Hey there,

i'm trying to control the kea server by using the control agent.

I already implemented a web-frontend to the database (mysql) to show all the leases and reservations.
Now I'm trying to get the running configuration by requesting the control agent.

$msg = array("command" => "config-get", "service" => "[ dhcp4 ]");
$message = json_encode($msg);

//$message = '{ "command": "config-get", "service": "dhcp4" }';
$len = strlen($message);

echo print_r($message, true), "\n";

$ch = curl_init('http://127.0.0.1:8080/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $message);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
     'Content-type: application/json',
     'Content-Length: '. $len)
);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);

$ret = curl_exec($ch);
if($ret === false)
{
    echo 'Curl error: ' . curl_error($ch);
}
else
{
     echo print_r($ret, true);
    echo 'Operation completed without any errors';
}

All I receive is the following:
{"command":"config-get","service":"[ dhcp4 ]"}
{ "result": 400, "text": "Bad Request" }
Operation completed without any errors

I tried a lot of things:

-       dhcp4 with or without brackets

-       using the documented string (http://kea.isc.org/docs/kea-guide.html#ctrl-channel-client)

-       with and without timeouts

-       different HTTPHEADER (with, and without Content-Length like in the documentation)

The service is up and running, if i'm using the shell and curl the example works.
I also tried to get a clue by reading the log (DEBUG, Level 99) but there is just a lousy message "HTTP_DATA_RECEIVED received 152 bytes from 127.0.0.1" and "DEBUG [kea-ctrl-agent.http] HTTP_RESPONSE_SEND sending HTTP response HTTP/1.1 400 Bad Request#015#012 to 127.0.0.1"

Does anybody have a clue how to successfully connect and receive a proper message?

Thanks in advance

Sebastian

I am hoping that the only thing that you have to correct is to do this:

"service" => [ "dhcp4" ]

rather than

"service" => "[ dhcp4 ]"

Hi Guys,

After some testing time I installed Kea 1.2 and it runs on Debian 8. We
ordered the forensic hook and I got a Zip File -> but I dont have any Idea
how to install it. Also not found a documentation about this.

And my second Question: Is There also a guide how to upgrade from 1.2 to 1.3
without losing lease informations from Database? Also not found anything.

Sorry Im really newbie with KEA and needs someone who have little bit more
experience.

Freundliche Gr?sse
