Basic ssh

/home/user/.ssh/config

Host my_friendly_host_name
        User my_remote_user
        Hostname my_host_ip_or_name
        PreferredAuthentications publickey
        IdentityFile /home/user/.ssh/id_rsa_my_remote_host

1. Generate key in my local machine:

ssh-keygen -t rsa

Save that key under /home/user/.ssh/id_rsa_my_remote_host

1. Copy the public key /home/user/.ssh/id_rsa_my_remote_host.pub and paste into the file /home/my_remote_user/.ssh/authorized_keys under the remote machine.

If the `authorized_keys has other keys, add the generated public key at the end of the file.

1. Connect to the remote machine

ssh my_remote_user@my_friendly_host_name
