If you want to list the ports currently in use on an UNIX system:

$ netstat -an

If you are looking for the ports allowing access - try /etc/services.

If neither of these work, please post back with questions AND the OS and version you are using.

AA-UNCONFINED(8)                                                     AppArmor                                                     AA-UNCONFINED(8)

NAME
aa-unconfined - output a list of processes with tcp or udp ports that do not have AppArmor profiles loaded SYNOPSIS
aa-unconfined DESCRIPTION
aa-unconfined will use netstat(8) to determine which processes have open network sockets and do not have AppArmor profiles loaded into the kernel. BUGS
aa-unconfined must be run as root to retrieve the process executable link from the /proc filesystem. This program is susceptible to race conditions of several flavours: an unlinked executable will be mishandled; an executable started before a AppArmor profile is loaded will not appear in the output, despite running without confinement; a process that dies between the netstat(8) and further checks will be mishandled. This program only lists processes using TCP and UDP. In short, this program is unsuitable for forensics use and is provided only as an aid to profiling all network-accessible processes in the lab. If you find any bugs, please report them at <http://https://bugs.launchpad.net/apparmor/+filebug>. SEE ALSO
