DEF CON 33 - RF Village - Meshtastic Command & Control - Eric Escobar

This presentation will detail the design and implementation of a Meshtastic-based command and control infrastructure. By leveraging the Meshtastic network for out-of-band communications, operators can achieve secure, decentralized monitoring and management of Linux hosts in hard-to-reach environments. Whether supporting a remote dropbox deployment or a distant ham shack, this solution enables encrypted shell access and configuration changes using a low-cost ($25) LoRa radio over extended ranges. Although not intended for high-bandwidth tasks, it provides an efficient platform for debugging, troubleshooting, and command execution in constrained network conditions. Furthermore, by utilizing the existing Meshtastic mesh, users can often avoid the complexity of building a dedicated network.
