Hi - I've released fwknop-1.8. This is a major release that adds the ability to run the fwknop client on Windows systems from Cygwin, so you can now authenticate to iptables/fwknopd from Windows. Also, although this is of less interest to people on this list, fwknop now supports ipfw firewalls on *BSD systems as well. http://www.cipherdyne.org/fwknop/ -- Michael Rash http://www.cipherdyne.org/ Key fingerprint = 53EA 13EA 472E 3771 894F AC69 95D8 5D6B A742 839F
