  Notes on the Synology guide

  The command to restart the sshd service will likely not work. In this case, telnet in to restart the service

  sudo synoservicectl --restart sshd  # restarting the sshd service may fail
  telnet -l <username> <host_name>  # telnet into the NAS
  sudo synoservicectl --start sshd  # start the sshd service
