Secure Shell

The Secure Shell (SSH) daemon is enabled by default and listens on port 22.

Passwordless Authentication

See SSH HowTo for more information.

Passwordless authentication does not work if the ssh daemon is running with ‘!StrictModes on’ (default) AND directory and file permissions are set too loosely. They must be set as follows:

~/                        no write permissions to group or others
~/.ssh                    700
~/.ssh/authorized_keys    600
