getting 3 NICs to work
 

Is there any limitation (perhaps in the kernel??) to having more than 2 NICs? I keep trying to install a 3rd NIC into my system and it always replaces an existing NIC so I only have 2 usuable.

im on RH8

thanks

I've got 3 NICs in a system with Slackware 8.1. All my NICs are the same. So far, I know that 2 are working (haven't been able to test #3 yet).

Firstly, disable PnP in the BIOS. You'll also need to make sure that all your modules are properly installed for them. What kind of NICs are they? Can you post the contents of /etc/modules.conf? Also, if they're different NICs, make sure you've got all the modules installed by typing lsmod.

What happens when you type:

ifconfig eth0 up
ifconfig eth1 up
ifconfig eth2 up
ifconfig -a <could be ifconfig -all I can't remember off hand>

(these command might be different for RH 8 but use the RH 8 equivalents and let us know)

got it to work... i figured theres gotta be some way to force it into the config i want so...

i manually created /etc/sysconfig/network-scripts/ifcfg-eth2. i then looked at the ethernet card itself and noted the MAC address. so in the ifcfg-eth2 file, i entered this lines:

BOOTPROTO=none
ONBOOT=yes
HWADDR=<mac address>

as well as the other pertinent IP info. then rebooted... works fine now.

thanks for your advice! this might work for you too if you cant get your 3rd NIC up and running.

Good to know. As soon as I get a chance to test #3 I'll look into this. Thank you.:D
