Annoyed with the internet ads? Host a local DNS ad-blocker on your home lab to block ads on all the devices in your home network.

In this fourth post on the home lab series we cover hosting Plex media server on home lab. It also talks about how to create partitions on your storage disk, mount it & how to share it as an NFS directory.

In this third post on home labs I install OS on the machines in my home lab. I also install K3s cluster on it making it ready to host applications.

In this post I assemble all the hardware components for the machines in my home lab. I also configure my home network to separate them from other devices in my home for security purposes.

I recently came across the concept of Home Lab & I thought of giving it a try. Follow along as I learn what it is, things to consider while setting it up & the way I set up my Home Lab.
