Looking for utility to monitor TCP/IP connection

[Oenone]

Hello there,

I'm looking for a utility which will allow me to connect a piece of internet
communications software to a port on my local machine, and which will
forward all data it receives to a port on a remote server. Any response from
the remote server should be passed back through the local connection too
back to the web software.

This will allow me to monitor the entire connection and see exactly what
data is sent and received.

The reason I want to do this is because I'm trying to write some software
that retrieves a particular web page. It works fine in my web browser, but
my code just isn't working. By "spying" on the connection in this way I hope
to be able to see what Firefox is doing differently to my own code.

If anyone can recommend any shareware/freeware for Windows XP that will help
me, I'd love to hear about it.

Thanks in advance,

How about using a packetsniffer
www.Ethereal.com

or analyzer www.analyzer.polito.it/

(both require winpcap)

Hi MEL,

Thanks for the suggestions -- I'll take a look at these.

I was hoping for a slightly less low-level solution than using winpcap,
something where I could type in a local port number and a remote host and
port number and it would just pass all the data back and forth. In the
absence of that, this may provide me with the answer though.

Best regards,
