 +====== Connecting by SSH through PuTTY ======
  
 +Author: Eoin Joy
 +
 +
 +On Windows, you can use PuTTY to SSH to a server.

 +
 +  * By default you can enter an IP address in the "Host Name (or IP Address)" field and click open and you will be prompted in the CLI for a username to connect as and that user's password.
 +
 +  * These usernames and passwords can be found in the password safe currently located in the following folder: ''Errigal Shared Documents\Team\''
 +
 +  * Usually the server's host name (e.g. atlas.err) is entered, and the name is resolved by the DNS.
 +
 +  * It is optional but helpful to enter <username>@<hostname> in the host name field as it is rare to log in as multiple users per server, in this case you would log in as the user scotty.
 +
 +  * Setting can be saved and loaded as profiles and the list of profiles can be searched by entering text into the Saved Sessions field.

 +
 +  * The first time you connect to a given host, you must accept that host's rsa2 key as verification of the server's identity.

 +
 +  * For some servers (e.g. an Amazon EC2 instance) it is necessary to use a ppk file or a pem file as a private key for an extra layer of authentication on connecting to the server. (PuTTY uses .ppk)
 +
 +These keys are found in the following folders:
 +
 +''Errigal Shared Documents\Amazon EC2\dev keys\''
 +or
 +''Errigal Shared Documents\Amazon EC2\prod keys\''
 +
 +  * To know which key to use, if not named directly after the server you are connecting to, log in to the AWS console, https://aws.amazon.com/console/
 +
 +  * Click on EC2, Intances, and you will be presented with the listings of the instances, which have a key name value telling you which key to use.
