DESCRIPTION

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

HISTORY

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