Robot DNS server died

My secondary DNS server died after four years of service. The DNS has 118 host records, and 45 of those records are for my VMware Cloud Foundation Server.

Atomic Pi DNS server – RIP

The Atomic PI – Intel PC was designed for a home robot that never made it to market. In 2019 I put it in service running Ubuntu Linux, providing BIND and NTP for my home. It was an experiment with a $35 PC, $4 plastic Walmart case, and a $9 power supply from Amazon which was an unheard-of price point in 2019.

Dell/Wyse 3040 Thin Client PC Replacement

I replaced the DNS server with a used $39 Dell Wyse 3040 thin client PC from eBay, which is typically used for VDI with a VMware Horizon client or Citrix Virtual Desktops. I’ve been pleased with the first Wyse 3040 I use as an amateur radio repeater/hotspot. The hardware specs are similar to the Atomic PI, and I splurged for twice as large 16GB flash storage model. It’s smaller and comes in a real case.

UEFI Challenge

The thin client PC requires UEFI, which requires an additional step to install the operating system. I used Ventroy to build the usb drive image with UEFI.

Ventroy to build USB boot image for Ubuntu Linux

Ventroy is a 2-step process. First, Ventroy will prepare the USB drive and create an empty partition. The second step is to copy the Ubuntu image into the empty partition. I was able to take the USB drive I prepared with Ventroy and boot Ubuntu Linux and deploy it. After installing and configuring BIND, my secondary DNS server is up and automatically replicating entries from my primary DNS.
