NAME

       openvas-nasl - Nessus Attack Scripting Language

SYNOPSIS

       openvas-nasl <[-vh] [-T tracefile] [-s] [-t target] [-c config_file] [-d] [-sX] > files...

DESCRIPTION

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

OPTIONS

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

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

       -e iface
              Specifies  the  network  interface  to  be  used  as  the  source  for  established
              connections.

       -s     Sets the return value of safe_checks() to 1. (See the OpenVAS documentation to know
              what the safe checks are) Implies -B.

       -D     Only run the description part of the script.

       -B     Runs in description mode before running the script.

       -L     Lint the script  (run extended checks).

       -X     Run  the  script in authenticated mode. For more information see the nasl reference
              manual

       -h     Show help

       -v     Show the version of NASL.

       -d     Output debug information to stderr.

       -k key=value
              Set KB key to vaue. Can be used multiple times.

HISTORY

       NASL comes from a private project called 'pkt_forge', which was written in  late  1998  by
       Renaud  Deraison and which was an interactive shell to forge and send raw IP packets (this
       pre-dates Perl's Net::RawIP by a couple of weeks). It was then extended to do a wide range
       of network-related operations and integrated into Nessus as 'NASL'.

       The  parser was completely hand-written and a pain to work with. In Mid-2002, Michel Arboi
       wrote a bison parser for NASL, and he and Renaud  Deraison  re-wrote  NASL  from  scratch.
       Although the "new" NASL was nearly working as early as August 2002, Michel's lazyness made
       us wait for early 2003 to have it working completely.
