Re: [asterisk-users] Using PHP to reload extensions
Ciao Tzafrir,
The only real benefit is if you can limit the permissions you give to
that specific manager user. But there's a limit to ohw useful this can
be. Even write=command alone allows changing the dialplan ('dialplan
add' / 'dialplan remove') and running an arbitrary command as the
asterisk user (originate a call to the application System).
Maybe it could be good to limit in manager.conf which commands can be executed
by each user.
In this way, we could give more granular permissions, at the price of a
slightly more complex manager.conf syntax.
HND,

Not that, in essense, this permits the web server's user to control
Asterisk as well - the web server's user must be able to read the
password from somewhere.

No, because then asterisk would be presented three arguments: '-rx',
'extensions', and 'reload' -- as 'extensions' is not a command by
itself, and the 'reload' appears superfluous to asterisk, this would not
work as desired.
Asterisk needs to be presented two arguments - the first is '-rx', the
second is extensions reload (needs additional quoting to contain the
space) which is actually a parameter to the '-x' switch just used.
$output = shell_exec(asterisk -rx 'extensions reload')
is right.

that with double quotes, PHP is allowed to make $variable substitution

Re: [asterisk-users] Using PHP to reload extensions
Hello,
I am trying to use PHP to reload the extensions in an Asterisk
installation. I keep getting this error:
Easiest way without compromising security or changing permissions. Use
the AMI.
1. Download phpagi (Just google it)
2. Use it to connect to the Manager interface
3. Use it to issue:
Action: Command
Command: reload
Here's the two functions I've been using. Add a new user to
manager.conf with the appropriate permissions and this should work
fine.
Hope that helps,
-Michael
function extensions_reload() {
return asterisk_exec(dialplan reload);
}
function asterisk_exec($cmd, $output=NULL) {
$token = md5(uniqid(rand()));
$errno = 0;
$errstr = 0;
$fp = fsockopen(localhost, 5038, $errno, $errstr, 20);
if (!$fp) {
return 1;
}
fputs($fp, Action: login\r\n);
fputs($fp, Username: newusername\r\n);
fputs($fp, Secret: newpassword\r\n);
fputs($fp, Events: off\r\n\r\n);
usleep(500);
fputs($fp, Action: COMMAND\r\n);
fputs($fp, command: $cmd\r\n);
fputs($fp, ActionID: $token\r\n\r\n);
usleep(500);
$out = fread($fp, 38000);
while(strpos($out,--END COMMAND--)==0) {
$out .= fread($fp, 38000);
}
fclose ($fp);
$out = substr($out, strpos($out, ActionID));
$out = substr($out, strpos($out, \n) + 1);
$out = substr($out, 0, strpos($out, --END COMMAND--) - 1);
$output = $out;
return 0;

I guess your web server does not run as root and thus is not
allowed to invoke asterisk. (Try
echo shell_exec('id');
or
echo get_current_user();
in PHP.)
A possible solution (although not nice): Add
www-data ALL=(ALL) NOPASSWD: ALL
to /etc/sudoers (depending on your distribution etc. the Apache user
might be www-data / apache / ...) and in the PHP script run
shell_exec('sudo asterisk -rx extensions reload');

If running a script from a browser, it is usually run as nobody, from
the command line it is whatever user you are, probably root.

Easiest way without compromising security or changing permissions. Use
the AMI.
1. Download phpagi (Just google it)
2. Use it to connect to the Manager interface
3. Use it to issue:
Action: Command
Command: reload
phpagi actually has a method in the manager class to do this. Just use
the Command function with a parameter of reload
