Faltron Port Sniffer is a very simple data sniffer that will open a listening port for the local client to connect and direct the data to the server side and vice versa, in the process displaying the data to and from.

You must specify the local port for the client to connect to the sniffer and must not be already used by other process. You must also specify the remote IP or Host and the port for the client to connect to.

To check whether a local port is in use, go to the command prompt and type netstat -a (type netstat/? to know more about this command). You should use a port numbered 1024 and above. This is a experimental version, so there will be some bugs. I only tested and used in mIRC.
