About this Hands-on Lab

Cat Corp. is trialing a setup of Ansible in their environment. They’ve set up an Ansible host server and need to set up a couple of backup servers. You’ve been contracted to write a playbook that will install `csh` on the servers. Additionally, for this backup software, each server can run a different number of backup streams. This is configurable in a file located at `/opt/backup/streams`. You also need to populate this file with the value stored in the host-based variable managed in the Ansible inventory.

>**Note:** Make sure to elevate to `root` once logged in. The reason for this is because of how the lab server’s version of Ansible is installed.
