I used VRRP on Linux machines. It worked very well. I used ipfilter rules on a firewall infront of servers to setup TCP connections by random. The rule is only needed for a setup packet because the firewall keeps track of established connections. (BTW: I did the same with the random netfilter module on Linux). Besides of that I used pound to loadbalance HTTP requests to multiple web servers. AFS seems to be generally a good idea to mirror filesystems but I do not have working experience with it. And it seems that FreeBSD has OpenAFS and an own implementation? (And I heard rumours that both are highly experimental?) Maybe it is good to collect all the small programs you can use for clustering and higher availibility together on a website. I do not know one yet. Regards Peter
