6.5.3 Enabling the Remote SSH

The demo application enables sshd for the SSH remote connection and avahi for the mDNS device discovery and hostname resolution. Users can use the hostname to connect to the evaluation board over SSH, without needing the board’s IP address

The user must perform the following steps to make an SSH remote connection.
  1. After the device connects to the target AP, LED (D5) on the SAMA5D27-SOM1-EK1 evaluation board turns ON in blue.
  2. Use SSH client tools like PuTTY on a PC to create an SSH tunnel. Open PuTTY and configure the SSH connection with the following settings:
    1. Set “Port” value as 22
    2. “Host Name (or IP address)” as sama5.local (see xrefFigure 6-11).
      Note: Ensure that the PC is on the same network as the evaluation board.
    3. Click Open to initiate the SSH connection.
    Figure 6-11. Use PuTTY to Create SSH Connection
    Note: In some networks, the “Host Name (or IP address)” for SSH connection is sama5.
  3. When connecting for the first time, a PuTTY Security Alert window appear.

  4. Click Yes to update PuTTY’s cache and continue connecting.
  5. The users can also use the ssh command on Linux to remotely control the board:
    1. Open a terminal on the Linux machine.
    2. Use the following command to initiate the SSH connection:
      ssh root@sama5.local
  6. The user can login with the following username and password:
    • username: root
    • password: r.
    login as: root
root@sama5.local's password: r
