+ 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 za reševanje naloge

+
+

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

+

Oziroma iz slike so to:

+ +

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.
