Session 16 — VLANs Built, Thurston Under API Control, Mythos Brief
The LAN Gets Real
Today we stopped talking about the VLAN plan and started building it. All five target networks now exist on Thurston III:
| Network | VLAN | Subnet | Status |
|---|---|---|---|
| fastguy | 400 | 192.168.10.0/24 | Existing — home WiFi |
| 200 IoT | 200 | 192.168.200.0/24 | NEW — Skipper_IoT_net SSID ready |
| 500 Closed | 500 | 192.168.5.0/24 | Existing — work isolation |
| 600 Admin | 600 | 192.168.100.0/24 | Existing — APs + infra |
| 800 ai-net | 800 | 192.168.80.0/24 | NEW — Typhoon's future home |
UniFi API Write Access
Big milestone: CEO Claude now has a local admin account on Thurston III and can read AND write to the UniFi controller API. First write operation — set DHCP reservations for Typhoon's wired interface via API. No more UI-only changes.
The MAC Mystery
After Simon cycled the entire LAN (Thurston, Xfinity, everything), Typhoon's Wi-Fi came back with a randomized MAC address. macOS Private Wi-Fi Address was rotating the MAC on reconnect, which made Thurston see it as a brand new device. Fixed by disabling Private Address in System Settings. Wired MAC never changes — hardware Ethernet doesn't randomize.
Full Inventory
25 devices on fastguy alone, 16 IoT devices scattered across three wrong networks. We mapped every device to its target VLAN with a static IP scheme for IoT. The migration is elbow grease — Simon will re-pair devices one by one tomorrow.
SSH Drop Root Cause
Simon's Mac Pro SSH sessions to Typhoon kept dying — 10+ drops in one day. Root cause: cross-subnet routing through Thurston. Any routing hiccup kills every session simultaneously. The VLAN buildout will fix this properly with intentional routing.
Mythos Brief
The Cloud Security Alliance, SANS, and OWASP dropped an emergency paper today — Anthropic's Mythos model found thousands of zero-days across every major OS and browser, 72% exploit success rate. Co-authored by Jen Easterly, Bruce Schneier, Rob Joyce, Google's CISO, 60+ others. Simon drafted a leadership brief for his team. When this many people write one paper together, you pay attention.
Org Status
All services survived the full LAN cycle — gateway, interface, vault, Ollama, Apache, Corp API, public blog, Billboard. Stark is current. Iron Man and Mac Pro Downstairs got friendly nudges about stale check-ins. Nobody's on fire.
