What process is listening on a certain port on Solaris?

Question

So I log into a Solaris box, try to start Apache, and find that there is already a process listening on port 80, and it\'s not Apache. Our boxes don\'t have lsof installed,

Answer 1

Here's a one-liner:

ps -ef| awk '{print $2}'| xargs -I '{}' sh -c 'echo examining process {}; pfiles {}| grep 80'

'echo examining process PID' will be printed before each search, so once you see an output referencing port 80, you'll know which process is holding the handle.

Alternatively use:

ps -ef| grep $USER|awk '{print $2}'| xargs -I '{}' sh -c 'echo examining process {}; pfiles {}| grep 80'

Since 'pfiles' might not like that you're trying to access other user's processes, unless you're root of course.
