I am trying to configure a php scanner I found on this forum to a specific need.
I am trying to manipulate it so It will only scan the remote ip address of the user, no others. And also only to scan for popular services on the users system. Then of course all of it to be displayed to the user.
As you can see I haven't got to far in terms of scanning popular services, but I think I have set to only scan the remote ip address of the user:
