YAPS installs with no additional Windows components required. Advanced Port Scanner is a free port scanner allowing you to quickly find open ports on network computers and retrieve versions of programs running on the. Further, I’ve never liked the additional installation components either with Zenmap (such as winpcap). I would frequently go the scripted route if I want a complicated nmap run. Zenmap does provide a graphical interface, but I’ve never liked the interface as it is too busy. I don’t see this as a full replacement of nmap, but YAPS does offer a lightweight (132 KB) alternative to scanning within Windows in a graphical front end. Figure B below shows this functionality for scanning my entire home lab: Figure B These can be useful for scanning an entire network and continuously monitoring for presence changes. Notice how the Command text box is populated with a command after you entered the Target. Everyone loves having a program that is easy to work with and easy to understand. The engine that runs the port scanning is the actual nmap tool we described above. 4) Enter your network ID into the Target text box as shown in the following graphic. After starting ZENMAP, you can click and select several options which are translated to actual NMAP commands. YAPS offers additional options such as the continuous scan and the option to scan an entire range of IP addresses. On Windows 10, you can do so by clicking on the Search icon, typing zenmap, and clicking on Nmap Zenmap GUI. It is important to note that nmap, only scans for open TCP/UDP type ports.

Figure A below shows YAPS scanning a Windows server running VMware vCenter Server with the expected ports open: Figure A nmap can be used to scan your IP addresses. I frequently scan all ports, and YAPS takes that approach in allowing a single fixed range of ports in the interactive scan. Nmap does a good job of presuming the primary ports in use or allowing a range of ports to be scanned. YAPS does effectively all of the same nmap functionality except it is designed to scan all ports. Recently, I came across Yet Another Port Scanner, or YAPS. But even with the graphical front-end, Zenmap, I still find myself willing to try other tools to perform port scans if they can do a good job and bring additional functionality to the task. The de facto standard to scan networks has been nmap.
