Overview

rtty is a remote access solution composed of device clients and the rttys server. This repository contains the C client; rttys provides the web interface and relays connections to devices. Open a terminal, transfer files, and access device services through a central server.

Client Implementations:

• C Client: Ultra-lightweight, designed for embedded Linux and resource-constrained devices.
• Go Client: Easy cross-platform compilation, suitable for rapid integration and deployment.

The server is implemented in Go, with a modern frontend built using Vue.

Both browsers and device clients must be able to reach the server. Clients initiate connections to it, so devices behind NAT do not need public IP addresses or inbound port forwarding. Access devices through your browser and identify them by device ID and group.

Use rtty to maintain OpenWrt routers, troubleshoot embedded Linux gateways, or manage distributed Linux devices remotely.
