Hello Kirk, |

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 |
| 11 |
suitable for me. Some had terrible cpu usage on my machine, |
| 12 |
some not enough flexible configuration. |

KH> Yes, there are. I use one for my work servers that is iptables based. |
| 16 |
KH> I don't have any links for you unfortunately but I have seen them. If |
| 17 |
KH> you are really interested I can probably track down one I saw that used |
| 18 |
KH> iptables and was a combination style. I also know of an open source |
| 19 |
KH> "magic packet" style that I could probably find a link for if you were |
| 20 |
KH> interested. |
