Hello Everyone,

I have just bought Dell Inspiron 1525 and installed RHEL 5 successfully.
I could not found ethernet (NIC) card with name eth0. I tried to configure it using system-config-network but also didnt work for me.

I need your help in this regard. If anybody knows how it can be configured, then please let me know.

When you say "I could not found ethernet"....do you mean the wired ethernet interface, or the wifi interface?

Have you run "ifconfig -a", to see if there are any interfaces listed, other than lo0? Also, since you're using RHEL5 (and paying for support), have you called RedHat?

Thanks for your reply.

I am talking about wired ethernet interface. I didnot run ifconfig -a. I was using RHEL 5 on my compaq desktop. There I used to up the device by "ifup eth0" and configure using "netconfig eth0".

I will try ifconfig -a and let you know.

I also want to know how to get connected to net using wifi.

I got RHEL 5 installation CDs for free as i was doing its course, so , i do not pay for the support. I use it for network administration research, thats it.

Regards.

Regardless, if you've got supported RHEL5, their tech support can hel you. "ifconfig -a" shows you all the interfaces that are configured (they may not be ACTIVE, though).

This is the output i got by issuing "ifconfig -a"

I have come across sit0 for the first time. Would you please tell me what it exactly is.

I will try redhat support also.

Thanks,

Best thing is tell us the chipset of the ethernet device. Use command ' /sbin/lspci -v ' and post ethernet section. Beins RHEL 5 is older than dirt basedon orginal kernel of around 2.6.16 but correct me if I am wrong there. And good Redhat type distro like Fedora 9 using 2.6.26 something after updates has tons of new hardware support over RHEL5. If you need RHEL 5 then I recommend compiling your own kernel 2.6.27.5 from ww.kernel.org site.

Thanks Brian.

This is what was the output of lspci related to ethernet:-

09:00.0 Ethernet controller: Marvell Technology Group Ltd. Unknown device 4354 (rev 12)
0b:00.0 Network controller: Broadcom Corporation BCM4310 USB Controller (rev 01)

Yes, my kernel version is 2.6.16.
How can i compile my kernel with 2.6.27.5 if i am not connected to internet? Also i never compiled my kernel before as i am a newbie.
Please advice.

Regards,
John

From my search on the net it looks like it will use the sky2 module. Not sure if included in the 2.6.16 kernel tree. I think is was like late 2.6.28 or 2.6.20 before part of the kernel tree but necessary part of Redhat precompiled rpm kernels. But as root try this command.
/sbin/modprobe sky2

If it does not find the module then you might be able to patch the kernel you have to use sky2 module. Worst case upgrade kernel which is not bad. I did have an issue using kernel 2.6.24 or higher under Redhat RHEL 5. Kind of why I decided to just do a full clean install of Fedora 9 on my new notebook.

If you dont have it let me know and will help you compile say 2.6.22 kernel. Hate to write that all down if not needed.

Brian

I have done full installation of RHEL 5 and on giving
"/sbin/modprobe sky2" as root and i got nothing.

I dont know how to patch kernel.

Please advise.

Regards,
john.

I am not sure on the sky2 module if it can be installed outside of the kernel tree. I would have to search for the sky2 module source and then you would have to install the kernel-devel-********.rpm for the kernel source to be installed. I think it would be easier to build your own. Not bad to do but you may need to install some addtional rpms for building purposes. Check this post for building a kernel. http://www.linuxquestions.org/questi...36#post1401136

Wonder why you stick with 2.6.16 RHEL 5. Can't you get a newer one such
as Linux centos52-64-dell 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64 ?

I have a Dell that gave me headaches with CentOS5.1 (CentOS = the exact free version of RHEL). But when I tried CentOS5.2, all problems go away.
As a matter of fact, I might stick with this for the rest of the computer's life..

Reading this related thread might convince you:

sorry on second thought, my hardwares seems to be quite different from yours. I cannot be sure CentOS5.2 will "cure your problem"..
