用PHP NETCONF配置Juniper路由器

Question

我正在为NETCONF：https://github.com/Juniper/netconf-php使用PHP库。到目前为止，我已经成功地获得了脚本所需的配置部件，但最近的挑战仍然是将新配置加载到路由器中。我路由器上的日志：

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'

它一直抱怨不能重建论点。这就是我想要得到的剧本：

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();

我已经在netconf { ssh {树下设置了跟踪，这是输出之一(一切似乎都正常)：

Nov 30 10:41:57 [86546] Incoming:
<rpc><edit-config><target><candidate/></target><default-operation>merge</default-operation><config><configuration><system><services><ftp></ftp></services></system></configuration></config></edit-config></rpc>]]>]]>

我在操作中显示的第一批日志没有说什么，而是告诉我出了问题。然而，在我尝试锁定/解锁配置之后，跟踪选项告诉了我一些重要的信息：

Nov 30 12:06:43 [86767] Outgoing: <rpc-error>
Nov 30 12:06:43 [86767] Outgoing: <error-type>protocol</error-type>
Nov 30 12:06:43 [86767] Outgoing: <error-tag>operation-failed</error-tag>
Nov 30 12:06:43 [86767] Outgoing: <error-severity>error</error-severity>
Nov 30 12:06:43 [86767] Outgoing: <error-message>
Nov 30 12:06:43 [86767] Outgoing: configuration database modified
Nov 30 12:06:43 [86767] Outgoing: </error-message>
Nov 30 12:06:43 [86767] Outgoing: </rpc-error>
Nov 30 12:06:43 [86767] Outgoing: </rpc-reply>
Nov 30 12:06:43 [86767] Outgoing: ]]>]]>

快速搜索“修改配置数据库”意味着仍有一些未提交的更改( US/junos13.3/topics/topic-map/junos-script-automation-service-template-automation.html，底部页)：

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.

只要在配置模式中输入'commit‘，错误就会消失。我希望我将来能帮助别人。

不确定PHP中的netconf (仍在使用)，但在Python中，最好始终使用“配置私有”：

junos_dev.open()
with Config(junos_dev, mode='private') as cu:
  cu.load(some_string, format='set')
  #print cu.diff()
  cu.commit()
junos_dev.close()

(现在我也在这里找到了相关的函数)： /** *这个方法应该被调用，以便在‘私有’模式下进行加载操作。*@param模式*打开配置的模式。*允许模式：“私有”*/公共功能open_configuration($mode)
