Netcat has long held a near-mythical place in the toolkit of network administrators, security professionals, and power users. Lightweight, flexible, and occasionally described as the “Swiss Army knife” of TCP/IP, netcat (nc) offers raw TCP and UDP connectivity, simple port scanning, port-forwarding, proxying, and file transfer capabilities. Over time, many projects and wrappers have sprung up around the core concept—some bona fide, others sketchy. One such type of project is the “Netcat GUI”: graphical front-ends that aim to make netcat’s power accessible to users who prefer buttons and windows over the command line.
