The last database sync was from a Nov 3 2003 261.1Syamt# p0f.fp. 271.1Syamt# 281.1Syamt# 291.1Syamt# Each line in this file specifies a single fingerprint. Please read the 301.1Syamt# information below carefully before attempting to append any signatures 311.1Syamt# reported as UNKNOWN to this file to avoid mistakes. 321.1Syamt# 331.1Syamt# We use the following set metrics for fingerprinting: 341.1Syamt# 351.1Syamt# - Window size (WSS) - a highly OS dependent setting used for TCP/IP 361.1Syamt# performance control (max. amount of data to be sent without ACK). 371.1Syamt# Some systems use a fixed value for initial packets. On other 381.1Syamt# systems, it is a multiple of MSS or MTU (MSS+40). In some rare 391.1Syamt# cases, the value is just arbitrary. 401.1Syamt# 411.1Syamt# NEW SIGNATURE: if p0f reported a special value of 'Snn', the number 421.1Syamt# appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn' 431.1Syamt# means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the 441.1Syamt# value of nn is not fixed (unlikely), just copy the Snn or Tnn token 451.1Syamt# literally. If you know this device has a simple stack and a fixed 461.1Syamt# MTU, you can however multiply S value by MSS, or T value by MSS+40, 471.1Syamt# and put it instead of Snn or Tnn. 481.1Syamt# 491.1Syamt# If WSS otherwise looks like a fixed value (for example a multiple 501.1Syamt# of two), or if you can confirm the value is fixed, please quote 511.1Syamt# it literally. If there's no apparent pattern in WSS chosen, you 521.1Syamt# should consider wildcarding this value. 531.1Syamt# 541.1Syamt# - Overall packet size - a function of all IP and TCP options and bugs. 551.1Syamt# 561.1Syamt# NEW SIGNATURE: Copy this value literally. 571.1Syamt# 581.1Syamt# - Initial TTL - We check the actual TTL of a received packet. It can't 591.1Syamt# be higher than the initial TTL, and also shouldn't be dramatically 601.1Syamt# lower (maximum distance is defined as 40 hops). 611.1Syamt# 621.1Syamt# NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally. 631.1Syamt# You need to determine the initial TTL. The best way to do it is to 641.1Syamt# check the documentation for a remote system, or check its settings. 651.1Syamt# A fairly good method is to simply round the observed TTL up to 661.1Syamt# 32, 64, 128, or 255, but it should be noted that some obscure devices 671.1Syamt# might not use round TTLs (in particular, some shoddy appliances use 681.1Syamt# "original" initial TTL settings). If not sure, you can see how many 691.1Syamt# hops you're away from the remote party with traceroute or mtr. 701.1Syamt# 711.1Syamt# - Don't fragment flag (DF) - some modern OSes set this to implement PMTU 721.1Syamt# discovery. Others do not bother. 731.1Syamt# 741.1Syamt# NEW SIGNATURE: Copy this value literally. 751.1Syamt# 761.1Syamt# - Maximum segment size (MSS) - this setting is usually link-dependent. P0f 771.1Syamt# uses it to determine link type of the remote host. 781.1Syamt# 791.1Syamt# NEW SIGNATURE: Always wildcard this value, except for rare cases when 801.1Syamt# you have an appliance with a fixed value, know the system supports only 811.1Syamt# a very limited number of network interface types, or know the system 821.1Syamt# is using a value it pulled out of nowhere. Specific unique MSS 831.1Syamt# can be used to tell Google crawlbots from the rest of the population. 841.1Syamt# 851.1Syamt# - Window scaling (WSCALE) - this feature is used to scale WSS. 861.1Syamt# It extends the size of a TCP/IP window to 32 bits. Some modern 871.1Syamt# systems implement this feature. 881.1Syamt# 891.1Syamt# NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set 901.1Syamt# to zero or other low value. There's usually no need to wildcard this 911.1Syamt# parameter. 921.1Syamt# 931.1Syamt# - Timestamp - some systems that implement timestamps set them to 941.1Syamt# zero in the initial SYN. This case is detected and handled appropriately. 951.1Syamt# 961.1Syamt# - Selective ACK permitted - a flag set by systems that implement 971.1Syamt# selective ACK functionality. 981.1Syamt# 991.1Syamt# - The sequence of TCP all options (MSS, window scaling, selective ACK 1001.1Syamt# permitted, timestamp, NOP). Other than the options previously 1011.1Syamt# discussed, p0f also checks for timestamp option (a silly 1021.1Syamt# extension to broadcast your uptime ;-), NOP options (used for 1031.1Syamt# header padding) and sackOK option (selective ACK feature). 1041.1Syamt# 1051.1Syamt# NEW SIGNATURE: Copy the sequence literally. 1061.1Syamt# 1071.1Syamt# To wildcard any value (except for initial TTL or TCP options), replace 1081.1Syamt# it with '*'. You can also use a modulo operator to match any values 1091.1Syamt# that divide by nnn - '%nnn'. 1101.1Syamt# 1111.1Syamt# Fingerprint entry format: 1121.1Syamt# 1131.1Syamt# wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details 1141.1Syamt# 1151.1Syamt# wwww - window size (can be *, %nnn, Snn or Tnn). The special values 1161.1Syamt# "S" and "T" which are a multiple of MSS or a multiple of MTU 1171.1Syamt# respectively. 1181.1Syamt# ttt - initial TTL 1191.1Syamt# D - don't fragment bit (0 - not set, 1 - set) 1201.1Syamt# ss - overall SYN packet size 1211.1Syamt# OOO - option value and order specification (see below) 1221.1Syamt# OS - OS genre (Linux, Solaris, Windows) 1231.1Syamt# Version - OS Version (2.0.27 on x86, etc) 1241.1Syamt# Subtype - OS subtype or patchlevel (SP3, lo0) 1251.1Syamt# details - Generic OS details 1261.1Syamt# 1271.1Syamt# If OS genre starts with '*', p0f will not show distance, link type 1281.1Syamt# and timestamp data. It is useful for userland TCP/IP stacks of 1291.1Syamt# network scanners and so on, where many settings are randomized or 1301.1Syamt# bogus. 1311.1Syamt# 1321.1Syamt# If OS genre starts with @, it denotes an approximate hit for a group 1331.1Syamt# of operating systems (signature reporting still enabled in this case). 1341.1Syamt# Use this feature at the end of this file to catch cases for which 1351.1Syamt# you don't have a precise match, but can tell it's Windows or FreeBSD 1361.1Syamt# or whatnot by looking at, say, flag layout alone. 1371.1Syamt# 1381.1Syamt# Option block description is a list of comma or space separated 1391.1Syamt# options in the order they appear in the packet: 1401.1Syamt# 1411.1Syamt# N - NOP option 1421.1Syamt# Wnnn - window scaling option, value nnn (or * or %nnn) 1431.1Syamt# Mnnn - maximum segment size option, value nnn (or * or %nnn) 1441.1Syamt# S - selective ACK OK 1451.1Syamt# T - timestamp 1461.1Syamt# T0 - timestamp with a zero value 1471.1Syamt# 1481.1Syamt# To denote no TCP options, use a single '.'. 1491.1Syamt# 1501.1Syamt# Please report any additions to this file, or any inaccuracies or 1511.1Syamt# problems spotted, to the maintainers: lcamtuf@coredump.cx, 1521.1Syamt# frantzen@openbsd.org and bugs@openbsd.org with a tcpdump packet 1531.1Syamt# capture of the relevant SYN packet(s) 1541.1Syamt# 1551.1Syamt# A test and submission page is available at 1561.1Syamt# http://lcamtuf.coredump.cx/p0f-help/ 1571.1Syamt# 1581.1Syamt# 1591.1Syamt# WARNING WARNING WARNING 1601.1Syamt# ----------------------- 1611.1Syamt# 1621.1Syamt# Do not add a system X as OS Y just because NMAP says so. It is often 1631.1Syamt# the case that X is a NAT firewall. While nmap is talking to the 1641.1Syamt# device itself, p0f is fingerprinting the guy behind the firewall 1651.1Syamt# instead. 1661.1Syamt# 1671.1Syamt# When in doubt, use common sense, don't add something that looks like 1681.1Syamt# a completely different system as Linux or FreeBSD or LinkSys router. 1691.1Syamt# Check DNS name, establish a connection to the remote host and look 1701.1Syamt# at SYN+ACK - does it look similar? 1711.1Syamt# 1721.1Syamt# Some users tweak their TCP/IP settings - enable or disable RFC1323 1731.1Syamt# functionality, enable or disable timestamps or selective ACK, 1741.1Syamt# disable PMTU discovery, change MTU and so on. Always compare a new rule 1751.1Syamt# to other fingerprints for this system, and verify the system isn't 1761.1Syamt# "customized" before adding it. It is OK to add signature variants 1771.1Syamt# caused by a commonly used software (personal firewalls, security 1781.1Syamt# packages, etc), but it makes no sense to try to add every single 1791.1Syamt# possible /proc/sys/net/ipv4 tweak on Linux or so. 1801.1Syamt# 1811.1Syamt# KEEP IN MIND: Some packet firewalls configured to normalize outgoing 1821.1Syamt# traffic (OpenBSD pf with "scrub" enabled, for example) will, well, 1831.1Syamt# normalize packets. Signatures will not correspond to the originating 1841.1Syamt# system (and probably not quite to the firewall either). 1851.1Syamt# 1861.1Syamt# NOTE: Try to keep this file in some reasonable order, from most to 1871.1Syamt# least likely systems. This will speed up operation. Also keep most 1881.1Syamt# generic and broad rules near the end. 1891.1Syamt# 1901.1Syamt 1911.1Syamt########################## 1921.1Syamt# Standard OS signatures # 1931.1Syamt########################## 1941.1Syamt 1951.1Syamt# ----------------- AIX --------------------- 1961.1Syamt 1971.1Syamt# AIX is first because its signatures are close to NetBSD, MacOS X and 1981.1Syamt# Linux 2.0, but it uses a fairly rare MSSes, at least sometimes... 1991.1Syamt# This is a shoddy hack, though. 2001.1Syamt 2011.1Syamt45046:64:0:44:M*: AIX:4.3::AIX 4.3 2021.1Syamt16384:64:0:44:M512: AIX:4.3:2-3:AIX 4.3.2 and earlier 2031.1Syamt 2041.1Syamt16384:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 2051.1Syamt16384:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 2061.1Syamt32768:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 2071.1Syamt32768:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 2081.1Syamt65535:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 2091.1Syamt65535:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 2101.1Syamt65535:64:0:64:M*,N,W1,N,N,T,N,N,S: AIX:5.3:ML1:AIX 5.3 ML1 2111.1Syamt 2121.1Syamt# ----------------- Linux ------------------- 2131.1Syamt 2141.1Syamt# S1:64:0:44:M*:A: Linux:1.2::Linux 1.2.x (XXX quirks support) 2151.1Syamt512:64:0:44:M*: Linux:2.0:3x:Linux 2.0.3x 2161.1Syamt16384:64:0:44:M*: Linux:2.0:3x:Linux 2.0.3x 2171.1Syamt 2181.1Syamt# Endian snafu!
