Cant SSH / PING to Network Devices

Archives Ansible Project

I am a Newbie to Ansible , writing my first playbook.

I can not SSH / PING to network Devices.

`
leaf-1 | UNREACHABLE! => {
“changed”: false,
“msg”: “Authentication failure.”,
“unreachable”: true
}
leaf-2 | UNREACHABLE! => {
“changed”: false,
“msg”: “Authentication failure.”,
“unreachable”: true
}

i can PING / SSH to network devices from Ansible server but when i run the playbook , it fails.

No idea if i have to add something in playbook or ansible.cfg . Any Suggestion please ?

show how you you ssh in with ansible and without ansible. Your plsybook and cfg file.

`
ansible.cfg :

[defaults]
inventory = ./inventories/

`

`
Inventories :

[leaf]

leaf-1
leaf-2

`

playbook :

- hosts: all
  remote_user: admin
  vars:
    authorized_key_list:
      - name: admin
        authorized_keys:
         - key: "{{ lookup('file', '~/.ssh/id_rsa.pub') }}"
           state: present
  roles:
    - { role: GROG.authorized-key }

First make sure ansible can actually sign in to the target hosts before trying to use roles. I’m guessing here but that role name indicates something related which might impact the connection.

So best to start here:

https://docs.ansible.com/ansible/latest/user_guide/intro_getting_started.html#connecting-to-remote-nodes

And then try something simple such as the a file or copy task.
Once that works move on to more complicated things like roles.

Use the ansible_user variable.
