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

You might not want to, but your best bet is to grab the sunfreeware CD and install lsof.

Other than that, yes you can grovel around in /proc with a shell script.
