NAME
       openvas-nvt-sync - updates the OpenVAS security checks

SYNOPSIS
       openvas-nvt-sync

DESCRIPTION
       The  OpenVAS Security Scanner performs several security checks, each of
       them being coded as an external plugin coded in NASL. As	 new  security
       holes  are  published every day, new plugins appear on the OpenVAS site
       (www.openvas.org)
       The script openvas-nvt-sync will fetch all the newest  security	checks
       for  you and install them at the proper location. Once this is done you
       will need to restart openvas-scanner(8) so that it loads them and  uses
       them for new security scans.

       openvas-nvt-sync	 uses  rsync(1) and  md5sum(1) to do its job. In order
       to download the new plugins the machine where the script runs needs  to
       have access to rsync.openvas.org using the rsync protocol (TCP/UDP port
       873).

       If you are behind a web proxy you can configure rsync to use it through
       the  use	 of the RSYNC_PROXY environment variable. For more information
       see rsync(1).

SECURITY NOTES
       openvas-nvt-sync uses rsync(1) to retrieve the archive of the new plug‐
       ins.  The  scripts provided by the OpenVAS project might not be signed.
       Consequently, if somewhere where to poison your DNS  server  and	 force
       this  script  to	 retrieve  NASL plugins on another site he would force
       your OpenVAS server to  execute	NASL  scripts  when  running  security
       tests.	Even  if  this	might not do much harm (see the NASL reference
       guide for more information on that subject) you should be very  careful
       when doing this.

       on Debian systems.
