#

#

# This fingerprint database is adapted from Michal Zalewski's p0f passive

# operating system package.  The last database sync was from a Nov 3 2003

# p0f.fp.

#

#

# 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 literally. 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.
