PuTTY is an open source SSH client distributed under the MIT licence, originally written for Windows platform. Many system engineers use it as a handy tool to remotely connect to their Linux/Unix machines with the secured SSH protocol to administer the system from their desktop.
Nowadays, PuTTY has also been ported to run on mobile devices such as PDAs and smart mobile phones, so that you can access to your servers for emergency troubleshooting, restarting a service, rebooting the server, and so on. Of course, you need to have Internet access from your mobile device to your server, either using GPRS, 3G, Wifi, etc.
