Once you launch your ec2 Linux instance, make sure that the two status checks are done and turns green under the instances option of EC2 dashboard. This implies that the Linux machine is fully setup and is ready for work. Ensure that your instance allow inbound traffic for SSH(22 port) from security group.Before connecting to the instance, have two software’s clients installed on your PC namely PuTTY, a free SSH client for Windows. and Puttygen(to convert .pem to .ppk file). AWS doesn’t allow to connect to the EC2 Linux Instance directly using .pem file. you need to convert the .pem key pair file to .ppk format so that it can be used with PuTTY. You need to generate a .ppk file using the free Puttygen tool from the .pem key pair file of respective Linux machine instance.

If you create your own key pair using the command line, follow the recommendations at create-key-pair or New-EC2KeyPair Cmdlet for key type and bit length. If you create your own key pair using a third-party tool, be sure that your key matches the guidelines at Importing Your Own Public Key to Amazon EC2. The.pem file would have been downloaded when the key pair was created. You cannot get it again. If you have lost it, you're out of luck. You cannot use a.pem file that you generated yourself unless you imported that key into AWS before the instance was launched and assigned it to the instance.

Legend of the red dragon key generator. Generating .ppk file using Putttygen:

Open Puttygen tool and click on Load. Next select all files under file type and try to locate your .pem file for the keypair which is associated with your linux instance. Open that file and click OK.

May 01, 2015 This video shows how to use Putty Gen to create a Key Pair, upload Public Key into AWS Cloud, use that Public Key to launch an instance, and use the private key to access the VM instance.

Make sure that type of key to generate is set to SSH-2 RSA.

Click on Save private key To save the file in .ppk format so that it can be usable by putty.

PuTTYgen displays a warning about saving the key without a passphrase. Click YES

Important note to be kept in mind is to save the .ppk file with the same filename as .pem. (extension wil be added automatically)

Now we are good to go with establishing putty connection to linux instance from windows using Putty SSH client.

Putty Connectivity:

Open your Instances page on AWS EC2 console and select the appropriate Linux instance and note down the Public Dns name or Elastic IP if you have assigned already.

Open Putty Client and expand the tree as Connection SSH -> Auth. Under category pane on left side. Make sure that the screen looks like below

As in above screenshot, click on browse and locate the .ppk file which you have generated using Puttygen.

Now open open the sessions option under category pane and enter the host name.

/windows-xp-pro-sp3-key-generator-download.html. There is a standard format in which it has to be entered in hostname textbox to connect to instances on AWS. The format is user_name@public_dns_name.Or user_name@elasticip.

General usernames for the instances will be has below:

For an Amazon Linux AMI, the user name is ec2-user.
For a RHEL5 AMI, the user name is either root or ec2-user.
For an Ubuntu AMI, the user name is ubuntu.
For a Fedora AMI, the user name is either fedora or ec2-user.
For SUSE Linux, the user name is either root or ec2-user.

Otherwise, if ec2-user and root don’t work, check with the AMI provider(generally will be mentioned under usage guidelines tab of your marketplace or instances page)

Next, make sure connection type is SSH and port number is 22.

Click on open. If you are connecting for the first time, putty displays a security alert, just click OK.

Next a window with command line is opened and it will automatically authenticate to the machine with the given username.

How do I convert my Amazon Elastic Compute Cloud (Amazon EC2) Privacy Enhanced Mail (.pem) file to a PuTTY Private Key (.ppk) file? Or, convert a .ppk file to a .pem file?

Short Description

PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a .ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion. This tool, available for both Windows and Unix operating system, can convert keys.

Resolution

Windows - install PuTTYgen

Most Windows operating systems have PuTTY installed. If your system doesn't, download and install PuTTYgen.

Windows - convert a .pem file to a .ppk file

Start PuTTYgen, and then convert the .pem file to a .ppk file. For detailed steps, see Convert Your Private Key Using PuTTYgen.

Windows - convert a .ppk file to a .pem file

Start PuTTYgen. For Actions, choose Load, and then navigate to your .ppk file.
Choose the .ppk file, and then choose Open.
(Optional) For Key passphrase, enter a passphrase. For Confirm passphrase, re-enter your passphrase.
Note: Although a passphrase isn't required, you should specify one as a security measure to protect the private key from unauthorized use. Using a passphrase makes automation difficult, because human intervention is needed to log in to an instance or to copy files to an instance.
From the menu at the top of the PuTTY Key Generator, choose Conversions, Export OpenSSH Key.
Note: If you didn't enter a passphrase, you receive a PuTTYgen warning. Choose Yes.
Name the file and add the .pem extension.
Choose Save.

Unix or Linux - install PuTTY

Install PuTTY, if it's not already on your system.
