Please read the 29126756Smlaier# information below carefully before attempting to append any signatures 30126756Smlaier# reported as UNKNOWN to this file to avoid mistakes. 31126756Smlaier# 32126756Smlaier# We use the following set metrics for fingerprinting: 33126756Smlaier# 34126756Smlaier# - Window size (WSS) - a highly OS dependent setting used for TCP/IP 35126756Smlaier# performance control (max. amount of data to be sent without ACK). 36126756Smlaier# Some systems use a fixed value for initial packets. On other 37126756Smlaier# systems, it is a multiple of MSS or MTU (MSS+40). In some rare 38126756Smlaier# cases, the value is just arbitrary. 39126756Smlaier# 40126756Smlaier# NEW SIGNATURE: if p0f reported a special value of 'Snn', the number 41126756Smlaier# appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn' 42126756Smlaier# means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the 43126756Smlaier# value of nn is not fixed (unlikely), just copy the Snn or Tnn token 44126756Smlaier# literally. If you know this device has a simple stack and a fixed 45126756Smlaier# MTU, you can however multiply S value by MSS, or T value by MSS+40, 46126756Smlaier# and put it instead of Snn or Tnn. 47126756Smlaier# 48126756Smlaier# If WSS otherwise looks like a fixed value (for example a multiple 49126756Smlaier# of two), or if you can confirm the value is fixed, please quote 50126756Smlaier# it literally. If there's no apparent pattern in WSS chosen, you 51126756Smlaier# should consider wildcarding this value. 52126756Smlaier# 53126756Smlaier# - Overall packet size - a function of all IP and TCP options and bugs. 54126756Smlaier# 55126756Smlaier# NEW SIGNATURE: Copy this value literally. 56126756Smlaier# 57126756Smlaier# - Initial TTL - We check the actual TTL of a received packet. It can't 58126756Smlaier# be higher than the initial TTL, and also shouldn't be dramatically 59126756Smlaier# lower (maximum distance is defined as 40 hops). 60126756Smlaier# 61126756Smlaier# NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally. 62126756Smlaier# You need to determine the initial TTL. The best way to do it is to 63126756Smlaier# check the documentation for a remote system, or check its settings. 64126756Smlaier# A fairly good method is to simply round the observed TTL up to 65126756Smlaier# 32, 64, 128, or 255, but it should be noted that some obscure devices 66126756Smlaier# might not use round TTLs (in particular, some shoddy appliances use 67126756Smlaier# "original" initial TTL settings). If not sure, you can see how many 68126756Smlaier# hops you're away from the remote party with traceroute or mtr. 69126756Smlaier# 70126756Smlaier# - Don't fragment flag (DF) - some modern OSes set this to implement PMTU 71126756Smlaier# discovery. Others do not bother. 72126756Smlaier# 73126756Smlaier# NEW SIGNATURE: Copy this value literally. 74126756Smlaier# 75126756Smlaier# - Maximum segment size (MSS) - this setting is usually link-dependent. P0f 76126756Smlaier# uses it to determine link type of the remote host. 77126756Smlaier# 78126756Smlaier# NEW SIGNATURE: Always wildcard this value, except for rare cases when 79126756Smlaier# you have an appliance with a fixed value, know the system supports only 80126756Smlaier# a very limited number of network interface types, or know the system 81126756Smlaier# is using a value it pulled out of nowhere. Specific unique MSS 82126756Smlaier# can be used to tell Google crawlbots from the rest of the population. 83126756Smlaier# 84126756Smlaier# - Window scaling (WSCALE) - this feature is used to scale WSS. 85126756Smlaier# It extends the size of a TCP/IP window to 32 bits. Some modern 86126756Smlaier# systems implement this feature. 87126756Smlaier# 88126756Smlaier# NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set 89126756Smlaier# to zero or other low value. There's usually no need to wildcard this 90126756Smlaier# parameter. 91126756Smlaier# 92126756Smlaier# - Timestamp - some systems that implement timestamps set them to 93126756Smlaier# zero in the initial SYN. This case is detected and handled appropriately. 94126756Smlaier# 95126756Smlaier# - Selective ACK permitted - a flag set by systems that implement 96126756Smlaier# selective ACK functionality. 97126756Smlaier# 98126756Smlaier# - The sequence of TCP all options (MSS, window scaling, selective ACK 99126756Smlaier# permitted, timestamp, NOP). Other than the options previously 100126756Smlaier# discussed, p0f also checks for timestamp option (a silly 101126756Smlaier# extension to broadcast your uptime ;-), NOP options (used for 102126756Smlaier# header padding) and sackOK option (selective ACK feature). 103126756Smlaier# 104126756Smlaier# NEW SIGNATURE: Copy the sequence literally. 105126756Smlaier# 106126756Smlaier# To wildcard any value (except for initial TTL or TCP options), replace 107126756Smlaier# it with '*'. You can also use a modulo operator to match any values 108126756Smlaier# that divide by nnn - '%nnn'. 109126756Smlaier# 110126756Smlaier# Fingerprint entry format: 111126756Smlaier# 112126756Smlaier# wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details 113126756Smlaier# 114126756Smlaier# wwww - window size (can be *, %nnn, Snn or Tnn).

It is often 158126756Smlaier# the case that X is a NAT firewall. While nmap is talking to the 159126756Smlaier# device itself, p0f is fingerprinting the guy behind the firewall 160126756Smlaier# instead. 161126756Smlaier# 162126756Smlaier# When in doubt, use common sense, don't add something that looks like 163126756Smlaier# a completely different system as Linux or FreeBSD or LinkSys router. 164126756Smlaier# Check DNS name, establish a connection to the remote host and look 165126756Smlaier# at SYN+ACK - does it look similar? 166126756Smlaier# 167126756Smlaier# Some users tweak their TCP/IP settings - enable or disable RFC1323 168126756Smlaier# functionality, enable or disable timestamps or selective ACK, 169126756Smlaier# disable PMTU discovery, change MTU and so on. Always compare a new rule 170126756Smlaier# to other fingerprints for this system, and verify the system isn't 171126756Smlaier# "customized" before adding it. It is OK to add signature variants 172126756Smlaier# caused by a commonly used software (personal firewalls, security 173126756Smlaier# packages, etc), but it makes no sense to try to add every single 174126756Smlaier# possible /proc/sys/net/ipv4 tweak on Linux or so. 175126756Smlaier# 176126756Smlaier# KEEP IN MIND: Some packet firewalls configured to normalize outgoing 177126756Smlaier# traffic (OpenBSD pf with "scrub" enabled, for example) will, well, 178126756Smlaier# normalize packets. Signatures will not correspond to the originating 179126756Smlaier# system (and probably not quite to the firewall either). 180126756Smlaier# 181126756Smlaier# NOTE: Try to keep this file in some reasonable order, from most to 182126756Smlaier# least likely systems.
