Automation

Guys, I need help, I'm a layman.

I have an installed network of the SRX300, but I already had many problems with the lack of energy.
To help you install a no-break even then a 20-minute battery life.
I would like to know how to make a script to turn off the juniper.
On windows I created a GPO to execute a command when I shut down the computer,
I do not know how to create the script to turn off Juniper equipment.

You can use Python to power off a Junos device from a Windows PC.

1. Install Python (Refer to PYEZ cookbook, link at the bootom)

2. Install Junos PYEZ library on Windows PC. (Refer to PYEZ cookbook, link at the bootom)

3. Open PowerShell and run the following commands, you can use the same in a Python script as well

4. Ensure netconf over ssh is enabled on SRX device

> show configuration system services netconf
ssh;

Windows PowerShell

First of all I would like to thank you for answering me. I ran exactly the step-by-step and ran and hung up my Juniper. My question is that I saved the Script as PS1 (powershell) and it's error. I do not know if this is the correct procedure. I just could not automate the script.

You can save the file as shutdown.py, complete file contents at the bottom.

Open Powershell and change to the directory with the file in it, and execute the script

python.exe .\shutdown.py

--> Shutdown.py

import jnpr.junos
from jnpr.junos import Device
from jnpr.junos.exception import ConnectError
srx=Device(host='<IP address of host>',user='root',password='password')
from jnpr.junos.utils.sw import SW
srx.open()
sw=SW(srx)
print(sw.poweroff())

Thank You,

==========

Please mark the Solution as Accepted, Kudos are appreciated as well.
