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) # # A test and submission page is available at # http://lcamtuf.coredump.cx/p0f-help/ # # # 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. # ########################## # Standard OS signatures # ########################## # ----------------- AIX --------------------- # AIX is first because its signatures are close to NetBSD, MacOS X and # Linux 2.0, but it uses a fairly rare MSSes, at least sometimes... # This is a shoddy hack, though. 45046:64:0:44:M*: AIX:4.3::AIX 4.3 16384:64:0:44:M512: AIX:4.3:2-3:AIX 4.3.2 and earlier 16384:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 16384:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 32768:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 32768:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 65535:64:0:60:M512,N,W%2,N,N,T: AIX:4.3:3:AIX 4.3.3-5.2 65535:64:0:60:M512,N,W%2,N,N,T: AIX:5.1-5.2::AIX 4.3.3-5.2 65535:64:0:64:M*,N,W1,N,N,T,N,N,S: AIX:5.3:ML1:AIX 5.3 ML1 # ----------------- Linux ------------------- # S1:64:0:44:M*:A: Linux:1.2::Linux 1.2.x (XXX quirks support) 512:64:0:44:M*: Linux:2.0:3x:Linux 2.0.3x 16384:64:0:44:M*: Linux:2.0:3x:Linux 2.0.3x # Endian snafu!
