Linux DHCP question

[wabob]

I know ifconfig shows my PCs network address, but is there a shell command so I can release / renew my PCs DHCP address?

service network restart"

Or, since you have ifconfig, you could...

ifconfig down
ifconfig up

I use Mandrake (mostly), so thedaver's suggestion is what I would use.

man pump:

pump is a daemon that manages network interfaces that are controlled by either the DHCP or BOOTP protocol.

       While pump may be started manually, it is normally started automatically by ifup(8) for devices configured via BOOTP or DHCP.

       If pump is managing an interface, you can run it again to query the status of that interface.  For example,
           pump -i eth0 --status
       will print the current status of device eth0.

I have SUSE Linux 10.0 and could not get any of those to work (probably will work for other Linux distributions).
But thanks anyways.

I did a little reading and found out how to do it.
I logged in as root and entered the following:

ifdown eth0
ifup eth0

That released and renewed my DHCP address for my PC.

Experience is a tough teacher.
The test comes first, the lesson comes later...
