I have a webhosting business all runnning on various Freebsd i386 boxes. I 
was wondering if there are any good howto's on doing this ? The services id 
like to cluster are,
bind 9.2.3
UW imap

>From what i understand there are a couple ways to do this. The load balancer 
method where one machine acts as a load balancer for nodes that run your 
services like apache, sendmail, DNS. So when load becomes so just 
add another machine to help take off some of the load or when a box fails the 
rest of the machines in the cluster pick up in its place.

the other way is to do it like Solaris does with veritas cluster services. 
where each machine runs a service and is monitored by the cluster and in the 
event of a failure...the service & IP & all would get moved to another box ..

any help would be great thank you
