How to add new user to Kamailio using PHP shell_exec?

Question

There is a requirement to add a new user to Kamailio programmatically using PHP. I tried to add username and password to subscriber table manually using SQL queries, but it won't works because ha1 and ha1b should be added to the table. I don't know how Kamailio generate ha1 and ha1b. Following are the manually added entries using kamctl tool.

mysql> select * from subscriber limit 2;
+----+----------+---------------+--------------+---------------+----------------------------------+----------------------------------+------+
| id | username | domain        | password     | email_address | ha1                              | ha1b                             | rpid |
+----+----------+---------------+--------------+---------------+----------------------------------+----------------------------------+------+
|  9 | 1010101  | 10.101.101.10 | aswwwwwwwsdf |               | a37d1785953310c206481ca1a33f16b6 | 7e981130f05a547a738d3c29031e89d0 | NULL |
| 10 | 1010102  | 10.101.101.10 | 6eeeeee8a72  |               | 6b574f9047206481ca1a33501d7dbdce | cd9a8b89d926f3cb1290311a8cb8a2a8 | NULL |
+----+----------+---------------+--------------+---------------+----------------------------------+----------------------------------+------+

Then I tried with shell_exec function in PHP to use kamctl command(kamctl add username password). but it will prompt for Kamailio read-write user's password. So following command cannot add new users to Kamailio

$res = shell_exec("sudo kamctl add new_username new_password);   

so, please suggest a way to add new user's to Kamailio programatically.

Answer 1

The problem was about how to provide the password for the prompt coming after the add command.
Here is the solution, you can use echo to pass the password to the prompt and you can use a pipe right before your actual command. So that the prompt will get the echoed password and it will add a new user.

$res = shell_exec("echo password |kamctl add new_username new_password");
