How to find out what process is utilizing a port

[Otto Folprecht]

Hi. I need to find out what process is utilizing the port 8080. I do not have lsof (tied to man and run the command). Any suggestions. THX Otto

You can get lsof from here:
http://hpux.its.tudelft.nl/hppd/hpux/Sysadmin/lsof-4.77/

It's a very easy swinstall.

Run it as "lsof -i :8080".

Netstat -an can find ports in use but cannot tie them to a process.

If you go to www.iana.org, you will find that port 8080 is registered as an alternate http port.

Shalom Otto,

lsof is worth it even if you have to compile it. I've had better luck with compiling it versus swinstall, though we're mostly a PA-RISC 11.11 shop.

Great tool.

losf is the right tool here.

LSOF_64bit 1.0 lsof the open file utility for hpux 11.00 (64 bit) is what i use for my HP-UX boxes.
