     22 #
     23 # This fingerprint database is adapted from Michal Zalewski's p0f passive
     24 # operating system package.  The last database sync was from a Nov 3 2003
     25 # p0f.fp.
     26 #
     27 #
     28 # Each line in this file specifies a single fingerprint. Please read the
     29 # information below carefully before attempting to append any signatures
     30 # reported as UNKNOWN to this file to avoid mistakes.
     31 #
     32 # We use the following set metrics for fingerprinting:
     33 #
     34 # - Window size (WSS) - a highly OS dependent setting used for TCP/IP
     35 #   performance control (max. amount of data to be sent without ACK).
     36 #   Some systems use a fixed value for initial packets. On other
     37 #   systems, it is a multiple of MSS or MTU (MSS+40). In some rare
     38 #   cases, the value is just arbitrary.
     39 #
     40 #   NEW SIGNATURE: if p0f reported a special value of 'Snn', the number
     41 #   appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
     42 #   means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the
     43 #   value of nn is not fixed (unlikely), just copy the Snn or Tnn token
     44 #   literally. If you know this device has a simple stack and a fixed
     45 #   MTU, you can however multiply S value by MSS, or T value by MSS+40,
     46 #   and put it instead of Snn or Tnn.
     47 #
     48 #   If WSS otherwise looks like a fixed value (for example a multiple
     49 #   of two), or if you can confirm the value is fixed, please quote
     50 #   it literally. If there's no apparent pattern in WSS chosen, you
     51 #   should consider wildcarding this value.
     52 #
     53 # - Overall packet size - a function of all IP and TCP options and bugs.
     54 #
     55 #   NEW SIGNATURE: Copy this value literally.
     56 #
     57 # - Initial TTL - We check the actual TTL of a received packet. It can't
     58 #   be higher than the initial TTL, and also shouldn't be dramatically
     59 #   lower (maximum distance is defined as 40 hops).
     60 #
     61 #   NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally.
     62 #   You need to determine the initial TTL. The best way to do it is to
     63 #   check the documentation for a remote system, or check its settings.
     64 #   A fairly good method is to simply round the observed TTL up to
     65 #   32, 64, 128, or 255, but it should be noted that some obscure devices
     66 #   might not use round TTLs (in particular, some shoddy appliances use
     67 #   "original" initial TTL settings). If not sure, you can see how many
     68 #   hops you're away from the remote party with traceroute or mtr.
     69 #
     70 # - Don't fragment flag (DF) - some modern OSes set this to implement PMTU
     71 #   discovery. Others do not bother.
     72 #
     73 #   NEW SIGNATURE: Copy this value literally.
     74 #
     75 # - Maximum segment size (MSS) - this setting is usually link-dependent. P0f
     76 #   uses it to determine link type of the remote host.
     77 #
     78 #   NEW SIGNATURE: Always wildcard this value, except for rare cases when
     79 #   you have an appliance with a fixed value, know the system supports only
     80 #   a very limited number of network interface types, or know the system
     81 #   is using a value it pulled out of nowhere.  Specific unique MSS
     82 #   can be used to tell Google crawlbots from the rest of the population.
     83 #
     84 # - Window scaling (WSCALE) - this feature is used to scale WSS.
     85 #   It extends the size of a TCP/IP window to 32 bits. Some modern
     86 #   systems implement this feature.
     87 #
     88 #   NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set
     89 #   to zero or other low value. There's usually no need to wildcard this
     90 #   parameter.
     91 #
     92 # - Timestamp - some systems that implement timestamps set them to
     93 #   zero in the initial SYN. This case is detected and handled appropriately.
     94 #
     95 # - Selective ACK permitted - a flag set by systems that implement
     96 #   selective ACK functionality.
     97 #
     98 # - The sequence of TCP all options (MSS, window scaling, selective ACK
     99 #   permitted, timestamp, NOP). Other than the options previously
    100 #   discussed, p0f also checks for timestamp option (a silly
    101 #   extension to broadcast your uptime ;-), NOP options (used for
    102 #   header padding) and sackOK option (selective ACK feature).
    103 #
    104 #   NEW SIGNATURE: Copy the sequence literally.
    105 #
    106 # To wildcard any value (except for initial TTL or TCP options), replace
    107 # it with '*'. You can also use a modulo operator to match any values
    108 # that divide by nnn - '%nnn'.
    109 #
    110 # Fingerprint entry format:
    111 #
    112 # wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details
    113 #
    114 # wwww     - window size (can be *, %nnn, Snn or Tnn).  The special values
    115 #            "S" and "T" which are a multiple of MSS or a multiple of MTU
    116 #            respectively.
    117 # ttt      - initial TTL
    118 # D        - don't fragment bit (0 - not set, 1 - set)
    119 # ss       - overall SYN packet size
    120 # OOO      - option value and order specification (see below)
    121 # OS       - OS genre (Linux, Solaris, Windows)
    122 # Version  - OS Version (2.0.27 on x86, etc)
    123 # Subtype  - OS subtype or patchlevel (SP3, lo0)
    124 # details  - Generic OS details
    125 #
    126 # If OS genre starts with '*', p0f will not show distance, link type
    127 # and timestamp data. It is useful for userland TCP/IP stacks of
    128 # network scanners and so on, where many settings are randomized or
    129 # bogus.
    130 #
    131 # If OS genre starts with @, it denotes an approximate hit for a group
    132 # of operating systems (signature reporting still enabled in this case).
    133 # Use this feature at the end of this file to catch cases for which
    134 # you don't have a precise match, but can tell it's Windows or FreeBSD
    135 # or whatnot by looking at, say, flag layout alone.
    136 #
    137 # Option block description is a list of comma or space separated
    138 # options in the order they appear in the packet:
    139 #
    140 # N	   - NOP option
    141 # Wnnn	   - window scaling option, value nnn (or * or %nnn)
    142 # Mnnn	   - maximum segment size option, value nnn (or * or %nnn)
    143 # S	   - selective ACK OK
    144 # T	   - timestamp
    145 # T0	   - timestamp with a zero value
    146 #
    147 # To denote no TCP options, use a single '.'.
    148 #

    150 # problems spotted, to the maintainers: lcamtuf (a] coredump.cx,

    158 # WARNING WARNING WARNING
    159 # -----------------------
    160 #
    161 # Do not add a system X as OS Y just because NMAP says so. It is often
    162 # the case that X is a NAT firewall. While nmap is talking to the
    163 # device itself, p0f is fingerprinting the guy behind the firewall
    164 # instead.
    165 #
    166 # When in doubt, use common sense, don't add something that looks like
    167 # a completely different system as Linux or FreeBSD or LinkSys router.
    168 # Check DNS name, establish a connection to the remote host and look
    169 # at SYN+ACK - does it look similar?
    170 #
    171 # Some users tweak their TCP/IP settings - enable or disable RFC1323
    172 # functionality, enable or disable timestamps or selective ACK,
    173 # disable PMTU discovery, change MTU and so on. Always compare a new rule
    174 # to other fingerprints for this system, and verify the system isn't
    175 # "customized" before adding it. It is OK to add signature variants
    176 # caused by a commonly used software (personal firewalls, security
    177 # packages, etc), but it makes no sense to try to add every single
    178 # possible /proc/sys/net/ipv4 tweak on Linux or so.
    179 #
    180 # KEEP IN MIND: Some packet firewalls configured to normalize outgoing
    181 # traffic (OpenBSD pf with "scrub" enabled, for example) will, well,
    182 # normalize packets. Signatures will not correspond to the originating
    183 # system (and probably not quite to the firewall either).
    184 #
    185 # NOTE: Try to keep this file in some reasonable order, from most to
    186 # least likely systems. This will speed up operation. Also keep most
    187 # generic and broad rules near the end.
