eth0 help!

[canobeeens]

Hello folks,
I'm running RedHat 7.2 on a Dell laptop. I do not use the ethernet card when at home, but I do use it at work. When I boot into Linux at work, the laptop is docked, so Kudzu pops up and says my hardware config has changed. I tell it not to remove the old config. That's worked fine before, but today, no ethernet card. I checked under /etc/sysconfig/network-scripts/ifcfg-eth0 and the file is setup properly. The Hardware Browser under the KDE control Panel sees the NIC. Again under the Control Panel, in Network configuration, I (foolishly) deleted my NIC. Now when I try to add it again, I'm told it cannot initialize the device. When i try an ifconfig, lo is displayed. Anyone know a remedy? This is what I get for using gui tools HAHA.

Thanks,
Brian

open a terminal, su to root, and run ifconfig -a
if the ethernet device is not there,
cat /proc/pci
see if the card is there.

You do not mention if this is a standard pci nic or if it is a pcmcia nic

if this is a pcmcia device, did cardmgr start? -- can cardmgr see the device?

perhaps it was just a DHCP failure ... we had a weekend reconfig of the network were I work, and when all the laptop users tried to login, they failed miserably .. something about their hostnames were removed from the domain ... *grin* on the dhcp server .... (I'm sure NT services won't be making that mistake again any time soon... our *President* uses a laptop...)

Lorithar,
Thanks for replying. It is a 3com PCI Ethernet card. ifconfig -a shows only "lo". when I tried cat /proc/pci , i was able to see the NIC. It's definitely not a DHCP issue, because I gave myself a static IP address. It seems as if the system can see that the NIC is there, but can't initialize it. I know it works, because I dual boot w/Win2k, and it works fine there...
Ack! Could Kudzu be what is messing with this?

Is the module still loading?

[canobeeens]

How do I tell if the module is loading?

The "lsmod" command will return a list of loaded modules.
