** Tracking down a Process using a Port **

[Michael Gretton]

I need to find out which process ID is using a network port (socket). I am trying to start a web service using a port like 8000 and I am being told it is in use. Using netstat -a, i find that is in fact being used but how can I get the PID so I can kill it? Any help would be grateful,

Mike

You will probably need to install the lsof command. This can be found at the "Software Porting and Archive Centre for HPUX" and also at tucows.com . Perform a lsof with a -i option to look at tcpip stuff. This will list PID for any open connections it finds

Micheal,

You need to use lsof to get this information.

Try it from

http://hpux.asknet.de/hppd/hpux/Sysadmin/lsof-4.55/

It's easy,

Hello Michael,

AFAIK the best answer is "lsof" (list open files" used with the "-i" (internet) option:
lsof -i tcp:21

This will show you all processes using TELNET (i.e. TCP, and port 21).

Get it from the "HP-UX Porting Archives" near you...

HTH,
Wodisch

Hi Micheal:

lsof is definitely the tool for this job. Be aware that if you are running 64-bit 11x that you must download the source and compile it as the only binary versions available are 32-bit and will not execute in 64-bit land.

Hello,
I administer a hpux 11.00 64bit system and tried to compile the lsof-4.55 but got the following output:

Looking for ipis_s with /usr/contrib/bin/q4 ...
!!!ERROR!!! /usr/contrib/bin/q4 failed and produced the following output.

Configure can't use /usr/contrib/bin/q4 to examine the ipis_s
structure. You must do that yourself, report the result in
the HPUX_IPC_S_PATCH environment variable, then repeat the
Configure step. Consult the Configure script's use of
/usr/contrib/bin/q4 and the 00XCONFIG file for information
on ipis_s testing and the setting of HPUX_IPC_S_PATCH.

What is wrong with it?

thx
