   I had a look.  It might be possible, but it looks like it would require 
some reprogramming work in C and recompiling the source for rstatd to get it 
to happen.  [And then installing the modified package on all of the 
machines...]

   I found two possibilities in the code for what needs to change.


Possibility 1:
   It sounds like the call to svcudp_create() within rstat_main.c might need 
to specify the port number.  This is based on what I found within the third 
paragraph of:

   http://www.iana.org/assignments/sun-rpc-numbers


Possibility 2:
   The setting of:

      server_addr.sin_port = 0;

   in rsysinfo.c and/or rup.c needs to be set to the port number you want, 
rather than 0.



   That's my quick stab at this, anyway.
