   Assuming you eventually want to reprogram rstatd in order to get it to 
start on a static port, I have a link handy which explains how to do what I 
previously pointed out as "Possibility 2", which was to have rstatd set it's 
own listening port.

   Essentially I think it boils down to changing:
       server_addr.sin_port = 0;
   to:
       server_addr.sin_port = htons(<port number>);

   The code mods don't seem that bad; the sucky part is installing a modified 
rstatd on all the boxes.

   This is a page I've been referring to as I've been working on a networking 
project:
