use netcat to find process for udp port

Hi,

I noticed that on my solaris 8 server, netstat revealed some UDP ports are open that have no corresponding processes and are listed as "reserved" on IANA. When I reboot the server they go off but later after the server is up they are on. I do not see the ports in any startup scripts, they are not in /etc/inetd.conf, so I was wondering if I could use netcat in some way to try and find a process that might light-up if I send something to the port. I have tried to use "nemesis" to send packets to the port but I don't see anything.

Any suggestions would be helpful.
