Марионетка и MCollective

А puppet.dll был добавлен в /usr/libexec/mcollective/mcollective/agent и распознается MCollective после перезапуска служб.

[vagrant@localhost ~]$ mco plugin doc
Please specify a plugin. Available plugins are:

Agents:
  puppet                    Run Puppet agent, get its status, and enable/disable it
  rpcutil                   General helpful actions that expose stats and internals to SimpleRPC clients

Проблема

Хотя хост распознается, запустить Puppet на хосте с помощью MCollective невозможно.

[vagrant@localhost ~]$ mco rpc puppet runonce
Discovering hosts using the mc method for 2 second(s) .... 0

No request sent, we did not discover any nodes.



[vagrant@localhost ~]$ mco ping
localhost.localdomain                    time=106.18 ms

Обновить

Проблема сохраняется, если Puppet Agent запущен.

[root@localhost vagrant]# mco ping
localhost.localdomain                    time=257.15 ms

Попытка решить проблему, прочитав это руководство в данный момент.

Кажется, что плагин Puppet не распознается клиентом.
