listing of locally open ports along with it connection to foreign IP
Address with it's PID number. Now pick up this PID number & look into
Windows Task Manager to see which process does the PID number belongs
Besides this tedious technique, a simpler technique is to use "Process
Explorer" from Sysinternals or "TCPMon".
However if your server is UNIX based, then you can try "netstat -antp"
for TCP & "netstat -anup" for UDP protocols connections currently

Besides this, running a Vulnerability Scanner (like Nessus) against
this server is also a recommended step before it gets totally

The problem is: with netstat i only see the ports daemons are listening
on. I want to know the process that is using the outgoing port, that is,
Is there a way to know this?
Thanks in advance.
