Putty is a communications program that is used on computers. It is a client program for SSH, Telnet and Rlogin network. The program is developed to allow secure login from a Windows computer to a remote UNIX computer. Simply put, Putty is used to remotely gain access to computers on the internet via Telnet and SSH. When you connect to a computer using Putty, anything you type in the window is sent directly to the machine you connected to. Likewise, you will receive information from the computer that you are connected to which will be displayed in the window. Information is encrypted before it can be transferred reducing the likelihood of having people on the internet gaining access to your private information.
To avoid password and usernames thefts secure login is enforced.
Putty is free and can be obtained by downloading from the internet. Many people do not know what Putty is, let alone know how to use it. What really takes place is that you run Putty on a windows machine and command it to connect to a UNIX machine. A window opens. Anything you type in that window is sent to the UNIX machine and anything you receive is shown in the window. You are actually working on the other machine but not sitting before it. Here are the steps:
1.Start “Exceed”. You need Exceed if you will be using X applications.
2.Find “putty.exe” and double click on it. This file is normally located in a folder on your computer named “Putty”.
3.The Putty program will start up by displaying a configuration dialog box. Look in the “Saved Sessions” for “ginger”. If it is there, select it and click the buttons marked “Load” and “Open”.

4.Click the option marked “SSH” from the protocol options shown.
5.Select the “SSH Tunnels” and then check the box marked “Enable XII forwarding” by clicking it to make a tick.
6.Click the “Open” button. The dialog box will disappear and then a ginger login screen will be displayed.
