Alpine Linux on Raspberry Pi Basics: Security

In this video we will be reviewing the Linux command line on Alpine Linux running on a Raspberry Pi. We will be reviewing security practices and methodology to keep your system and data safe. After watching this, you will be well on your way to being a power user!

Update: There was an omission in the defined iptables rules that prevented internet access from the local machine because existing connections were blocked inbound and outbound. Use the following commands to add the needed rules.

# Commands #
iptables -A INPUT -m conntrack –ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A OUTPUT -m conntrack –ctstate ESTABLISHED -j ACCEPT
/etc/init.d/iptables save
lbu commit -d
# End Commands #

  • I added some notes in the description about an omission in the iptables configuration that prevented internet access since existing connections were not permitted. The commands in the description add those rules and save them.
