  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 '.'.

 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.
