+ Quick guide +

+ 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. +

+
1. + Set up a DHCP server +
  1. + + apt-get update + +
  2. + + apt-get install isc-dhcp-server + +
  3. + The server will not start (error + + Starting ISC DHCP server: dhcpdcheck syslog for diagnostics. ... failed!) + , configure 3 files: +
    - + In /etc/network/interfaces set static IP for eth1 on which the DHCP server will be running, + e.g.: +
      + auto eth1
      + iface eth1 inet static
      + address 192.168.1.10
      + netmask 255.255.255.0
      + network 192.168.1.0
      + broadcast 192.168.1.255
      +
      +
    - + In /etc/default/isc-dhcp-server: +
      + INTERFACES="eth1" +
      +
    - + In /etc/dhcp/dhcpd.conf configure the subnet properties, + e.g.: +
      + authoritative;
      + default-lease-time 600;
      + max-lease-time 7200;
      +
      + subnet 192.168.1.0 netmask 255.255.255.0 {
      + range 192.168.1.100 192.168.1.200;
      + option routers 192.168.1.10;
      + option domain-name-servers 193.2.1.66, 8.8.4.4;
      +
      + host SimpleArbiter {
      + hardware ethernet 08:00:27:A2:FB:B4;
      + fixed-address 192.168.1.180;
      + }
      + }
      +
      +
    +
  +
2. + Set up a NFS server +
  1. + apt-get install nfs-kernel-server +
  2. + Determine the rules in /etc/exports, e.g.: +
    + #privileges for SimpleArbiterDhcp
    + /srv/nfs/ERLbbBrT 192.168.1.180(rw,sync,insecure)
    + /srv/nfs/ERLbbBrT 192.168.1.0/24(ro,sync,insecure)
    +
    +
  3. + Change the owner of the directory and files in it: + + chown student /srv/nfs/ERLbbBrT + + and similarly for all the files in shared directory. The owner should not be root. +
  4. + Run command + exportfs -rv + to export file systems +
    After that run + + services nfs-kernel-server restart + +
    +
  +
3. + Set up SMB server +
  1. + + apt-get install samba + +
  2. + Create directory urania-03 and set owner and privileges: +
    + mkdir /home/student/urania-03
    + chown -R root:users /home/urania-03/
    + chmod -R ug+rwx,o+rx+w /home/urania-03
    +
    +
  3. + Edit configurations in /etc/samba/smb.conf, add at the bottom of document, e.g.: +
    + [global]
    + workgroup = users
    + server string = zarptica-32
    + dns proxy = no
    + log file = /var/log/samba/log.%m

    + force group = users + create mask = 0660
    + directory mask = 0771
    + writable = yes
    +
    +
  4. + Restart Samba: + + service samba restart + +
  5. +
    + Test the syntax of smb.conf file with command + + testparam + +
    +
  6. + Add users: +
    + In order to define passwords for Samba users they have to exist on a local system, too. +
    + Use command + + useradd USERNAME --shell /bin/false + + to create user with a disabled account and without home directory, e.g: +
    + useradd tester --shell /bin/false +
    +
    +
    + Define Samba password for your user: +
    + smbpasswd -a tester +
    +
    + Add the user to your group. +
    + Open /etc/group file and add group and users: + + users:x:1002:tester + +
    +
    +
  7. Restart Samba. +

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 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

Testiranje

Sedaj samo še testiranje :) Za to pa na simpleArbiterDhcpGW poženi testno skripto.
