Your setup so far
To ssh into your instance
First, change the permissions of the .pem file so only the root user can read it:
chmod 400 /path/to/pem/file.pem
Then, ssh into the instance using your instance’s public DNS hostname
ssh -i /path/to/pem/file.pem firstname.lastname@example.org
Tramp helps me connect and work with the remote instance as if it were local. I can use the
dired buffer, search and edit files, etc, just as I would do locally. It’s a great way to gently immerse oneself into the remote server world.
To connect to the instance using tramp, edit your
~/.ssh/config file to add:
Host aws_ubuntu # the name you'd like to use for sshing Hostname ec2-n-nn-nnn-nnn.example.amazonaws.com # public DNS hostname User ubuntu # username of your instance (it may not be ubuntu) IdentityFile /path/to/pem/file.pem
C-x C-f /ssh:host:path-to-file your way to the file you want to edit. I’ve bound
C-x C-f to
C-x o to reduce key strokes for myself.
