How to identify the service in one port?

Hello,

My server crash many times in the last days. I´m found one script (.bs.pl) in /tmp (but my /tmp is noexec). After this, always, same after reboot, i´m see this using netstat -an:

udp 0 0 127.0.0.1:32769 127.0.0.1:32769 ESTABLISHED

How to identify the service (or script) running in this port? Always the script (after reboot) change the port.

I´m ran ps -aux but no see not different.

Thanks,
Minotauro.
