Personal infrastructure notes.
|
||
|
||
- [`nuc/`](nuc/) — home lab on `nuc` (see below)
|
||
- [`ks4/`](ks4/) — prod server `ks4` at OVH (see below)
|
||
- [`ks2/`](ks2/) — legacy backup server being decommissioned
|
||
(rental ends Sep 30, 2026): [plan](ks2/plan.md)
|
||
- [`archer-c7/`](archer-c7/) — home router (TP-Link Archer C7 v5,
|
||
OpenWrt, `192.168.0.2`, WAN = phone USB tether):
|
||
[upgrade to 25.12](archer-c7/upgrade-openwrt-25.12.md)
|
||
|
||
## Homelab: nuc
|
||
|
||
Incus host on the LAN.
|
||
|
||
- Host: `nuc` — `192.168.0.3`, Debian 13, Intel Alder Lake-N
|
||
(iGPU `i915`, shared by both Jellyfin containers) —
|
||
bare-metal reinstall: [nuc/nuc-install.md](nuc/nuc-install.md)
|
||
- SSH: `ssh -i id_rsa_claude root@192.168.0.3` (keys at repo root, gitignored)
|
||
- Instances are bridged onto the LAN (192.168.0.0/24)
|
||
- USB 4 TB WD Red: ZFS pool `usb4t` — `usb4t/backup` → `/backup`
|
||
(incus exports, `nuc/` + `ks4/` subdatasets, 1 TB quota) and
|
||
`usb4t/media` → `/srv/media` (media library, shared into containers
|
||
via `shift=true` disk devices; works because ZFS ≥ 2.2 supports
|
||
idmapped mounts)
|
||
- NAS: `//192.168.0.10/Shared` (CIFS) — original media source, normally
|
||
offline; not mountable into containers (idmapped mounts unsupported
|
||
on CIFS)
|
||
- Backups: all local instances replicated to the USB pool
|
||
(`/root/scripts/incus-copy.sh -p backup -s nucbackup`; replicas
|
||
stopped, autostart off) — see
|
||
[nuc/nuc-install.md](nuc/nuc-install.md); ks4 replicas pulled into
|
||
pool `ks4backup` — see [ks4/incus-copy.md](ks4/incus-copy.md)
|
||
|
||
### Instances
|
||
|
||
| Name | IP | Doc | Features |
|
||
|---|---|---|---|
|
||
| [jellyfin-server](nuc/jellyfin-server.md) | 192.168.0.5 | ✅ | unprivileged, autostart; iGPU render node (`gpu` device, render gid) for QSV/VAAPI transcoding; `/srv/media` disk device (`shift=true`); proxy device → host :8096 |
|
||
| [jellyfin-client](nuc/jellyfin-client.md) | 192.168.0.6 | ✅ | **privileged**, autostart; full iGPU (`gpu` device, gid 44) → HDMI kiosk (cage + Jellyfin Media Player); custom `raw.lxc` (bind `/dev/snd`, `/dev/input`, host `/run/udev`); Pioneer USB audio as ALSA default; FR keymap; go-librespot Spotify Connect ("Pioneer A-70") |
|
||
| [transmission-bt](nuc/transmission-bt.md) | 192.168.0.7 | ✅ | unprivileged, autostart; always-on WireGuard full tunnel → ks4 (egress = 193.70.35.17, kill switch: no default route); `/srv/media` disk device (`shift=true`), downloads to `/media/downloads`; web UI :9091 (LAN only) |
|
||
| blocky | 192.168.0.254 | — | unprivileged, autostart; DNS ad-blocker |
|
||
| privoxy | 192.168.0.11 | — | unprivileged, autostart; filtering HTTP proxy |
|
||
| homeassistant | (stopped) | — | **virtual machine**, 50 GiB root disk on pool `data` |
|
||
|
||
## Prod: ks4
|
||
|
||
Incus host at OVH — public-facing self-hosted services.
|
||
|
||
- Host: `ks4.lutran.fr` — `193.70.35.17`, **SSH on port 2233**,
|
||
Debian 13, Xeon D-1521 / 32 GiB, 2× 6 TB (OS on mdraid RAID1,
|
||
ZFS pool `data` on `sda5`) — setup & rebuild:
|
||
[ks4/install.md](ks4/install.md)
|
||
- SSH: `ssh -i id_rsa_claude -p 2233 julien@193.70.35.17`
|
||
(`julien` has passwordless `sudo incus …`)
|
||
- Instances are on a NAT bridge `incusbr0` (192.168.1.0/24); public
|
||
ingress via Incus proxy devices. `gateway` (nginx) is the sole HTTP/S
|
||
entry point and fans out to the app containers.
|
||
- Services: gateway, mail, nextcloud, seafile, git, freshrss, bitwarden,
|
||
outline, login (SSO), wireguard, + more — full table in
|
||
[ks4/install.md](ks4/install.md).
|
||
- ⚠️ The ZFS `data` pool is single-disk (not mirrored); durability
|
||
rests on nightly root cron jobs — 01:00 `incus copy --refresh` of
|
||
all instances to the local `backup` pool on sdb5
|
||
([ks4/local-backup-cron.md](ks4/local-backup-cron.md),
|
||
[ks4/incus-copy.md](ks4/incus-copy.md)), 04:30 plakar backups
|
||
(DB dumps + data trees) to S3
|
||
([ks4/plakar-s3-data.md](ks4/plakar-s3-data.md)), plus during the
|
||
transition a 04:00 rsync stopgap to ks2
|
||
([ks2 decommission plan](ks2/plan.md)); a pull leg to nuc pool
|
||
`ks4backup` awaits FTTH.
|
||
|

|
||
phones/laptops: WG peers 10.8.0.2-3 reach 192.168.1.x through the same endpoint
|
||
```
|
||
|
||
Both tunnels initiate **from** nuc (home NAT, dynamic IP) toward ks4's
|
||
fixed endpoint; ks4's incus API is never exposed to the internet.
|
||
|
||
### Conventions
|
||
|
||
- One markdown file per instance in `nuc/`, containing the full
|
||
install script (idempotent-ish, run as root on the host), first-run
|
||
configuration, and troubleshooting notes.
|
||
- Containers are built from `images:ubuntu/24.04` and configured
|
||
exclusively through `incus exec`/`incus config` so the doc is the
|
||
single source of truth — rebuilding = re-running the script.
