+ 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>

+ <li>
+ In /etc/network/interfaces set static IP for eth1 on which the DHCP server will be running,

+ <li>
+ In /etc/dhcp/dhcpd.conf configure the subnet properties,
