can't get eth0 as device, have lo though

[mad-eth0]

I'm trying to connect my Fresh RH7.3/KDE to connect to my DHCP server. I've got the lo device running loopback 127.0.0.1, and that's fine.

But I need to get eth0 device working and if I type in this command:

ifconfig eth0 192.168.123.254 netmask 255.255.255.0

It gives me this:

SIOCSIFADDR: No such device
eth0: unknown interface: No such device
SIOCSIFNETMASK: No such device

I have the etc/hosts set with localhost and the IP of my dhcp appliance; /etc/sysconfig/network set to yes; /etc/sysconfig/network-scripts/ifcfg-eth0 is set to eth0, dhcp, yes. And I've rebooted. I have no tools like linuxconfig or redhat-config-network (have 'setup', didn't work though), I guess in 7.3 they are gone. I don't even have the Network Configuration option in the main KDE menu, even though the RH7.3 docs say it's there. So I have to do this all by hand. And none of the steps in my 2 o'reilly linux books work (Running v3 and Admin Guide v2).

What now?

probably u'r modules did'nt get loaded. check thru lsmod whether the appropriate mosule for the card has been loaded.

u can always download linuxconf utility and install it. I think it is very useful for the general management of the system.

SCHIBY! I loaded the tulip.o and now I have eth0! YEE-HAW! I can even ping my DHCP! Holy ****...Konq works too! It takes forever to load google though. Oh well. Thanks again!
