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
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.
32 # We use the following set metrics for fingerprinting:
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.
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.
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.
53 # - Overall packet size - a function of all IP and TCP options and bugs.
55 # NEW SIGNATURE: Copy this value literally.
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).
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.
70 # - Don't fragment flag (DF) - some modern OSes set this to implement PMTU
71 # discovery. Others do not bother.
73 # NEW SIGNATURE: Copy this value literally.
75 # - Maximum segment size (MSS) - this setting is usually link-dependent. P0f
76 # uses it to determine link type of the remote host.
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.
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.
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
92 # - Timestamp - some systems that implement timestamps set them to
93 # zero in the initial SYN. This case is detected and handled appropriately.
95 # - Selective ACK permitted - a flag set by systems that implement
96 # selective ACK functionality.
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).
104 # NEW SIGNATURE: Copy the sequence literally.
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'.
110 # Fingerprint entry format:
112 # wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details
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
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
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
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.
137 # Option block description is a list of comma or space separated
138 # options in the order they appear in the packet:
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
145 # T0 - timestamp with a zero value
147 # To denote no TCP options, use a single '.'.
149 # Please report any additions to this file, or any inaccuracies or
150 # problems spotted, to the maintainers: lcamtuf@coredump.cx,

158 # WARNING WARNING WARNING
159 # -----------------------
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
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?
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.
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).
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.
