Open port

[William O'Higgins Witteman]

I have just finished a fresh install of Debian, and while hunting down a
different problem I noted that I have an odd, open port on my system.
Here's the output of nmap localhost:

Starting Nmap 4.00 ( http://www.insecure.org/nmap/ ) at 2006-04-26 11:43 EDT
Interesting ports on localhost (127.0.0.1):
(The 1665 ports scanned but not shown below are in state: closed)
PORT     STATE SERVICE
22/tcp   open  ssh
25/tcp   open  smtp
111/tcp  open  rpcbind
113/tcp  open  auth
443/tcp  open  https
816/tcp  open  unknown
2628/tcp open  dict

Nmap finished: 1 IP address (1 host up) scanned in 0.285 seconds

What is the "unknown" process listening on 816?  I notice that this is
different port than it had before a reboot, but there was still an open
port (I think it had a port around 900-ish).  If I "telnet localhost
816" a session is opened, and I am informed that ^] is the escape key,
but that's all it says, and I don't know how to further investigate
this.

Any suggestions?  Thanks.
