We have launched our Instance.

To access this instance through Windows, you need to download PuTTY and PuTTY key

generator to convert ‘.pem’ file into ‘.ppk’ file.

You can also refer this link for Setting up with Amazon EC2 Instance.

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/get-set-up-for-

amazon-ec2.html

Step 3: Access your EC2 Instance-

You need to PuTTY to access this Instance through Windows. But PuTTY reads, .ppk file only

for authentication so first we need to convert this .pem file into .ppk.

Connecting to Your Linux Instance from Windows Using PuTTY

If you are a Windows user, then you can connect your Instance using PuTTY. After you launch

your instance, you can connect to it and use it the way that you'd use a computer in front of

you.

Before you connect your Instance through PuTTY, complete the following prerequisites:

1) Install PuTTY for Windows

Before we install PuTTY, we need to understand it first.

PuTTY is an open source software that is available with source code. PuTTY is an SSH and

telnet client, developed originally by Simon Tatham for the Windows platform.

How to Download PuTTY?

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

For more information, you can also visit PuTTY’s homepage and can download it.

Link- http://www.putty.org/

2) Generate Putty Private Key ( .ppk )-

PuTTY does not support AWS private key format (.pem) generated by Amazon EC2. To

connect your Instance with PuTTY you need a PuTTY format key (.ppk). For this PuTTY has a

tool named PuTTYyGen which converts (.pem ) AWS key pair into PuTTY formatted key pair

(.ppk) .

Steps to generate PuTTy formatted key pair (.ppk):

(a) Download PuTTYgen -

You can Download PuTTyGen from the below link:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
