                     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
1.7       david      41: #   appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
1.1       frantzen   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
1.7       david      50: #   it literally. If there's no apparent pattern in WSS chosen, you
1.1       frantzen   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
1.7       david      59: #   lower (maximum distance is defined as 40 hops).
1.1       frantzen   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
1.7       david      86: #   systems implement this feature.
1.1       frantzen   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: #
1.7       david      95: # - Selective ACK permitted - a flag set by systems that implement
1.1       frantzen   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
1.7       david     107: # it with '*'. You can also use a modulo operator to match any values
1.1       frantzen  108: # that divide by nnn - '%nnn'.
