Summary

The hosts document a real-world attempt to rebuild a small office network using Linux-based hardware and OpenWrt. They navigate unexpected hardware failures, bridge instability, and the complexities of managing remote connectivity.

Topics

  • Linux Networking
  • OpenWrt
  • Home Assistant
  • Nebula VPN
  • Network Troubleshooting
  • Open Source Software
  • Embedded Linux
  • IoT Automation

Highlights

  • Main idea: Rebuilding a network around Linux-based hardware to gain full control over the entire stack
  • Failure mode: Unstable network bridges caused by USB power management issues on MiFi connection hardware
  • Practical takeaway: Using LLM-based TUI tools like OpenCode to rapidly correlate system logs and identify kernel-level issues
  • Practical takeaway: Implementing decentralized VPNs like Nebula to establish reliable, bidirectional SSH access
  • Practical takeaway: Utilizing Android tablets with web-view kiosk software as low-cost, dedicated Home Assistant dashboards
