[Claude Code] Session Checkpoint

  • Asked: Plex wasn't working; then how to prevent it recurring
  • Root cause: UDev had stale ARP entry for 192.168.86.73 pointing to Finn's physical NIC MAC instead of the container MAC
  • Fixed: Enabled arp_notify=1 on Proxmox vmbr0 (via sysctl.d) + created static-arp.service on UDev pinning all 4 LXC container IPs to permanent ARP entries
  • Next: N/A, resolved
