Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

I have a few animal breeding projects that my wife and kids are into heavily, and one specific project that's just beginning is Western Hognose Snakes. We have a young male Axanthic Western Hognose that we named Gene (work with me on this, they're pets as well as breeders!). Gene is in a bit of a large enclosure for a snake his size, complete with lots of substrate to rummage around through, live plants, and a few hiding places. He's a super happy snek.

So here's the issue: Western...

Hashicorp Vault on OpenBSD-6.9 CURRENT

Posted 07-19-2021 at 10:06 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

At $DAYJOB, I'm in a position of doing crypto related work again, and while not quite as in depth as the HSM work I did in previous jobs, it's still fun. One of the core components I'm tasked with being an expert on is Hashicorp Vault (which I've used in previous jobs, but I've not been in a position of administration before now). I've learned over the years that if you want to become familiar with a software system quickly, you need to build it on OpenBSD. Why? Because 1) I like OpenBSD (ok,...

multi-arch kubernetes on amd64 and arm64 with Raspberry Pi 3B+s

Posted 09-22-2019 at 05:24 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

There's a bug in the go runtime that prevents etcd from working properly on armv7l devices. Calico and Helm/Tiller don't run on armv7l. And as I mentioned in my last post, Docker images are *really* limited on arm32v7 platforms. Raspbian sadly has not updated to arm64, so I switched the Raspberry Pis over to Debian Buster from here: https://people.debian.org/~gwolf/ras...PREVIEW.img.xz Since the Raspberry Pi 3B+ is actually a 64 bit machine (but...

dnscrypt-proxy on docker on kubernetes on Raspberry Pis

Posted 08-31-2019 at 04:33 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I recently constructed a Raspberry Pi cluster for testing a few distributed systems (ceph, primarily, which failed fantastically due to the 1G memory of the Raspberry Pi 3 B+...I managed to get it *running*, but anytime there was a *recovery operation* the cluster slowed to a halt). More recently I put rak8s on the Pis to test out Kubernetes, using the default Docker backend.

Problem is, arm32v7 Docker images are severely limited, especially compared to what is available on amd64....

acme-client fails with "file exists"

Posted 07-27-2019 at 05:47 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)
Updated 07-27-2019 at 11:58 PM by rocket357

Running OpenBSD-6.5 on a machine with two internet uplinks (shared on a common local network), I noticed that acme-client would die with "file exists" over and over again.

The problem was in how acme works when using http-01. In this mode, acme-client will reach out to the Lets Encrypt endpoints (v2 at the time of this writing) and ask for a certificate. Since it's using http-01, Lets Encrypt will then reach out to the domain the certificate is for (which needs to be the...
