RHEL-5 problem

r.007don · 07-21-2009, 04:05 PM

I have installed RHEL-5 in my system for the first but my system is not able to find a ethernet (eth0) device on my system. I have used many GNU/Linux distros but never found this kind of problem.
When I type the command : ifconfig eth0 <IP add.>
it gives the error: no such device found.
How can I install the ethernet?

Maybe if you told us what kind of hardware you're using, we could help. And since you have RedHat Enterprise, have you contacted RedHat support, or checked their knowledge base? You are paying for it, since you're using RHEL, so take advantage of it....

I am using it for learning purposes and am just using the trial. I have not paid for it.
My ethernet device is:
Realtek Semiconductor Co., Ltd. RTL8101E PCI Express Fast Ethernet controller
(as shown in fedora)
are there driver packages availiable which I can download and install?

I use a laptop and hence cannot use another network card.
Thanks.

Your card would have to be extremely strange for the system not to automatically find it. Have you tried running the command "lspci"? Also try running an "ifconfig -a" so it can list every network device it knows about. Can you paste/attach the output of "dmesg" so we can better understand what's going on with your system? Hope this helps.

we have used D-LINK PCI ADAPTER(DFE-520 TX, 10/100mbps fast ethernet) for dell desk top pc.

RH (and CentOS) 5.x have had some trouble with those Realtek cards. I believe Alan on CentOS forums made a driver for it.

Hrrm, I *think* this is it.

I thought they'd fixed that issue, but perhaps that's in 5.3, and not earlier versions. Also, I see that if Alan still has it in elrepo, I suspect that means it doesn't yet work properly, despite its wide use.
