We have users complaining that their software uses ports in the 20002, 20000-20100, and/or 11444 range.
We cannot figure out what is blocking the ports. We ran netstat -an and it doesn't show the port as blocked.
The user says they use GDB agent (what ever that is) to send a system call to open the port 20002 and it fails. But works for ports 20000 and 20001.
Any thought on how to figure this out. I'm lost on this.
