Trying to SSH into an Amazon Ec2 instance - permission error

The problem is having wrong mod on the file.

Easily solved by executing -

chmod 400 mykey.pem

Taken from Amazon's instructions -

Your key file must not be publicly viewable for SSH to work. Use this command if needed: chmod 400 mykey.pem

400 protects it by making it read only and only for the owner.


You are likely using the wrong username to login:

  • most Ubuntu images have a user ubuntu
  • Amazon's AMI is ec2-user
  • most Debian images have either root or admin

To login, you need to adjust your ssh command:

ssh -l USERNAME_HERE -i .ssh/yourkey.pem public-ec2-host

HTH


I know this is very late to the game ... but this always works for me:

step 1

ssh-add ~/.ssh/KEY_PAIR_NAME.pem

step 2, simply ssh in :)

ssh user_name@<instance public dns/ip>

e.g.

ssh [email protected]

hope this helps someone.
