Bash script that pushes all Pi-hole blacklist and whitelist settings to a secondary server for redundancy
Script assumes 2 servers exist: SERVER1 (containing current configuration) & SERVER2 (secondary server) which have ability to communicate directly over the network. Default port for SSH on SERVER2 is also assumed.
Passwordless SSH login is required between SERVER1 & SERVER2 for the script to work:
- From SERVER1 run: ssh-keygen -t rsa
- From SERVER1 run: ssh-copy-id user@SERVER2
- To test from SERVER1 run: ssh user@SERVER2
Ideally script should be scheduled as cron job to perform syncronization at regular intervals
Script must be executed as sudo on SERVER1
sudo ./pi-hole-push-config.sh
