Looking for a way to find out who or what device is blocking traffic on a specific port. Sort of like a trace route tool where you could designate the port to test with (UDP/TCP). I realize that UDP may be hard to do since it is a connectionsless protocol.
What you want is hping: http://www.hping.org/ Use something like: hping --traceroute [--udp] -p DESTPORT DESTIP I think Fyodor's new nping utility has similar capabilities, too. Hope this helps!
