LAB automation

kasuj

Hi,

I'm looking for an script to automatically download/upload configuration files to a network devices mainly cisco or juniper. I'm trying to make my lab more automatic. Do you use/have anything like that?

Thank you,

So are you wanting a script that logs into the device, pulls a new config down to start up and reloads the box? If so you can find plenty of perl and python scripts out there that will run commands on a Cisco router. Just set it up with the parameters you want and let it fly.

Yes thats exactly what I need. Can you give me any examples?

I was thinking about creating something with expect but maybe there is something that works and I don't have to reinvent the wheel.

Here is one in perl written by a guy I used to work with.

Great Perl Script

Pretty straight forward. It takes a flat text file with routers and file with commands and executes them. You could probably fix it up to take a variable of the router hostname to match a config file so each router can pull a different config.

A google search will pull up many more on the internet in all sorts of languages. I've always just grabbed something and modified it to meet my needs rather than writing something from scratch since I'm not all that great at scripting.

Some old python script I wrote. https://github.com/lovwal/sysadmin/blob/master/sshscripts/template
Edit the command variables and add some sleep while fetching the new images. Use with caution though seeing its multithreaded and not 100% reliable all the time depending on what you are doing.
