According to:

http://advice.networkice.com/advice/exploits/ports/2001/default.htm

and

http://www.chebucto.ns.ca/~rakerman/port-table.html

this port can also be used for a "glimpserver" search engine.

Glimpse can be found at http://glimpse.cs.arizona.edu/index.html

Have you checked for this application?

Alright friends,
I have discovered this during my current project and I have the
following nmap data for your review:

Host  (x.x.x.x) appears to be up ... good.
Initiating SYN half-open stealth scan against  (x.x.x.x)
Adding TCP port 23 (state open).
Adding TCP port 2001 (state open).
The SYN scan took 48 seconds to scan 2002 ports.

neither are firewalled

I have identified port 2001 to be a common Trojan port so this has me
concerned and interested.  Is there a way to take advantage of
TrojanCow
installed by someone else?  I have no experience with this particular
trojan, so any input would be much appreciated.

Also, are there any other known uses for this port?  Because
TrojanCow
is a stupid little Windows manipulator so perhaps this is something
else.
