JSON Server returns "invalid method" for all function calls with Services 6.x-2.x-dev

Yes, I saw that there was a new key auth module to activate, but I activated that with no improvement.
Other things I did: uninstalled services competely, deleted module/services entries in system table, cleared out caches,
then I made a completely virgin drupal install, with json_server and services 2dev:
no authentication, anon given load node data perms, made a page node, tried node.view in the services browser, it returned the node.
then here is my test remote service call:
ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_URL, 'http://mysite.com/drupaltest/services/json');

$data = array(
'method' => 'node.view',
'nid' => 1,
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
return $result;

I get back: { "#error": true, "#data": "Invalid method node.view" }

Now the fact is that this php is running on the same server, but a different domain as the drupal service; don't know if that might be a factor.

Thanks

Correct, in my drupal virgin install node service is activated, shows node.get, node.view, node.save, node.delete in the services broswer, where pasting {"type":"page","title":"test"} in the node field for node.save creates a new node, but I can't get any love from my remote methods.

Is necessary to call system.connect before trying to access any of the other methods?

using php cURL to try system.connect via json_server I get { "#error": true, "#data": "Invalid method system.connect" }
however using amfphp from flash I succeed with system.connect, and indeed I seem to be able to use all the services. This doesn't help my original vote.setVote problem though; I still need to use serverside php there. Maybe the problem is the json_server?
