For example, I can easily type 3389 in the filter box to find out all devices that have Remote Desktop Protocol turned on that I can remotely log in without the problem. One thing I find is quite useful is its Filter feature that narrows down the scanning result based on my own criteria. For a large network, it uses up to 100 threads to speed up the performance. PortScan & Stuffis a free portable network scanning tool that identifies all active devices on your network, showing all open ports and additional information like hostname, MAC address, HTTP, SMB, FTP, iSCSI, SMTP and SNMP services. If you want just to run it without installing it on your computer, simply choose Portable after launching the tool. The downloaded software package comes with both installation and portable versions.
It works on Windows from XP up to Windows 7 and 8.1, both 32-bit and 64-bit. Not only that, it also allows you to remote shutdown or wakes up any PCs found on the network.Īdvanced Port Scanner is my go-to tool whenever I need to run to find any open ports on a particular computer. The software scans ports of network computers and finds any open well-known TCP ports, as well as their computer names and MAC addresses. With Advanced Port Scanner, you can scan hundreds of IP addresses simultaneously at high speed. There are free yet powerful network scanner tools made just for that purpose.
But it’s not necessary to have such a beast to accomplish a simple job such as finding out the open ports on the computers on the same local network. When it comes to network scanning, you may think of those very costly commercial products that not much people can afford.
