This flag causes the Nessus GUI GTK client to load without pixmaps. This is handy when running Nessus on a remote computer over an exported X11 session.

Quiet mode or batch mode. This option causes the Nessus client to run from the command-line only (no GUI). This enables Nessus scans to be performed non-interactively from the command-line, cron, or otherwise.

Specify the client-side Nessus configuration file (.nessusrc) to use. This option is only used when starting the "nessus" client.

This option is used with the Nessusd server. Make Nessusd display its version number and exit.

The Nessus GTK GUI can open a report file from a previous scan and display the report.

This option is used when starting the Nessusd server. Make the server display its compilation options.

Causes the Nessus client to display its version number then exit.

This option is used with the Nessusd server. Make the server display a summary of the commands and exit.

This option forces the Nessus client to not check the Nessus server's SSL certificate when connecting.

Causes the Nessus client to display a help message, then exit.

Uses the Nessus client to obtain the list of server and plugin preferences from the Nessus server.

Causes the Nessus client to generate SQL syntax for the output of the '-p' (show plugins on the server) and '-P' (show server/plugin preferences) commands.

Define what format should be used for the report data from a scan. Options are: nbe, html, html_graph, text, xml, old-xml, tex, or nsr.

Uses the Nessus client to obtain the list of plugins available on the Nessus server.

This option is used when starting the Nessusd server. Force the source IP of the connections established by Nessusd during scanning to . This option is only useful if you have a multi-homed machine with multiple public IP addresses that you would like to use instead of the default one. Example: nessusd -S 192.168.1.1,192.168.1.2,192.168.1.3,192.168.1.4 ...will make nessusd establish connections with a source IP of one among those listed above. For this setup to work, the host running nessusd should have multiple NICs with these IP addresses set.

This option is used when starting the Nessusd server. Tell the server to listen for client connections on the port rather than listening on port 1241/tcp (default).

This option is used when starting the Nessusd server. Make the server run in background (daemon mode).

This option is used when starting the Nessusd server. Tell the server to only listen to connections on the address

which is an IP, not a machine name. For instance, "nessusd -a 192.168.1.1" will make nessusd only listen to client connection requests going to 192.168.1.1 This option is useful if you are running nessusd on a gateway and if you don't want people on the outside to connect to your nessusd server. By default, if the "-a" option is not used, Nessusd will listen on all active interfaces.

Specify the output file for the Nessus client to create when converting between two report formats. You can use nessus to do conversion between formats used for reports. Nessus can take any NSR or NBE reports and change them into HTML, XML, NSR or NBE reports. Please note that the XML report usually provides more information about the scan than the NSR or NBE formats include in the report. Basically, XML is a merge between the .nbe reports and the .nessusrc 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 files nsr_file_format.txt and nbe_file_format.txt provided along with the documentation.

Specify the server-side Nessusd configuration file (nessusd.conf) to use, instead of the standard /usr/local/etc/nessus/nessusd.conf. This option is only used when starting the "nessusd" server process.

When using the Nessus command-line client (the '-q' option), this option causes the client to display status messages to the screen.

Specify the input file for the Nessus client to read when converting between two report formats. You can use nessus to do conversion between formats used for reports.
