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.

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).

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.
