How Port Scanning Works Scanning your computer is a simple task. Our server will attempt to open a connection to various ports on your computer, and make note of any open ports. Port numbers of interest will have details about what the port may be used for. A report will be compiled that will show you a list of open ports on your system and specific information about each port. Several scanning options exist, and may be controlled by the user.
Windows file sharing test is performed with every scan.
Our server will attempt to query your computer to see if it is advertising any services with a NetBIOS request to UDP port 137. If successful, our server will attempt a connection to TCP port 139 and request a list of shared resources. Any disk drive or shared folder resource will be tested to see if an actual connection is allowed. A full report of this process will be given. Testing TCP ports is also performed with every scan and checks for more general issues.
