23#
24#
25# This fingerprint database is adapted from Michal Zalewski's p0f passive
26# operating system package.  The last database sync was from a Nov 3 2003
27# p0f.fp.
28#
29#
30# Each line in this file specifies a single fingerprint. Please read the
31# information below carefully before attempting to append any signatures
32# reported as UNKNOWN to this file to avoid mistakes.
33#
34# We use the following set metrics for fingerprinting:
35#
36# - Window size (WSS) - a highly OS dependent setting used for TCP/IP
37#   performance control (max. amount of data to be sent without ACK).
38#   Some systems use a fixed value for initial packets. On other
39#   systems, it is a multiple of MSS or MTU (MSS+40). In some rare
40#   cases, the value is just arbitrary.
41#
42#   NEW SIGNATURE: if p0f reported a special value of 'Snn', the number
43#   appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
44#   means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the
45#   value of nn is not fixed (unlikely), just copy the Snn or Tnn token
46#   literally. If you know this device has a simple stack and a fixed
47#   MTU, you can however multiply S value by MSS, or T value by MSS+40,
48#   and put it instead of Snn or Tnn.
49#
50#   If WSS otherwise looks like a fixed value (for example a multiple
51#   of two), or if you can confirm the value is fixed, please quote
52#   it literally. If there's no apparent pattern in WSS chosen, you
53#   should consider wildcarding this value.
54#
55# - Overall packet size - a function of all IP and TCP options and bugs.
56#
57#   NEW SIGNATURE: Copy this value literally.
58#
59# - Initial TTL - We check the actual TTL of a received packet. It can't
60#   be higher than the initial TTL, and also shouldn't be dramatically
61#   lower (maximum distance is defined as 40 hops).
62#
63#   NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally.
64#   You need to determine the initial TTL. The best way to do it is to
65#   check the documentation for a remote system, or check its settings.
66#   A fairly good method is to simply round the observed TTL up to
67#   32, 64, 128, or 255, but it should be noted that some obscure devices
68#   might not use round TTLs (in particular, some shoddy appliances use
69#   "original" initial TTL settings). If not sure, you can see how many
70#   hops you're away from the remote party with traceroute or mtr.
71#
72# - Don't fragment flag (DF) - some modern OSes set this to implement PMTU
73#   discovery. Others do not bother.
74#
75#   NEW SIGNATURE: Copy this value literally.
76#
77# - Maximum segment size (MSS) - this setting is usually link-dependent. P0f
78#   uses it to determine link type of the remote host.
79#
80#   NEW SIGNATURE: Always wildcard this value, except for rare cases when
81#   you have an appliance with a fixed value, know the system supports only
82#   a very limited number of network interface types, or know the system
83#   is using a value it pulled out of nowhere.  Specific unique MSS
84#   can be used to tell Google crawlbots from the rest of the population.
85#
86# - Window scaling (WSCALE) - this feature is used to scale WSS.
87#   It extends the size of a TCP/IP window to 32 bits. Some modern
88#   systems implement this feature.
89#
90#   NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set
91#   to zero or other low value. There's usually no need to wildcard this
92#   parameter.
93#
94# - Timestamp - some systems that implement timestamps set them to
95#   zero in the initial SYN. This case is detected and handled appropriately.
96#
97# - Selective ACK permitted - a flag set by systems that implement
98#   selective ACK functionality.
99#
100# - The sequence of TCP all options (MSS, window scaling, selective ACK
101#   permitted, timestamp, NOP). Other than the options previously
102#   discussed, p0f also checks for timestamp option (a silly
103#   extension to broadcast your uptime ;-), NOP options (used for
104#   header padding) and sackOK option (selective ACK feature).
105#
106#   NEW SIGNATURE: Copy the sequence literally.
107#
108# To wildcard any value (except for initial TTL or TCP options), replace
109# it with '*'. You can also use a modulo operator to match any values
110# that divide by nnn - '%nnn'.
111#
112# Fingerprint entry format:
113#
114# wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details
115#
116# wwww     - window size (can be *, %nnn, Snn or Tnn).  The special values
117#            "S" and "T" which are a multiple of MSS or a multiple of MTU
118#            respectively.
119# ttt      - initial TTL
120# D        - don't fragment bit (0 - not set, 1 - set)
121# ss       - overall SYN packet size
122# OOO      - option value and order specification (see below)
123# OS       - OS genre (Linux, Solaris, Windows)
124# Version  - OS Version (2.0.27 on x86, etc)
125# Subtype  - OS subtype or patchlevel (SP3, lo0)
126# details  - Generic OS details
127#
128# If OS genre starts with '*', p0f will not show distance, link type
129# and timestamp data. It is useful for userland TCP/IP stacks of
130# network scanners and so on, where many settings are randomized or
131# bogus.
132#
133# If OS genre starts with @, it denotes an approximate hit for a group
134# of operating systems (signature reporting still enabled in this case).
135# Use this feature at the end of this file to catch cases for which
136# you don't have a precise match, but can tell it's Windows or FreeBSD
137# or whatnot by looking at, say, flag layout alone.
138#
139# Option block description is a list of comma or space separated
140# options in the order they appear in the packet:
141#
142# N	   - NOP option
143# Wnnn	   - window scaling option, value nnn (or * or %nnn)
144# Mnnn	   - maximum segment size option, value nnn (or * or %nnn)
145# S	   - selective ACK OK
146# T	   - timestamp
147# T0	   - timestamp with a zero value
148#
149# To denote no TCP options, use a single '.'.
150#

160# WARNING WARNING WARNING
161# -----------------------
162#
163# Do not add a system X as OS Y just because NMAP says so. It is often
164# the case that X is a NAT firewall. While nmap is talking to the
165# device itself, p0f is fingerprinting the guy behind the firewall
166# instead.
167#
168# When in doubt, use common sense, don't add something that looks like
169# a completely different system as Linux or FreeBSD or LinkSys router.
170# Check DNS name, establish a connection to the remote host and look
171# at SYN+ACK - does it look similar?
172#
173# Some users tweak their TCP/IP settings - enable or disable RFC1323
174# functionality, enable or disable timestamps or selective ACK,
175# disable PMTU discovery, change MTU and so on. Always compare a new rule
176# to other fingerprints for this system, and verify the system isn't
177# "customized" before adding it. It is OK to add signature variants
178# caused by a commonly used software (personal firewalls, security
179# packages, etc), but it makes no sense to try to add every single
180# possible /proc/sys/net/ipv4 tweak on Linux or so.
181#
182# KEEP IN MIND: Some packet firewalls configured to normalize outgoing
183# traffic (OpenBSD pf with "scrub" enabled, for example) will, well,
184# normalize packets. Signatures will not correspond to the originating
185# system (and probably not quite to the firewall either).
186#
187# NOTE: Try to keep this file in some reasonable order, from most to
188# least likely systems. This will speed up operation. Also keep most
189# generic and broad rules near the end.
