From time to time it comes to a point that you have to put a host somewhere and then you or someone else needs to check if the host on a specific port is accessible.
Well, you can put up an IIS/Apache/SQL/mySQL/* and make it listen on 80 or any other designated port, but that requires some effort. There are probably other ways to do it, also.
I’ve put together some code using Visual Studio 2019 and my C# skills to create a small lightweight utility (12KB) that will act as TCP listener on any host you want to test. You can carry it around in your USB stick or put in your cloud drive.
Below a short video on how you can use it.
Hope you like it and if you do, either leave a comment or rate the post so I get some kind of feedback.
