junos-multi-command

junos-multi-command enables you to run a console command simultaneously on many network devices running the Juniper Junos operating system. The ability to group network devices in the config.yaml file gives the operator the ability to pick and choose the type of device or logical grouping for the selected command.

What is really nifty is that it is involked at the command prompt giving the operator the ability to execute commands on many routers in seconds from a terminal window.

Functions

• Run a single command on a few or even hundreds of network devices with results returned.
• Uses a config.yaml file to define your hosts in zones allowing you to group like network devices.
• Very rapid execution of commands on multiple routers.
• Secure transfer of commands and results via Netconf (SSH)

Installation

Download from github and install dependencies, or type "easy_install junos-multi-command" and have the dependencies and python script installed automatically.

Platform

Should work on any platform, UNIX, Windows, etc

Dependencies

• ncclient - Netconf interface to Juniper devices.
• PyYaml - YAML parsers for python.
• getpass - used to obsecure password prompt.

Configuration

Ensure you have a proper config.yaml file in your current directory as the script looks for it realitive to your current directory.

Configuration file is in YAML format and is divided into zones, below is an example.

Sample config.yaml [root@localhost junos-multi-command]# more config.yaml firewalls:

• 172.16.50.200
• 172.16.50.201

routers:

• 172.16.50.200

Usage

[root@localhost junos-multi-command]# ./junos-multi-command.py -h
usage: junos-multi-command.py [-h] -z ZONE -c COMMAND [-o OUTPUT]

Run a command on many Juniper Junos OS devices via Netconf.

optional arguments:
  -h, --help            show this help message and exit
  -z ZONE, --zone ZONE  category of network devices to run command against.
  -c COMMAND, --command COMMAND
                        command in quotes.
  -o OUTPUT, --output OUTPUT
                        file to output results.

i.e. junos-multi-command.py --zone firewalls --command "show chassis hardware"
