--Account traffic for all hosts in defined network/netmask.
--
--Features:
--
--- long (one counter per protocol TCP/UDP/IMCP/Other) and short statistics
--
--- one iptables rule for all hosts in network/netmask
--
--- loading/saving counters (by reading/writting to procfs entries)
--
--.TP
--.BI "--aaddr " "network/netmask"
--defines network/netmask for which make statistics.
--.TP
--.BI "--aname " "name"
--defines name of list where statistics will be kept. If no is
--specified DEFAULT will be used.
--.TP
--.B "--ashort"
--table will colect only short statistics (only total counters
--without splitting it into protocols.
--.P
--Example usage:
--
--account traffic for/to 192.168.0.0/24 network into table mynetwork:
--
--# iptables -A FORWARD -m account --aname mynetwork --aaddr 192.168.0.0/24
--
--account traffic for/to WWW serwer for 192.168.0.0/24 network into table mywwwserver:
--
--# iptables -A INPUT -p tcp --dport 80
-- -m account --aname mywwwserver --aaddr 192.168.0.0/24 --ashort
--
--# iptables -A OUTPUT -p tcp --sport 80
-- -m account --aname mywwwserver --aaddr 192.168.0.0/24 --ashort
--
--read counters:
--
--# cat /proc/net/ipt_account/mynetwork
--# cat /proc/net/ipt_account/mywwwserver
--
--set counters:
--
--# echo "ip = 192.168.0.1 packets_src = 0" > /proc/net/ipt_account/mywwserver

--The idea of passive OS fingerprint matching exists for quite a long time,
--but was created as extension fo OpenBSD pf only some weeks ago.
--Original idea was lurked in some OpenBSD mailing list (thanks
--grange@open...) and than adopted for Linux netfilter in form of this code.
--
--Original fingerprint table was created by Michal Zalewski <lcamtuf@coredump.cx>.
--
--This module compares some data(WS, MSS, options and it's order, ttl,
--df and others) from first SYN packet (actually from packets with SYN
--bit set) with dynamically loaded OS fingerprints.
--.TP
--.B "--log 1/0"
--If present, OSF will log determined genres even if they don't match
--desired one.
--0 - log all determined entries,
--1 - only first one.
--
--In syslog you find something like this:
--.IP
--ipt_osf: Windows [2000:SP3:Windows XP Pro SP1, 2000 SP3]: 11.22.33.55:4024 -> 11.22.33.44:139
--.IP
--ipt_osf: Unknown: 16384:106:1:48:020405B401010402 44.33.22.11:1239 -> 11.22.33.44:80
--.TP
--.B "--smart"
--if present, OSF will use some smartness to determine remote OS.
--OSF will use initial TTL only if source of connection is in our local network.
--.TP
--.B "--netlink"
--If present, OSF will log all events also through netlink NETLINK_NFLOG groupt 1.
--.TP
--.BI "--genre " "[!] string"
--Match a OS genre by passive fingerprinting
--.P
--Example:
--
--#iptables -I INPUT -j ACCEPT -p tcp -m osf --genre Linux --log 1 --smart
--
--NOTE: -p tcp is obviously required as it is a TCP match.
--
--Fingerprints can be loaded and read through /proc/sys/net/ipv4/osf file.
--One can flush all fingerprints with following command:
--.IP
--echo -en FLUSH > /proc/sys/net/ipv4/osf
--.P
--Only one fingerprint per open/write/close.
--
--Fingerprints can be downloaded from http://www.openbsd.org/cgi-bin/cvsweb/src/etc/pf.os

--/* RPC extension for IP connection matching, Version 2.2
-- * (C) 2000 by Marcelo Barbosa Lima <marcelo.lima@dcc.unicamp.br>
-- * - original rpc tracking module
-- * - "recent" connection handling for kernel 2.3+ netfilter
-- *
-- * (C) 2001 by Rusty Russell <rusty@rustcorp.com.au>
-- * - upgraded conntrack modules to oldnat api - kernel 2.4.0+
-- *
-- * (C) 2002,2003 by Ian (Larry) Latter <Ian.Latter@mq.edu.au>
-- * - upgraded conntrack modules to newnat api - kernel 2.4.20+

-- * Userspace library syntax:
-- * --rpc [--rpcs procedure1,procedure2,...procedure128] [--static]
-- *
-- * Procedures can be supplied in either numeric or named formats.
-- * Without --rpcs, this module will behave as the old record-rpc.
-- **
-- * Note to all:
-- *
-- * RPCs should not be exposed to the internet - ask the Pentagon;
-- *
-- * "The unidentified crackers pleaded guilty in July to charges
-- * of juvenile delinquency stemming from a string of Pentagon
-- * network intrusions in February.
-- *
-- * The youths, going by the names TooShort and Makaveli, used
-- * a common server security hole to break in, according to
-- * Dane Jasper, owner of the California Internet service
-- * provider, Sonic. They used the hole, known as the 'statd'
-- * exploit, to attempt more than 800 break-ins, Jasper said."

--This offers similar functionality to LaBrea
