Enable ssh login with a public key
Introduction
it is more secure and easier to login to a server over ssh if you place your public key on this server. This how-to shows in simple steps how to do this.
Generate keys
You only have to do this one time. You can and should reuse your public key for all ssh-servers.
Step 1 - creating SSH key pair
Make sure you are in your home directory.
ssh-keygen -t rsaIf you want so secure the access to your key with password, enter a password. Otherwise press enter two times.
Step 2 - Copying the SSH public key to the ssh server
The real magic happens here:
ssh-copy-id <username>@<ssh-server>Basically this command copies the file .ssh/id_rsa.pub to your ssh-server. You can either use an ip address or an FQDN (e.g. hcloud.simmy.ch) as ssh-server
Connect to the server
ssh <username>@<ssh-server>
