3. USING PUTTY TO CONNECT TO AWS EC2 (Part 1)  This tutorial provides a mechanism to allow the PuTTY client to connect to AWS EC2.  This tutorial may be found on AWS EC2 guide given below:  http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html  These are the requirements to get putty working:  Download and install PuTTY from the PuTTY download page [2]. Install the file named:  putty-0.63-installer.exe putty-0.63-installer.exe  Get the Public DNS of the EC2 instance.  Locate the private key “pem” file that you downloaded when you created the EC2 instance.  Enable inbound SSH traffic from your IP address to your instance. This should already be done if you followed the tutorial on AWS. 3 [2] http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

4. USING PUTTY TO CONNECT TO AWS EC2 (Part 2)  Putty does not support the “pem” file provided by Amazon. It will need to be converted to a “ppk” file.  To convert your private key  Start PuTTYgen (for example, from the Start menu, click All Programs > PuTTY > PuTTYgen).  Under Type of key to generate, select SSH-2 RSA.  Click Load. By default, PuTTYgen displays only files with the extension.ppk. To locate your.pem file, select the option to display files of all types.  Select your.pem file and click Open. Click OK to dismiss the confirmation dialog box.  Click Save private key to save the key in the format that PuTTY can use. PuTTYgen displays a warning about saving the key without a passphrase. Click No.  Specify the same name for the key that you used for the key pair (for example, sysc). PuTTY automatically adds the.ppk file extension. 4

5. USING PUTTY TO CONNECT TO AWS EC2 (Part 3)  The last step is to start the PuTTY SSH Session:  Start PuTTY (from the Start menu, click All Programs > PuTTY > PuTTY).  In the Category pane, select Session and complete the following fields:  In the Host Name box, enter ec2-user@public_dns_name.  Under Connection type, select SSH, ensure that Port is 22.  In the Category pane, expand Connection, expand SSH, and then select Auth. Then perform the following actions:  Click Browse.  Select the.ppk file that you generated for your key pair, and then click Open.  Click Open to start the PuTTY session. 5
