I'm using the PHP library for NETCONF: https://github.com/Juniper/netconf-php . So far I have managed to get the configuration parts I need for my scripts, but the recent challenge remains loading new configurations into the router. The logs on my router:
Nov 27 14:34:48 router.nl sshd[78164]: subsystem request for netconf by user user
Nov 27 14:34:48 router.nl mgd[78168]: UI_CMDLINE_READ_LINE: User 'x', command 'xml-mode netconf need-trailer '
Nov 27 14:34:48 router.nl file[78167]: UI_LOGIN_EVENT: User 'x' login, class 'j-super-user' [78167], ssh-connection 'x.x.x.x 46796 x.x.x.x 22', client-mode 'netconf'
Nov 27 14:34:48 router.nl file[78167]: UI_NETCONF_CMD: User 'x' used NETCONF client to run command 'lock cannot reconstruct arguments'
Nov 27 14:34:48 router.nl file[78167]: UI_NETCONF_CMD: User 'x' used NETCONF client to run command 'edit-config cannot reconstruct arguments default-operation=merge cannot reconstruct arguments'
Nov 27 14:34:48 router.nl file[78167]: UI_NETCONF_CMD: User 'x' used NETCONF client to run command 'unlock cannot reconstruct arguments'
Nov 27 14:34:48 router.nl file[78167]: UI_NETCONF_CMD: User 'x' used NETCONF client to run command 'close-session'
It keeps complaining about not being able to reconstruct arguments. This is the script I'm trying to get working:
require_once '../app/include/netconf/Device.php';
$deviceParams = [
'hostname' => 'x.x.x.x',
'username' => 'x',
'password' => 'password',
'port' => 22
];
$this->device = new Device($deviceParams);
$this->connectRouter();
$islocked = $this->device->lock_config();
$command = '<system><services><ftp/></services></system>';
if($islocked) {
$this->device->load_xml_configuration($command, 'merge');
}
$this->device->unlock_config();
$this->device->close();
I've set up traceoqptions under the netconf { ssh { tree and this is one of the outputs (everything seems ok):
Nov 30 10:41:57 [86546] Incoming:

The first logs I have shown in my OP do not say anything but telling me that something went wrong. The traceoptions however, did tell me important information after I tried locking/unlocking the configuration:
Nov 30 12:06:43 [86767] Outgoing: <rpc-error>

A quick search on 'configuration database modified' implies that there were still some uncommitted changes ( http://www.juniper.net/documentation/en_US/junos13.3/topics/topic-map/junos-script-automation-service-template-automation.html , bottom page ):
Problem
You see the following message when creating, updating, or deleting a service on a device through a NETCONF session:
<output>
configuration database modified
</output>
The configuration has previously uncommitted changes, and the service script cannot commit the service configuration changes.
Simply typing 'commit' in the configuration mode made the error go away. I hope I have helped / will help others in the future.
