When running Lynis for the first time, run: lynis audit system --quick
audit Performs a system audit, which is the most common audit.
For more scan modes, see the helper utilities.
--auditor <full name> Define the name of the auditor/pen-tester. When a full name is used, add double quotes, like "Your Name". --checkall (or -c) Lynis performs a full check of the system, printing out the results of each test to stdout. Additional information will be saved into a log file (default is /var/log/lynis.log). This option invokes scan mode "audit system". In case the outcome of a scan needs to be automated, use the report file. --config Show which settings file or profile is being used, then quit. --cronjob Perform automatic scan with cron safe options (no colors, no questions, no breaks). --debug Display debug information to screen for troubleshooting purposes. --dump-options Show all available parameters. --logfile </path/to/logfile> Defines location and name of log file, instead of default /var/log/lynis.log. --no-colors Do not use colors for messages, warnings and sections. --no-log Redirect all logging information to /dev/null, prevent sensitive information to be written to disk. --pentest Run a non-privileged scan, usually for penetration testing. Some of the tests will be skipped if they require root permissions. --plugin-dir </path/to/plugins> Define location where plugins can be found. --profile </path/to/profile> Provide alternative profile to perform the scan. --quick (-Q) Do a quick scan (dont wait for user input). --quiet (-q) Try to run as silent as possible, showing only warnings. This option activates --quick as well. --report-file </path/to/report> Provide an alternative name for report file. --reverse-colors Optimize screen output for light backgrounds. --tests TEST-IDs Only run the specific test(s). When using multiple tests, add quotes around the line. --tests-category <category> Only perform tests from particular tests. Use --view-categories to determine valid options. --upload Upload data to Lynis Enterprise server. --view-categories Display all available test categories.
Multiple parameters are allowed, though some parameters can only be used together with others. When running Lynis without any parameters, help will be shown and the program will exit.
Lynis has special helpers to do certain tasks. This way the framework of Lynis is used, while at the same time storing most of the functionality in a separated file. This speeds up execution and keeps the code clean.
audit Run audit on the system or on other targets
update Run updater utility
To use a helper, run Lynis followed by the helper name.
Lynis uses exit codes to signal any invoking script. Currently the following codes are used:
0 Program exited normally, nothing found 1 Fatal error 64 An unknown parameter is used, or incomplete 65 Incorrect data encountered 66 Cant open file or directory 78 Lynis found 1 or more warnings or configurations errors
