# Simple script to turn off roku. Send it an ip address of your roku and it'll turn it off. 

# This script is so green and earth friendly it basically refrigerates the polar ice caps. 
# Schedule this with cron to turn your roku and most likely TV off. 
# 
# crontab -e 
# ex. shut off my roku at 8 am every day if roku is on 192.168.1.2
# 0 8 * * * ./rokuoff.py 192.168.1.2

If you are considering making a network change and don't want to risk a down machine that you would then have to console into... here's what to do. 

1. Copy your working network configuration 
cp /etc/network/interfaces /etc/network/interfaces.working.bak 

2. Make your changes to the network connection
cat /etc/network/interfaces.withchanges > /etc/network/interfaces

3. Create a script to undo the change 
vi /root/reset_net.sh

# run this as root
# This is basically stolen from digital ocean's guide, just made to be a bit more automated.
# This will install and configure fail2ban for a centos7 system using firewalld.
# No iptables were injured in the making of this gist.

# Install fail2ban.
yum -y install epel-release

# This is a template for a script that only runs when it's not already running. The first thing this will do is to check #
# to make sure that it is not running.                                                                                   #
