dhcp

I use static ip's for home, but when I bring laptop to work, it is dhcp. I have changed some settings in /etc/conf.d/net to use dhcp, but eth0 won't start.

Is there someway to make the network look at the dhcp server? I'm not really sure what to do to get it to work. I've read a lot of posts, but none seem to have the answer.

Stupid question, but, are you sure you're running a DHCP server at home?

Have you installed and configured dhcpd or do you have a broadband router that provides a dhcp server?

Never mind my prior stupid reply. I didn't read your post carefully enough.

Perhaps your workplace uses some form of authorisation - probably by MAC address. You might want to talk to your IT/Networks guy and ask him.

My university does MAC authorisation, preventing you from getting an IP via DHCP until you've registered your MAC address. When you register, they make you update Windows with security fixes, and virus scan the machine - I guess this is all to prevent security breaches on the much less secure internal network of uni.

Nope, no mac address stuff. (I was able to use suse yast when it was installed once to automatically do it).
I tried dhcpcd -n but this didn't work. I end up with nothing (in fact, what /var/log/messages ends up saying is that it timed out waiting for a valid dhcp server response).

How does it know which dhcp server to use? Does it need to know?

Not sure if this will help you or not, but type dhcpcd eth0 as root and see if it works for you then. After a few long days of searching I found that to be the reason dhcp wasn't working for me. After typing that, I was issued an ipaddress and the world was once again within my grasp.
