Can you see any problem with me changing this operation.
I.E. allowing different port for real servers for localnode?
It will probably be a little slower but I can't see any other
problems?
The following server may be of use to people deploying
LVS directors. It's a redirection super server, i.e. it
runs on the director and listens on many ports and redirects
clients (only HTTP at the moment) in various ways.

The way I see it used is for e.g. if you had 2 WWW servers,
WWW1 & WWW2 then you would create a virtual service with
3 members. WWW1, WWW2 & VIP:VPORT(weight 0). When both WWW1
& WWW2 fail you can set the weight of the other to 1 and
configure inetrd to listen on the VIP:VPORT. ldirectord
could be configured to do this automatically I think.
cheers,
Padraig.
