i want to kill a tcp connection by killing its pid
with netstat -an i got the tcp ip connection on port 5914
but when i type ps -a or ps-e there is not such process running on port 5914
is it possible that because i do not log on with proper user account i can not see that process running?

You need lsof to see pids and ports, generally speaking. Some OS have network artifacts in a per proc directory subtree like /proc/$PID/, so you can find the port there through an entry name. The ps can show you the command line, but that does not have to reveal any socket ports.

I assume this to be the wrong forum.
Does your netstat provide the -p option? It will output the PID of the process, then.

i tried lsof.
i am not that much familiar with unix.
when i type lsof it gives me lots of information in command line in a way that i can not see the previous commands that i typed (is there any command like /p that bring information page by page?)
but in that given information from lsof i can not find neither the port i see the port 5914 nor its corresponding ip that i saw in netstat -a for that particular port.
is there any way too release that port?

yes excuse me i post it on related forum

one of my system ports are busy and i dont know how to kill it
in netstat -a i see that the port are being used with a given ip but in ps -e i can not find that port being used by a process.
how can i kill that process or release that port.

Use the less (or more ) command :

netstat -tlp | less
# netstat -tlpn
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

                              ^--- port                                         ^--- PID

Can't the gods move a thread to a new forum? It's just rdbms values!
