equivalent of MS portquery for Linux & HP-UX to check Udp connectivity


Hi

To test if the firewall permissioned for a certain port (in my case, I need to test
for Udp port being permissioned), I would use portquery on the initiating node.

For Windows & Unix, I can use "telnet destination_IP port" to test tcp port
connectivity.  WHat about udp port on Linux & HP-UX ?
