Redhat 8.0 2 NIC Cards, trying to failover

jweiss · 06-02-2003, 05:52 PM

Hello,

I am running Redhat 8.0 with 2 separate NIC cards. I have assigned them each a differen IP address and everything is fine. But...I would like them to failover, so if one network connection is lost the other network adapter takes over... I can do this manually, but I would like to know if this is possible to automate. Thanks I look forward to hearing an answer.

I would probably write a script and stick it in a cron job. something like:

Code:

#!/bin/bash
ping OTHER_HOST -c 3 -w 5 > /dev/null
if [ $? == 1 ]; then
mv /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth-temp
mv /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/ifcfg-eth0
mv /etc/sysconfig/network-scripts/ifcfg-eth-temp /etc/sysconfig/network-scripts/ifcfg-eth1
service network restart
fi

It may need tweaking but it will give you a start.
