Reticulum is a cryptography-based networking stack for building sovereign, resilient local and wide-area networks that work even under high latency and extremely low bandwidth. It has no central control, no kill-switches, and gives every participant full ownership of their own network segments.
Add this interface to the [interfaces] section of your Reticulum configuration:
[[Septal Net]] type = TCPClientInterface enabled = yes target_host = rns.septal.net target_port = 4242
