                     32: #
                     33: # We use the following set metrics for fingerprinting:
                     34: #
                     35: # - Window size (WSS) - a highly OS dependent setting used for TCP/IP
                     36: #   performance control (max. amount of data to be sent without ACK).
                     37: #   Some systems use a fixed value for initial packets. On other
                     38: #   systems, it is a multiple of MSS or MTU (MSS+40). In some rare
                     39: #   cases, the value is just arbitrary.
                     40: #
                     41: #   NEW SIGNATURE: if p0f reported a special value of 'Snn', the number
                     42: #   appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
                     43: #   means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the
                     44: #   value of nn is not fixed (unlikely), just copy the Snn or Tnn token
                     45: #   literally. If you know this device has a simple stack and a fixed
                     46: #   MTU, you can however multiply S value by MSS, or T value by MSS+40,
                     47: #   and put it instead of Snn or Tnn.
                     48: #
                     49: #   If WSS otherwise looks like a fixed value (for example a multiple
                     50: #   of two), or if you can confirm the value is fixed, please quote
                     51: #   it literally. If there's no apparent pattern in WSS chosen, you
                     52: #   should consider wildcarding this value.
                     53: #
                     54: # - Overall packet size - a function of all IP and TCP options and bugs.
                     55: #
                     56: #   NEW SIGNATURE: Copy this value literally.
                     57: #
                     58: # - Initial TTL - We check the actual TTL of a received packet. It can't
                     59: #   be higher than the initial TTL, and also shouldn't be dramatically
                     60: #   lower (maximum distance is defined as 40 hops).
                     61: #
                     62: #   NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally.
                     63: #   You need to determine the initial TTL. The best way to do it is to
                     64: #   check the documentation for a remote system, or check its settings.
                     65: #   A fairly good method is to simply round the observed TTL up to
                     66: #   32, 64, 128, or 255, but it should be noted that some obscure devices
                     67: #   might not use round TTLs (in particular, some shoddy appliances use
                     68: #   "original" initial TTL settings). If not sure, you can see how many
                     69: #   hops you're away from the remote party with traceroute or mtr.
                     70: #
                     71: # - Don't fragment flag (DF) - some modern OSes set this to implement PMTU
                     72: #   discovery. Others do not bother.
                     73: #
                     74: #   NEW SIGNATURE: Copy this value literally.
                     75: #
                     76: # - Maximum segment size (MSS) - this setting is usually link-dependent. P0f
                     77: #   uses it to determine link type of the remote host.
                     78: #
                     79: #   NEW SIGNATURE: Always wildcard this value, except for rare cases when
                     80: #   you have an appliance with a fixed value, know the system supports only
                     81: #   a very limited number of network interface types, or know the system
                     82: #   is using a value it pulled out of nowhere.  Specific unique MSS
                     83: #   can be used to tell Google crawlbots from the rest of the population.
                     84: #
                     85: # - Window scaling (WSCALE) - this feature is used to scale WSS.
                     86: #   It extends the size of a TCP/IP window to 32 bits. Some modern
                     87: #   systems implement this feature.
                     88: #
                     89: #   NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set
                     90: #   to zero or other low value. There's usually no need to wildcard this
                     91: #   parameter.
                     92: #
                     93: # - Timestamp - some systems that implement timestamps set them to
                     94: #   zero in the initial SYN. This case is detected and handled appropriately.
                     95: #
                     96: # - Selective ACK permitted - a flag set by systems that implement
                     97: #   selective ACK functionality.
                     98: #
                     99: # - The sequence of TCP all options (MSS, window scaling, selective ACK
                    100: #   permitted, timestamp, NOP). Other than the options previously
                    101: #   discussed, p0f also checks for timestamp option (a silly
                    102: #   extension to broadcast your uptime ;-), NOP options (used for
                    103: #   header padding) and sackOK option (selective ACK feature).

                    107: # To wildcard any value (except for initial TTL or TCP options), replace
                    108: # it with '*'. You can also use a modulo operator to match any values
                    109: # that divide by nnn - '%nnn'.
