Hope this helps in resolving your problem

Check where kannel saves log file under the SMSBOX group

<conf file>
group = smsbox
log-level = 0
...
log-file = "/var/log/kannel/smsbox.log"
...

See if the dlr is set, in this example it is sent via XML

You can also see in the log file if the SMSC did return a value back,
this snipped of the log file the SMSC returned a failed reponse

Should you get these values you are one step closer, you are sending and
receiving the DLR's
= 2 =
Now, you know your DLR are working, next step where it terminates:
- Webserver -
Make sure the webserver understands your request, this example here the
web server uses 'rewrite rules', so this server does not understand the
?key=value& schema
Rewite Example:
http://domain.tld/dlr/status/id/26/status/%d/response/%A/smsc/%i/from/%Q/to/%q/
'Basic' Example of rewrite rule equivalent:
http://domain.tld/dlr/status.php?id=26&status=%d&response=%A&smsc=%i&from=%Q&to=%q
The chance that a webserver has a rewrite rule is very slim but still a
possibility
- Syntax -
Make sure the forming of the URL is correct or you will get errors
http//domain.tld/dlr/status.php?id=123
The above url will NEVER work... there is no ':', something small like
that can be the cause of huge headaches
= 3 =
examples used:
dlr url: http://domain.tld/dlr/status.php?id=123&mask=16
php file: status.php
log file: log.txt
- PHP -
simple php file that should help
<?php
// status.php - to receive and log - php5
// sets php to display errors
ini_set('display_errors', 'On');
ini_set('error_reporting ', E_ALL);
// set webserver to return plain text
header('Content-Type: text/plain');
// variables from the $_GET
// just a variable
$id = $_GET['id'];
// the dlr mask status
$status = $_GET['mask'];
// the log file
$logfile = '/path/to/log.txt';
// see if you can write to the log file
if (!is_writable($logfile)){
echo 'The log file permissions are not correct, cannot write to it,
with root access you can try: chown www:www ' . $logfile . ' or chmod
a+w ' . $logfile;
exit();
}
// see if values are not empty
if (!empty($id) && !empty($status)){
echo "either id or status does not have a value";
exit();
}
// creates log line with date, values and adds line break at end
$logfileLine = '[' . date('Y-m-d H:i:s') . '] ID = ' . $id . ' Status =
' . $status . "\n";
// writes log line to log file and appends to log file every time
if (!file_put_conents($logfile, $logfileLine, FILE_APPEND)){
echo 'if you get this error message something very wierd is going on';
exit();
}
echo 'all done :)';
?>
ps: I have not tested the php script show it might be buggy
- Basic Test -
now, open your web browser and enter the url as you would like to
receive the dlr
http://domain.tld/dlr/status.php?id=123&mask=16
The return values you get from the browser will give you a good
indication of the possible error (if any) on the php side
