SSH

Setup Remote Access by SSH Key

1. Create RSA Key Pair

   ssh-keygen

   NOTE: If an SSH key already exists you will be prompted to overwrite it - Don't do it

2. Copy the Public Key to the Server Using the ssh-copy-id command if it's available

   ssh-copy-id username@remote_host

   If the ssh-copy-id command isn't available this is an alternative

   cat ~/.ssh/id_rsa.pub | ssh username@remote_host "mkdir -p ~/.ssh && touch ~/.ssh/authorized_keys && chmod -R go= ~/.ssh && cat >> ~/.ssh/authorized_keys"

3. Authenticate to the Server Using SSH Keys

   ssh username@remote_host

4. Disable Password Authentication on the Server (Optional) Edit the /etc/ssh/sshd_config file and Add the following line (or update it if it exists)

   ...
   PasswordAuthentication no
   ...
   

   Save the file and restart the ssh service by running

   sudo systemctl restart ssh

   Before closing the terminal check that you are able to login from another terminal to avoid getting locked out
