I only want to do this on the local host - not remotely.

netstat -na tells me if its open OK.

It would be nice to know what application has it open, but knowing its
open is better than knowing nothing. I only want vanilla Solaris
commands - not lsof, nmap or something like that.

There's Wolfgang's advice:

# cd /proc; pfiles * > /tmp/pfiles.out
and then check for the port 8000 in that output.

If you want to make it a single command, you can do something like this:

cd /proc; pfiles * | egrep '^[0-9]+: |port: 8000'

This will produce one line per process (and some errors for processes
that disappeared), but one of the lines will be followed by a second
line with "port: 8000" in it. Then you'll have the process id and the
path/command for the process.

I.e., you'll get partial output for more processes than just the one
that's listening on port 8000, but it'll give you the information
you're looking for.

Since the output of pfiles is multiple lines, it won't be trivial
to block the output you don't want. An awk or perl script could
probably do it, but you'll have to experiment.
