Sysadmin's Corner at Michiru

Hey, come on in, how are you doing? Not many pop in here. I've just done a pot of coffee, feel free to pour yourself a cup. =w=

This page has some notes and information about the server :)

Tech Specs

Michiru is running on a BuyVM Slice 2048 in Switzerland. It has 512GB of additional block storage attached for media storage. It runs Alpine Linux as the base image, and all services run in Docker, except for a Tailscale node, DNS, and the backup and email systems.

Networking

Michiru is exposed to the public internet via Caddy, a HTTP, HTTP/2, and HTTP/3 server. All response traffic supports gzip and zstd compression.

Michiru is exposed to the public internet, dual-stack, as 107.189.3.111 and 2605:6400:30::1. It is also connected to various devices via a tailnet.

I self-host a Headscale instance, which provides the tailnet control and DERP infrastructure. It also is responsible for DNS configuration of all my devices, and my DNS traffic travels exclusively through Tailscale.

This server has many domains pointing at it, but generally, michi.tel is the main domain, with many subdomains. michiru.yellows.ink was the old domain before that, michiflare.yellows.ink points to Michiru via Cloudflare's proxy. A few subdomains on my own doman and on uwu.network also point to this server.

Services

A service list is on the home page, no guarantees its up to date or complete though.

I do not operate any open proxies on Michiru. All CONNECT requests will be ignored, and the SOCKS proxy is authenticated. You may try using prox.yellows.ink for an open HTTP-based proxy service (you cannot use this in your browser as a real HTTP proxy).

Stability

Uptime is generally high, and I have a monitoring setup for services, though I have no monitoring for if a container is alive but broken, or if Michiru is inaccessible to the public internet. Docker will restart any downed services, so if something is down, it was intentional, a result of a backup failure, or something is repeatedly crashing. Backups are automatically taken every day at 4am (Europe/London timezone), by Restic and ResticProfile. They include all service data and configuration, but not jellyfin media and torrent data, as that is too large. They are stored in a secure Backblaze B2 bucket.

Emails

Michiru may send automated emails. These are generated with some custom scripts written by yours-truly.

Emails from Michiru will never be unsolicited, and will always come from michiru@riseup.net, michiru@yellows.ink or system@michi.tel.

This inbox is monitored. Automated emails will be marked with the following footer:
This email was automatically generated at [DATE] by Hazel's magic email scripts:tm: on Michiru.
All human-written emails from this mailbox will be clearly signed off by a person (usually "- Hazel").

Thanks for stopping by! Check my website out here and my good friends at UWU.NETWORK here. (note: this server is unrelated to uwunet.)

Oh hey, wait up! Don't forget your coffee!
