eth0 "not present" according to Redhat 9

briankb713 · 01-23-2005, 10:38 PM

Recently, my NICs stopped responding. I decided it best to reconfigure the system because my shorewall router was having some trouble. However, when I deleted everything from the RedHat 9 Network GUI, restarted and then reconfigured eth0, the GUI gave the error "delaying activation because the device does not seem to be present." Well, this is quite confusing because the device is hardwired onto the motherboard. I then tried my other NICs which are PCI cards and got the same error. Any ideas what may cause this error? Also, I thought it might be good to have linux redetect through kudzu, but I am a newbie still and not sure how to force this.

Any and all help is so appreciate! I keep finding one thing after another!

Sincerely,

Brian

What is the output of

Code:

lspci

Remember, this must be done as root.

To get Redhat to redetect a nic, you edit the file /etc/sysconfig/hwconf and remove the section which looks like this. Then you can run the command: kudzu or reboot for the hardware to get redetected.

Code:

-
class: NETWORK
bus: PCI
detached: 0
device: eth0
driver: 8139too
desc: "Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+"

I have a very similar problem.

I get the eth0 not present also; however, I am using Whitebox Linux, which is Red Hat Enterprise Linux compiled by whitebox.

Only thing, I've never had my card detected by linux.

when I do the lspci, I get:

Code:

02:01.0 Ethernet Controller: Linksys Gigabit Network Adapter (rev 12)

I tried homey's suggestion, and still get the same thing.

the sk98lin has been compiled per the linksys directions.

please help this

I am at a lost for what to do next

Thanks for the help in getting kudzu to reconfigure my system. I also had to take out physically my two other NICs (GN-1200TC from PCI PLANEX) before eth0 would work again. Unfortunately, I have to still understand why the other two NICs were causing trouble because I wish to use a shorewall 3 NIC setup. For now, I will stick with my store bought router.

should I try reinstalling linux?

No, but you might try not hijacking a thread and creating your own - I'd suggest in Linux-Hardware
