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

++ **
++ * 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."
