Shell scripts and config files from my article on creating a Bitcoin Core node on Raspberry Pi 3

• Adapt paths from .bashrc to reflect your local config

• Adapt aliases from .bash_aliases

To create a proper firewall use iptables.sh script and put it somewhere under /usr/local, for example /usr/local/bin. Don't forget to make it executable with chmod +x iptables.sh

• Install iptables-persistent with apt-get install iptables-persistent

• Create a config dir for future iptables fiter rules: sudo mkdir /etc/iptables

• Execute the firewall script: sudo /usr/local/bin/iptables.sh and press ENTER when done.

• Check if the firewall rules have been instantiated correctly: sudo iptables -L

• Install multitail package with sudo apt-get install multitail

• Read the manual or just put the provided .multitailrc into your home dir
