How does AntiSniff work to find the packet sniffing computers? AntiSniff performs 3 classes of tests: operating system specific tests, DNS tests, and network latency tests. All of the tests may be run together to give a high degree of certainty as to whether or not a computer is packet sniffing. The program has a graphical interface that allows you to configure the network to test, schedule re-occuring tests, generate reports, and set up alarms. Just enter in the network to test and hit the Scan button.

The Hosts To Scan is configured in the first tab of the AntiSniff UI. This is the only configuration setting that is required before you can start scanning a network. Just enter in an IP address, a network IP range, or a file with a list of hosts. That's it. Now you can press the Scan button to start scanning.
