Changing linux network settings

[NikPreviousAcct]

Uh... anybody got any idea about how to set the computer name, release/renew the IP, and set the workgroup name in linux, via commandline?

My router says that it sees the PC connected, but Linux doesn't get an IP. The /etc/sysconfig/network/ifcfg-(MAC address) file is set up for DHCP, too.

Hell I don't even need command line, necessarily. I just can't get this damn thing online! Anyone got ANY pointers? At all??

Which distro?

I believe the command to use dhcp (won't work over reboots) is something along the lines of: dhcpcd eth0
