Configuration
|

-------------
|

|
||||
To configure 0x0, copy ``instance/config.example.py`` to ``instance/config.py``, then edit
|
||||
it. Resonable defaults are set, but there's a couple options you'll need to change
|
||||
before running 0x0 for the first time.
|
||||
To configure 0x0, create ``instance/config.py``.
|
||||
The defaults are at the start of ``fhost.py``. To change them,
|
||||
add them to ``instance/config.py``— for example::
|
||||
|
||||
By default, the configuration is stored in the Flask instance directory.
|
||||
Normally, this is in `./instance`, but it might be different for your system.
|
||||
For details, see
|
||||
SQLALCHEMY_DATABASE_URI = "sqlite:///some/path/db.sqlite"
|
||||
|
||||
For more information on instance configuration, see
|
||||
`the Flask documentation <https://flask.palletsprojects.com/en/2.0.x/config/#instance-folders>`_.

problem for example when streaming media files: It won’t be possible to seek,

To make files expire, simply run ``FLASK_APP=fhost flask prune`` every

Virus Scanning
|
||||
--------------
|
||||
|
||||
0x0 can scan its files with ClamAV’s daemon. As this can take a long time
|
||||
for larger files, this does not happen immediately but instead every time
|
||||
you run the ``vscan`` command. It is recommended to configure a systemd
|
||||
timer or cronjob to do this periodically. Examples are included::
|
||||
|
||||
0x0-vscan.service
|
||||
0x0-vscan.timer
|
||||
|
||||
Remember to adjust your size limits in clamd.conf, including
|

``StreamMaxLength``!

This feature requires the `clamd module <https://pypi.org/project/clamd/>`_.
