in AWS by (19.2k points)

I am a newbie to Amazon web services, was trying to launch an Amazon instance and ssh to it using putty from windows. These are the steps I followed,

  • Created a key pair.
  • Created a security group with the rule for SSH and HTTP.
  • Launched an instance of EC2 using the above key pair and security group.
  • Using puttygen converted the *.pem file to *.ppk
  • Using putty tried connecting to the public DNS of the instance and provided the *.ppk file.

I logged in using 'root' and 'ec2-user', and created the ppk file using SSH1 and SSH2, for all these attempts I get the following error in putty,

"Server refused our key"

Can you guys please help, any suggestions would be greatly appreciated.

Use ubuntu as the username. AWS has changed the username from ec2-user to ubuntu long back. So this should work!

If this doesn't work make sure that:

  • your port number is 22
  • you are using your public IP address rather than the DNS.
