NAME

6       openvas-nvt-sync - updates the OpenVAS security checks from OpenVAS NVT

SYNOPSIS

10       openvas-nvt-sync
11

DESCRIPTION

13       The OpenVAS Security Scanner performs several security checks, each  of
14       them  being  coded as an external plugin coded in NASL. As new security
15       holes are published every day, new plugins appear on the  OpenVAS  site
16       (www.openvas.org)
17       The  script  openvas-nvt-sync will fetch all the newest security checks
18       for you and install them at the proper location. Once this is done  you
19       will  need to restart openvas-scanner(8) so that it loads them and uses
20       them for new security scans.
21
22       openvas-nvt-sync uses rsync(1) and  md5sum(1) to do its job.  In  order
23       to  download the new plugins the machine where the script runs needs to
24       have access to rsync.openvas.org using the rsync protocol (TCP/UDP port
25       873).
26
27       If you are behind a web proxy you can configure rsync to use it through
28       the use of the RSYNC_PROXY environment variable. For  more  information
29       see rsync(1).

SECURITY NOTES

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