SYNOPSIS

DESCRIPTION

12       nasl executes a set of NASL scripts against a given target host. It can
13       also be used to determine if a NASL script has  any  syntax  errors  by
14       running it in parse (-p) or lint (-L) mode.

HISTORY

54       NASL comes from a private project called 'pkt_forge', which was written
55       in late 1998 by Renaud Deraison and which was an interactive  shell  to
56       forge  and  send  raw IP packets (this pre-dates Perl's Net::RawIP by a
57       couple of weeks). It was then extended to do a wide range  of  network-
58       related operations and integrated into Nessus as 'NASL'.
59
60       The  parser  was  completely  hand-written  and a pain to work with. In
61       Mid-2002, Michel Arboi wrote a bison parser for NASL, and he and Renaud
62       Deraison re-wrote NASL from scratch. Although the "new" NASL was nearly
63       working as early as August 2002, Michel's lazyness  made  us  wait  for
64       early 2003 to have it working completely.
