2. Add SSH Keys to known_hosts

   for i in {60..63}; do ssh-keygen -R "192.168.1.$i"; done && for i in {60..63}; do ssh-keyscan "192.168.1.$i" >> ~/.ssh/known_hosts; done
   

3. Set Up 1Password Credentials

   Follow the 1Password Connect Doc to create 1password-credentials.json and save the access token to the file token.
