Run the following command to generate a new database:
$ sudo aideinit
By default, the database will be written to the file
/var/lib/aide/aide.db.new.
Storing the database, the configuration file /etc/aide.conf, and the binary
/usr/bin/aide.wrapper
(or hashes of these files), in a secure location (such as on read-only media) provides additional assurance about their integrity.
The newly-generated database can be installed as follows:
$ sudo cp /var/lib/aide/aide.db.new /var/lib/aide/aide.db
To initiate a manual check, run the following command:
$ sudo /usr/bin/aide.wrapper --check
If this check produces any unexpected output, investigate.
