# Ubuntu-SVR (192.168.0.252)

Local mini PC — Frigate NVR, Omada controller, Coral TPU.

## Network

## SSH Access

From kaburuaibox, use this key: ``` ssh -i ~/.ssh/id_ed256 [email protected] ```

⚠️ CRITICAL: Do NOT use `/opt/hermes/config/hermes_shell_id_ed25519` for ubuntu-svr. That key is for TrueNAS only. It will fail with ubuntu-svr.

The correct key is `/home/kaburu/.ssh/id_ed256` (411 bytes, RSA).

Via Tailscale: ``` ssh -i ~/.ssh/id_ed256 [email protected] ```

## Services

- Frigate — NVR (v0.17.1) - Omada Controller — network management - Coral TPU — edge AI inference - Open WebUI — web interface - Portainer — Docker management - Uptime Kuma — uptime monitoring

## Known Issues

- No Fail2Ban (LAN-only, behind OPNsense firewall) - SSH key auth only (no password auth) - Previously had key mismatch issues — fixed 2026-06-03

## Notes

- Ping works (unlike OPNsense which drops ICMP) - SSH from LAN only (not exposed to internet) - Tailscale SSH also works
