NetCat is known as "Swiss Army Knife" in network tools, and has Windows and Linux versions. It is designed as a simple and reliable network tool because it is short (1.84 is only 25 kb, earlier version or even smaller version) and has practical functions, read/write data can be transmitted over TCP or UDP. At the same time, it is also a network application Debug analyzer, because it can create different types of network connections as needed.I. Versio

supports the e parameter, which will run the program followed and bind it to the link.
If we /bin/sh bind through the e parameter and turn on listening, then when we use a remote host to connect to this host, it is equivalent to acquiring a shell. Let's try it out.
