Nmap is undoubtedly one of the must-have tools in a network administrator's arsenal. I have mentioned this tool a couple of times already but I failed to say that there is a front-end interface to nmap that makes it easier to use and manage. Dubbed Zenmap, this is the "official" GUI front-end for nmap.



So to those network administrators who prefer having a GUI tool to CLI-based tools, you no longer have any reason not to use nmap to test your network.
