The last database sync was from a Nov 3 2003 25# p0f.fp. 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 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. 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 50# it literally. If there's no apparent pattern in WSS chosen, you 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 59# lower (maximum distance is defined as 40 hops). 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 86# systems implement this feature. 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# 95# - Selective ACK permitted - a flag set by systems that implement 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 107# it with '*'. You can also use a modulo operator to match any values 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. 117# ttt - initial TTL 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 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. 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 144# T - timestamp 145# T0 - timestamp with a zero value 146# 147# To denote no TCP options, use a single '.'. 148# 149# Please report any additions to this file, or any inaccuracies or 150# problems spotted, to the maintainers: lcamtuf@coredump.cx, 151# frantzen@openbsd.org and bugs@openbsd.org with a tcpdump packet 152# capture of the relevant SYN packet(s) 153# 154# A test and submission page is available at 155# http://lcamtuf.coredump.cx/p0f-help/ 156# 157# 158# WARNING WARNING WARNING 159# ----------------------- 160# 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 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.
