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, so I can't query with that. I guess I could do:
pfiles `ls /proc` | less
and look for "port: 80", but if anyone has a better solution, I'm all ears! Even better if I can look for the listening process without being root. I'm open to both shell and C solutions; I wouldn't mind having a little custom executable to carry with me for the next time this comes up.
Updated: I'm talking about generic installs of solaris for which I am not the administrator (although I do have superuser access), so installing things from the freeware disk isn't an option. Obviously neither are using Linux-specific extensions to fuser, netstat, or other tools. So far running pfiles on all processes seems to be the best solution, unfortunately. If that remains the case, I'll probably post an answer with some slightly more efficient code that the clip above.
