Disable password access through SSH?

  • 772

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?

security ssh password remote-access

  1. Best Answer

    Just insert the following to the sshd config on the server (/etc/ssh/sshd_config)

    PasswordAuthentication no

    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.

  2. 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.

    PermitRootLogin no
