Hi,

My friend installed a program that listen to couple ports. However, the
fireware was blocking the ports. I was trying to open the ports but I had
no idea what ports the program was listening. So, I temporary put his
computer in the DMZ.

Is there a way to find out what ports the program is listening?

Thanks!

There may be an entry in the firewall log, or you could check the vendor's
help page. Can't be more specific without more info.

Your question is convoluted and missing information.

You are mixing port types. When you say "...listen to couple ports..." you are
inferring a
network protocol such as TCP/IP and a Trojan has opened up TCP or UDP ports.
Then you
mention FireWire. FireWire, Serial, USB, and PS/2 are examples of peripheral
communication
ports. Network protocol ports and peripheral communication ports are NOT the
same and must
be differentiated.

Then you mention about a DMZ. A DMZ is terminology expressed on SOHO Routers
where an IP
address of a LAN node is in the DeMilitarized Zone such that it has no FireWall
protection
and all networking posrts are open to the Internet.

In summation you have convoluted your question and provided insufficient
information to come
to any conclusions.

However, I can perovide you with a utility called TCPVIEW by Sysinternals -
http://www.sysinternals.com/Utilities/TcpView.html

This tool gives a dynamic GUI view of what program opens up what TCP/UDP port
and connects
to what Internet site. Not only will it show programs that open ports but it
will show the
fully qualified name and path of the executable opening said port and the
command line
switches used to load the executable.

I have no idea what I am talking about. but somehow you know what I am
talking about. So I think we are even for being the same fool. (as some
dead guy had said long time ago that only the fool could understand the
other fool.)

Thanks for the link anyway.

If your friend is using Windows XP you could also try the following command
line:

netstat -an

This will list the active ports on the computer and whether they are
listening or connected.
