2 NICs

BinaryGrey · 08-11-2001, 11:09 PM

I have 2 ISA 3c509 cards in my box. Only one of them will load. So i have interfaces lo, and eth0. How do I get the other card on eth1?

What happens when you load them manually?

You need to tell the kernel to probe for the second network card if you are using two NICs of the same type. IIRC you will need to specifiy something like this on the LILO prompt

Code:

ether=0x300,5,eth0 ether=0x330,7,eth1

Assuming that your first card was on IRQ 5 at base address 0x300, and you second card was on IRQ 7 at address 0x330. Have a look at http://linuxdocs.org/HOWTOs/Ethernet-HOWTO-3.html#ss3.2 for a better explination.

Try the following:

edit this following file:

/etc/modules.conf

look where it says:

alias eth0 ......

copy that whole line and paste underneath. Change the 0 to a 1 (on the bottom line only!).
Save the file, reboot and both NICs should work!

Thank you everyone.

jharris - how can i find the base address and IRQ?

I am having a very simular problem with a fresh install of RH 6.2.
At boot during the loading interface Eth0 i am confronted with
-Determining ipinformatin for Eth0
-Operation failed.
There doesn't seem to be resourse conflicts after I ran a couple cat commands. Eth1 appears to load after the error with eth0. I'm new to the game and will monitor this post to see what else comes up.

In the meantime here's something to help with the original post.

Try (as root i think)
#cat /proc/pci
This will give detailed info including IRQ. Unfortunately PCI only - mebee someone can update for the isa cat command..

For all base address try
#cat /proc/ioports

Sounds like you must not have a static ip address on eth0, are you using dhcp?

how are you connected to the dhcp server?

On the 2NICS problem

If you can't get it to work right you may need to put the card in a windows box and configure the card using 3-com's utility with the settings you need. And you should probably disable the plug and play feature of the card.

Yes, i get my ip's through DHCP and have verified my mAC add at the server side. Still stumped but i'll hammer at it.

Thanks for reply

What is the output of the ifconfig command? If it shows both eth0 and eth1 then the kernel modules for the card are loaded. If it also tells you the ip address then you are in business. If there is no IP then you may need to look at your dhcp client settings. are you using dhcpcd or pump?

Try these commands: (substitute eth0 for correct device)

pump -i eth0

or

dhcpcd eth0
