Which OS, and which command exactly? Because on those systems that I have access to netstat outputs nice headers that should be easy to understand if you know a bit about networking.

aa-unconfined
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>.
