network configuration problem

Hey Guys,

I'm working on Red hat enterprise linux 4 . I config ip addresses are:
eth1 and eth0
I meet the problem one is that whenever ServerB restart only one network card can work properly, I need to ifconfig eth0 up manually.
The route for this server can only for one network card. when server up, either eth1 or eth0 is up , network cards cannot be up at the same time. Meanwhile, if eth0 is up , the route for eth1 cannot be added ,if eth1 up , the route for eth0 cannot added.

Your help is greatly appreciated!!

You can set your config under /etc/sysconfig/network-script/ifcfg-eth0 and ifcfg-eth1.
This will keep your config after reboot.

Wink it doesn't work

Thanks for your reply.

But this didn't work properly ,I have configure those two files already, but after server only startup only one network properly either eth0 or eth1, Which means we only have one netwrok card can be active after reboot.
After reboot, I can startup inactive netwrok card.
ifup eth1 or ifup eth0. I don't know if any problem on linux system , could you advise ?

Your support is great appreciated
