Notes
To enable logging in from a specific remote client with no password (typically so scripts can connect with ssh or rsync):
- Generate a public/private key pair on the client using ssh-keygen
- Copy the public key file (~/.ssh/id_rsa.pub) from the client to ~/.ssh/authorized_keys
- If the latter file doesn't already exist, then it can just be a direct copy of id_rsa.pub.
- If the latter file does already exist, then id_rsa.pub can just be appended to authorized_keys.
- It may be necessary to manually log on once to the client from the host (using the same usernames as above) in order to add the client to the host's known_hosts file; I'm not sure about this part. Need to test.
- Manually log on from the client to the host to make sure that the host is added to the client's known_hosts file, otherwise the verification prompt may interrupt any processes trying to log on automatically.
- If you disable logins now (e.g. via Webmin's "No login allowed" option), you will still be able to log in from a client with an authorized key.
Specific commands for doing this may be found here.
