When you download the pem file for accessing the VM over SSH, make sure you
change the permissions on the file.
SSH does not like to use keys that other users can touch, so I suggest (I
named my key 615-sysadmin.pem):
$ cp ~/Downloads/615-sysadmin.pem ~/.ssh
$ chmod 400 ~/.ssh/615-sysadmin.pem
Also helpful for accessing the VM is to alias it in your SSH config. For
example:
Host sysadmin
Hostname ec2-0-0-0-0.compute-1.amazonaws.com
Port 22
User root
IdentityFile ~/.ssh/615-sysadmin.pem
Then you can access the VM by running
$ ssh sysadmin
Hope this helps!
