- Quick guide
- </h2>
- <p>
- Set up two virtual computers - SimpleArbiterDhcp and FileServer.
- </p>
- <p>
- 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.
- </p>
- <p>
- SimpleArbiterDhcp should have write access to /srv/nfs/ERLbbBrT over NFS.

- <p>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!</p>

- <li>simpleArbiterDhcpGW</li>
- <li>student-fileserver</li>
- </ul>
- <h3>simpleArbiterDhcpGW</h3>
- <p>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 “<i>intnet</i>”.</p>
- <h3>student-fileserver</h3>
- <p>Naj ima 1 omrežni vmesnik, povezan na interno omrežje “<i>intnet</i>”.</p>
