For example for 3 knocks with randomly generated sequence it is 65535³ ≈ 2.8×10¹⁴. ![]() This method is not protected cryptographically so there are the following attacks possible:īrute-force - If you use the full range of possible ports 1-65535 then even very short knocking sequences give impressive number of combinations to test. ![]() The basic port knocking method uses a fixed sequence of ports.
