Then let me provide a rebuttal rant. I don't see any issue with his
question. What if perhaps one of us on this list recognizes those ports as
being an unreleased trojan that has not hit Bugtraq? I see no issues with
him raising his question to this list. Instead, let me ask you this. Should
we promote the public reprimand of an individual for what he believes to be
a valid question that others might see, forcing them into hiding where
further questions might have been posed? Do you want to claim the
responsibility of being the one to send them into hiding?
In my world, there are no such thing as stupid questions in this industry. I
remind you that this industry itself is quite young. Therefore we are all
learning as we go. I think a more appropriate response would have been just
your suggestions to use the sniffer and try locally connecting to those
listening ports. I do remind you, egos in this industry are the largest
cause of people not learning more than they already know. I also remind you
that they cause others to be afraid to ask what could have been, questions
that benefit others.
If we are not a part of the solution, we are part of the problem.

I dont want to sound like a pompous arse, but I think we should be
careful with asking questions like this. In the tradition of making
oversimilified and romantic analogies to the biological world, the
internet, and the world's public networks are like forrests. There is a
certain degree of chaos and a certain degree of natural order to their
basic operation. the chaos factor comes from the human interaction with
teh technology.
</RANT>
Trojans, and backdoors are equally as unpredictable. you
can with one line (in inetd) append a line binding a shell to ANY port.
You can write ANY number of programs or scripts to do the same on
unprivileged ports without root. from the network stuff like that is even
less predicatable because of the plethora of client connection initiation
done BEHIND the firewall. some innocuous client software could use the
higher port numbers for nonpassive communication or something. it could be
anything. have you tried to connect to the host targeted on that port?
throwing shell commands at it? if you have console access to teh machine,
look at all process, if there is a live connection, sniff it. the
wilderness of our networks can be incredibly dynamic, we have to cope with
this, and be innovative and dilligent in our conquest to grok the vast
expanse of information. do your part to contribute to the
"bodiless exhultation that is the matrix". heh. oi. BRAAAAAAZIILLLLLLLL!.
