OAM: Fleet-wide Linux access + naming audit (Saturday prep)
100%
Description
Audit every Linux machine on the tailnet (physical + virtual): (1) tailscale hostname / Proxmox VM name / knel.net DNS record all match, (2) SSH login works with the expected user (localuser most systems, root on Proxmox, subodev on Pis + Jetson), (3) root escalation (passwordless sudo) works. Deliverables: reusable audit script scripts/audit-fleet.sh (committed), failure report, ticket note with results. Read-only audit — no changes to any system.

Audit complete 2026-08-26. 75 Linux machines on tailnet (74 peers + workstation). DNS: 74/74 peers resolve correctly (1 workstation self-record wrong: ultix-streaming.knel.net -> 127.0.1.1). SSH: 54 OK / 19 FAIL / 1 offline (stlp-3dscanner since Feb). Root escalation verified on all 54 reachable. 5 name mismatches (appliance-driven: homeassistant/pfv-bms, umbrel/tsys-umbrel, ultixfield/ultix-field, sectestbed-hfnoc/-uisp, tsys-cloudron-new). 10 of 19 SSH failures are Proxmox/UCS appliance VMs with no localuser (PDM/PMG/PBS/UCS) - decision needed on appliance access standard. Full report: https://community.turnsys.com/t/312. Script committed: scripts/audit-fleet.sh. Related: #447 (Rundeck) created for future fleet automation.

Naming convergence complete 2026-08-26. Convention confirmed fleet-wide: sectestbed-|preprod- + bare/tsys-/pfv- (prod). Resolved: VM 51012 guest renamed to sectestbed-hfnoc-uisp (UISP lineage now fully consistent at all 3 tiers); duplicate DNS ultixfield.knel.net deleted (canonical ultix-field; stale netinfra-01 cache entry expires by TTL ~1h — zone store + netinfra-02 clean). Scope: tsys-cloudron-new/tsys-cloudron excluded from all audits (prod revenue VPS); homeassistant + umbrel by-design no-SSH. Final audit v2: 54 OK / 16 SSH fail (key deploys + appliance access decision) / 2 by-design / 1 offline (stlp-3dscanner). Script updated + committed (07ad445). HFNOC GIS/app lineage (zero footprint) proposed in #448. Audit log: Discourse #298; report + resolution: #312; inventory correction: #307.

Root-access probe on all former localuser-fails: 13/16 accept root (Proxmox appliances, stlpc via labuser-era model, jetson, ultix-field). pfvsvrpi confirmed localuser+sudo (it is a localuser fleet box, not subodev). Score now 65 OK / 5 fail / 2 by-design / 1 offline. Remaining fails are interactive-only: sectestbed-sandbox (localuser key), tsys-ucs-01/02 (no agent-accessible user), pfv-jetson-nano-1 (subodev key deploy, root already works). Script corrected + committed (8a6a985). Report thread: https://community.turnsys.com/t/312

Scope final: stlp-3dscanner and sectestbed-sandbox removed from audit (sandbox is a disposable break-fix VM rolled back via Proxmox; 3dscanner long-offline, user pulled it). Remaining known failures: tsys-ucs-01/02 (root key push — user pushing via ZOC now) and pfv-jetson-nano-1 (subodev key). Effective score with final scope: 65 OK / 3 fail / 2 by-design.

pfv-jetson-nano-1 confirmed localuser + passwordless sudo (key pushed via ZOC). FINAL: 68 OK / 0 fail / 2 by-design-no-SSH (homeassistant, umbrel). Audit complete across all in-scope systems. Script final state committed (audit-fleet.sh).

Naming convergence COMPLETE. User applied Tailscale admin renames (pfv-bms, tsys-umbrel); MagicDNS serves canonical names; audit keys on MagicDNS name (a01c916). Final: 67 OK / 2 by-design / 1 transient (kali-tsys TS presence flap, SSH verified). Four-way alignment (VM/DNS/Tailscale/OS hostname) holds across entire in-scope fleet — zero mismatches. Out of scope: tsys-cloudron + netbird (Reston VPSes), stlp-3dscanner, sectestbed-sandbox. Full narrative: https://community.turnsys.com/t/312
