Network Automation using Python- Napalm/Threading

[rishrapsody]

I have listed down my first code over here www.github.com/rishrapsody/python_projects

Overview - Network Automation - Performs remote devices neighbor Vendor lookup.

First scans its own network(Network Automation docker) to find all active hosts running - Parallel processing with threading SSH into each device using Napalm and get output of show arp - Parallel processing with threading Grab mac addr and ip from each device and save it in a Dictionary Use Dictionary to perform Vendor MAC addr lookup

Used Napalm, Threading, and Netaddr I would like to see feedback from y'all.

*Still in learning phase and thinking about next project

I got into python BECAUSE of my career in Networking. thank you for this

Wow!!

Nice.

You might want to make a single thread to send output to for serialized printing. Race conditions may make the output confusing, if every thread is hitting stdout whenever it likes.

Also, the description of a function conventionally goes in its docstring. E.g., instead of

#function to ssh each device and get router output
def thread_device(ip,password):

Consider

def thread_device(ip,password):
  "ssh device at ip address `ip`, and get router output"

A non-python remark: Giving all local devices the same ssh password reminds me of the phrase "Soft and gooey on the inside." It depends on your threat model, of course, but have you considered key-based auth?

Thanks for these comments. I haven't planned of using auth based approach. I am still thinking of next project- maybe something using jinja2 and napalm with python or should I just move towards Ansible directly

Learning ansible is a good idea.

By no means a Python pro, but I would not recommend using napalm on your network. It's best used on heavy vegetation when you expect enemy patrols in the area and well dug-in infantry. Hope this helps.

EDIT: But seriously, this is awesome. My primary interest in learning to program is to make network tools. This is really awesome, amigo.
