Need Help Creaing a Script that can Ping a UDP Port

[wfernley]

Hey everyone,

I was curious if anyone can help me create a script that will ping a UDP port on a PC. I was able to create a script that can ping a TCP port like 3306 (MySQL) but the program I am having to ping is using UDP. I want to add this script to my website.

Does anyone know if this is possible and how to do it?

Thanks!

FWIW, 'ping' isn't really the right word to use here - technically speaking, if you ping a host you're sending an ICMP echo request packet, and you aren't directing it at any particular port.

Do you mean "make a connection (attempt) on a TCP port"? UDP is a stateless protocol (unlike TCP) so there isn't really a 'connection'.

Perhaps the best place to start would be the documentation for nmap [insecure.org] which has the ability to perform UDP scans?
