I was just pointing to another network tool used for all sorts of fine-grained networking jobs (eg. security testing and others) which might be helpful to others.

It was created by Laurent Constantin (https://linuxsecurity.com/features/introduction-to-netwox-an...) for his own needs and hence the TUI/GUI is not polished. But it is simple, direct and gets the job done which is what is important. And it is a mature tool (hence no need for active maintenance) available in all Linux distros.
