Not able to push playbook to Juniper Switch

[G24joshi (Ganesh)]

I am unable to push playbook tasks to our Juniper switch. If I just create a simple playbook for gathering the facts, I am getting below error “[Errno -2] Name or service not known”. and this error is same for every module.
Connectivity is fine as I am able to ssh the Juniper switch from the Ansible server.
I am pasting the playbook below as well as the error with -vvvv.

Please find my Playbook.

Playbook:
- hosts: juniperswitch
  gather_facts: no
  vars:
     ansible_command_timeout: 1800

  tasks:
    - name: get the facts
      junipernetworks.junos.junos_facts:
      register: value1

    - name: Print in screen
      debug:
        var: value1

---

error after adding -vvvv.

The full traceback is:

Hey @G24joshi can you provide an inventory so I can see how you setup your ansible_network_os?

Hi @IPvSean

Thanks, Please find below hosts file and group_vars file for my juniper switch.

[root@lonans01 juniperymls]# cat /etc/ansible/hosts
[juniperswitch]
57.3.62.21
-----------------
[root@lonans01 juniperymls]# cat /etc/ansible/group_vars/juniperswitch
ansible_network_os: junos
ansible_user: admin.b1
ansible_password: Pass@#$$
ansible_connection: netconf
ansible_become: yes
ansible_become_method: enable
ansible_become_password: Pass@#$$
[root@lonans01 juniperymls]#

Two question/requests:

1. Is netconf enabled on the Juniper device? You can use the junos_netconf module to enable it: junipernetworks.junos.junos_netconf module – Configures the Junos Netconf system service — Ansible Documentation

You can see how I use it here: https://github.com/ansible/workshops/blob/4c1bce058c55c435766a99dc5528b4fa1e1b1d3f/roles/configure_routers/tasks/juniper_default.yml#L19

2. Can you re-run your playbook with -vvvv (4 vs) so I can see what it is doing for the connection?

After enabling netconf in Juniper Device it now working. Thanks a lot. I run below command in juniper device to enable Netconf

set system services netconf ssh port 830
