🐛 Access your terminal from anywhere via the web.

rtty(中文)

This project is officially supported by GL.iNet.

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. Distinguish 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

Who's using rtty

• GL.iNet
• Yunlianxin Technology
• One IOT World
• bitswrt Communication Technology

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

Aliasing MAC Addresses

Tottally newbie request, but how about giving the option of setting up a list of "Aliases" for your preferred MAC Addresses.

I took a peek in your code and might be implemented after the instantiation of the Devices Class and adding a little more data to the return of handle_list.

Maybe a method called add_alias that prefills a mac_aliases dict and also the devs dict in Devices class?

The main goal is to load the interface and click your "Aliased" MAC address and start the session.

I suggest putting the root permission check at the later point建议判断root权限放在 getopt后面

rtty -h 的时候提示 Operation not permitted
其实像查看帮助不需要root权限
所以建议将 if (setuid(0) < 0) { 放在getopt后面

I tried the web client from Mac and it works fine but on Ubuntu desktop (Gnome) right click on the mouse brings up the browser's context menu (Inspect Element etc)

I'm using Ubuntu on a Mac but the mouse is a standard USB mouse

remote command example

The Features list remote command execution. How do we execute commands remotely without a terminal session? How do we see the output? And is it possible to execute the same command across all connected clients?

Final question is what if we execute something that produces very long output (that could go on for a minute or so) and what if we execute a command that launches vim or some other interactive process. I mean all outside of terminal session. Trying to wrap my mind around remote commands idea.

WSS support

When I use rtty under Windows Chrome, I got such error:

reproduct steps:

2. start rtty

4. close RTTYS

SegFault in latest main.c::change_winsize

The function main.c::change_winsize segfault, caused by NULL tty.

This is easily reproducible by symlink /bin/login to a shell script that exits immediately without doing anything.

The underlaying sequence appears to be

1. SIGCHLD queued,
2. The window size message queued
3. SIGCHLD processed to destroy the SID
4. change_winsize is called with the destroyed SID.
5. tty pointer thus is null

rtty session corruption at file transmission

Hey,

i have rtty on an openwrt device. I transmitted a bigger file (~16mb) but cancelled the transmission.
This broke the rtty service, and the terminal output was totally corrupted/garbage in rttys. After a reboot, the device also didn't appeared anymore in rttys. (the service still ran on the device)
Only a clean firmware reflash helped. Do you know more about this behaviour?

Cheers,

rtty fails to start on latest openwrt

Hi.
I tested rtty on latest openwrt which was built on buildroot. But it failed to start.
After some digging, I found rtty requires Libuwsc 3.2,
https://github.com/zhaojh329/rtty/blob/master/src/CMakeLists.txt
on the other hand, libuwsc version is 3.3.1 in buildroot.
Can you update the version of rtty ?
Thanks.

can't run in centos

maybe Readme should indicated whether UDP or TCP or both need to be allowed on the specified/default port

When I used it behind nginx, it can't be used as a 'location'. The nginx.conf is like this:

For Windows

Hi Team,

First of all, Congrats and Thanks for this excellent project.
I am looking to compile this for the windows machine. Is there any possibilities for that?

Deb/Rpm package

I'm struggling with the installation of rtty: I managed to compile everything correctly but the first time I tried to launch rtty I got an error of a missing library. I thought: No problem! Let's create symbolic links. This worked for a couple of missing file but then I had to stop because the library libblobmsg_json.so is nowhere to be found, no matter where I link it. This is the error: "rtty: error while loading shared libraries: libblobmsg_json.so: cannot open shared object file: No such file or directory".

I tried by cloning from HEAD but also from the 4.1.1, with both ubuntu 16.04 and debian 9, 64 bit.

Do you have any idea why?

Do you think it would be possible to have a deb package or at least an install script so that everything is taken care of automatically?

Thanks in advance

客户端日志功能存在内存溢出问题

可能所有版本都有这个bug，就是在连接不上服务器的情况下，会出现内存溢出。
如果客户端一开始就能正常连接服务器的情况，内存占用很正常。但是，如果服务端时不时的连接不上就会出现内存被大量占用，并且不释放。

关于客户端定时断开连接的问题

哈喽，想问一下那个有没有支持设置客户端定时断开连接的参数？

Segmentation fault at reconnect by double onclose()?

When the server rttys restarts, the client crashes instead of reconnecting
Is it because of double closing? Or what?

Thank you

an automatic jump function for url

Hello, can you add an automatic jump function,
The url like this "http://XXXXX:port/rtty.html? Id=aaaaaaaa"; if URL includes id and correct, it automatically jumps or not it will stay the page.
I think this will be a great feature when RTTY support is added to the original device management platform.

error while loading shared libraries: libuwsc.so.2.0.1

$ sudo rtty -I 'ubuntu-1710' -h '192.168.0.100' -p 5912 -a -v -s -d 'My Device Description'
rtty: error while loading shared libraries: libuwsc.so.2.0.1: cannot open shared object file: No such file or directory

I got above error..
I have updated my system curl to latest
curl 7.59.0 (x86_64-pc-linux-gnu) libcurl/7.59.0

建议添加设备描述功能

设备端添加描述desc 的json字段上报到服务器端，增加设备id可读性，可以通过设备描述关联对应设备id，比如did="02AD23968063" desc="家里的路由器myhome router,服务器端/list 打开链接时上面附上设备描述就一目了然了

Adding a description to the device.

About root login rtty failure solution

If you log in as root on some Linux systems and find that you can't enter root, you will always report the login. The main reason is that the root login terminal is not recognized. You need to add the relevant terminal tty name in /etc/securetty. Look at the login information, for example my system is ubuntu18.04, I use cat /var/log/auth.log

Sep 6 08:06:29 wateras systemd-logind[2459]: New session c22 of user root.
Sep 6 08:12:15 wateras login[30773]: pam_securetty(login:auth): access denied: tty '/dev/pts/3' is not secure !
Sep 6 08:12:18 wateras login[30773]: FAILED LOGIN (1) on '/dev/pts/3' FOR 'root', Authentication failure
Sep 6 08:12:24 wateras login[30773]: pam_securetty(login:auth): access denied: tty '/dev/pts/3' is not secure !
I only need to add pts/3 to the /etc/securetty file. This is based on the error message. In practice, just add pts/0~pts/3. This way you can use root to log in to rtty.
