RH Linux 7.3 networking on LH4R

[Greg Swanson]

I've installed Linux 7.3 which installs eth0 and eth1 with the same network cards and parameters, although the system cannot join a network because of the conflicts that exist.

Umm.. huh?

You've got an LH4 with 2 network cards, but they are being initalised with the same settings?

What does the /etc/sysconfig/network-scripts/ifcfg-eth* files say?

What does 'ifconfig -a' say?

What does 'lsmod' say?

What's listed in /etc/modules.conf for the ethernet devices (grep eth /etc/modules.conf) ?

Some details would help us greatly ;)

Hi Greg,
You musn't set the two network cards with the same parameters, change the settings in one of them and restart networking.

Although you are using Redhat there is a debian website that I used when I was setting up a home network with Redhat 7.3 that got me through all these sorts of problems. It is quite excellent.

If you try and set eth0 and eth1 to the exact same IP address neither will work.

Setting them to the same subnet but different addresses should work which is an advantage over HP-UX which will not tolerate two cards on the same subnet.

ifconfig will display all configuration information for all cards.

cat /etc/sysconfig/networkscripts/ifcfg-eth0

cat /etc/sysconfig/networkscripts/ifcfg-eth1

If they are the same change the IP address change one of them.

Then service network restart.

Thanks for the help, I may not have explained my problem clealy as this is the first time I've used a forum to look for answers. I only had one network card in the machine but it keeps thinking that there is two and gives all of the same parameters for the real card and the non-existent card.
I was pulling my hair out. I tried moving the card to the next slot ant the same thing happened. I moved the card to the first slot, and everything works fine now!!
