NetCat

       Netcat is a TelNet client that can be used to send information from one machine to another. It's commonly called the 'swiss army knife' due to it's functionality and common use with forensic investigators.

How it works: a listener needs to be established on the machine that you wish to pass data to. This is accomplished with the command "netcat -v -l -p 2222 > [filename].txt". The -v puts netcat into verbose mode, which will display status messages. The -l is the listening switch. Finally, -p is to secifiy the port to listen on. The ending portion after the greater-than sign is the output file.
To then send a command from a machine to the listener, you'll run: "[some command] | netcat [ip of listener] [port number]". The [ip of listener] is the ip address of where the netcat listener is.
Overall, netcat is a easy and quick way to send information from one machine to another.

Where to download: The version of netcat that I enjoy and have found to work the best is the beta version from nmap. Download can be found here: http://nmap.org/ncat/.

Personal remarks: Netcat is a fairly easy to use tool that can transfer files and information between computers quickly. That is, if you get it set up right. Initally using netcat, it took a number of failed attempts to finally realize the format of commands. Then even more failed attempts to realize that the firewall was blocking the port we were sending info through. After those user 'blunders' the tool is extremely easy to use and pretty efficent.
