Hi everybody,

I'm working on getting my hands on ansible to use it for network automation 
purposes. I've a problem with a first simple script which is issuing a show 
command on a switch.

I've to hosts defined in my hosts file /etc/ansible/hosts:

*[...]*
*[nxos]*
*10.20.5.26*
*10.20.5.27*
*[...]*

Now I have this simple playbook:

*---*
*- name: Execute show version on NX-OS Devices*
*  hosts: nxos*
*  gather_facts: no*
*  tasks:*
*  - raw: "show version"*

When I test my playbook I'm getting the following error:

*ansible-playbook playbooks/show_version.yml -vvv*

*PLAY [Execute show version on NX-OS Devices] 
***********************************

*TASK: [raw show version] 
*******************************************************
*<10.20.5.26> EXEC show version*
*failed: [10.20.5.26] => {"rc": 127}*
*stderr: /bin/sh: 1: show: not found*

*<10.20.5.27> EXEC show version*
*failed: [10.20.5.27] => {"rc": 127}*
*stderr: /bin/sh: 1: show: not found*


*FATAL: all hosts have already failed -- aborting*

*PLAY RECAP 
*********************************************************************
*           to retry, use: --limit @/root/show_version.retry*

*10.20.5.26                 : ok=0    changed=0    unreachable=0   
 failed=1*
*10.20.5.27                 : ok=0    changed=0    unreachable=0   
 failed=1*

This playbook was working perfect on Debian 9 and Ansible 2.2 or 2.3. Now 
I'm testing this on Ansible 1.7.2, Debian 7 and Python 2.7.3.

It's looking like Ansible isn't able to connect to the networking devices 
because it doesn't try to connect via SSH. Iwas looking through the 
internet for some help but only found things like change your /bin/bash in 
ansible.cfg file but this won't help me as I need to find out why Ansible 
isn't able to get to the networking devices.

Thanks in advance.

Tobias
