How do I know if the program is working? While the AntiSniff tests are being performed on your network a Scan Progress window shows you what is going on.

The third tab in AntiSniff is Scan Progress. This tab shows the details of the testing as it is being performed. The IP address of the machine being tested is displayed on top. The main window shows the detailed results of the current test as they are calculated. The bottom window shows the overall progress, with a percentage completed, of the testing.
