There are two basic ways of testing KFSensor.
Open up your web browser on the same machine that KFSensor is running on and enter the following URL:
http://127.0.0.1/
A scanner is designed to examine a machine for open ports and to gain information on the services it is running.
By downloading a scanner and running it against the KFSensor IP address it is possible to see what both sides of an attack.
You can obtain a couple of good scanners from these locations on the web:
KFSensor will stop responding to scanner after a few multi-port scans as it will activate the KFSensor DOS protection mechanism, which will lock out the scanner.
It is best to run a scanner from a different machine to the one on which KFSesnor is running.
