Hi,

I installed RHEL 5 in my PC, already windows XP is running in my system. I am not able to connect to internet from Linux, but internet is working in windows XP.

I got the below out put for lspci -vv command for ethernet controller

when i restart network i got the below eror.

[[email protected] init.d]# ./network restart

Shutting down loopback interface: [ OK ]

Bringing up loopback interface: [ OK ]

Bringing up interface eth0: 3c501 device eth0 does not seem to be present, delaying initialization.

[FAILED]

[[email protected] init.d]#

Can any one please help me to sort out this issue. Please let me know if any more information required.

Thanks in advance.

I think the problem is device driver .
I think the linux kernel can support Rtl 8101 lan card.
And maybe,you should recompile the linux kernel.

win2tank

first run "ifconfig -a" and post your results


Try this:
check to see if you have a configuration file for your interface (with the assumption that eth0 is your interface):
/etc/sysconfig/network-scripts/ifcfg-eth0

create a backup copy of the file to your home folder

edit the original file to look like this:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

after you save the changes run:
"ifup eth0"

I hope this helps.

A common problem is the contents of your /etc/resolv.conf file. This contains the addresses of the DNS servers your computer uses to lookup internet addresses. IE, how to turn www.google.com into xxx.yyy.zzz.nnn (64.233.169.104 for one of several). Normally, you can set one of the addresses to your router gateway address. Also, your ISP will provide you with at least one or two that they provide for you. Finally, there are a number of top-level DNS servers that you can use if all else fails. In any case, post the contents of your /etc/resolv.conf file here and we can help you modify it to work, if that is indeed the problem.

Hi,

The kernel is telling you that it doesn't recognize the card.
It will not load a module and therefore you've got no device.
And that's what the network restart command is reporting.

Google says that the realtek card has its own source package
that needs to be compiled manually. It will provide the r8169
kernel module, which should be able to load fine in a general
purpose kernel.

Depending on the distro you're using somebody might have done
the compile for you and you can download it as a package!
Otherwise download the source code, untar, run make in the
created directory and modprobe -r the created module (if no
errors...)

Good luck!
