How to find the pid to stop a process....

vous · 08-14-2003, 03:00 AM

Hello All,

I would like to know how can I find out which process (pid) is running on a certain port so I can stop it?

I can imagine it is somewhere around the netstat -a command... I know the process is running on 8080....

Any thoughts...????

OK, but where in the output do I relate the port and the PID?

$ ps -aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.0 1336 440 ? S Apr03 2:07 init
root 2 0.0 0.0 0 0 ? SW Apr03 0:00 [migration_CPU0]
root 3 0.0 0.0 0 0 ? SW Apr03 0:00 [migration_CPU1]
root 4 0.0 0.0 0 0 ? SW Apr03 0:01 [keventd]
....

Do you know the name of the process? If you do, the second entry in ps above ( root 2 0.0... ) is the PID.

To kill it:
kill -15 2
Where 2 is the pid of the process (assuming the process you wanna kill is migration_CPU1

).

So further down your ps string, find the name of the process and kill it similarly. If 15 doesn't kill it, send:
kill -9 pid
instead. A 9 signal is not as clean as a 15, but sometimes is necessary.

For stopping an httpd server though (assuming apache):
apachectl stop
Should suffice...

Cool

OK, but my question was how do you know ON WHICH PORT that pid is running?

Any other thoughts...??

I figured it out...it is:

$ netstat -nap | grep 8080
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 2352/tnslsnr

Your question was kind of vague, but even so, it wasn't exactly what you decided... You found which port, but then you've also now found out how to stop it

Cool
