Killing a process to free up port

[Sanjay Duhan]

Hi,

I have an application which uses some specific port. A lot of time this app dies and when the port is free some other application binds to this port.
Now I want to know which process is using this port so that I can kill.
Well I want to free up this port.

Iam havinh HP-UX 11 server.

Thanx
Sanjay Duhan

There is a product called lsof that can help you with this as well. It is found at any of the porting centers...

Hope it helps

Hello,

as you know the used port try "lsof" which is able to display the associated processes in most cases (for each process that allocates a file descriptor)

example:

# lsof -i:23
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
inetd 17768 root 5u inet 0x2b2f940 0t0 TCP *:telnet (LISTEN)

You can see Port 23 is in use by a TCP SErvice "telnet" and the responsible process is inetd with PID 17768.

"lsof" is available at the HP Porting Center:
http://hpux.cs.utah.edu/
There search for "lsof".

Regards,

Andreas
