You might be interested in my project knockd_rotator. It's a simple pure python pair of server and client scripts. The client runs fine on termux and on anywhere with python and can trivially be translated to shell or any other language too if need be. The server must be run periodically (I provide systemd examples) to update the rules and that's it. Both client and server script just need to share a secret and modulo parameter and they will derive the same sequence for a given service. |
