Installing new NIC card in curent system

tractng · 02-19-2008, 06:19 PM

Guys,

My old card just died. I plan on intalling the new card (Intel) on the current system. What file do I have to configure to make this change?

It is an rpath flavor (openfiler)

TIA,
Tony

I don't know anything about the distro you mention if that is what it is.
It depends on the setup. The module for the nic may be defined in /etc/modprobe.conf. If so change to the new correct module for the new nic and you restart networking service if you have already changed the card. Some distros may detect a hardware change and make the changes for you.

Brian1,

Thanks for your reply. What file do I have to go in and specify the IP address?

I don't know your distro as mentioned so can't say. If the module alias is listed in modprobe.conf I would not think change network IP would be needed.

Thanks for your reply. I did noticed there was a ifconfig-eth1:1 in the /etc/sysconfig/network-scripts location but nothing was in the file. I copied the text from ifconfig-eth1, but nothing happened.

I would get the following error message when restarting the network service or during post: device eth1 has different MAC address than expected, ignoring.

When I restart the network service, then I am able to get the card to work. My guess is since the new card went into the same pci slot, it maintiained the same ip address configuration but the mac has changed.

Btw, ifconfig-eth0 was my on board nic that I am not using since it is 100 mbs.

Still looking into issue.

Again not knowing the distro but my guess if there is a /etc/sysconfig/network-scripts/ifconfig-eth1 then in that file there is a line that says MAC=. It will have a series of 2 digit values. This is the hardware address of the nic. So you can do one of two things. Change the value to the one the new card is using which you can read on the card itself or maybe on the box the card came in. Or use the ifconfig -a command to find the mac value. Or just place # in front of the line to just rem it out. The ifconfig-eth1 file my guess is what also contains the IP value plus other info on network nic card setup.

Now normally a eth1:1 represnets an Alias IP in the Redhat family of distros. You can search google on Aliasing IP to learn about it if needed.
