Tools used in this tutorial

So here’s what we’re going to need to make this all happen.

  • A tool called Putty (free)
  • An account on AWS (free)

Step One: Download and install Putty

Okay so let’s first get putty downloaded and installed on the local machine

If you already have putty or another SSH client you can skip ahead.

You can download the file here or follow the instructions below

Of course you can always head over to the Putty website to do the download of the software.

Choose that one and choose the link where it says “you can download Putty here.”

Choose the link that matches your OS and if in doubt get the 32bit version as that should still work on a Windows 64bit machine anyway.

The link to the software here are directly from the respective tool’s sites and are placed here simply for the reader’s convenience.

Step Two: Configure and Connect to your Linux machine using Puttygen and Putty

Process Key Pair

Okay time to fire up Putty and login to the instance you just created.

First we need to convert the Private Key downloaded in the previous step into some thing Putty can use.

Putty comes with a tool called PuTTYgen that we use to take the Amazon Key and convert it.

Go to your Apps in Windows and search for PuTYYgen and run the program.

Next up is to locate the key that we downloaded when setting up the Amazon AWS Instace.

Follow the steps in the screen shots in the gallery below to configure the Key for use in Putty.

Always be sure to take note where you store the files. Perhaps create a folder where you store all of these assets.

Putty Config

Now it is time to setup a Putty session that is used to install, configure and start and stop services on the AWS machine.

1. Enter the IP address of the machine to connect to

2. Give the Session a name

3.. Save it

4. Click on Data

5. Enter the login user name 

6. Click on Auth

7. Click on Browse

8. Search for the Amazon .pem file of your private key that downloaded when you created the Amazon Instance

9. Click on open

10. Click on Session

11. Click on Save

Click Open to connect the AWS Instance

Follow the steps in the screen shots below to configure Putty.

In Closing

The whole process to install and convert an Amazon key is pretty darn quick when you think about it.  Once it’s done you’re done for life on knowing how to leverage Putty with Amazon
