About adding tcping

**Describe your feature request**:
First of all, thank you all for contributing to the open source software, which works very well.
But I found that we often need to tcping during the process, I have been looking for software that can realize this function. networkManager makes me see the hope, so can you add a tcping function that?
I think this would be a very useful feature.
Thanks again for contributing to open source software!
