Have you looked at port knocking? |

A friend once mentioned on a forum that he'd managed to set up static libwrap |

rules in hosts.allow|deny for addresses that don't change and additionally |

port-knocking for himself to open up port 22 for a few minutes. I don't |

recall how he did this, only that he claimed to have done it. |
