[K12OSN] Server load balancing, made easy

[Jonathan Carter]

Hi!

I want to set up a lab with two servers and load balancing, and I've 
found the post below. Is this a good way of doing it? Do anyone perhaps 
know of some links that points to other methods of doing the below?

I must admit, I'm not familiar with rsync. How do I rsync between two 
servers' home directories if one server is 192.168.0.254 and the other 
one 192.168.0.253?

thanks
Jonathan
