port 102 busy - which process is responsible?

[serohZeven]

Hi,

we have to maintain a HP9000 server system with installed HP-UX 10.22.

An application stops starting because port 102 is busy after boot up. We want to kill that process blocking port 102. But there seem to be not a tool at all to push the requested output to screen. We tried out ps -ef and netstat -aA. HP support says, lfos should work.

Has everyone yet another idea how to resolve the relation between process an use port number?

Thanx
Ulrich

Yes we have.

We once got an "unsupported" program from HP-support to list all processes, their open files and sockets.

I will try to attach it to this entry.

gunzip it first before using of course.

It seems the compressed exe is not attached.

I try again. If it fails again, maybe I can FTP or mail it to you ?

Get lsof tool for 10.20.

lsof -p tcp:102

or netstat -a|grep -i 102

Hi Ulrich,

Port 102/tcp is used by ISO - specifically the TSAP portion os ISODE. This is part of the OSI Transport Services - OTS/9000 which can by used by X.400, FTAM, FDDI or even X.25 custom apps.

Here's a doc on OTS/9000:

Sorry - the process responsible will probably start with "osi" or "ots"

You might want to check if it's installed

swlist | grep -i ots

Hi Ulrich,

You could use lsof.

You can download it:
