Hi,
To check if a port is open you could run the netstat command.
netstat -l shows what processes are listening along with their ports
You could also run nmap on your machine, this will also show whats ports are open.

4. UNIX for Dummies Questions & Answers
Hello,
I know that there is a unix system process that checks periodically the ports and if it finds any zombies then it frees them (the period is set by a kernel parameter).
Can anyone tell me the name of the process and the kernel parameter ?

unconfined
UNCONFINED(8) AppArmor 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 to bugzilla at <http://bugzilla.novell.com>.
