eth0 interface fails

Hello all;

Whenever I boot my Red Hat 7.2, eth0 hangs for around thirty seconds and then gives me "determining IP" something "for eth0...FAILED". This is getting on my nerves and I want to connect it to the rest of my network. I've got a DEC 21040 (most 21*40 ethernet) card, and I've installed linuxconf, if that will help anyone help me. And please help me!

What is your network setup? Your error is typical of the network card setup for DHCP but no DHCP server found.

New problem.

Interface eth0 doesn't even seem to exist anymore. Grr.

Whenever I type "ifconfig eth0 up", it will say that there is no such device. Likewise, whenever I type "ifconfig up eth0", it says that the hostname is bad.

What am I, just bugged out?

Typically your network is set up when you install. You will have come accross a screen that allowed you to either specify your IP address or choose DHCP. The majority of cable/high speed internet providers use DHCP, as well as dial up (you recieve a new IP everytime you connect). If you want to check if you are using DHCP then run 'ps aux' and if you are you should see a line like:
root       305  0.0  0.0  1356  188 ?        S    Feb06   0:00 /usr/sbin/dhcpcd eth0

Try running as root in command line:


Answer all questions correctly (hostname is your machine) and make sure you have all the necessary information (primary and secondary DNS IPs, domain name, DHCP server name if needed, and DHCP server IP if needed).

For RedHat, it might be config-redhat-network but I'm not 100% on that. A RedHat user will most certainly correct me if I'm wrong.
