rtty(中文)

A reverse proxy WebTTY. It is composed of the client and the server. The server is written in go language and uses the vue+iview. You can access any of your terminals through a web browser based on the device ID you set(If the ID is not set, the MAC address of the device is used).

rtty is very suitable for remote maintenance your or your company's thousands of Linux devices deployed around the world.

Dependencies for Client side

libubox - C utility functions for OpenWrt, but can also be used for the same purposes in other Linux systems. Reference
libuwsc - A Lightweight and fully asynchronous WebSocket client C library based on libubox for Embedded Linux.
ustream-ssl - If you need to support SSL
mbedtls - If you choose mbedtls as your SSL backend
CyaSSl(wolfssl) - If you choose wolfssl as your SSL backend
openssl - If you choose openssl as your SSL backend

Deploying the server side

Install the GO language environment (if you haven't installed it)

sudo apt-get install golang     # For Ubuntu

sudo yum install golang         # For Centos

Set GOPATH environment variable(if you haven't set it)(since Go 1.8, default is $HOME/go)

export GOPATH=$HOME/go

Install rtty server

go get -u github.com/zhaojh329/rttys

Manual run

$GOPATH/bin/rttys -port 5912

Install the automatic boot script(debian/ubuntu)

cd $GOPATH/src/github.com/zhaojh329/rttys
sudo ./install.sh
sudo /etc/init.d/rttys start

How to build and install the Client - rtty

For Linux distribution, such as Ubuntu and Centos

Install build tools

sudo apt install gcc cmake git      # For Ubuntu

yum install gcc cmake git           # For Centos

Install dependent packages

sudo apt install libjson-c-dev      # For Ubuntu

sudo apt install json-c-devel       # For Centos

git clone https://git.openwrt.org/project/libubox.git
cd libubox && cmake -DBUILD_LUA=OFF . && sudo make install

git clone https://github.com/zhaojh329/libuwsc.git
cd libuwsc && cmake -DUWSC_SSL_SUPPORT=OFF . && sudo make install

Install RTTY

git clone https://github.com/zhaojh329/rtty.git
cd rtty && cmake . && sudo make install

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'

Query online devices

curl http://your-server:5912/devs
[{"id":"My-device-ID","description":"My device"}]

For Embedded Linux Platform

You need to cross compiling by yourself

For OpenWRT

Install

opkg update
opkg list | grep rtty
opkg install rtty-nossl

If the install command fails, you can compile it yourself.

Configuring the server parameter

uci add rtty rtty   # If it's the first configuration
uci set rtty.@rtty[0].host='your server host'
uci set rtty.@rtty[0].port='your server port'

You can customize an ID for your device. If the ID is not configured, RTTY will use the MAC address of the specified network interface as the ID. The format of the MAC address as the ID is: 1A2A3A4A5A6A

uci set rtty.@rtty[0].id='your-device-id'

You can add a description to your device

uci set rtty.@rtty[0].description='My device'

Save configuration and apply

uci commit
/etc/init.d/rtty restart

Usage

Query online devices: http://your-server-host:5912/devs

Use your web browser to access your server: http://your-server-host:5912, then enter the id of the terminal you want to access, and then click the connection button

You can easily embed RTTY into your existing platform: http://your-server-host:5912?id=your-id

Automatic login: http://your-server:5912/?id=device-id&username=device-username&password=device-password
