Here are the highlights of integrating 737 service fingerprint
submissions and 5 corrections since January 7. For help understanding
the format of matchlines, see http://nmap.org/book/vscan-fileformat.html#vscan-db-match.

match bitcoin 
m|^\xf9\xbe\xb4\xd9version\0\0\0\0\0.\0\0\0....\x71\x11\x01\0\0\0\0\0\0\0\0\0........\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\xff\xff......\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\xff\xff.............../Bitpeer:([\w._-]+)/\0\0\0\0\x01$|s

        This is really interesting. Bitcoin needed to make a
        backward-incompatible protocol change to add checksums to
        certain messages. But because all nodes need to be able to
        communicate with each other, they couldn't make this change
        incrementally. So they put a time check in the source code, and
        on February 20, 2012, all nodes instantly and simultaneously
        began to speak a different protocol.

        https://bitcointalk.org/index.php?topic=55852.0
        http://bitcoin.org/en/alert/2012-02-18-protocol-change
        https://en.bitcoin.it/wiki/Protocol_specification#version

        The source code literally said this:
        https://github.com/bitcoin/bitcoin/commit/f93d5f9ffe1e12079e560a735111735924726a06#L7R538
                // Version 0.2 obsoletes 20 Feb 2012
                if (GetTime() > 1329696000)
                {
                    vSend.SetVersion(209);
                    vRecv.SetVersion(209);
                } 

        Nmap's bitcoin.lua was patched in the nick of time in r28104.

        Unfortunately I think that this coordinated change instantly
        obsoleted all our existing Bitcoin matchlines! They'd only work
        against extremely old software that didn't know to change the
        protocol with everyone else, and there's no reason why that
        software would ever be used since it can't communicate with the
        rest of the network. Just imagine minding your own business and
        suddenly everyone in the world starts speaking a different
        language...

match http m|^HTTP/1\.0 200 OK\r\nDate: .*\r\nServer: BQTWWW/([\w._-]+) \(RSX\) \(RSX-11M-PLUS V([\w._-]+)\)\r\n|

        I previously wrote about the work of Johnny Billquist at
        http://seclists.org/nmap-dev/2012/q4/221. But I think I made a
        mistake there--the TCP/IP stack attributed to him should have
        been that of RSX-11M-PLUS, not DG/UX. Anyway, this is a web
        server for RSX-11M-PLUS, also written by Billquist. It's running
        on an emulated PDP-11!

        "This is not the page you are looking for\. \*waves hand\*" This
        is an automatic downloader program.

        This is a utility that allows you to play the video game Dwarf
        Fortress over Telnet. Telnet signature are often highly unique,
        even without identifying text, because of ANSI escape sequences
        and Telnet options.

match http m|^HTTP/1\.0 \xff\xfbAllow: GET \r\nAccept-Ranges: bytes\r\nCache-Control: no-cache\r\nCache-Control:

        This is quite a strange interpretation of HTTP. Note the mangled
        \xff\xfb in the status-line, that seems to run right into the
        header fields. It says the content-length is 2, but the body is
        empty.

match http m|^HTTP/2\.0 404 Not Found\r\n.*Server: Restlet-Framework/@major-number () \ 
@minor-number@@release-type@@release-number () \r\n *<p>The server has not found anything matching the request 
URI</p>|s p/Serviio media server http status/
        This is supposedly "HTTP 2.0". Look at the broken variable
        substitution (@major-number@) where a version number should be.

match http m|^HTTP/1\.0 200 OK\r\nDate: .*\r\nServer: HTTP Server\r\n.*<!--\n    M Comeau Dec 19, 2011\n    This page

        I think this is one of those things a service technician plugs
        into your car to interpret the error codes.

        The Wikipedia page for this OS says "Initial release: 1961; 52
        years ago." (But the system this fingerprint was taken from was
        probably a much newer release.)

match telnet m|^\xff\xfd\x01\xff\xfd\x1f\xff\xfb\x01\xff\xfb\x03\r\r\nGET / HTTP/1\.0\r\n\r\n\r\nPartedMagic login:

        Nmap apparently crashes the login program that comes with the
        shadow suite. You can see the assertion in the source code here:
        http://fossies.org/dox/shadow_4.1.5.1.orig/loginprompt_8c_source.html
        Parted Magic is a distro with disk partitioning programs.
