Retrieve or update host files across multiple Pi-hole servers

Connects to several Pi-hole servers at once to pull or update their custom host file over a secure connection.

How the work actually flows

A straight line. Runs once per each pi-hole server.

The problem it solves

Managing a custom host list across several Pi-hole servers means logging into each one separately to check or update the same file. Doing this by hand for every server adds up fast, and it's easy to lose track of which server has which version. You want one place to pull or push the file across your whole setup.

Who it fits

An IT admin or small business managing DNS filtering across multiple Pi-hole servers.

How it works

  1. You start the check with your list of servers, addresses, and logins
  2. The system connects to each Pi-hole server over a secure connection
  3. It retrieves or writes the custom host file on each server in turn
  4. Results from every server come back so you can confirm they're in sync
What you get

Pi-hole servers you know are in sync

You can pull or update the host file on every Pi-hole server you manage from one place, all at once.

What you get

An up-to-date, synced custom host file across every Pi-hole server you manage.

What you need

SSH access and login credentials for each Pi-hole server.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.
