It is composed of a client and a server. The client is written in pure C. The server is written in go language and the front-end is written in Vue.
You can access your device's terminal from anywhere via the web. Differentiate your different device by device ID.
rtty is very suitable for remote maintenance your or your company's thousands of Linux devices deployed around the world.
Features
- The client is writen in C language, very small, suitable for embedded Linux
- No SSL: rtty(32K) + libev(56K)
- Support SSL: + libmbedtls(88K) + libmbedcrypto(241K) + libmbedx509(48k)
- Execute command remotely in a batch of devices
- SSL support: openssl, mbedtls, CyaSSl(wolfssl)
- mTLS
- Very convenient to upload and download files
- Access different devices based on device ID
- Support HTTP Proxy - Access your device's Web
- Fully-featured terminal based on Xterm.js
- Simple to deployment and easy to use
Dependencies of the Client side
- libev - A full-featured and high-performance event loop
- mbedtls(polarssl) or CyaSSl(wolfssl) or openssl - If you want to support SSL

How to run rtty
Replace the following parameters with your own parameters
sudo rtty -I 'My-device-ID' -h 'your-server' -p 5912 -a -v -d 'My Device Description'
If your rttys is configured with mTLS enabled (device key and certificate required), add the following parameters(Replace the following with valid paths to your own)
-k /etc/ssl/private/abc.pem -c /etc/ssl/certs/abc.pem
You can generate them e.g. via openssl tool openssl req -x509 -newkey ec -pkeyopt ec_paramgen_curve:secp521r1 -keyout /tmp/key.pem -out /tmp/cert.pem -days 18262 -nodes -subj "/C=CZ/O=Acme Inc./OU=ACME/CN=ACME-DEV-123"
If your rttys is configured with a token, add the following parameter(Replace the following token with your own)
-t 34762d07637276694b938d23f10d7164
Usage
Use your web browser to access your server: http://your-server-host:5913, then click the connection button
connect devices with no web login required(you need to configure the device white list on the server)
http://your-server-host:5913/connect/devid1
http://your-server-host:5913/connect/devid2
Transfer file
Transfer file from local to remote device
