CODE MISSION

With this code I want to help all the engineers who have to backup configurations, store or retrieve data from multiple devices into a single or multiple devices-named files. Thanks to this code you'll be able to push a defined list of commands to a static or dynamic list of IP addresses.

There are two versions:

  • Static: The code will use the list of the IP Addresses defined inside the file called "IPAddressList.txt". Please put one IP per line.
  • Dynamic: The code will ask you which network you want to scan and he creates a list with all the reachable devices (via ICMP) in the provided network.

Each version has two different ways to store the data:

  • Create: The code will create one file for each device
  • Append: The code will create a single file with all the outputs

It's up to you!

Static code list of operations:

  • Open the file called "IPAddressList.txt" and store it in a list
  • Open the file called "Commands.txt" and store it in a list
  • Verify if the devices in the IPAddressList are reachable via ICMP
  • SSH connection to each IP
  • Push commands (stored in the Commands list)
  • Store outputs in dedicated files (create version) o unique file (append version)

Dynamic code list of operations:

  • Scan a network provided by the user (via ICMP, it's automatic)
  • Store the reachable IP in a list
  • SSH connection to each IP. If it's not a Cisco device skip it.
  • Push commands (stored in the Commands list)
  • Store outputs in dedicated files (create version) o unique file (append version)

MODULES

Install the following modules:

pip3 install netmiko
pip3 install ping3
pip3 install networkscan

USERNAME/PASSWORD

The code does not have any pre-defined username/password. When you run the code it will ask you the username and password for the devices.

CISCO VERSION

Tested and working with:

  • IOS XE
  • NX-OS
  • IOS

RUN THE CODE

Create a virtual environment in order to test the code:

python3 -m venv TEST
source TEST/bin/activate
cd TEST/
git clone https://github.com/thetechguy-it/show_commands.git
cd show_commands/
pip3 install netmiko
pip3 install ping3
pip3 install networkscan
sudo python3 < scriptname >.py

The code will create a folder called "BACKUP" and then another folder with the date. Inside this second folder, you will find all your files.
