno količino pomnilnika, ki bo na voljo napravi, izberi možnost rabe obstoječe slike navidezne naprave ter izberi prenešeno datoteko "student-entrance.vdi". Klikni ustvari.
ni slike
+Prejšnji postopek ponovi še za "SimpleArbiter", "Linux", "Ubuntu (64-bit)", "simplearbiter.vdi".
ni slike
+ +

2) OMREŽNE NASTAVITVE VIRTUALK

+ +V navodilih naloge lahko vidimo, da morata biti obe virtualki povezani v internet ter povezani med seboj prek nekega notranjega omrežja. +Na "SimpleArbiter" nastavimo pod Settings->Network->Adapter 1; Enable network adapter "check", Attached to: NAT. ->Adapter 2; Enable network adapter "check", Atached to: Internal Network.
ni slike ni slike
+Na "Student" je postopek nastavitve enak kot na "SimpleArbiter".
ni slike ni slike
+ +OPOMBA: Pozoren je treba biti, da sta oba vmesnika, ki sta povezana na notranje omrežje (Internal Nerwork) povezana preko istega omrežja, npr. "intnet". + +

3) ZAGON VIRTUALK IN POSOTPEK NALOGE

+ +SA - SimpleArbiter +STUD - Student + +Najprej zaženemo obe vritualki, to storimo s klikom na gumb start. +Na SA se prijavimo z uporabniškim imenom "tester" ter geslom "tester" + +

3.1) POSKRBIMO ZA MREŽO

+ +

3.1.1) SPREMEMGA GESLA ZA ROOT

+ +Z uporabo ukaza /sbin/ifconfig preverimo, ali so vmesniki pravilno nastavljeni. Kaj kmalu ugotovimo, da je na SA aktiven samo en vmesnik. Za nastavljanje omesnikov moramo najprej postati "root", torej uporabnik, ki ima pooblastila za urejanje sistemskih nastavitev. +Najprej ponovno zaženemo virtualko: "sudo reboot", potrdimo z geslom "tester". +V GRUB meniju (zagonski meni) nato pritisnemo tipko "e", ki omogoča spreminjanje ukazov pred zagonom. Vrstico "53d ro" spremenimo v "53d rw init=/bin/bash". Pritisnemo "F10" in sprožimo zagon naprave. +Sedaj lahko kot super uporabnik zamenjaš geslo za root, to storiš z ukazom "passwd", sistem te nato vpraša za novo geslo, po vnosu pa še za potrditev gesla. Geslo je uspešno spremenjeno, spremembe pa je potrebno še shraniti na disk, to storiš z ukazom "mount -o remount,ro /", izvedi še ukaz "sync", da se podatki res zapišejo na disk. Sedaj lahko virtualko ponovno zaženeš kar iz Machine->Reset. + +

3.1.2) NASTAVIMO OMREŽNE VMESNIKE

+ +V virtualko SA se sedaj prijavimo kot uporabnik "root" ter s spremenjenim geslom "karsinastavil". +Sedaj spremenimo nastavitve omrežnih vmesnikov tako, da bodo naslovi ustrezali tistim v navodilih. Izvedemo ukaz "ifconfig enp0s8 10.0.2.129 netmask 255.255.255.128 up" +Preklopimo na virtualko STUD (uporabnik "root", geslo "kaboom") ter izvedemo podoben ukaz "ifconfig enp0s8 10.0.2.X netmassk 255.255.255.128", kjer je X podatek iz navodil naloge. +Notranje omrežje testiramo tako, da pošljemo ping iz SA do STUD z ukazom "ping NASLOV", kjer je NASLOV omrežni naslov na STUD, ki je povezan na notranje omrežje (nastavitev iz prejšnjega koraka). +SUPER, omrežje deluje, gremo naprej. Če ne deluje, preveri pravilnost naslovov na SA in STUD, bodi pozoren na dolžino maske ter na morebitne zatipke. + +

3.2) "ZLONAMERNI" PROGRAM

+ +V navodilih naloge je podano ime programa, ki naj bi ob svojem zagonu pokvaril nastavitve omrežnih vmesnikov na STUD. Z ukazom "ps xa | grep IMEPROGRAMA" preverimo, če se program izvaja. V izpisu ugotovimo, da se najvrjetneje ne izvaja, zato lahko zadevo ignoriramo. Če bi se program izvajal, bi bilo potrebno ukrepati ter ga na nek način izbrisati oz. mu onemogočiti spreminjanje omrežnih vmesnikov (najlažje bi bilo uporabiti ukaz "kill", ki kot argument prejme PID (prvi stolpec prejšnjega izpisa) ter konča izvajanje tega procesa). Več o ukazu "kill" si preberi na spletu! + +

3.3) PREVAJANJE PROGRAMA

+ +Najprej si odpremo novo konzolo na STUD "alt+F2" ter se prijavimo kot "student" z geslom "vaje". +Z ukazom "ls" preverimo vsebino domačega direktorija uporabnika student. Izpisati bi se morala datoteka, ki jo imamo podano v navodilih. To datoteko moramo najprej odpreti z ukazom "vim IMEDATOTEKE". Datoteko moramo sedaj popraviti tako, da odstranimo odvečne črke, to storimo tako, da izvedemo ukaz ":%s/[QXW]*//g", sedaj izvedemo še ":syn on" in si obarvamo kodo. Izhod iz urejevalnika ":wq". +Ta program sedaj z ukazom "gcc IMEPREVEDENEGAPROGRAMA IMEDATOTEKE" prevedemo v nov program, kjer je IMEPREVEDENEGAPROGRAMA izhodni program, katerega ime je prav tako podano v navodilih, IMEDATOTEKE pa ime pravkar popravljene datoteke. + +

3.4) SKRIPTA

+ +Sedaj bomo napisali nov program/skripto, uporabimo urejevalnik nano; "nano IMESKRIPTE", kjer je IMESKRIPTE podano v navodilih naloge. +V skripto zapišemo sledeče;
+
+----BREZ TE VRSTICE-------
+
+#!/bin/bash
+
+echo -n $SPREMENLJIVKA | /home/student/IMEPREVEDENEGAPROGRAMA "argument" 2> /home/student/IMEDATOTEKE_STDERR | grep "ma" > /home/student/IMEDATOTEKE_STDOUT
+
+----BREZ TE VRSTICE-------
+
+Datoteko shranimo "ctrl+x" ter potrdimo z "y" in enter. +Datoteko sedaj spremenimo v program "chmod +x IMESKRIPTE" + +

4) TESTIRANJE NALOGE

+ +Preklopimo nazaj na SA ter odpremo novo konzolo "alt+F2", vpišemo se kot uporabnik "tester" z geslom "tester" in poženemo program "./test_task.py" +Izpolnimo vsa polja; URL "https://kpov.fri.uni-lj.si/kpov_judge/tasks", vpišemo svoje uporabniško ime in geslo (za dostop do KPOV-JUDGE preko učilnice) npr. "jn1234@student.uni-lj.si geslozaucilnico", ime naloge "02-preparation-mock_entrance_exam". Sedaj se pojavijo še vaši vhodni in izhodni podatki za nalogo, preverite, če so pravilni; datoteka z izhodom, IP naslov SA, ime spremenljivke, ime "zlonamernega" programa, datoteka z napakami ter neko naljučno seme itd. +Če program vrne 10 OK je naloga uspešno opravljena, sicer pa vrne število doseženih točk ter napako. + + + diff --git a/tasks/mock_entrance_exam/task.py b/tasks/mock_entrance_exam/task.py new file mode 100644 index 0000000..ad51c2a --- /dev/null +++ b/tasks/mock_entrance_exam/task.py @@ -0,0 +1,313 @@ +# TODO: +# - check if everything is filled in (computers, params, preparation) +# - improve scoring +# - test +# - switch to a real SSH/SFTP client to properly handle filenames + +instructions = { + 'si': '''\ +

NAT VLC:

 +

Explanation:


+ Set up a computer so that it forwards all packets meant for a certain address, to another computer.

+

Instructions:

+

1. Create two VMs. SimpleArbiter using the disk simpleArbiter and NATServer.

+ You can get the disks at polz.si/media/uploads/kpov/virtualke. As for the NATServer VM, you can use any disk you want like base-student-desktop-2014. +
+

2. NATServer should have two network interfaces, one should connect to the simpleArbiter VM and the other to the internet.

+ Adapter 1 should be NAT and adapter 2 should be Internal Network.
+ Simple Arbiter must be connected to the Internal Network. +
+ slika-1 +

3.On NATServer use ifconfig or /etc/network/interfaces to configure the network interfaces you created in virtualbox.

+ + -vim /etc/network/interfaces
+ -Set it up like this:
+ auto eth1
+ iface eth1 inet static
+ NETMASK 255.255.0.0 # Specify based on your requirement
+ IPADDR 192.168.2.1 # Gateway of the LAN
+ NETWORK 192.168.0.0 # Optional
+ ADDRESS 192.168.0.0
+ -ifdown eth1
+ -ifup eth1 +
+slika-2 +

4. Configure SimpleArbiter so that it uses NATServer as the default gateway.

+ +

5. Set up DNS (etc/resolv.conf) on NATServer.

+ vim /etc/resolv.conf + nameserver 203.145.184.13 # Primary DNS Server provided by the ISP
+ nameserver 202.56.250.5 # Secondary DNS Server provided by the ISP
+ Than we set up the host:
+ vim /etc/hosts
+ Replace the first line with:
+ 127.0.0.1 nat localhost.localdomain localhost
+ +

6. Enable IP forwarding on NATServerju (should be run as root).

+ echo 1 > /proc/sys/net/ipv4/ip_forward + +

7. Set up NAT on NATServer using iptables.

+ + apt-get install iptables
+ iptables -F
+ ptables -t nat -F
+ iptables -t mangle -F
+ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
+ iptables -A FORWARD -i eth1 -j ACCEPT

+ + service iptables restart + +

8. Use vlc on simpleArbiter to watch the video over your network.

NAT VLC:

 +

Naloga na hitro:


+ Nastavi računalnik tako, da bo vse pakete za določene naslove prepošiljal na drug računalnik, vzpostavi NAT.

+

Navodila:

+

1. Postavi dva navidezna računalnika. SimpleArbiter z diskom simpleArbiter ter NATServer.

+ Virtualke dobiš na (polz.si/media/uploads/kpov/virtualke). Za NATServer lahko uporabiš base-student-desktop-2014. +
+

2. Postavi NAT server tako, da ima dva omrežna vmesnika. Z enim naj bo povezan na simpleArbiter, z drugim pa na internet.

+ (settings-Network) Adapter 1 nastavimo na NAT (omrežje), adapter 2 pa na InternalNetwork (lokalno).
+ Simple Arbiter nastavimo na InternalNetwork(lokalno). +
+ slika-1 +

3.Na NATServer z ukazom ifconfig in z datoteko /etc/network/interfaces skonfiguriraj omrežne vmesnike
+ tako, da bo en povezan v WAN (internet) in en vmesnik na LAN (simpleArbiter).

+ + -vim /etc/network/interfaces
+ -dopišemo:
+ auto eth1
+ iface eth1 inet static
+ NETMASK 255.255.0.0 # Specify based on your requirement
+ IPADDR 192.168.2.1 # Gateway of the LAN
+ NETWORK 192.168.0.0 # Optional
+ ADDRESS 192.168.0.0
+ -ifdown eth1
+ -ifup eth1 +
+slika-2 +

4. SimpleArbiter skofiguriraj tako, da bo privzeti prehod uporabljal NATServer.

+ Nastavi gateway, da ima IP od NATServerja.
+ route add -net IP netmask MASK default gw IP dev eth0
+ +

5. Nastavi DNS (etc/resolv.conf) na NATServerju.

+ vim /etc/resolv.conf + nameserver 203.145.184.13 # Primary DNS Server provided by the ISP
+ nameserver 202.56.250.5 # Secondary DNS Server provided by the ISP
+ Nato nastavimo še host:
+ vim /etc/hosts
+ Prvo vrstico zamenjamo z:
+ 127.0.0.1 nat localhost.localdomain localhost
+ +

6. Omogoči posredovanje IP naslovov na NATServerju.

+ echo 1 > /proc/sys/net/ipv4/ip_forward + +

7. Nastavi NAT z uporabo paketa iptables na NATServerju.

+ + apt-get install iptables
+ iptables -F
+ ptables -t nat -F
+ iptables -t mangle -F
+ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
+ iptables -A FORWARD -i eth1 -j ACCEPT

+ + service iptables restart + +

8. Na simpleArbiter z vlc preberi naslov, na katerem si lahko ogledaš kratek filmček.

+ + apt-get install vlc-nox
+ Nastavitev naslova:
+ Open Media > OpenNetwork ....
+ + + +

OpenVPN and SMB task:

 +

Quick task:


+ Connect to VPN with OpenVPN. Enable access to files through NFS and copy them through SMB.

+

Instructions:


+ 1. From Directory with images of virtual computers drag twice the picture SimpleArbiterVPN and VPNClient.
+ 2. With VirtualBox (or other programs for virtual computers) create two virtual computers and give them VPNCLient.vdi and SimpleArbiterVPN.vdi as disk for storage.
+ 3. On both set two network interface(NAT and Internal) and run them.
+ 4. On both VM login with username root and password kaboom .

+

First part: Set up OpenVPN on SimpleArbiterVPN and VPNClient.

+

Settings on the server:

+ 1. Download packages uml-utilities -> to adjust the virtual network interfaces and packet (openvpn). example: sudo apt-get install openvpn
+ 2. The new virtual network interface create with tunctl and specify IP with sudo ifconfig tap0 10.P.Q.R netmask 255.255.255.0
+ 3. Then generirate common key (you will share that key with client) with the command: openvpn --genkey --secret vpnkljuc.key
+ 4. On server set the configuration file tap0.conf, which should contain (split by lines) "dev tap0","proto tcp-server", "secret vpnkljuc.key"
+ 5. Run openvpn with openvpn --config /some_directory/somewhere/tap0.conf
+

Settings on the client:

+1., 2. steps are the same as the settings on the server
+3. Create configuration file tap0.conf, which should contain (split by lines) "remote IP_OF_YOUR_VPN_SERVR", "dev tap0", "proto tcp-client", "secret vpnkljuc.key"
+4. On OpenVPN server connect to openvpn --config /some_directory/somewhere/tap0.conf
+

+ +

Second part: Access to imenika /home/test/IME_IMENIKA over NFS

+

Client settings:

+ 1. Using "sudo apt-get install nfs-kernel-server" we install nfs service
+ 2. Create a directory /home/test/IME_IMENIKA
+ 3. To /etc/exports add line /home/test/bla IP_client + 4. Use sudo exportfs -a to save + 5. Restart service using "sudo service nfs-kernel-server start" +

Client settings:

+ 1. Instal client for nfs with command "sudo apt-get install nfs-common"
+ 2. Create mounting directory "sudo mkdir -p /mnt/nfs/home/test" and mount servers file "sudo mount IP_SERVER:/home/test"
+ 3. For automatic mounting we add previous commands to /etc/fstab
+ +

OpenVPN in SMB vaja:

+

Naloga na hitro:


+ Vzpostavi VPN povezavo z pomočjo OpenVPN. Omogoči dostop do datotek prek NFS in skopiraj datoteke prek SMB.

+

Navodila:


+ 1. Iz imenika s slikami virtualnih računalnikov dvakrat povlecite sliki SimpleArbiterVPN ter VPNClient.
+ 2. Z VirtualBoxom (ali ostalim programom za virtualne računalnike) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte VPNCLient.vdi ter SimpleArbiterVPN.vdi.
+ 3. Na obeh nastavite dva omrežna vmesnika (NAT in Internal) in jih zaženite.
+ 4. Na oba VM-a se prijavite z uporabnikom root in geslom kaboom .

+

Prvi del naloge: Nastavi OpenVPN na SimpleArbiterVPN in VPNClient.

+

Nastavitve na strežniku:

+ 1. Prenesite pakete uml-utilities -> za nastavljanje navideznih omrežnih vmesnikov in paket (openvpn). Npr: sudo apt-get install openvpn
+ 2. Nov navidezni omrežni vmesnik kreirate z tunctl in mu podate IP z sudo ifconfig tap0 10.P.Q.R netmask 255.255.255.0
+ 3. Nato generirate skupen ključ(ta ključ boste delili z klientom) z ukazom: openvpn --genkey --secret vpnkljuc.key
+ 4. Na strežniku še nastavite konfiguracijsko datoteko tap0.conf, ki naj vsebuje (ločeno po vrsticah) "dev tap0","proto tcp-server", "secret vpnkljuc.key"
+ 5. Zaženete openvpn z openvpn --config /some_directory/somewhere/tap0.conf
+

Nastavitve na klientu:

+1., 2. koraka sta ista kot pri nastavitvah na strežniku
+3. Kreirajte konfiguracijsko datoteko tap0.conf, ki naj vsebuje (ločeno po vrsticah) "remote IP_VAŠEGA_VPN_SERVERJA", "dev tap0", "proto tcp-client", "secret vpnkljuc.key"
+4. Na OpenVPN strežnik se povežete z openvpn --config /some_directory/somewhere/tap0.conf
+

+

Drugi del naloge: Dostop prek NFS do imenika /home/test/IME_IMENIKA

+

Nastavitve na strežniku:

+ 1. Z ukazom "sudo apt-get install nfs-kernel-server" namestimo nfs program
+ 2. Uredimo mapo exports "sudo nano /etc/exports" in kreiramo direktorij /home/test/IME_IMENIKA
+ 3. V datoteko exports dodamo /home/test/bla IP_klienta + 4. Share shranimo z sudo exportfs -a + 5. NFS strežnik štartamo z "sudo service nfs-kernel-server start" +

Nastavitve na klientu:

+ 1. Z ukazom "sudo apt-get install nfs-common" namestimo programček nfs-common, da lahko kasneje pripnemo share
+ 2. Na klientu moramo urediti še mount tega direktorija: "sudo mkdir -p /mnt/nfs/home/test" in "sudo mount IP_SERVERJA:/home/test"
+ 3. Za avtomatski mount ob ponovnem zagonu, dodamo prejšnje ukaze v datoteko /etc/fstab
+ +

Radius mysql:

 +

Quick how to:


+ Setup the OpenRadius server and add users. Use MySql as the database.

+

Instructions:

 +
    +
  1. Create two virtual machines - SimpleArbiter (use the simpleArbiterDhcp.vdi disk) and RadiusServer. Discs for virtual machines are located on polz.si/media/uploads/kpov/virtualke.
    2. +
  2. Create another two virtual machines using the disks VPNCLient.vdi and SimpleArbiterVPN.vdi.
    3. +
  3. Setup both VMs so that they use two network adapters - NAT and Internal network.
    4. +
  4. Login with the username student and password student on both VMs.
    5. +
+ +

Part one: Setup OpenRadius.

+
    +
  1. Install OpenRadius on the RadiusServer VM (configuration files are: /etc/openradius/configuration and /etc/openradius/behaviour)
    2. +
  2. Add a user and assign him a shared secret. This should be configured in the /etc/openradius/configuration file. (More info: http://sites.e-advies.nl/openradius/doc-using-openradius.html )
    3. +
  3. Create a connection from SimpleArbiter to RadiusServer using the secret you configured.
    4. +
+

Part two: Install and setup a MySQL database on RadiusServer

 +
    +
  1. OpenRadius can use the module RadSQL to store users in database.
    2. +
  2. Setup a MySQL server: sudo apt-get install mysql-server.
    3. +
  3. Connect to the MySQL server: mysql -u root -p.
    4. +
  4. Create a database: CREATE DATABASE . Create a table users with columns username and password.

Radius mysql:

 +

Naloga na hitro:


+ Postaviti je treba RADIUS strežnik in podatkovno bazo.
+ Za RADIUS strežnik uporabite FreeRADIUS, za podatkovno bazo pa MySQL. +

+

Navodila:


+ 1. Ustvarite dva navidezna računalnika z imenom SimpleArbiter in RadiusServer.
+ Za SimpleArbiter uporabite simpleArbiterDhcp, za RadiusServer pa lahko uporabite poljubno virtualko.
+ ( virtualke dobiš na polz.si/media/uploads/kpov/virtualke)
+ 2. Z VirtualBoxom (ali ostalim programom za virtualne računalnike) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte simpleArbiterDhcp.vdi ter base-student-console-2014.vdi.
+ 3. Na obeh nastavite dva omrežna vmesnika (NAT in Internal) in jih zaženite.
+ 4. Na oba VM-a se prijavite z uporabnikom student in geslom vaje .

+

Prvi del naloge: Postavi OpenRadius.

+ 1. Namesti FreeRadius na virtualki RadiusServer z ukazom "sudo apt-get install freeradius".
+ ( pomembni sta dve konfiguracijski datoteki /etc/openradius/configuration in /etc/openradius/behaviour
+ 2. Dodaj uporabnika in mu dodaj skupno skrivnost v /etc/openradius/configuration datoteko (več o dodajanju lahko izveš na: "http://sites.e-advies.nl/openradius/doc-using-openradius.html"
+ 3. Nato se z to skrivnostjo povežete iz SimpleArbiter na RadiusServer
+ + Namestimo freeradius z ukazom apt-get install freeradius-mysql + V datoteku /etc/freeradius/client.conf spremenimo skrivnost (secret) + Nato pa v datoteki /etc/freeradius/users dodamo uporabnika + + +

Drugi del naloge: Namestitev in vzpostavitev baze MySQL na RadiusServer

+ 1. Pri OpenRadius-u imamo modul RadSQL, s katerim lahko vzpostavimo hranjenje uporabnikov v bazi
+ 2. Namestimo MySQL server z ukazom "sudo apt-get install mysql-server"
+ 3. VNato se prijavimo v Mysql server z ukazom mysql -u root -p
+ 4. Bazo ustvarimo z ukazom primer: + CREATE DATABASE kwhbRgJY; + GRANT ALL ON kwhbRgJY.* To MajaNovak80@localhost IDENTIFIED BY "y06gmo2Z"; + + + diff --git a/tasks/radius_mysql_pam/task.py b/tasks/radius_mysql_pam/task.py new file mode 100644 index 0000000..5051bb4 --- /dev/null +++ b/tasks/radius_mysql_pam/task.py @@ -0,0 +1,212 @@ +# kpov_util should be imported by add_assignment.py + +instructions = { + 'si': '''\ +

Purpose of the assignment

+Learn how to setup network interfaces in most modern Linux distributions (NetworkManager). +

+

+

Quick instructions

+Set a static IP in NetworkManager, set a static IP and DNS server in /etc/network/interfaces. You'll get both IP's when you execute script run_test.py. +

+

+

Instructions

+
    +
  1. From the directory with images of virtual computers, download the following:
    maliNetworkManager, maliBrezNetworkManager, SimpleArbiterDhcp.
    2. + +
  2. Set the network for virtual computers, so that SimpleArbiterDhcp's 1. nework interface is connected to the same network, as the only network interface for maliNetworkManager and maliBrezNetworkManager,
    + SimpleArbiterDhcp's 2. network interface will be connected to a NAT or a physical network, where the address and route (gateway) to the internet is obtained via DHCP.
    3. + +
  3. Start SimpleArbiterDhcp. Sign in as user "tester" with password "SedemKrogovPekla".
    4. +
  4. +slika-04
    +Use command 
    ping 193.2.1.66
    to check if SimpleArbiterDhcp is connected to internet. If you get ping reply, you're connected to the internet. Cancel the ping with combination CTRL+C.
    + If SimpleArbiterDhcp doesn't have internet access, change the network settings in Virtual box for 1. and 2. network interface, then restart the virtual computer. + +
    5. +
  5. Run the script run_test.py.
    6. + +
  6. Enter "03.predvaja" as assignment name.
    7. + +
  7. Read the maliNetworkManager's static IP . Leave SimpleArbiterDhcp running in the background until you have setup the maliNetworkManager.
    8. + +
  8. Start maliNetworkManager.
    9. + +
  9. +Sign in the GUI(graphical user interface) using username "student" and password "vaje".
    10. +
  10. ikona network manager
    +Right click on the icon for network settings.
    + +
  11. +Menu NetworkManager
    +Choose "Edit Connections"
    12. + +
  12. +Menu NetworkManager
    +Click "Edit"
    13. + +
  13. +Menu NetworkManager
    +In tab "IPv4" change the "Method" to "Manual". Click "Add". Set the SimpleArbiterDhcp's static IP as static IP A.
    +Add Arnes DNS: 193.2.1.66 to DNS servers. +
    14. +
  14. Click "Save"
    15. + +
  15. Switch to SimpleArbiterDhcp. Click "Enter" or "OK".
    16. + +
  16. Read maliBrezNetworkManager's IP . Click "OK". Read the DNS server's address .
    17. + +
  17. Switch to maliBrezNetworkManager. Switch to first console using combination CTRL+ALT+F1. Sign in as root (su) with password "kaboom".
    18. + +
  18. Open the file /etc/network/interfaces. Edit the settings according to the information you got on SimpleArbiter. Entry for network interface should look something like this:
    +
    +allow-hotplug eth0
+iface eth0 inet static
+    10.0.1.2
+    netmask 255.255.255.128
+    dns-nameservers 10.0.1.5
+
    +
    19. + +
  19. Save the settings. Use the command 
    reboot
    to restart maliBrezNetworkManager. On boot the NetworkManager reads which network interfaces are configured in /etc/network/interfaces. After that NetworkManager doesn't manage these interfaces anymore.
    20. + + +Press OK on SimpleArbiterDhcp. If all went ok, you have completed this assignment. +

Set up two virtual machines, set MOTD. Connect using ssh.

+ +

How To

+ +
    +
  1. Create two virtual machines, Student(student-console) and Test(SimpleArbiterDhcpGw)
    no img
    2. +
  2. Change the network settings to both virtual machines. SimpleArbiterDhcpGw: Adapter 1 set it to NAT for internet access, Adapter 2 to internal network for local network. + Student: Adapter1 set it to "internal-network" so it is in the same domestic network as SimpleArbiterDhcpGw.

  3. Login on Student
    no img
    4. +
  4. On Student(student-console) create a new user (with "adduser username", as the task demands of you ( eg. marjankoral19 ), with a custom password.
    no img
    5. +
  5. In Student(student-console) open interfaces file ( nano /etc/network/interfaces ) and set the IP
    +

    How to use the nano text editor

    +

    + 1.) Open the nano editor with the command nano, which is followed by the path and name of the file. Example: nano /etc/myfile. If the file doesn't exist, the file will be created by the editor.
    + 2.) To move in the editor, we use the arrow keys, backspace is used for deleting.
    + 3.) To save a file press the combination of keys ctrl + O.
    + 4.) To exit the editor press the combination of keys ctrl + X. The editor will ask you, if you really want to exit, you can answer with y (yes ) or with n ( no ).
    + 5.) To cut a line press the combination of keys ctrl + K.
    + 6.) To paste a line press the combination of keys ctrl + U.
    + 7.) To search over a document press the combination of keys ctrl + W and then enter the search string. +

    6. +
  6. We can check which interface belongs to which adapter in Virtual-box with MAC address. Run ifconfig command and compare the HWaddr value with the value in the Virtual-box ( settings => network => adapter => Mac address )
    no imgno img
    7. +
  7. Then edit the /etc/motd (eg. with nano editor like this: "nano /etc/motd"), file with the specified string. (eg. "Not for Human consumption" )
    no img
    8. +
  8. For testing, login with the test user into Test(SimpleArbiterDhcpGw)
    no img
    9. +
  9. Then connect to the Student with ssh, using the user marjankoral19 - ssh marjankoral@ip.
    no img
    10. +
  10. If the login was successful, the Message of the day should apear.
    11. +
  11. To run Kpov_judge, login onto SimpleArbiterDhcpGw, find and run the file test_task.py ( with ./test_task.py as all other scripts )
    no img
    12. +
  12. A window appears as we can see on the image above, then press Enter, enter your username ( eg. dr6784@student.uni-lj.si ), password, task name (eg. 01-preparation-set_motd), enter the string we should get in motd, enter the username and password of a user on Student(student-console)(eg. marjankoral19), the IP of Student(student-console), and after a brief moment we should get the result. no img

Kako se ustvari uporabnik? Kako se popravi datoteka? Kako se s pomočjo ssh +povežemo na drug racunalnik? Kako ugotovimo IP naslov računalnika?

+ +

Naloga na hitro

+

Postavi 2 navidezna računalnika, nastavi MOTD. Poveži se preko ssh.

+ +

Podrobna navodila

+ +
    +
  1. Ustvari dva navidezna računalnika, računalnik Student(student-console) ter računalnik Test(SimpleArbiterDhcpGw)
    ni slike
    2. +
  2. Spremeni omrežne nastavitve obema navideznima računalnikoma, SimpleArbiterDhcpGw: Adapter 1 na NAT za dostop do interneta, Adapter 2 na "internal network" za lokalno omrežje, + Student: Adapter1 na internal-network, da je v enakem omrežju kot SimpleArbiterDhcpGw.

    3. +
  3. Prijavi se na računalniku Student.
    ni slike
    4. +
  4. Na računalniku Student(student-console) ustvari novega uporabnika (z ukazom "adduser imeuporabnika"), kot to od tebe zahteva naloga (npr. marjankoral19), geslo določi sam.
    ni slike
    5. +
  5. Računalnik Student, odpri datoteko interfaces ( nano /etc/network/interfaces ), ter nastavi IP.
    ni slike
    6. +

    Kako se uporablja nano urejavalnika besedila:

    +

    + 1.) Urejvalnik Nano odpremo z ukazom nano, kateremu sledi ime datoteke. Primer: nano /etc/mojadatoteka. Če datoteka ne obstaja jo bo ustvaril urejevalnik.
    + 2.) Po urejevalniku se premikamo s smernimi puščicami, brišemo s tipko backspace.
    + 3.) Za shranjevanje dokumenta pritisnemo kombinacijo tipk ctrl + O
    + 4.) Za izhod iz urejevalnika pritisnemo kombinacijo tipk ctrl + X. Pri tem nas urejevalnik upraša, če želimo shraniti spremembe. Odgovorimo z y (yes, ja ) ali z n ( no, ne ).
    + 5.) Za izrez vrstice uporabimo kombinacijo tipk ctrl + K.
    + 6.) Za lepljenje vrstice se uporablja kombinacija tipk ctrl + U.
    + 7.) Za iskanje po besedilu uporabimo kombinacijo tipk ctrl + W, nakar vnesemo iskani niz in pritisnemo tipko enter. +


    +
  6. Kateri vmesnik (npr. eth0) spada pod kateri adapter (npr. Adapter1 ), lahko preverimo s strojnimi naslovi. Na računalniku zaženemo ukaz ifconfig, pogledamo HWaddr vrednost ter jo primerjamo z vrednostjo v Virtual-boxu (nastavitve => omrežja => adapter => MAC address
    ni slikeni slike
    7. +
  7. Nato spremeni datoteko /etc/motd (z urejevalnikom nano, primer uporabe: "nano /etc/motd"), ter zamenjaj niz z ustreznim nizom kot to od tebe zahteva naloga ( npr. "Not for Human consumption" )
    + ni slike
    8. +
  8. Za testiranje se s testnim uporabniškim imenom prijavi na prvem računalniku. (SimpleArbiterDhcpGw)
    ni slike
    9. +
  9. Nato se preko ssh poveži na računalnik Student z uporabniškim imenom marjankoral19 - ssh marjankoral19@ip.
    ni slike
    10. +
  10. Po uspešni prijavi se bi moralo izpisati motd sporočilo.
    11. +
  11. Kpov_judge poženemo tako da se prijavimo na računalniku SimpleArbiterDhcpGw, najdemo datoteko test_task.py ter jo poženemo ( z ./test_task.py kot se poganjajo vse skripte )
    ni slike
    12. +
  12. Pojavi se nam okno kot ga vidimo zgoraj, nato pa pritisnemo tipko Enter, vnesemo svoje uporabniško ime ( npr. dr6784@student.uni-lj.si ), geslo, ime naloge (npr. 01-preparation-set_motd), vnesemo niz ki bi se nam moral prikazati, vnesemo ime uporabnika na računalniku Student (npr. marjankoral19) ter njegovo geslo, ip računalnika študent, nato pa po kratkem premoru dobimo rezultat. ni slike

KPOV Judge 7 (SMB NFS)

+

V tej vaji postavimo na linux-u strežnik za nudenje datotek prek mreže in strežnik za SMB, s katerim lahko na Windows sistemih postavimo datoteko v skupno rabo. Pazi da bo simpleArbiterDhcpGW imel NFS pravico pisanja po imeniku!

+

Virtualni računalniki

+
    +
  • simpleArbiterDhcpGW
    • +
  • student-fileserver
    • +
+

simpleArbiterDhcpGW

+

Naj ima 2 omrežna vmesnika, prvi naj bo preko NAT povezan na svetovni splet, drugi vmesnik pa naj vsebuje interno povezavo znotraj virtualnih sistemov na tvojem računalniku “intnet”.

+

student-fileserver

+

Naj ima 1 omrežni vmesnik, povezan na interno omrežje “intnet”.

+

Parametri

+
+ Parametri +

Parametri za reševanje naloge

+
+

Tokrat imamo tri parametre. “Imenovani” dir, smb-share, smb-server.

+

Oziroma iz slike so to:

+
    +
  • dir = TeNVU74X
    • +
  • smb-share = aurora-85
    • +
  • smb-server = melete-04
    • +
+

Postopek

+

Ko zaženemo simpleArbiterDhcpGW in student-fileserver se najprej prijavimo v oba sistema. Nato pa na student-fileserver poženemo

+ 
apt-get update && apt-get install nfs-kernel-server samba
+

Nastavitve NFS

+

V datoteki /etc/exports dodamo sledečo vrtstico: /srv/nfs/[dir] [IP simpleArbiterDhcpGW](rw).

Datoteko shranimo in znova poženemo NFS strežnik.

+ 
service nfs-kernel-server restart
+

Ustvarimo imenik, ki smo ga malce prej navedli v nastavitvah NFS. In nato omogočimo vsem pisanje po tem imeniku.

+
+ 
+mkdir /srv/nfs/[dir]
+chmod oug+w /srv/nfs/[dir]
+
+
+

Nastavitve SMB

+

Vse nastavitvene datoteke SMB se nahajajo v imeniku: /etc/samba. Zanima pa nas datoteka smb.conf.

+ 
# Datoteka smb.conf
+    [global]
+
+    workgroup = WORKGROUP
+    netbios name = [smb-server] # Nadomestek DNS, ki si ga je izmislil Microsoft
+
+    # Malce nižje pod vrstico =========== Share Definitions =========== dodamo svoje nastavitve
+
+    [[smb-share]] # Primer iz slike: [aurora-85]
+    path = /srv/nfs/[dir]
+    read only = no
+    guest ok = yes
+    browseable = yes
+

Ko popravimo to datoteko restartamo SMB in NetBios s spodnjima ukazoma.

+ 
service smbd restart
+service nmbd restart
+

Quick instructions

+

+ Set up three virtual computers, SimpleArbiter with the disk image + simpleArbiterDhcp, SNMPServer and SNMPClient. Write a program + called upminutes. This program should output the uptime of the + computer in minutes. Set it up on SNMPClient in the home directory + of the user test with the password test. +

+

+ Make sure that the SNMP server reports it's uptime in seconds + over SNMP under NET-SNMP-EXTEND-MIB::nsExtendOutput2Table. +

+

+ Write a script called beri.sh that reads the value from the + OID 1.3.6.1.4.1.8072.1.3.2.4.1.2 on SNMPServer. Set it up on + SNMPClient in the home directory of the user test. +

      + agentAddress udp:161,udp6:[::1]:161       +
      3. +
    +
    4. +
  4. + Add a group (community) of computers we deem to be worthy of + accessing all data. This group will be called students = again edit + snmpd.conf file. +
      +
    1. + rocommunity students 0.0.0.0/0 +
      2. +
    2. + write correct network address = command ifconfig -a +

Summary

+ +
    +
  1. Set up a virtual machine
    2. +
  2. Install VLC
    3. +
  3. Create RTP video stream
    4. +
  4. Make sure the stream is accessible from the internet
    5. +
+ +

Instructions

+ +
    +
  1. +

    Set up a virtual machine

    +

    Use disk simpleArbiter. You can get it here.

    +
    2. + +
  2. +

    Install VLC

    +

    + In file /etc/apt/sources.list replace wheezy with + testing or if missing, add rows: +

    +

    + + deb http://ftp.at.debian.org/debian wheezy main contrib non-free
    + deb-src http://ftp.at.debian.org/debian wheezy main contrib non-free +     +

    + slika-01 +

    + Check for updates and install VLC with the following commands: +

    +

    + + apt-get update
    + apt-get install vlc +     +

    +
    3. + +
  3. +

    Create a new stream

    + +

    + Open VLC. In Media menu select Stream. +

    + menu +

    + Here we choose stream source. This can be a file, a network stream or a capture device.
    + For this excercise, add one or more video file by clicking Add ... Continue with a click on button Stream. +

    + stream source +

    + We must also choose the stream destination. For this excercise, choose RTP/MPEG Transport Stream and click Add. + You can configure multiple destinations simultaneously. +

    +

    + Configure destination settings. Enter address and stream name. +

    + stream destination +

    + Next, we can set transcoding, encapsulation, audio and video codecs and also subtitles. When you finish, click Save and Next. +

    + stream settings +

    + In the last step, it is important to check option Stream all elementary streams. + In the text area, we can see the string that can be used to run the stream from a command line. + This is useful if you want to run stream from a computer without graphic interface. +

    + +
    4. + +
  4. +

    Open stream

    +

    + We can now play the stream from another device using VLC. +

    + play stream +

Naloga na hitro

+ +
    +
  1. Postavi navidezni računalnik
    2. +
  2. Naloži VLC
    3. +
  3. Ustvari RTP video tok
    4. +
  4. Poskrbi, da bo tok dostopen na internetu
    5. +
+ +

Navodila

+ +
    +
  1. +

    Postavi navidezni računalnik

    +

    Uporabi disk simpleArbiter. Dobiš ga lahko tu.

    +
    2. + +
  2. +

    Naloži VLC

    +

    + V /etc/apt/sources.list v spodnjih vrsticah zamenjaj wheezy z + testing oziroma dodaj vrstice če niso napisane: +

    +

    + + deb http://ftp.at.debian.org/debian wheezy main contrib non-free
    + deb-src http://ftp.at.debian.org/debian wheezy main contrib non-free +     +

    + slika-01 +

    + Poglej za posodobitve in nato naloži VLC z naslednjimi ukazi: +

    +

    + + apt-get update
    + apt-get install vlc +     +

    +
    3. + +
  3. +

    Ustvari nov tok

    + +

    + Odpri VLC. V meniju Media izberi Stream. +

    + Meni +

    + V oknu "Open Media" izberemo vir toka. Ta je lahko datoteka, že obstoječ omrežni tok ali pa snemalne naprave.
    + Za namen te naloge lahko z klikom na gumb Add ... dodamo eno ali več video datotek. Nadaljujemo z klikom na Stream. +

    + Vir toka +

    + Določiti moramo tudi destinacijo toka. Za to nalogo izberemo RTP/MPEG Transport Stream in kliknemo Add. + Možno je nastaviti več destinacij hkrati. +

    +

    + Nato izpolnimo nastavitve destinacije z naslovom in imenom toka. +

    + Destinacija toka +

    + V naslednjem koraku lahko nastavimo kodiranje, enkapsulacijo, avdio in video nastavitve ter podnapise. +

    + Nastavitve Toka +

    + V zadnjem koraku je pomembno obkljukati možnost Stream all elementary streams. + V spodnjem tekstovnem polju dobimo niz, ki ga lahko uporabimo za zagon toka iz ukazne vrstice. +

    + +
    4. + +
  4. +

    Odpri tok

    +

    + Na drugem računalniku lahko ustvarjen video tok predvajamo z VLC. +
