(3) To edit the Ethernet/bus interface, contact your network administrator to insert
appropriate settings. “Activate device when computer starts” and “Allow all users
to enable and disable the device” are optional. If you do not choose to activate the
Ethernet at boot time, run ‘ifup eth0 <IP address>’ in the command line to bring
up the network every time when you restart the system. If you have a DHCP
server installed, you don’t need to key in any IP address.
