The last database sync was from a Nov 3 2003 26# p0f.fp. 27# 28# 29# Each line in this file specifies a single fingerprint. Please read the 30# information below carefully before attempting to append any signatures 31# reported as UNKNOWN to this file to avoid mistakes. 32# 33# We use the following set metrics for fingerprinting: 34# 35# - Window size (WSS) - a highly OS dependent setting used for TCP/IP 36# performance control (max. amount of data to be sent without ACK). 37# Some systems use a fixed value for initial packets. On other 38# systems, it is a multiple of MSS or MTU (MSS+40). In some rare 39# cases, the value is just arbitrary. 40# 41# NEW SIGNATURE: if p0f reported a special value of 'Snn', the number 42# appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn' 43# means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the 44# value of nn is not fixed (unlikely), just copy the Snn or Tnn token 45# literally. If you know this device has a simple stack and a fixed 46# MTU, you can however multiply S value by MSS, or T value by MSS+40, 47# and put it instead of Snn or Tnn. 48# 49# If WSS otherwise looks like a fixed value (for example a multiple 50# of two), or if you can confirm the value is fixed, please quote 51# it literally. If there's no apparent pattern in WSS chosen, you 52# should consider wildcarding this value. 53# 54# - Overall packet size - a function of all IP and TCP options and bugs. 55# 56# NEW SIGNATURE: Copy this value literally. 57# 58# - Initial TTL - We check the actual TTL of a received packet. It can't 59# be higher than the initial TTL, and also shouldn't be dramatically 60# lower (maximum distance is defined as 40 hops). 61# 62# NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally. 63# You need to determine the initial TTL. The best way to do it is to 64# check the documentation for a remote system, or check its settings. 65# A fairly good method is to simply round the observed TTL up to 66# 32, 64, 128, or 255, but it should be noted that some obscure devices 67# might not use round TTLs (in particular, some shoddy appliances use 68# "original" initial TTL settings). If not sure, you can see how many 69# hops you're away from the remote party with traceroute or mtr. 70# 71# - Don't fragment flag (DF) - some modern OSes set this to implement PMTU 72# discovery. Others do not bother. 73# 74# NEW SIGNATURE: Copy this value literally. 75# 76# - Maximum segment size (MSS) - this setting is usually link-dependent. P0f 77# uses it to determine link type of the remote host. 78# 79# NEW SIGNATURE: Always wildcard this value, except for rare cases when 80# you have an appliance with a fixed value, know the system supports only 81# a very limited number of network interface types, or know the system 82# is using a value it pulled out of nowhere. Specific unique MSS 83# can be used to tell Google crawlbots from the rest of the population. 84# 85# - Window scaling (WSCALE) - this feature is used to scale WSS. 86# It extends the size of a TCP/IP window to 32 bits. Some modern 87# systems implement this feature. 88# 89# NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set 90# to zero or other low value. There's usually no need to wildcard this 91# parameter. 92# 93# - Timestamp - some systems that implement timestamps set them to 94# zero in the initial SYN. This case is detected and handled appropriately. 95# 96# - Selective ACK permitted - a flag set by systems that implement 97# selective ACK functionality. 98# 99# - The sequence of TCP all options (MSS, window scaling, selective ACK 100# permitted, timestamp, NOP). Other than the options previously 101# discussed, p0f also checks for timestamp option (a silly 102# extension to broadcast your uptime ;-), NOP options (used for 103# header padding) and sackOK option (selective ACK feature). 104# 105# NEW SIGNATURE: Copy the sequence literally. 106# 107# To wildcard any value (except for initial TTL or TCP options), replace 108# it with '*'. You can also use a modulo operator to match any values 109# that divide by nnn - '%nnn'. 110# 111# Fingerprint entry format: 112# 113# wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details 114# 115# wwww - window size (can be *, %nnn, Snn or Tnn). The special values 116# "S" and "T" which are a multiple of MSS or a multiple of MTU 117# respectively. 118# ttt - initial TTL 119# D - don't fragment bit (0 - not set, 1 - set) 120# ss - overall SYN packet size 121# OOO - option value and order specification (see below) 122# OS - OS genre (Linux, Solaris, Windows) 123# Version - OS Version (2.0.27 on x86, etc) 124# Subtype - OS subtype or patchlevel (SP3, lo0) 125# details - Generic OS details 126# 127# If OS genre starts with '*', p0f will not show distance, link type 128# and timestamp data. It is useful for userland TCP/IP stacks of 129# network scanners and so on, where many settings are randomized or 130# bogus. 131# 132# If OS genre starts with @, it denotes an approximate hit for a group 133# of operating systems (signature reporting still enabled in this case). 134# Use this feature at the end of this file to catch cases for which 135# you don't have a precise match, but can tell it's Windows or FreeBSD 136# or whatnot by looking at, say, flag layout alone. 137# 138# Option block description is a list of comma or space separated 139# options in the order they appear in the packet: 140# 141# N - NOP option 142# Wnnn - window scaling option, value nnn (or * or %nnn) 143# Mnnn - maximum segment size option, value nnn (or * or %nnn) 144# S - selective ACK OK 145# T - timestamp 146# T0 - timestamp with a zero value 147# 148# To denote no TCP options, use a single '.'. 149# 150# Please report any additions to this file, or any inaccuracies or 151# problems spotted, to the maintainers: lcamtuf@coredump.cx, 152# frantzen@openbsd.org and bugs@openbsd.org with a tcpdump packet 153# capture of the relevant SYN packet(s) 154# 155# A test and submission page is available at 156# http://lcamtuf.coredump.cx/p0f-help/ 157# 158# 159# WARNING WARNING WARNING 160# ----------------------- 161# 162# Do not add a system X as OS Y just because NMAP says so. It is often 163# the case that X is a NAT firewall. While nmap is talking to the 164# device itself, p0f is fingerprinting the guy behind the firewall 165# instead. 166# 167# When in doubt, use common sense, don't add something that looks like 168# a completely different system as Linux or FreeBSD or LinkSys router. 169# Check DNS name, establish a connection to the remote host and look 170# at SYN+ACK - does it look similar? 171# 172# Some users tweak their TCP/IP settings - enable or disable RFC1323 173# functionality, enable or disable timestamps or selective ACK, 174# disable PMTU discovery, change MTU and so on. Always compare a new rule 175# to other fingerprints for this system, and verify the system isn't 176# "customized" before adding it. It is OK to add signature variants 177# caused by a commonly used software (personal firewalls, security 178# packages, etc), but it makes no sense to try to add every single 179# possible /proc/sys/net/ipv4 tweak on Linux or so. 180# 181# KEEP IN MIND: Some packet firewalls configured to normalize outgoing 182# traffic (OpenBSD pf with "scrub" enabled, for example) will, well, 183# normalize packets. Signatures will not correspond to the originating 184# system (and probably not quite to the firewall either). 185# 186# NOTE: Try to keep this file in some reasonable order, from most to 187# least likely systems. This will speed up operation. Also keep most 188# generic and broad rules near the end. 189# 190 191########################## 192# Standard OS signatures # 193########################## 194 195# ----------------- AIX --------------------- 196 197# AIX is first because its signatures are close to NetBSD, MacOS X and 198# Linux 2.0, but it uses a fairly rare MSSes, at least sometimes... 199# This is a shoddy hack, though. 200 20145046:64:0:44:M*: AIX:4.3::AIX 4.3 20216384:64:0:44:M512: AIX:4.3:2-3:AIX 4.3.2 and earlier 203 20416384:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 20516384:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 20632768:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 20732768:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 20865535:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 20965535:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 21065535:64:0:64:M*,N,W1,N,N,T,N,N,S: AIX:5.3:ML1:AIX 5.3 ML1 211 212# ----------------- Linux ------------------- 213 214# S1:64:0:44:M*:A: Linux:1.2::Linux 1.2.x (XXX quirks support) 215512:64:0:44:M*: Linux:2.0:3x:Linux 2.0.3x 21616384:64:0:44:M*: Linux:2.0:3x:Linux 2.0.3x 217 218# Endian snafu!
