Security

You might want to connect to the machine remotely. Securing your machine is a must because the default password is too easy to guess (We don't want to change the password because it would make other configuration more complex).

Copy the SSH Public Key to the Device

1. Follow Setting Up Connection 1.

Disable Password Authentication for SSH

1. Switch the workplace to the Jetson devices by either ssh or IO devices.
2. Open SSH daemon config file by running:

   RSAAuthentication yes
   PubkeyAuthentication yes
   

4. Add the following contents or un-comment existed one:

   PasswordAuthentication no
   

5. Save the file
6. Restart SSH daemon for changes to take effect by running:

   sudo service sshd restart
