I'll appreciate it ;)
Goggling gives a lot of links to libpcap based port knockers, but I dislike idea always running in promiscuous mode. Also "magic packet" is a sort of overkill for me, because I need access from random locations with different OS'es preferably without any additional tools.
If computer is untrusted, after logon I can change knock sequence without leaving any keys behind. Even if password gets compromised is not so dangerous in this scenario.
By iptables based I mean using ulog or ipq to forward packets to knock daemon, thus its undetectable from outside and can be very fast.
About a year ago I tested 5 or 6 port knockers but I didn't find any
suitable for me. Some had terrible cpu usage on my machine,
some not enough flexible configuration.
KH> Yes, there are. I use one for my work servers that is iptables based.
