Clash
A rule-based tunnel in Go.
## Features
- HTTP/HTTPS and SOCKS protocol
- Surge like configuration
- GeoIP rule support
- Support Vmess/Shadowsocks/Socks5
- Support for Netfilter TCP redirect
## Install
You can build from source:
```sh
go get -u -v github.com/Dreamacro/clash
```
Pre-built binaries are available: [release](https://github.com/Dreamacro/clash/releases)
Requires Go >= 1.12.
Checkout Clash version:
```sh
clash -v
```
## Daemon
Unfortunately, there is no native elegant way to implement golang's daemon.
So we can use third-party daemon tools like pm2, supervisor, and so on.
In the case of [pm2](https://github.com/Unitech/pm2), we can start the daemon this way:
```sh
pm2 start clash
```
If you have Docker installed, you can run clash directly using `docker-compose`.

## Config
The default configuration directory is `$HOME/.config/clash`
The name of the configuration file is `config.yml`
If you want to use another directory, you can use `-d` to control the configuration directory
For example, you can use the current directory as the configuration directory
```sh
clash -d .
```
Below is a simple demo configuration file:
```yml
# port of HTTP
port: 7890
# port of SOCKS5
socks-port: 7891
# redir port for Linux and macOS
# redir-port: 7892
allow-lan: false
# Rule / Global/ Direct (default is Rule)
mode: Rule
# set log level to stdout (default is info)
# info / warning / error / debug / silent
log-level: info
# A RESTful API for clash
external-controller: 127.0.0.1:9090
# you can put the static web resource (such as clash-dashboard) to a directory, and clash would serve in `${API}/ui`
# input is a relative path to the configuration directory or an absolute path
# external-ui: folder
# Secret for RESTful API (Optional)
# secret: ""
# dns:
# enable: true # set true to enable dns (default is false)
# ipv6: false # default is false
# listen: 0.0.0.0:53
# enhanced-mode: redir-host
# nameserver:
# - 114.114.114.114
