Release Notes: This release fixes a bug in knock.py when sending a knock to a site not in the configuration file or when the configuration file doesn't exist.
Release Notes: Updated to work with iptables 1.4.21 and Linux kernels up to 3.10. The procfs entry was turned off in kernels >= 3.7; for older kernels, it is now /proc/ipt_pkd/stats. knock.py was switched to be a loadable module that can be imported into other Python scripts.
Release Notes: This release has been updated for Linux 3.x, and tested with Linux 3.2 and iptables 18.104.22.168

Release Notes: This release adds support for iptables 1.4.7 and 1.4.8 and Linux kernel 2.6.34.
Release Notes: This version was updated for Linux 2.6.32 and iptables 1.4.6. A new knock client was added, which is written in C# and works on both Linux and Windows and encrypts configuration data. A pre-built kernel module, an iptables library for vyatta community edition 5, and a small install script for vyatta were added.
Release Notes: This release adds support for iptables 1.4.4 and 1.4.5 and kernels 2.6.30 and 2.6.31.
Release Notes: This version adds support for libxtables, iptables 126.96.36.199, and Linux kernel 2.6.29. A port config option was added on the Python knock, so you don't have to have a bunch of UDP ports open on a firewall to pass a knock through to an internal client.
