Software to test IP Programming

Hello All..

I am searching for a program to be installed on Windows Platform that can listen for a specific TCP/IP ports and show the incoming strings and also can send a strings to the remote client......

Something like a telnet server, that listens to a specific port and shows me what strings are received and also I can send my strings, so i can test my programming (initializing connection, sending strings to the master to check strings parsing routines) for IP devices rather than going to the site to check if my code is working fine.

I found many programs that listens to any port i specify... but i can't see what strings are being sent or received.

Thank You
Sensiva

    Using Ethereal in promiscuous mode you can view ports and strings sent on a LAN but I you can't send. Want wrong with TELNET? If I recall you can do HTTP/GET stuff>

    Telnet??

    As I know, telnet connects to telnet servers, which means my computer is the client and the remote is the server, I want to do the opposite... My computer is the server who accepts the connections and the master is a client that connects to My Computer.

    Hey... Take it easy.. I don't think it needs all this headache .. only a small program (few 100kb) and everything will be fine.

    netcat (nc) for Windows or Cygwin will do this... 94KB, command-line interface.

    nc -l -p 4242 will listen on port 4242. You'll see strings that come in, and you can type strings in reply. No hex display/input, so it's mainly only useful for ASCII.

    Try this one, it is free to download, but I'll attach it to this post as it is nice and small, not sure what it was originally for, but it allows you to use it as a TCP/UDP server and client, RS232, sending Hex strings, ascii strings, or a combination in 3 string boxes at the bottom. All in all a DAMN handy program.

    I use it for all my testing needs... that and puTTY of course!
