DESCRIPTION

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

20       -T tracefile
21              Makes nasl write verbosely what the  script  does  in  the  file
22              tracefile , ala 'set -x' under sh

25       -t target
26              Apply  the  NASL  script  to  target  which may be a single host
27              (127.0.0.1), a whole subnet (192.168.1.0/24) or several  subnets
28              (192.168.1.0/24, 192.168.243.0/24)

HISTORY

68       NASL comes from a private project called 'pkt_forge', which was written
69       in  late  1998 by Renaud Deraison and which was an interactive shell to
70       forge and send raw IP packets (this pre-dates Perl's  Net::RawIP  by  a
71       couple  of  weeks). It was then extended to do a wide range of network-
72       related operations and integrated into Nessus as 'NASL'.
73
74       The parser was completely hand-written and a  pain  to  work  with.  In
75       Mid-2002, Michel Arboi wrote a bison parser for NASL, and he and Renaud
76       Deraison re-wrote NASL from scratch. Although the "new" NASL was nearly
77       working  as  early  as  August 2002, Michel's laziness made us wait for
78       early 2003 to have it working completely.
