Re: One machine only set-up

Thanks all. I _am_ using VMWare. Even though, I still wanted to try
within one box only for testing reasons (i.e. being able to write
scripts that launch a certain configuration: servers on ports, client,
etc., without the need of a whole network/few machines). It turns out
that it is not possible, since, the ipvsadm drops the port for the
local node. So I can have the director be one real server, but not
more than that.

Thanks again,
Roxana.
