Our Mastodon instance "burningboard.net" now internally **ONLY** uses the Internet Protocol in Version 6. I did successfully migrate away from any RFC1918 addresses in any of the internal infrastructure connections. Nginx -> Mastodon: IPv6 Mastodon -> PostgreSQL: IPv6 Mastodon -> Opensearch: IPv6 Mastodon -> Sidekiq: IPv6 Mastodon -> Loki: IPv6 Sidekiq -> PostgreSQL: IPv6 Prometheus -> Mastodon: IPv6 All using globally routed unique addresses and proper routing and packet filtering from "pf" (FreeBSD). Outbound connections to legacy hosts (for example for Federation) uses NAT64 over Tayga. Inbound the Nginx is the only component, that supports IPv4 on NAT on a best-effort approach. But I refuse to put a lot of work into this. We have 2026 and it's a dying, smelly protocol, that I don't even monitor anymore. If someone looks at the Firewall rules.. Yes, we do run a (private) Factorio Server on our Mastodon system :factorio: #mastodon #mastoadmin #ipv6 #networking #freebsd @tux@burningboard.net

Okay, this is weird. I am seeing `tailscaled` spiking up to 250% CPU usage every other minute, with up to 60 MBit/s outgoing traffic on the `tailscale0` interface... and on the `wg0` interface I see the same amount of traffic during that period. I now disabled wireguard and the issue is gone. But I have absolutely NO idea why this is happening, what causes it, and why it (seemingly) suddenly started - I did not have this issue earlier today. All I did in between was update the unstable channel, but all packages involved here (tailscale, wireguard) are from stable. So... 🤔 I am at loss... #tailscale #wireguard #linux #linuxnetworking #networking #sysadmin #nixos

New series: FreeBSD Foundationals Part 1 is about Jails - specifically VNET Jails. What epair interfaces actually are (virtual ethernet cables), how bridges tie them together, why the host is basically a router for your jails, and what devfs rulesets control. Covers the full lifecycle from jail.conf through pf firewalling with NAT/RDR for IPv4 and direct routing for IPv6. Plus the gotchas that'll cost you hours if nobody warns you. Not a beginner tutorial, hardcore details. The useful middle. https://blog.hofstede.it/freebsd-foundationals-jails-from-chroot-on-steroids-to-full-virtual-networks/ #Unix #FreeBSD #Networking #Jails #DevOps #SelfHosting #Sysadmin

I just published a new guide on evolving a single BGP router into a multi-homed, two-PoP network using FreeBSD, FRR, and PF. - Native peering on Vultr + 3 GRE transits - Tying it together with iBGP - Why stateful firewalls break asymmetric transit (and how to fix it) All for ~€18/mo. Read it here: https://blog.hofstede.it/running-your-own-as-going-multi-homed-with-ibgp-and-three-transits/ #FreeBSD #BGP #IPv6 #Networking #Sysadmin #FRR #Homelab

Got my AS201379 (2a06:9801:1c::/48) well connected to European networks. RIPE Atlas measurements are pretty satisfying now 🙂 My website (hofstede.it / blog.hofstede.it) is reachable in <10ms from most of Europe via my own address space. - 4 Upstream providers - Two BGP routers - Stable for > 48hrs and reasonable ingress and egress paths 🙂 Very, VERY pleased with the result! Next stop: Own NAT64 setup 🙂 Big thanks to @UnderEu@mas.to , @tschaefer@ipv6.social and @Hypopheralcus@det.social for giving me the Atlas credits for Measurements! Highly appreciated! #ipv6 #networking #it #ripe #bgp

Any chance that someone might have a leftover RIPE ATLAS credits? I currently do some experiments with the IPv6 routing of my AS201379 and being able to do measurements on Atlas would be sooooo helpful right now. #fedihelp #ripe #ripencc #ripeatlas #ipv6 #networking

Spent way too long getting HTTP/3 working on FreeBSD with nginx, so I wrote it all up. The highlights: stock OpenSSL silently breaks QUIC at the HTTP/3 framing layer (the TLS handshake succeeds, so openssl s_client lies to you). eBPF worker routing doesn't exist on FreeBSD. And if nginx is in a jail with IPv4 NAT, a pass rule for UDP 443 is useless without a matching rdr.
