PuTTY is an SSH and telnet client, developed originally by Simon Tatham for the Windows platform. PuTTY is open source software that is available with source code and is developed and supported by a group of volunteers.
PuTTY is a client program for the SSH, Telnet and Rlogin network protocols. These protocols are all used to run a remote session on a computer, over a network. PuTTY implements the client end of that session: the end at which the session is displayed, rather than the end at which it runs.
In really simple terms: you run PuTTY on a Windows machine, and tell it to connect to (for example) a Unix machine. PuTTY opens a window. Then, anything you type into that window is sent straight to the Unix machine, and everything the Unix machine sends back is displayed in the window. So you can work on the Unix machine as if you were sitting at its console, while actually sitting somewhere else.
This is a straight recompile of the existing source code. I provide this software as is and do not guarantee it in any way. That being said, if you do use this programs I’d like to hear of any problems you might have with it and I’ll see what I can do to fix them.
The current build is based on the beta 0.63 version of the source code. This software has been tested by me on 64bit versions of Windows Server 2003/2008 and XP/Vista/7.
