Re: what runs on port 9?

[Aaron Turner <aturner linuxkb org>]

netstat -a | more 
netstat -an | more (for reporting active ports based on portnumber instead
of looking it up in /etc/services like above)

or better yet:

lsof <some flag that I forget>

will do the trick.  

And of course, nmap is your friend.
