Hi

Check the output of your netstat -an command. This should show all bound
ports, and you should see something like:

tcp        0      0  *.538                  *.*                    LISTEN
udp        0      0  *.538                  *.*

If you see that on your clean booted box, then the ports are already bound
by something else rather than gdomap ;)

It is also possible that your /etc/hosts file is a bit weird and your
gdomap is only bound to one interface or another.

gdomap is a kind of portmapper for a kind of RPC, but uses quite a different
mechanism and port, and they're not the same thing.

It's fun, and very satisfying.
