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-server(8) s 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
       plugins.  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.
