cannot obtain IP through dhcp?
Hello, my redhat9 machine has 2 ethernet cards on them, one connects to the cable modem, and one serves as gateway for NAT(eth0 for NAT gateway, eth1 for cable modem). However, the one thats connecting to the cable modem cannot detect IP address on boot, i have setup my ifcfg-eth1 to use dhcp which doesn't work, using ifup eth1 it says no link...cable?? or somethign like that. However!! when i switch to this 3rd NIC card i have, it(eth1) works! automatically! Can someone tell me how to setup the old one so it will auto probe IP from cable modem? does it have to do with crossover cable or all that?
ps. i have to make it work because the 3rd nic card is for my regular machine.
