Here some rough steps to change the password of the database. The password can only be changed and not recovered.
The database contains a table called v_users which contains the username, password and salt. The password is the md5 hash of the password and the salt.
Use the following commands to generate the password hash. Don't forget to provide your own salt and password.
echo '<?php $salt = "random-salt-goes-here";$password = "put your password here"; echo md5($salt.$password)."\n"; ?>' > /tmp/test.php
Run the php file from command line.
Install sqlite3 which can be be used to modify the database fusionpbx.db. Then open the database with the following:
Connect to the PostgreSQL database. Once you are running psql you can use \l to list the databases and \c to connect to one of them. After running the SQL Query then use \q to quit.
su postgres psql \c fusionpbx
Change the Password
The hashed password and the salt can be updated using the command,
update v_users set password = 'replace-with-password-hash-from-php-script', salt = 'replace-with-your-random-salt' where username = 'superadmin';
