Your EC2 server should be accessible using a certificate file that was issued
to you when you created the server. I access my EC2 boxen like so:
ssh www0.domain.tld
With bits in $HOME/.ssh/config to assist with this:
Host www0.domain.tld
ForwardAgent yes
User ubuntu
HostName ec2-###-###-###-###.compute-1.amazonaws.com
IdentityFile ~/Code/org/key.pem
This is equivalent to the following SSH invocation:
ssh -i ~/Code/org/key.pem ubuntu@ec2-###-###-###-###.compute-1.amazonaws.com
Also, ensure that your EC2’s firewall settings are allowing SSH traffic. The
allowance of SSH traffic is default for most of the security rules I’ve seen,
but it doesn’t hurt to double-check.
