Amazon EC2 : Connecting to Your Linux Instance from Windows Using PuTTY

Amazon EC2 : Connecting to Your Linux Instance from Windows Using PuTTY

1. Start PuTTY (from the Start menu, click All Programs > PuTTY > PuTTY).
2. In the Category pane, select Session and complete the following fields:
   1. In the Host Name box, enter user_name@public_dns_name. Be sure to specify the appropriate user name for your AMI. For example:
      • 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 root.
      • Otherwise, if ec2-user and root don't work, check with the AMI provider.
   2. Under Connection type, select SSH.
   3. Ensure that Port is 22.
   
   
3. In the Category pane, expand Connection, expand SSH, and then select Auth. Complete the following:
   1. Click Browse.
   2. Select the .ppk file that you generated for your key pair, and then click Open.
   3. (Optional) If you plan to start this session again later, you can save the session information for future use. Select Session in the Category tree, enter a name for the session in Saved Sessions, and then click Save.
   4. Click Open to start the PuTTY session.
   
4. If this is the first time you have connected to this instance, PuTTY displays a security alert dialog box that asks whether you trust the host you are connecting to.
5. (Optional) Verify that the fingerprint in the security alert matches the fingerprint that you obtained in step 1. If these fingerprints don't match, someone might be attempting a "man-in-the-middle" attack. If they match, continue to the next step.
6. Click Yes. A window opens and you are connected to your instance
