SYNOPSISOpenVAS-Client [-v] [-h] [-n] [-T <type>] [-q [-pPS] host port user password targets results]
OpenVAS-Client -i in.nbe -o out.[html|xml|nbe]
DESCRIPTIONThe OpenVAS Security Scanner is a security auditing tool made up of two parts: a server, and a client. The server, openvasd is in charge of the attacks, whereas the client OpenVAS-Client provides an interface to the user.
OpenVAS-Client is an X11 client based on GTK+2.
This man page explains how to use the client.
- -c <config-file>, --config-file=<config-file>
use another configuration file.
- -n, --no-pixmaps
no pixmaps. This is handy if you are running OpenVAS-Client on a remote computer.
- -q, --batch-mode
quiet mode or batch mode. Setting this option makes OpenVAS-Client
expect all of the following settings.
obtain list of plugins installed on the server.
- obtain list of server and plugin preferences.
- issue SQL output for -p and -P (experimental).
- is the openvasd host to whom you will connect.
- is the port to which you will connect on the remote openvasd host.
- is the user name to use to connect to openvasd.
- is the password associated with this user name.
- is the name of a file containing the target machines.
- is the name of the file where the results will be stored at the end of the test.
- -T <type>, --output-type=<type>
Save the data as <type>, where <type> can be ``nbe'', ``html'',
``html_graph'', ``text'', ``xml'',
- -V, --verbose
make the batch mode display status messages to the screen.
- -x, --dont-check-ssl-cert
do not check SSL certificates.
- -v, --version
shows version number and quits
- -h, --help
lists the available options
The X11 interface
The OpenVAS-Client interface is divided in several panels:
- • The ``Openvasd host'' section:
In this section, you must enter the
host to whom you will connect, as well as the port. You must also enter your
user name and your password (not the one of the system). Once you are done, you
must click on the ``Log in'' button, which will establish the
connection to the
Once the connection is established, openvasd sends to the client the list of attacks it will perform, as well as the default preferences to use.
- • The ``Target Selection'' section:
• In this section, you are required to enter the primary target. A
may be a single host (e.g. x.y.test), an IP (e.g. 192.168.1.1), a
subnet (e.g. 192.168.1.1/24 or x.y.test), or a list of hosts,
separated by commas (e.g. 192.168.1.1, 192.168.2.1/24, x.y.test,
• You can restrict the maximum number of hosts to test using the ``Max Hosts'' entry. This is a feature that prevents you from scanning too many machines; or accidentally scanning other machines. (For instance, if you only plan to test x.y.info and a.b.info, you can safely set this entry to ``2'').
• This panel also allows you to enable the ``Perform a DNS zone transfer'' option. This option is dangerous and should be enabled with caution. For instance, if you want to test www.x.test, then if this option is set, openvasd will attempt to get the list of the hosts in the ``x.test'' domain.
This option may be dangerous. For instance, if you enable it and you ask to test 192.168.1.1/24, then openvasd will do a reverse lookup on every IP, and will attempt a DNS zone transfer on every domain. That is, if 192.168.1.1 is www.x.test, and 192.168.1.10 is mail.x.test, then a DNS zone transfer will be made on the domains ``x.test'' and ``test.x''.
- • The ``Plugins'' section
Once you have successfully logged into the remote
this section is filed with the list of the attacks that the server will
perform. This panel is divided in two parts: the plugins families, and
the plugins themselves. If you click on the name of a plugin, then
a dialog will appear, showing you which will be the error message
sent by the plugin if the attack is successful.
You can use OpenVAS-Client to do conversion between formats used for reports. OpenVAS can take any NBE reports and change them into HTML, XML or NBE reports.
Please note that the XML report provides usually more information about the scan itself NBE format do not include in the report.
Basically, XML is a merge between the .nbe reports and the .openvasrc configuration file. You won't get extra verbosity or diagnosis info in the XML report, but you'll know which plugins (and which version of these plugins) have been enabled during the scan.
For more information on the report formats please read the file nbe_file_format.txt provided along with the documentation.

To run a batch scan from a cron job and publish it in a given web space ( /var/www/html/openvas/ ) try the following:
OpenVAS-Client -c /root/openvas/openvas.rc -T html -qx localhost 9390 batch batch1 /root/openvas/target /var/www/html/openvas/results.html
Make sure that paranoia level is not set in your openvas.rc configuration file, otherwise the scan will not work
is the client configuration file, which contains the options about which
server to connect to, which plugins to activate, and so on. The file is
created automatically if it does not exist.
