Onboard network port not working

**vaskbtech** · 02-07-2011

Hi,

Im using RHEL 4.2, here in bios level onboard network port is detecting. But when trying to fetch that network port i cant able to connect internet. when i put ifconfig eth1 the port is not available in onboard. Any solution for this,.,??.

thanks,

How many network ports on this system?
What is the output of:

Code:

lspci | grep -i ethernet

What is in the files:

/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1

1) The insmod command is used by kernel versions 2.4.X. RHEL4 is a 2.6 kernel. Google: how to load module linux 2.6.

Code:

man modprobe

2) You didn't provide any information Lazydog requested.

3) Unless you added this NIC *after* installing RHEL, it's unlikely the default e1000 driver is going to work. RHEL4 is older. There are many revisions of the e1000 driver and if the NIC is in a newer machine, it probably needs a newer version of the driver.

See Lazydog's post above (lspci command) to identify the NIC and then visit Intel's site for the latest driver code (which will likely need to be compiled.)

OK, you have 3 interfaces. Which one is being activated when you boot?

Can you also give the output from the following:

ifconfig
cat /proc/net/arp

I'm seeing 3 different MAC addresses here. So we need to edit your ifcfg-eth0 file and add a MAC setting to it so it will bind to the interface you want. L8ine line you should add is;

Code:

HWADDR=00:90:27:8B:EA:CB

Replacing the HW Addres I have above with one of the 3 you have given.

Then shutdown the interface and start it again. Check connection and repeat if necessary.
