I am looking for an LTO tape library. Do you have one to spare?

fwknop security files touched by this commit SPA implementation for Linux and FreeBSD
head/security/Makefile
New port: security/fwknop fwknop,"FireWall KNock OPerator", implements
Single Packet Authorization (SPA).

        fwknop stands for the "FireWall KNock OPerator", and
        implements an authorization scheme called Single Packet
        Authorization (SPA). This method of authorization is based
        around a default-drop packet filter (fwknop supports both
        iptables on Linux systems and ipfw on FreeBSD and Mac OS X
        systems) and libpcap.

        SPA requires only a single encrypted packet in order to
        communicate various pieces of information including desired
        access through an iptables policy and/or complete commands
        to execute on the target system. By using iptables to
        maintain a "default drop" stance, the main application of
        this program is to protect services such as OpenSSH with
        an additional layer of security in order to make the
        exploitation of vulnerabilities (both 0-day and unpatched
        code) much more difficult. With fwknop deployed, anyone
        using nmap to look for sshd can't even tell that it is
        listening; it makes no difference if they have a 0-day
        exploit or not. The authorization server passively monitors
        authorization packets via libcap and hence there is no
        "server" to which to connect in the traditional sense.
        Access to a protected service is only granted after a valid
        encrypted and non-replayed packet is monitored from an
        fwknop client (see the following network diagram; the SSH
        session can only take place after the SPA packet is monitored):
