In my home lab I have 4 Juniper in a virtual chassis. I currently use fedora 24 as my host system so I had to install some binaries and fix some code before I got this running. First you have to install the latest stable ansible version.
Then you need junos-eznc. For fedora run the following command
[dobby@dobby ansible]$ sudo pip install junos-eznc
Once I’ve installed the so called pre req I run the following ansible playbook.
- hosts: juniper
gather_facts: no
connection: local
vars:
cli:
host: "{{ inventory_hostname }} "
username: juniper
password: password
port: 22
transport: netconf
tasks:
- name: run show version
junos_command:
commands: show version
provider: "{{ cli }}"
After ansible run I got the following error message:
[dobby@dobby ansible]$ ansible-playbook -i inventory/ junos.yaml -vv
Using /etc/ansible/ansible.cfg as config file
PLAYBOOK: junos.yaml ***********************************************************

fatal: [juniper]: FAILED! => {"changed": false, "failed": true, "msg": "jxmlease is required but does not appear to be installed. It can be installed using `pip install jxmlease`"}
to retry, use: --limit @/home/dobby/Development/ansible/junos.retry

juniper : ok=0 changed=0 unreachable=0 failed=1
Next step was to install jxmlease
[dobby@dobby ansible]$ sudo pip install jxmlease Collecting jxmlease Using cached jxmlease-1.0.1-py2.py3-none-any.whl Installing collected packages: jxmlease Successfully installed jxmlease-1.0.1 You are using pip version 8.0.2, however version 9.0.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command.
After that I run the playbook again and ran into another hurdle.
[dobby@dobby ansible]$ ansible-playbook -i inventory/ junos.yaml -vv

A quick google search for “msg: CTR mode needs counter parameter, not IV)” revealed that the file /usr/lib/python2.7/site-packages/paramiko/transport.py needs patching as the value of IV should be an empty string for this to work. So on line 1649 patch the following:
return self._cipher_info[name]['class'].new(key, self._cipher_info[name]['mode'], iv, counter) to return self._cipher_info[name]['class'].new(key, self._cipher_info[name]['mode'], '', counter)
After that I was successful in running the playbook.
