Self-Hosting a Firefox Sync Server
Self-Hosting a Firefox Sync Server
After switching from Firefox to LibreWolf, I became interested in the idea of self-hosting my own Firefox Sync server. Although I had seen this was possible before, I had never really looked into it—until now. I embarked on a journey to set this up, and while it wasn’t completely smooth sailing, I eventually got it working. Here’s how it went. Finding the Right Sync Server Initial Search: Mozilla’s Sync Server Repo I started by searching for “firefox sync server github” and quickly found Mozilla’s syncserver repo.

POSSE rss to mastodon
POSSE rss to mastodon
I want to post more to the blog, and I want to share it out a bit more. There's an indeiweb concept called POSSE, which means Publish on your Own Site, Syndicate Elsewhere. So lets write a script that pulls down my feed, looks as what I've posted so far on Mastodon, and prompts me to share something. Setup Lets start our publish.rb script with some boilerplate fun, including some inline gems so we don't need to cart a Gemfile around all the time.

Using Caddy to keep certificates renewed - Wiki - Caddy Community
Using Caddy to keep certificates renewed - Wiki - Caddy Community
You can use Caddy as an automated certificate manager to keep certificates renewed without having to run an HTTPS server [1]. This way, the certificates can be used by other programs that need them. Caddy’s tls app can be configured without the need for an HTTP server. It can keep certificates renewed. Without additional configuration, assets (certificates, keys, and metadata) are stored in a data directory on the local file system at a location dependent upon your OS. The simplest form is to ...

Vault Audit Logging
Vault Audit Logging
I thought i was done with this series, but there are a few loose ends that I think we can clear up pretty quickly. The most important of which is Audit Logging, because what is the point of a secure secrets tool if you don’t track who does what (or most importantly, fails to do what) with it. Lets jump in! Enabling audit logs Enabling audit logging requires you to tell the vault server that it should use one of the audit “device types” that it offers with the required parameters.

Cloudflare tunnel for IPv6 only connectivity
Cloudflare tunnel for IPv6 only connectivity
Cloudflare offers a powerful tunneling service that allows for a host on a private network to expose a service but retain protection using cloudflares’ powerful CDN tools. At the time of this post that service is a legacy IP first service, but with one minor tweak it can operate with IPv6-only hosts. Meaning one can provision an IPv6-only host, but provide a dual stacked service. If that sounds powerful, that’s because it is.

NATS and Configuration Minions
Introduction Two blogs in one year. Who do I think I am? In all seriousness, thank you for all the feedback on the previous blog. As always, it really means a lot. This one might go a bit sideways, but building something like this has always been on my mind, and I got another spark to get it done while attending AutoCon2. I caught the first half of a talk by Mircea Ulinic from Digitial Ocean.

Enabling EVPN termination with Podman pods as systemd units
Enabling EVPN termination with Podman pods as systemd units
Quick Recap Link to heading This is a follow up to my lengthy EVPN series. In my last post I demonstrated how I managed to have EVPN termination inside Kubernetes nodes, hosting FRR inside a regular network-namespaced pod interacting with the host via BGP through veth pairs. Overcoming the limitations Link to heading I also described how running inside a pod is limiting this architecture and prototype to serve the node’s main interface, because of the chicken egg-y issue of needing the underlay network to allow each node to reach the API server, while at the same time the configuration required to establish the underlay must be retrieved from the API server itself.
