asked on

2 or more nic cards

I have setup one nic card on a freshly installed redhat linux, and it work fine as an eth0. I would like to ask if say i would add another nic card of the same brand, what do i need to configure? Do i just installed the card and it will automatically give eth1 and i will just have to add its ip address?

and what if the nic card is not supported on the redhat package, but the driver can be downloaded at its support site, how can i configure to work properly as a second nic card on the linux box?

thanks.

reyta,

You will need to configure the new card as well - linuxconf worked for me, or the RH installer makes it really simple since you have a fresh install.  But before you get there, its worth checking that the cards are assigned to differernt IRQs (in your system bios.)  The IRQ problem cost me weeks!

good luck, George

Vijay (vsamtani) has provided an excellent explanation above of the necessary steps.  If you use this method, it should ensure your familiarity with the proper networking config files (which is a *good* thing, if you plan to continue to administer linux systems).

On the other hand, linuxconf will do all of that for you once you have identified the proper driver for your card.  If this config is a one-time deal, and you want to just get it out of the way, then linuxconf will probably be more what you want.

An additional note - if your network card(s) are PCI, and your motherboard BIOS is halfway decent, you generally will not (although there are a few exceptions) have to specify an IO address or an IRQ for your cards.

What kind of ethernet card(s) are you using, BTW?

i am using rtl8029, and the rh6.1 linux detected it at boot...i check /etc/modules.conf and found another eth1 was added...then i edit /etc/sysconfig/network-script/ifcfg-eth0 to desired new ips and saved it as ../ifcfg-eth1 and the reboot.  thanks.
