| You can see what keys were added to the machine
| |
| <code>juju authorised-keys list</code>
| |
| and verify the key fingerprint for the key you want to use
| |
| <code>ssh-keygen -lf /home/user/.ssh/id_rsa</code>
| |
| | |
| but you have to know/guess what user was installed by your charm
| |
| | |
| <code>ssh -i /home/user/.ssh/id_rsa -o IdentitiesOnly=true -vvv ubuntu@ec2-55-5-555-55.compute-1.amazonaws.com</code>
