i require an udp port scanner. as it's not tcp, this is not trivial, since all port scanners i tried were highly unreliable. a command-line driven tool would be the best.

i tried already with php sockets, but failed. tools like portmap or pcap are too heavy. i just need to check if udp port abcde is open (test package received) or closed (no package received, retry for 5 secs).

could you direct me to such a program? or write a dll for me (not for 3dgs - i use it in a winbinder application)? thnaks in advance
