# passive OS fingerprinting
# -------------------------
#
# SYN signatures. Those signatures work for SYN packets only (duh!).

# ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF
# OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE.
#
#
# This fingerprint database is adapted from Michal Zalewski's p0f passive
# operating system package.
#
#
# Each line in this file specifies a single fingerprint. Please read the
# information below carefully before attempting to append any signatures
# reported as UNKNOWN to this file to avoid mistakes.
#
# We use the following set metrics for fingerprinting:
#
# - Window size (WSS) - a highly OS dependent setting used for TCP/IP
# performance control (max. amount of data to be sent without ACK).
# Some systems use a fixed value for initial packets. On other
# systems, it is a multiple of MSS or MTU (MSS+40). In some rare
# cases, the value is just arbitrary.
#
# NEW SIGNATURE: if p0f reported a special value of 'Snn', the number
# appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
# means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the
# value of nn is not fixed (unlikely), just copy the Snn or Tnn token
# literally. If you know this device has a simple stack and a fixed
# MTU, you can however multiply S value by MSS, or T value by MSS+40,
# and put it instead of Snn or Tnn.
#
# If WSS otherwise looks like a fixed value (for example a multiple
# of two), or if you can confirm the value is fixed, please quote
# it literaly. If there's no apparent pattern in WSS chosen, you
# should consider wildcarding this value.
#
# - Overall packet size - a function of all IP and TCP options and bugs.
#
# NEW SIGNATURE: Copy this value literally.
#
# - Initial TTL - We check the actual TTL of a received packet. It can't
# be higher than the initial TTL, and also shouldn't be dramatically
# lower (maximum distance is defined as 40 hops).
#
# NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally.
# You need to determine the initial TTL. The best way to do it is to
# check the documentation for a remote system, or check its settings.
# A fairly good method is to simply round the observed TTL up to
# 32, 64, 128, or 255, but it should be noted that some obscure devices
# might not use round TTLs (in particular, some shoddy appliances use
# "original" initial TTL settings). If not sure, you can see how many
# hops you're away from the remote party with traceroute or mtr.
#
# - Don't fragment flag (DF) - some modern OSes set this to implement PMTU
# discovery. Others do not bother.
#
# NEW SIGNATURE: Copy this value literally.
#
# - Maximum segment size (MSS) - this setting is usually link-dependent. P0f
# uses it to determine link type of the remote host.
#
# NEW SIGNATURE: Always wildcard this value, except for rare cases when
# you have an appliance with a fixed value, know the system supports only
# a very limited number of network interface types, or know the system
# is using a value it pulled out of nowhere. Specific unique MSS
# can be used to tell Google crawlbots from the rest of the population.
#
# - Window scaling (WSCALE) - this feature is used to scale WSS.
# It extends the size of a TCP/IP window to 32 bits. Some modern
# systems implement this feature.
#
# NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set
# to zero or other low value. There's usually no need to wildcard this
# parameter.
#
# - Timestamp - some systems that implement timestamps set them to
# zero in the initial SYN. This case is detected and handled appropriately.
#
# - Selective ACK permitted - a flag set by systems that implement
# selective ACK functionality.
#
# - The sequence of TCP all options (MSS, window scaling, selective ACK
# permitted, timestamp, NOP). Other than the options previously
# discussed, p0f also checks for timestamp option (a silly
# extension to broadcast your uptime ;-), NOP options (used for
# header padding) and sackOK option (selective ACK feature).
#
# NEW SIGNATURE: Copy the sequence literally.
#
# To wildcard any value (except for initial TTL or TCP options), replace
# it with '*'. You can also use a modulo operator to match any values
# that divide by nnn - '%nnn'.
#
# Fingerprint entry format:
#
# wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details
#
# wwww - window size (can be *, %nnn, Snn or Tnn). The special values
# "S" and "T" which are a multiple of MSS or a multiple of MTU
# respectively.
# ttt - initial TTL
# D - don't fragment bit (0 - not set, 1 - set)
# ss - overall SYN packet size
# OOO - option value and order specification (see below)
# OS - OS genre (Linux, Solaris, Windows)
# Version - OS Version (2.0.27 on x86, etc)
# Subtype - OS subtype or patchlevel (SP3, lo0)
# details - Generic OS details
#
# If OS genre starts with '*', p0f will not show distance, link type
# and timestamp data. It is useful for userland TCP/IP stacks of
# network scanners and so on, where many settings are randomized or
# bogus.
#
# If OS genre starts with @, it denotes an approximate hit for a group
# of operating systems (signature reporting still enabled in this case).
# Use this feature at the end of this file to catch cases for which
# you don't have a precise match, but can tell it's Windows or FreeBSD
# or whatnot by looking at, say, flag layout alone.
#
# Option block description is a list of comma or space separated
# options in the order they appear in the packet:
#
# N - NOP option
# Wnnn - window scaling option, value nnn (or * or %nnn)
# Mnnn - maximum segment size option, value nnn (or * or %nnn)
# S - selective ACK OK
# T - timestamp
# T0 - timestamp with a zero value
#
# To denote no TCP options, use a single '.'.
#
# Please report any additions to this file, or any inaccuracies or
# problems spotted, to the maintainers: lcamtuf@coredump.cx,
# frantzen@openbsd.org and bugs@openbsd.org with a tcpdump packet
# capture of the relevant SYN packet(s)
#
# WARNING WARNING WARNING
# -----------------------
#
# Do not add a system X as OS Y just because NMAP says so. It is often
# the case that X is a NAT firewall. While nmap is talking to the
# device itself, p0f is fingerprinting the guy behind the firewall
# instead.
#
# When in doubt, use common sense, don't add something that looks like
# a completely different system as Linux or FreeBSD or LinkSys router.
# Check DNS name, establish a connection to the remote host and look
# at SYN+ACK - does it look similar?
#
# Some users tweak their TCP/IP settings - enable or disable RFC1323
# functionality, enable or disable timestamps or selective ACK,
# disable PMTU discovery, change MTU and so on. Always compare a new rule
# to other fingerprints for this system, and verify the system isn't
# "customized" before adding it. It is OK to add signature variants
# caused by a commonly used software (personal firewalls, security
# packages, etc), but it makes no sense to try to add every single
# possible /proc/sys/net/ipv4 tweak on Linux or so.
#
# KEEP IN MIND: Some packet firewalls configured to normalize outgoing
# traffic (OpenBSD pf with "scrub" enabled, for example) will, well,
# normalize packets. Signatures will not correspond to the originating
# system (and probably not quite to the firewall either).
#
# NOTE: Try to keep this file in some reasonable order, from most to
# least likely systems. This will speed up operation. Also keep most
# generic and broad rules near the end.
