I'm fairly new to linux/unix and I've built two Fedora 4 servers running sendmail.
I want to use these two servers as our mailhub so they need to be load balanced accross the two machines. I know that with Windows 2003 Server you can use something called NLB but have no idea how to do this with linux.
Could somebody help me out so that the are load balanced and if one goes down the other carries on using something like a virtual IP. I don't want to use round robin.
Also is there a simple way of if the config is change on one server for it to be copied to the other. This isn't as much of a problem as the load balancing.
