Sending emails from an IPv6-only host

I have a cheap IPv6-only VPS which hosts a website using CloudFlare’s reverse proxy providing IPv4 connectivity. The VPS also has IPv4 connectivity through a public NAT64 service, which uses a NAT gateway to send packets to an IPv4 destination by embedding the IPv4 address in the v6 address. But sending emails is another ball game. I can’t send emails directly from the host as most email providers do not have IPv6 connectivity right now.

Isso multisite using Docker

This is probably going to be a short and sweet post. I was trying to set up Isso, since I didn’t really like Remark42. As always, I was going with the Docker install option, but I kept running into issues setting up multisite - I needed one Isso instance to provide commenting for all of my Hugo sites. After one Github issue, which really should have been a Discussion - but I thought I had encountered a bug, it was pointed out that I needed run Isso with isso.

Creating a 503 error page server with Nginx

I needed to serve a custom 503 page for every request to any URL for a domain, and since we serve things using Traefik, I needed a backend service which served the same 503 image for any request. The vhost configuration for Nginx ended up being like this - server { listen 80; server_name localhost; #access_log /var/log/nginx/host.access.log main; root /usr/share/nginx/html; # Convert all error codes to 503 and specify file error_page 404 500 502 503 504 =503 /index.

Unbricking the NanoPi R6S

TL;DR - Run upgrade_tool UL MiniLoaderAll.bin in Maskrom mode. I recently obtained a NanoPi R6S with the intention of turning it into a router powered by OpenWrt. Everything seemed to be going swimmingly well until I tried to expand the SquashFS OpenWrt partition on the internal eMMC storage, and that seemed to brick the device. Every time it was turned on, the red SYS light would stay solid instead of blinking after a bit - that meant it was stuck in the bootloader phase.

Sandisk Industrial SLC MicroSD Card Review

This is a straightforward, possibly barebones review of the 32 GB Sandisk Industrial Grade Extended Temperature IX QD334 microSD card (SDSDQED-032G-XI). I have had several high endurance (and max endurance, whatever that means) microSD cards fail on me over years of use in Raspberry Pis and dashcams, so I decided to splurge the cash and get an SLC microSD card with an industrial-grade controller that’ll probably last me a lifetime.

Traffic Advice configuration for Nginx

If you have been seeing 404s for /.well-known/traffic-advice in your access logs from the Chrome Privacy Preserving Prefetch Proxy bot, you’re not alone. It’s Google Chrome’s private prefetch proxy intended to decrease the Largest Contentful Paint (LCP) performance metric for faster perceived page loads. There are a few guides (including the first answer on the Stack Overflow question I linked earlier) to have your web server respond correctly to these requests.

Deploy to Cloudflare Pages with Gitlab CI

Cloudflare Pages is an amazing service to host your SSG and static HTML websites on edge locations and serve pages with low latency around the world. However the product is still new and isn’t as full-featured as I’d want it to be. One of the deficiencies is the lack of deployment options - only GitHub and GitLab.com hosted repositories are supported seamlessly - for anything else, we need to use Wrangler or directly upload a folder or a Zip file through the Cloudflare dashboard GUI.

Hugo Subscript and Superscript Shortcodes

In its current avatar, there’s no way to get superscript or subscript text in your Hugo content without directly embedding <sup> or <sub> tags in your posts and setting unsafe: true in the Goldmark renderer settings in config.yaml. A cleaner alternative is to use shortcodes to embed these tags in the content. This keeps us from having to enable HTML tags in all posts, and we can have our Markdown content files looking mostly clean.

Add a Canonical URL tag to your Hugo site

While working with a barebone Hugo theme, I noticed that it doesn’t have a canonical URL meta tag. I have a publicly accessible development site because of the inticracies of my deployment procedure, and it is quite important that it is not picked up and indexed by search engines. Canonical URLs become really important in this context. Well, thankfully it was really easy to add. I needed to override the template file that defined the <head> section of our pages.

Monitoring a process for high memory consumption using Monit

I run Pi-hole on an old PogoPlug E02 with a custom compiled dnsmasq (or pihole-FTL, as they now call their customised version of it). Lately I have been noticing my DNS queries becoming slow erratically, and upon further investigation it looked like pihole-FTL has a memory balloon, and it consumes all of the 256 MBs of memory available and starts swapping, bringing everything to an almost standstill. In comes Monit, a highly configurable process supervisor.
