Running root commands from custom FreePBX module

SamShomi · August 27, 2024, 5:16pm

I am creating a custom FreePBX module. This is my first time trying to develop something for FreePBX so I am trying to learn how to use the built-in libraries.

My module will need to run Linux commands as root. I can’t seem to find anything in the BMO library to do that. I believe the sysadmin module runs some commands as root so there must be some way to do it from a FreePBX module.

To do it the “built in way” You have to use hooks through sysadmin. The module has to be signed.

See:

github.com

FreePBX/firewall/blob/release/16.0/Firewall.class.php#L601


      
          				_("No Trusted Network or Host has been defined. Every server should have a 'Trusted' host or network to ensure that in case of configuration error, the machine is still accessible."),
          				"?display=firewall&page=about&tab=networks",
          				true, // Reset on update.
          				true); // Can delete
          		}
          
          		return array($status, $trusted);
          	}
          
          	// Run a sysadmin-managed root hook.
          	public function runHook($hookname,$params = false) {
          		// Runs a new style Syadmin hook
          		if (!file_exists("/etc/incron.d/sysadmin")) {
          			throw new \Exception("Sysadmin RPM not up to date, or not a known OS. Can not start System Firewall. See http://bit.ly/fpbxfirewall");
          		}
          
          		$basedir = $this->get_astspooldir()."/incron";
          		if (!is_dir($basedir)) {
          			throw new \Exception("$basedir is not a directory");
          		}

Just what I am looking for. Thanks.

I was hoping I wouldn’t have to sign it during development. I know that when I tried to modify the firewall module it wouldn’t work even if I disabled signature checking.

That’s the downside of commercial modules , you will never know what they are doing
