Ansible (2.5.0) Module Failure - ios_user, ios_ping

Question

I was in the middle of programming an Ansible playbook and suddenly I started getting a "Module Error" and I have no idea why. I tried each module individually in the CLI with every option. I ran a syntax check (--syntax-check) and there were no problems with that. I think this mught be a bug.

"ios_facts" module works:

$ ansible all -m ios_facts -i Resources/Inventory/hosts 

10.20.30.111 | SUCCESS => {

"ansible_facts": {
    "ansible_net_all_ipv4_addresses": [
        "10.20.30.111"
    ], 
    "ansible_net_all_ipv6_addresses": [], 
    "ansible_net_filesystems": [
        "flash:"
(...)

"ios_ping" returns this error:

$ ansible all -m ios_ping -a"dest='1.1.1.1'" -i Resources/Inventory/hosts

10.20.30.111 | FAILED! => { "changed": false, "module_stderr": "Traceback (most recent call last):\n File \"/tmp/ansible_WOH7nd/ansible_module_ios_ping.py\", line 215, in \n main()\n File \"/tmp/ansible_WOH7nd/ansible_module_ios_ping.py\", line 151, in main\n success, rx, tx, rtt = parse_ping(stats)\n File \"/tmp/ansible_WOH7nd/ansible_module_ios_ping.py\", line 200, in parse_ping\n return rate.group(\"pct\"), rate.group(\"rx\"), rate.group(\"tx\"), rtt.groupdict()\nAttributeError: 'NoneType' object has no attribute 'group'\n", "module_stdout": "", "msg": "MODULE FAILURE", "rc": 1}

"ios_user" returns this error:

IOS config: config.text

Ansible Inventory: Resources/Inventory/hosts

Ansible Version: 2.5.0

Cisco IOS version: 12.2(55)SE

The connection works fine and I also was able to execute the "ios_system" module. Do you guys have any idea what this might be?

Answer 1

As it turns out, the ios_user module is not compatible with Cisco IOS version 12.2(55)SE because it is using an output filter ("section") which is not available for this device's version. To fix this, I just had to substitute the word "section" with "include" in the ansible/modules/network/ios/ios_user.py file (the complete file path depends on your ansible instalation, because you might be using a virtual environment). Here is the module code. So that part of the the code then looked like this:

def map_config_to_obj(module):
    data = get_config(module, flags=['| include username'])

   match = re.findall(r'^username (\S+)', data, re.M)
    if not match:
        return list()

The module now works as intendeed. As for the ios_ping, I've been trying to reverse engineer it's code and, in my opinion, has more then one bug. I think it is working only when the success rate is above 0%.
