entry on firewall log

[Don Bedsole]

Hi all,
I've noticed on my firewall log a couple of tcp connection attempts (from 
different IPs) with port 6000 as the source port on the remote host and port 
7212 as the destination port on my box.  Is there another application besides 
XWindows that uses port 6000 and that someone would be using to try to 
connect to me?  I'm not concerned about, obviously my firewall is working.  
But I thought if I asked, I might learn something.  Thank you.

Also, a question about list etiquette.  After someone answers your question, 
is it ok to post a thank you message?
