This tutorial will explain what PuTTY is, what it can be used for and how it works. What is PuTTY? 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. What can PuTTY be used for? With PuTTY you can connect to your server through SSH on the Windows platform. How do I use it? First, you need to download the program from PuTTY's website. You can download PuTTY here. Select your installation package depending on your OS type. (32 bit or 64 bit) When you first start the program it will look something like this. You can easily connect to your server by entering the Host Name or IP in the column and then click Open. For example: I'm trying to connect to otrealm.com, using SSH. Now click Open and the PuTTY terminal window will show up. NOTE: You can also save Sessions, like I've done above, then just enter all the details and under 'Saved Sessions' enter a name for this session and press Save. To load a sessions just double-click the session name or press Load and then Open. Now enter your username for your user, then press enter. When you type your password, there won't be any didigts showing. Don't worry it will be written and then hit enter to validate and connect. You've successfully connected to your server. This tutorial won't explain how to control your server with PuTTY because it will be a really long tutorial to cover all that.
