Unable to ssh from an ec2 instance

See original GitHub issue

I tried accessing play-with-docker instance using ssh from ec2 instance (can’t do from my local machine because of firewall blocking port 22). I checked the outbound rules but all ports are open.

Following error shows up when I try to ssh a pwd machine,

Permission denied (publickey).

This is because you need to generate a key locally to connect. Try with ssh-keygen

Nice. Would be nice if you can share here so others don’t have the same issue.

I don’t know whats goes on exactly, but I edited “/etc/ssh/sshd_config” in the node to enable root authentication with password and permit port forwarding and reset root password. Those changes didn’t let me to authenticate neither with password nor publickey. Then I rollback my changes, but no success. It seems those changes had a permanent effect on ssh service. Finally I test a new node without any modification and everything was ok.
