Network help reqd, pls

[master_b]

Have just installed Knoppix 3.4 to my hard drive.

Can't access internet.

Had same problem when booting from Live CD but solved by replugging network cables.

System is router/modem to ethernet switch to 3 PC's.

How do I activate/deactivate eth0 in Knoppix/Debian? Other distros (ie Fedora Core 1) have a GUI.

By the way, my mobo has an onboard Realtek Gigabit ethernet connection, with which, from other posts, some people apparently have problems.

Thanks in advance

sudo netcardconfig

Oh and I think it's also a menu option w/ a GUI!
