sharpknocking

This project aims to implement the principles of port-knocking security hardening with C# over the mono framework and using the firewall provided by netfilter and iptables. Our code is licensed under LGPL so you can rehuse our code and/or libraries for other purposses and maybe contribute some to us ;)

iptknocker

This is a simple implementation of portknocking mechanism based in iptables recent module.

ipfilter authorisation tool

Tool for use with IPFilter to do "port knocking" and grey-list filtering of SMTP connections.

knock-android

This is the beginning of a port knocking client for Android. VERY EARLY STAGE : code is a CRAP. Thanks. Mostly written in a couple of hours instead of working on my Physics exam.

pk-el

Applicazione server/client scritta in Java,in grado di simulare la tecnica di autenticazione chiamata "Port Knocking". Il client "bussa" al server varie volte,secondo una sequenza prestabilita e su determinati numeri di porta. È una tecnica di difesa particolarmente efficace ... [More] perchè l'attaccante per effettuare l'accesso,oltre ad avere login e password,deve conoscere a quali porte bussare,quante sono,e soprattutto l'ordine esatto. Il client "bussa" al server attraverso l'invio di determinati pacchetti. Il server registra attraverso un filtro i pacchetti in un file di log,e se trova un riscontro positivo apre la porta al client per la connessione. In questo applicativo è implementato anche un algoritmo di criptazione per il login,cosicchè anche se si sniffa la sequenza di knocking,nome utente e password sono inviati cifrati. [Less]

knockd-utils

I created these utilities for myself in order to more easily use knockd's "one-time sequence file" feature. Two small programs are included: make_one_time_use_sequences.py - This randomly generates many sequences of knock stages. The number of stages, which ports are used, etc. ... [More] , is all configurable by the user. The created files are intended to be used by both knockd and knock.py. knock.py - This is a simple knockd client which is meant to be used with a file generated by make_one_time_use_sequences.py. A port-knocking daemon is not included--you should use knockd for that. There's nothing terribly ground-breaking here. But I figured I'd share to save someone else from spending their Sunday afternoon writing the same thing. That, and, I wanted to mess around with Google Code. [Less]
