1.3 avsm 23: # This fingerprint database is adapted from Michal Zalewski's p0f passive
1.13 frantzen 24: # operating system package. The last database sync was from a Nov 3 2003
25: # p0f.fp.
1.1 frantzen 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
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'.
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.
1.7 david 117: # ttt - initial TTL
1.1 frantzen 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
1.7 david 132: # of operating systems (signature reporting still enabled in this case).
1.1 frantzen 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
1.11 deraadt 144: # T - timestamp
145: # T0 - timestamp with a zero value

158: # WARNING WARNING WARNING
159: # -----------------------
160: #
161: # Do not add a system X as OS Y just because NMAP says so. It is often
1.7 david 162: # the case that X is a NAT firewall. While nmap is talking to the
1.1 frantzen 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.
