How to Connect to a Datto device via VNC Locally and Remotely



This article discusses how to locally and remotely connect to a Datto appliance via VNC.


Virtual Networking Computing is a service running on Datto's devices that functions similarly to Remote Desktop connecting over port 5900.

You can connect to all SIRIS and ALTO 2 appliances by using VNC.

VNC Clients

Datto does not have a recommended VNC client, although you can use any of the following options for free:


Before attempting to log in through VNC, be sure to complete these tasks:

  • Download one of the VNC viewers above.

  • Check that your device is checking in to Datto's monitoring servers. If the device is not checking in, see the article Troubleshooting Checkin Errors to solve that problem first.

    If you are experiencing connectivity issues, local VNC is still an option as long as you can ping the local IP. 

Connecting to the appliance

  1. To log in to a Datto device, first connect to the device from your account on the Partner Portal.

  2. Select Devices > Status and select the device to access.

  3. From the Device Spotlight pane on the left, click the Schedule remoteVNC link.

    This opens the Advanced tab. 

  4. Once in the Advanced tab, you can find your device's backup-admin password in the Device Login field. The VNC password will be the backup-admin password.

    You can use this information to gain root access to the Datto appliance later.

  5. Move down to the Device Spotlight's Schedule New Task section. Select remoteVNC from the Schedule New Task drop-down menu, and then enter an email address. You will receive an email with a public IP address and port number that you can use to input into your VNC Viewer.

  6. Open your VNC Viewer. When prompted, go to the host section of the viewer and enter the IP_address:Port_Number contained in the email from Step 4.
    If you are accessing locally, just enter the local IP address of your Datto device. You do not need to enter a username.

  7. When prompted for the password, enter your VNC password (see Step 3) and accept. Close any windows that are open on the Ubuntu desktop, but do not close the VNC window itself.
