How do you tell what port a process is using? Thanks in advance for your help.

Hi Kathy

Try
netstat -an

Thanks Paula. I was doing a netstat -a, but not -an. I had put this message in for one of my co-workers who is downstairs in the machine room.

Kathy:

you can also use the lsof utility to determine the process that owns a port. netstat -an does not associate a PID to a port/socket. lsof does.

You can get a copy of lsof from:

http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/lsof-4.51/

it is an absolute life saver.

good luck

Kofi, thanks for the information on lsof. I downloaded it and installed it, but when I try to run lsof, it gives me an error message saying, "lsof was built for a 32 bit kernel but this is a 64 bit kernel".
Is there an lsof for a 64 bit kernel?

Kathy:

Yep - the bin version that is posted on the porting centre is 32 bit. excerpt from the website "Note that the binary releases of lsof on this archive will ONLY run on OS release they were compiled on and will run on 32-bit HP-UX only. If you have any other release of HP-UX, you must build lsof yourself from the source code."

I do not have a 64 bit OS and so cannot build it for you, but I know that someone posted lsof for 64 bit HPUX on the forums (unfortunately, the search feature is not working so I cannot dig it up for you...) would someone remember where the 64 bit version of lsof is?

Or if you want to build it yourself, it should be quite straightforward... you would need ansi c or gcc

Kofi, thanks for checking this out for me. I'm pretty busy right now and am pressed for time. I'll just wait and see if someone remembers where the compiled 64 bit version is.

I dont think i ever posted the statically linked 64bit version of lsof to the list, couldnt send it as an attachment due to site problems, lets try again with the new format site....
