|
[+] General
|
|
-------------------------------
|
|
|
|
Q: I don't understand the program (output), what to do?
|
|
A: Keep reading this FAQ. Also useful are the README file and the log file
|
|
(default: /var/log/lynis.log). Or check out the documentation on the
|
|
website: https://cisofy.com/support/
|
|
|
|
Q: I can't find any configuration file for Lynis, where is it?
|
|
A: Lynis uses profiles. A profile is similar to a configuration file and
|
|
determines how a security scan should be performed. Profiles are usually
|
|
stored in /etc/lynis or can be found using 'lynis show profiles'.
|
|
|
|
Q: My version is outdated, what can I do to upgrade?
|
|
Check out the upgrade guide: https://cisofy.com/documentation/lynis/upgrading/
|
|
|
|
Q: Why is there no port/package for my operating system?
|
|
A: Because there is no maintainer for it yet. If you have the time to keep
|
|
the port/package current for your preferred operating system, let us know.
|
|
|
|
Q: What to do with the report files?
|
|
A: The output could be used for monitoring (baseline checks). For users of the
|
|
Lynis Enterprise Suite, they will be used to upload data.
|
|
|
|
|
|
|
|
[+] Bugs or issues
|
|
-------------------------------
|
|
Q: Where can I report an issue or bug?
|
|
A: GitHub, or use the developer e-mail address lynis-dev@cisofy.com
|
|
|
|
|
|
|
|
[+] Usage problems
|
|
-------------------------------
|
|
Q: Lynis hangs while testing the group files (grpck)
|
|
A: Run the grpck command manually. It will most likely need user input, to
|
|
repair incorrect groups.
|
|
|
|
Q: Lynis doesn't display all messages on a white background
|
|
A: White text is used for general (and important) messages. Most terminals
|
|
have a dark background, so it gives extra attention to the message. However
|
|
if you have a white background (for example Mac OS X), you can run Lynis
|
|
with --no-colors to strip colors or --reverse-colors to reverse the color
|
|
scheme. Another option is to change your terminal colors within Mac OS.
|
|
|
|
Q: Some tests take very long to finish, what to do?
|
|
A: Use a second console (or connection) and check the output of ps/lsof etc,
|
|
to see the status of the active subroutine. If a specific test hangs for a
|
|
very long time, try to kill that specific process (ie grpck) and see if
|
|
Lynis continues. Afterwards, run the command manually to see the cause.
|
|
Check the log file for additional information. Usually the last few lines
|
|
will indicate what test is stuck.
|
|
|
|
Q: When running Lynis, it shows me the usage help even while using correct
|
|
parameters, why?
|
|
A: This can happen with alternative shells. Try using a different shell to
|
|
invoke Lynis (example: bash lynis audit system).
|
|
|
|
Q: One or more tests are giving incorrect output. How to solve that?
|
|
A: Check the log file. If that also has incorrect data, let us know via GitHub
|
|
or use the developer e-mail address.
|
|
|
|
Q: The program takes long to complete and also uses too much resources. Can it
|
|
be tuned?
|
|
A: The time it takes to complete depends on the amount of tests to run.
|
|
However the resources it take can be slightly lowered by increasing the
|
|
pause_between_tests profile option. Keep in mind this increases the total
|
|
length of the scan to complete.
|
|
|
|
|
|
|
|
[+] Network related issues
|
|
-------------------------------
|
|
|
|
Q: Lynis reports promiscuous interfaces, but they are needed for normal operation,
|
|
how can I hide this warning?
|
|
A: Whitelist the interface in the profile file (if_promisc).
