I'm diagnosing an old Solaris 10 build and during port scans I've found an open port that's not on the approved list for this server.

I've tried various combinations of netstat switches but I can't seem to get the right output that gives me the associated service name or PID of the open port.

The feature set of netstat on this build seems to be limited compared to later solaris versions and other unix operating systems. netstat -tulpn for example doesn't work.

I also can't install lsof due to security restrictions.

Any ideas?
