<p class="MsoNormal"> Anyone know a very simple tool to manage a floating eth0:0 interface for failover type connectivity? I used to use Heartbeat but they've gone and over-complicated it. I don't want it starting services or changing anything else. I'm
about to re-write my own in perl again but if someone's already found something that might be quicker. <o:p></o:p></p>
