I'm setting up a server for backing up my desktop box remotely. I want to prevent remote password access to the server, permitting only users with private keys (AKA my desktop box) to access it. How can I block remote password access while allowing physical password access to the server?
Just insert the following to the sshd config on the server (
You might need to reload the ssh service
sudo service ssh reload
That should do the trick ;)
For more options type
man sshd_config in to your terminal.
Just a note about SSH access to servers - you may also want to disable the root user from ssh, this way at least hackers will have to guess the username as well.
