NAME
  ipscan, ipscan.conf -	ipscan file format

DESCRIPTION

  WARNING: This	feature	is to be considered experimental and may change	sig-
  nificantly until a final implementation is drawn up.

  The format for files accept by ipscan	currently follow this rough grammar:

  line	   ::= name ":"	matchup	[ "," matchup ]	"=" action .
  matchup  ::= "(" ")" | "(" literal ")" | "(" literal "," match ")" .
  action   ::= result |	result "else" result .
  result   ::= "close" | "track" | redirect .
  redirect ::= "redirect" ip-address [ "(" "," port-number ")" ] .
  match	   ::= { match-char }
  match-char ::= "*" | "?" | "."

  In this example an ip-address	is a dotted-quad IPv4 address and a port-
  number is a number betwee 1 and 65535, inclusive.  The match string is must
  be of	same length as the literal string that it is matching (literal).  The
  length of either string is limited to	16 bytes.

  Currently, the redirect option is not	yet been implemented.

  #
  # * =	match any character, . = exact match, ?	= case insensitive
  #
  # Scan for anything that looks like HTTP and redirect	it to the local
  # proxy.  One	catch -	this feature (redirect)	is not yet implemented.
  #
  http : ("GET ", "???." ) = redirect(127.0.0.1)
  #
  # Track ssh connections (i.e do nothing)
  #
  ssh :	(), ("SSH-") = track
  #
  # Things which look like smtp	to be tracked else closed.
  # Client can start with EHLO (ESMTP) or HELO (SMTP).
  #
  smtp : ("HELO	", "**??."), ("220 ", "....") =	track else close
  #
