I have been trying to setup network card bonding on my CentOS server, and I must be missing something, because I cannot get it to work... At all. My server has two onboard 10/100/1000bT NICs, but I'd like to take advantage of some fault tolerance and redundancy because this server will eventually be colocated a few hundred miles away from me. The machine is freshly installed and my NIC configurations look like this: /etc/modprobe.conf /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 So what files do I need to create and edit to get my network bonding going (I'd like to run in mode 5 or 6)? How should the files look when I'm done?
Here is what I've got so far: /etc/modprobe.conf /etc/sysconfig/network-scripts/ifcfg-bond0 /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 But... The machine is inaccessible. What am I doing wrong?
I just tried this as well, also to no avail: /etc/sysconfig/network-scripts/ifcfg-bond0 I used the values originally present on eth0 from the fresh install with working networking. I did notice an issue with an IP conflict during a reboot. During startup, the machine was trying to bind the IP to (I assume) bond0, but it failed saying the "Another host is using that IP." For a simple how-to, this is starting to wear on my nerves.
The only machine using this IP was this same machine, before I started messing with the bonding settings. Everything worked fine when I just had the IP set static on eth0.
