ttyd is a simple command-line tool for sharing terminal over the web, inspired by [GoTTY][1].
|
|
|
|
|
|
|
|
# Features
|
|
|
|
- Built on top of [Libwebsockets][2] with C for speed
|
|
- Fully-featured terminal based on [Xterm.js][3] with CJK (*Chinese, Japanese, Korean*) and IME support
|
|
- SSL support based on [OpenSSL][4]
|
|
- Run any custom command with options
|
|
- Basic authentication support and many other custom options
|
|
- Cross platform: macOS, Linux, FreeBSD, [OpenWrt][5]/[LEDE][6]
|
|
|
|
# Installation
|
|
|
|
## Install on macOS
|
|
|
|
Install with [homebrew][7]:
|
|
|
|
```bash
|
|
brew install ttyd
|
|
```
|
|
|
|
## Install on Linux
|
|
|
|
Ubuntu 16.04 as example:
|
|
|
|
```bash
|
|
sudo apt-get install cmake g++ pkg-config git vim-common libwebsockets-dev libjson-c-dev libssl-dev
|
|
git clone https://github.com/tsl0922/ttyd.git
|
|
cd ttyd && mkdir build && cd build
|
|
cmake ..
|
|
make && make install
|
|
```
|
|
|
|
> **NOTE:** You may need to compile libwebsockets from source for ubuntu versions old than 16.04, since they have outdated `libwebsockets-dev` package ([Issue #6][9]).
|
|
|
|
## Install on OpenWrt/LEDE
|
|
|
|
```bash
|
|
opkg install ttyd
|
|
```
|
|
|
|
> **NOTE:** This may only works for [LEDE][6] snapshots currently, if the install command fails, [compile it yourself](openwrt).

## Example Usage
|
|
|
|
ttyd starts web server at port `7681` by default, you can use the `-p` option to change it, the `command` will be started with `arguments` as options. For example, run:
|
|
|
|
```bash
|
|
ttyd -p 8080 bash -x
|
|
```
|
|
Then open <http://localhost:8080> with a broswer, you will get a bash shell with debug mode enabled.
|
|
|
|
**More Examples:**
|
|
|
|
- If you want to login with your system accounts on the web broswer, run `ttyd login`.
|
|
- You can even run a none shell command like vim, try: `ttyd vim`, the web broswer will show you a vim editor.
|
|
- Sharing single process with multiple clients: `ttyd tmux new -A -s ttyd vim`, run `tmux new -A -s ttyd` to connect to the tmux session from terminal.
|
|
|
|
## Docker and ttyd
|
|
|
|
Docker containers are jailed environments which are more secure, this is useful for protecting the host system, you may use ttyd with docker like this:
|
|
|
|
- Sharing single docker container with multiple clients: `docker run -it --rm -p 7681:7681 tsl0922/ttyd`.
|
|
- Creating new docker container for each client: `ttyd docker run -it --rm ubuntu`.
