Sometimes, even with all the hard work done to prepare your setup, issues occur.
|
|
Generally it's always good to check your logs (:menuselection:`System --> Log Files` or the ones found in the module your trying to setup),
|
|
but sometimes more help is needed.
|
|
|
|
|
|
General issue workflow
|
|
...........................
|
|
|
|
Before reporting issues, please make sure yours still exists on the latest version.
|
|
We generally advice to check the existing `issues <https://github.com/opnsense/core/issues>`__ and our `forum <https://forum.opnsense.org/>`__
|
|
before reporting new ones.
|
|
|
|
In case your issue was introduced after a (minor) upgrade, you can use `opnsense-revert <https://docs.opnsense.org/manual/opnsense_tools.html#opnsense-revert>`__
|
|
to downgrade specific packages installed on the system.
|
|
|
|
Using the firmware section (:menuselection:`System --> Firmware --> Status`) you can perform a health check on the system, on
|
|
the bottom of the status overview is a button named **Run an audit** which can be expanded to offer the **Health** selection.
|
|
|
|
When clicked this outputs something like the following:
|
|
|
|
.. code-block:: text
|
|
|
|
***GOT REQUEST TO AUDIT HEALTH***
|
|
>>> Check installed kernel version
|
|
Version 19.7.3 is correct.
|
|
>>> Check for missing or altered kernel files
|
|
No problems detected.
|
|
>>> Check installed base version
|
|
Version 19.7.3 is correct.
|
|
>>> Check for missing or altered base files
|
|
No problems detected.
|
|
>>> Check for and install missing package dependencies
|
|
Checking all packages: .......... done
|
|
>>> Check for missing or altered package files
|
|
Checking all packages: ....
|
|
opnsense-19.7.4_1: checksum mismatch for /usr/local/etc/inc/auth.inc
|
|
Checking all packages...
|
|
Checking all packages......... done
|
|
***DONE***
|
|
|
|
When mismatches are reported, you can reinstall affected packages in the **Packages** section of the firmware screen.
|
|
In the case above you would reinstall opnsense, since the :code:`auth.inc` looks tainted.
|
|
|
|
.. Note::
|
|
|
|
We advise to include the output of the health check if it seems to report issues when creating bug reports on GitHub.
|
|
|
|
|
|
.. Tip::
|
|
|
|
Always try to be precise in issue reports, either if their about a possible bug or a feature request, it helps if
|
|
intentions are absolutely clear. Our GitHub repositories use templates which should guide you through, we kindly
|
|
ask you to use them (tickets not using our templates are treated as low priority).
