PORTS

ShivKumar_1 — Wed, 26 Feb 2003 23:27:08 GMT

Hi Experts,
I am trying to install SEQUELink server on my box it uses port 19995 , when I m installing it , it says PORT busy.
Is there a way of releasing the port? I have already stopped the "Sequelink" server. Its a fresh install. I have removed the earlier version too.

Thnks
SK

issue the command:

netstat -ntlp | grep 19995

see what process is currently using the port.

The last piece of information on the line from above will be the "pid/proc", so you can easilly find out what's using it.

Hi,

netstat will not show the process which is holding the port . So use lsof.

#lsof -i | grep 19995

will show the process and PID of the process holding port 19995.

Then you can kill the process using PID to release the port.
