AWS ssh access 'Permission denied (

Answer 1

Another thing to check is PermitRootLogin and AllowUsers in /etc/ssh/sshd_config.

This debug1: key_parse_private2: missing begin marker appears even after successful key authorization if your user access restricted.

Answer 2

You are probably logging in as the wrong user. If it's a Ubuntu instance the command would be:

ssh -v -i ec2-key-pair.pem ubuntu@ec2-54-72-242-0.eu-west-1.compute.amazonaws.com

Answer 3

I had a similar issue, "key_parse_private2: missing begin marker" while using username 'ec2-user' but it got fixed when I changed to ubuntu as the user.
