How to find a process using a port value

[Clint Gibler]

I need a way to discover what process on the 11.11 server I have is using a cetain port (port value = 12349) so that I can kill it as I need to free the port up again. I could re-boot but it would be easier if there was a way to find the process.

Use lsof to find the process on the local machine using port 12349

# lsof -i@servername:12349

in case you do not already have it installed.

what is lsof? I try the command you gave me but it just says sh: lsof: not found.
does it need to be run from someplace or is this a feature I don't have installed?

Shalom,

lsof is a non-standard but very useful comand to accomplish your goal.

Click the link posted earlier

swinstall the depot.

Run the command posted earlier to identify the process for death.

You may want to see if lsof is on on your system and then by specifying its full path if it exists.

# whereis lsof
