[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=1on Proxmox vmbr0 (via sysctl.d) + createdstatic-arp.serviceon UDev pinning all 4 LXC container IPs to permanent ARP entries - Next: N/A, resolved
