Router-sized 4096-entry rings on every port with GRO kept across forwarding, the IOMMU in passthrough mode, and EEE pinned off on the I226-V ports as one trigger for their link-drop erratum. The ring and GRO settings are .link files, so they land on a device add event rather than at switch time. Also document the tuning deliberately not done -- coalescing and PCIe ASPM -- and what measuring the NICs' ESP offload found, since the esp4_offload modules are software batching and easy to mistake for it.

colony
The hosted dedicated server in Amsterdam (ams1) and the public-facing half of
the boxes: almost everything reachable from the internet lives here.

Networking
colony separates the host, VMs, shill containers and whale2 OCI workloads onto dedicated
networks behind estuary, which terminates the public addressing. The canonical
prefixes and routing overview are in the colony section of networking.md.
Boxes
| Box | Role |
|---|---|
colony |
Physical VM host (AMD, KVM, LVM-thin, borgthin backups → rsync.net) |
estuary |
Edge router: WAN, firewall/NAT, DNS, BGP (AS211024), WireGuard |
shill |
NixOS container host (most applications; per-container pages under shill/) |
whale2 |
podman/OCI game-server host |
git |
Gitea + Gitea Actions runner |
mail |
Debian VM running mailcow (not NixOS) |
darts |
Third-party/customer VM (not NixOS) |
portcullis |
Bare-metal edge box for Nikhef; being staged, not yet in service |
The applications running on shill are listed on its own page — see
shill/README.md.
mail and darts are host-defined VMs whose guest operating systems are managed out of band; their
pages document only what this repository controls.
portcullis is new hardware headed for Nikhef that will take over most of estuary's edge routing.
It is not deployed yet and the resulting topology is still being worked out. It travels with
fergal, an OpenWrt SFP+ switch whose firmware this flake builds; both are staged at
home for now, borrowing the home fabric through
jim.
