Have you ever had a connection problem with X3 and need a quick way to check that the server has the correct port open and cannot access the server?

The first is Telnet. Because this utility is disabled by default, we need to enable it before we drill down and start checking the port on the server. To enable telnet through GUI, the graphical user interface, which is the window you are most likely to spend most of your time viewing, do the following:

Open the Windows start menu > type Control Panel > press Enter > programs > turn Windows features on or off > select Telnet client > press OK

Open the Windows Start menu > type "Control Panel" > press Enter > "Programs" > "Turn Windows features on or off" > Select "Telnet Client" > press "OK"

Alternatively, you can install telnet from an elevated command prompt:

Open the Windows start menu > type command prompt > select run as administrator > type "Dism / Online / Enable-feature / FeatureName:TelnetClient" > press Enter

Now that telnet is enabled, you can access it from a command prompt using the command "telnet".

When open, use the following syntax: open [URL or IP address] [port number]. For example, to check if port 80 is open on baidu.com:

After the initial connection message, if you see the prompt "press any key to continue", the port is open and responding to the telnet. If you see a "cannot open connection" or a blinking black screen, the port you are trying to use is closed. For more information about the telnet utility, see this document for Microsoft.

The PowerShell utility Test-NetConnection is another built-in Window utility that can be used to check if the port is open. This utility can be used for a variety of purposes, from providing you with a local IP address, verifying that you have an Internet connection, running TraceRoute (to see the network hops between the source and destination hosts), and scanning open ports. To access this utility, open the Windows start menu, type PowerShell, and then select run as Administrator (you do not need to check the open port, but allow access to other features of the utility).

In the Shell window, use the syntax Test-NetConnection [URL or IP address]-Port [port number]. To save some keystrokes, the command tnc can also be used. For our example, we will test port 80 of sageas.cn again:

We see that the result of TcpTestSucceeded is True, which tells us that the server of sageas.cn has port 80 open. Refer to this Microsoft document for additional information about the Test-NetConnection command.

For our connection to X3, as long as you know the IP address of the URL or X3 used to access X3, you can use these utilities to check that your Web server has the correct port open (default is 8124). Network server. These utilities may also be invaluable for solving many other network-related problems, but this is the best server discussed in another forum.
