How do I prepare my network for the Viz agent?

Last Updated:   |  Applicable Viz Versions: All


To prepare your network for the Viz agent, we recommend using Telnet. Telnet is a helpful utility tool that is used to troubleshoot connectivity issues to a server. It is available for both Windows and Linux machines.

Instructions for Windows/Linux

  1. Open the command prompt (if Linux, open the terminal window).
  2. Enter the Telnet command, the domain/IP address of the remote server, and the port.

    telnet 443
  3. Press Enter/Return.
  4. If successful, a blank screen will appear with a blinking cursor, and the title bar will display the '' address.Successful Connection Screen


If the connection fails, you will receive an error message with a brief description of the issue (e.g., connection refused, connection failed, unknown host, etc).

In the example below, the machine was unable to connect to the Ingress server on port 23. From this, we can conclude that the Planview Viz agent will also encounter the same behavior and will not work on your machine.

In some cases, further troubleshooting may be required to determine the source of the blocked communication, and you may need to reach out to your company’s network engineering team for assistance. 

Note: Beginning in Windows Vista and Windows Server 2008, the Telnet client is not installed by default. If you receive an error that Telnet is not recognized as a command, you can install it by running the following command from an Administrator command prompt:

dism /online /Enable-Feature /FeatureName:TelnetClient
