-
1. - Postavi DHCP strežnik -
  1. - - apt-get update - -
  2. - - apt-get install isc-dhcp-server -
  3. - Strežnik se ne bo zagnal (javi Starting ISC DHCP server: dhcpdcheck syslog for diagnostics. ... failed!), potrebno je popraviti 3 datoteke: -
    - - V /etc/network/interfaces določi statičen IP vmesnika eth1, na njem bo tekel DHCP strežnik, - npr.: -
      - 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
      -
      -
    - - V /etc/default/isc-dhcp-server: -
      - INTERFACES="eth1" -
      -
    - - V /etc/dhcp/dhcpd.conf določi lastnosti podomrežja, - npr.: -
      - authoritative;
      - default-lease-time 600;
      - max-lease-time 7200;
      -
      - subnet 192.168.1.0 netmask 255.255.255.0 {

      - fixed-address 192.168.1.180;
      - }
      - }
      -
      -
    -
  -
2. - Postavi NFS strežnik -
  1. - - apt-get install nfs-kernel-server -
  2. - Določi pravila v /etc/exports, npr.: -
    - #pravice za SimpleArbiterDhcp
    - /srv/nfs/ERLbbBrT 192.168.1.180(rw,sync,insecure)
    - /srv/nfs/ERLbbBrT 192.168.1.0/24(ro,sync,insecure)
    -
    -
  3. Spremeni lastnika mape in datotek v njej: - - chown student /srv/nfs/ERLbbBrT - - ter podobno za datoteke v deljeni mapi. Lastnik naj ne bo root. -
  4. - Poženi ukaz - exportfs -rv" - za izvoz datotečnih sistemov -
    In nato še - - service nfs-kernel-server restart - -
    -
  -
3. - Postavi SMB strežnik -
  1. - - apt-get install samba -
  2. - Ustvari mapo urania-03 ter določi lastnika in pravice: -
    - mkdir /home/urania-03
    - chown -R root:users /home/urania-03/
    - chmod -R ug+rwx,o+rx+w /home/urania-03
    -
    -
  3. -
    Uredi nastavitve v /etc/samba/smb.conf:
    -
    - [global]
    - workgroup = users

    -
    - Z ukazom - - useradd USERNAME --shell /bin/false - - ustvariš uporabnika z onemogočenim računom in brez domačega direktorija, npr.: -

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 = TeNVU84X
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.
