Software Release - fwknop-2.0

fwknop-2.0 released After a long development cycle, fwknop-2.0 has been released. This is the first production release of the fully re-written C version of fwknop, and is the culmination of an effort to provide Single Packet Authorization to multiple open source firewalls, embedded systems, mobile devices, and more. On the "server" side, supported firewalls now include iptables on Linux, ipfw on FreeBSD and Mac OS X, and pf on OpenBSD. The fwknop client is known to run on all of these platforms, and also functions on Windows systems running under Cygwin. There is also an Android client, and a good start on a iPhone client as well. On a personal note, I wish to thank Damien Stuart for a heroic effort to port most of the original perl code over to C. Also, several other people have made significant contributions including Jonathan Bennet, Max Kastanas, Sebastien Jeanquier, Ozmart, and others. If there are any issues, please get in touch with me directly or send an email to the fwknop mailing list.

Update 01/03: Both libfko library that powers much of fwknop operations and the fwknop client can be compiled as native Windows executables. In addition, there are perl and python bindings to libfko as well.

Update 01/07: Damien Stuart has built RPM files for fwknop on RHEL5, RHEL6, Fedora 15, 16, and 17 and for other architectures the Fedora koji build system can produce.
