I myself use this method to open up the SSH port for a particular IP address. When you try to open a particular URL on my website, you get a 404 because that document doesn't exist. The webserver logs this. A script in the background sees in the log that this happened, and opens up port 22 to the IP address which requested the non-existant URL.
Aren't these all different versions of portknocking ? All of them work untill someone outside can figure out the pattern of events - at most I would call this security by obscurity - Trivial to detect but good enough for some low security requirements _______________________________________________ Full-Disclosure - We believe in it.
