NAME
       openvas-nvt-sync	- updates the OpenVAS security checks from OpenVAS NVT
       Feed

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 either restart openvas-scanner(8) or send a SIGHUP	to its
       main process so that it loads the new checks and	uses them for new  se-
       curity 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.
