Changing the NICE DCV Server TCP Port

By default, the NICE DCV server is configured to communicate over port 8443. You can specify a custom TCP port after you have installed the NICE DCV server. The port must be greater than 1024.

To allow NICE DCV clients to access your NICE DCV server over the standard HTTPS port (443), we recommend that you use a web proxy or load balancer as a frontend gateway to redirect client connections to the server.

Ensure that you communicate any port changes to your clients, as they need the port number to connect to sessions.

Changing the NICE DCV Server TCP Port on Windows

To change the port used by the NICE DCV server, you must configure the web-port parameter using the Windows Registry Editor.

To change the server's TCP port on Windows

  1. Open the Windows Registry Editor.

  2. Navigate to the HKEY_USERS/S-1-5-18/Software/GSettings/com/nicesoftware/dcv/connectivity/ key and select the web-port parameter.

    If there is no web-port parameter in the registry key, create one:

    1. In the left-hand pane, open the context (right-click) menu for the connectivity key and choose New, DWORD (32-bit) value.

    2. For Name, type web-port and press Enter.

  3. Open the web-port parameter. For Value data, type the new TCP port number.

    Note

    The TCP port number must be greater than 1024.

  4. Choose OK and close the Windows Registry Editor.

  5. Stop and restart the NICE DCV server.

Changing the NICE DCV Server TCP Port on Linux

To change the port used by the NICE DCV server, you must configure the web-port parameter in the dcv.conf file.

To change the server's TCP port on Linux

  1. Navigate to /etc/dcv/ and open the dcv.conf with your preferred text editor.

  2. Locate the web-port parameter in the [connectivity] section, and replace the existing TCP port number with the new TCP port number.

    If there is no web-port parameter in the [connectivity] section, add it manually using the following format:

    [connectivity] web-port=port_number

    Note

    The TCP port number must be greater than 1024.

  3. Save and close the file.

  4. Stop and restart the NICE DCV server.
