Why should I verify connectivity for MangoApps ports using Telnet?

Verifying the MangoApps-specific ports in your environment can minimize connectivity and functionality problems. The ports can generally be tested using a command line Telnet client. Below are how to start Telnet in a terminal in Mac OS and in a DOS window on Microsoft Windows. After that, the commands to test each port are the same.

Steps for Microsoft Windows

Open a DOS command prompt and type: telnet /?

Since Telnet is not installed by default on Windows, you will know if you need to install it If you get an error like:

'telnet' is not recognized as an internal or external command, operable program or batch file.

If typing telnet /? shows the Telnet help and not the above error, you can skip to the Telnet Commands to Test Ports section.

If Telnet is not installed, you should be able to install it from a DOS command line by typing the below command. If you don’t get an error and the DOS prompt returns, it is installed. You MUST close the current DOS window and reopen a new one to be able to use the newly installed Windows Telnet command line client.

pkgmgr /iu:"TelnetClient".

Steps for Mac OS

On Mac OS X, navigate to the “Applications” -> “Utilities” folder and choose the “Terminal” app.

Telnet Commands to Test Ports

The Application server is based on where your datacenter is located such as: In the United States, Europe or Australia. Make sure you test against the appropriate application server. Application Server Tests First, find your appropriate data center from the headings below. Then run each Telnet command test. If there is a connectivity issue, you will receive an error after a short time. In most cases, a successful connection will require the terminal window or DOS window to be closed prior to attempting a subsequent test.
