Meta Kernel
Another Clash Kernel.
## Features
- Local HTTP/HTTPS/SOCKS server with authentication support
- VMess, Shadowsocks, Trojan, Snell protocol support for remote connections
- Built-in DNS server that aims to minimize DNS pollution attack impact, supports DoH/DoT upstream and fake IP.
- Rules based off domains, GEOIP, IPCIDR or Process to forward packets to different nodes
- Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node based off latency
- Remote providers, allowing users to get node lists remotely instead of hardcoding in config
- Netfilter TCP redirecting. Deploy Clash on your Internet gateway with `iptables`.
- Comprehensive HTTP RESTful API controller
## Getting Started
Documentations are now moved to [GitHub Wiki](https://github.com/Dreamacro/clash/wiki).
## Advanced usage for this branch
### DNS configuration
Support `geosite` with `fallback-filter`.
Restore `Redir remote resolution`.
Support resolve ip with a `Proxy Tunnel`.
```yaml
proxy-groups:
- name: DNS
type: url-test
use:
- HK
url: http://cp.cloudflare.com
interval: 180
lazy: true
```
```yaml
dns:
enable: true
use-hosts: true
ipv6: false
enhanced-mode: redir-host
fake-ip-range: 198.18.0.1/16
listen: 127.0.0.1:6868
default-nameserver:
- 119.29.29.29
- 114.114.114.114
nameserver:
- https://doh.pub/dns-query
- tls://223.5.5.5:853
fallback:
- 'https://1.0.0.1/dns-query#DNS' # append the proxy adapter name or group name to the end of DNS URL with '#' prefix.
- 'tls://8.8.4.4:853#DNS'
fallback-filter:
geoip: false
geosite:
- gfw # `geosite` filter only use fallback server to resolve ip, prevent DNS leaks to unsafe DNS providers.
domain:
- +.example.com
ipcidr:
- 0.0.0.0/32
```
### TUN configuration
Supports macOS, Linux and Windows.
Built-in [Wintun](https://www.wintun.net) driver.
```yaml
# Enable the TUN listener
tun:
enable: true
stack: gvisor # only gvisor
dns-hijack:
- 0.0.0.0:53 # additional dns server listen on TUN
auto-route: true # auto set global route
```
### Rules configuration
- Support rule `GEOSITE`.
- Support rule-providers `RULE-SET`.
- Support `multiport` condition for rule `SRC-PORT` and `DST-PORT`.
- Support `network` condition for all rules.
- Support source IPCIDR condition for all rules, just append to the end.
- The `GEOSITE` databases via https://github.com/Loyalsoldier/v2ray-rules-dat.
```yaml
rules:
# network(tcp/udp) condition for all rules
- DOMAIN-SUFFIX,bilibili.com,DIRECT,tcp
- DOMAIN-SUFFIX,bilibili.com,REJECT,udp
# multiport condition for rules SRC-PORT and DST-PORT
- DST-PORT,123/136/137-139,DIRECT,udp
# rule GEOSITE
- GEOSITE,category-ads-all,REJECT
- GEOSITE,icloud@cn,DIRECT
- GEOSITE,apple@cn,DIRECT
- GEOSITE,apple-cn,DIRECT
- GEOSITE,microsoft@cn,DIRECT
- GEOSITE,facebook,PROXY
- GEOSITE,youtube,PROXY
- GEOSITE,geolocation-cn,DIRECT
- GEOSITE,geolocation-!cn,PROXY
# source IPCIDR condition for all rules in gateway proxy
#- GEOSITE,geolocation-!cn,REJECT,192.168.1.88/32,192.168.1.99/32
- GEOIP,telegram,PROXY,no-resolve
- GEOIP,private,DIRECT,no-resolve
- GEOIP,cn,DIRECT
- MATCH,PROXY
```
### Proxies configuration
Active health detection `urltest / fallback` (based on tcp handshake, multiple failures within a limited time will actively trigger health detection to use the node)
Support `Policy Group Filter`
```yaml
proxy-groups:
- name: 🚀 HK Group
type: select
use:
- ALL
filter: 'HK'
- name: 🚀 US Group
type: select
use:
- ALL
filter: 'US'
proxy-providers:
ALL:
type: http
url: "xxxxx"
interval: 3600
path: "xxxxx"
health-check:
enable: true
interval: 600
url: http://www.gstatic.com/generate_204
```
Support outbound transport protocol `VLESS`.
The XTLS support (TCP/UDP) transport by the XRAY-CORE.
```yaml
proxies:
- name: "vless"
type: vless
server: server
port: 443
uuid: uuid
servername: example.com # AKA SNI
# flow: xtls-rprx-direct # xtls-rprx-origin # enable XTLS
# skip-cert-verify: true
- name: "vless-ws"
type: vless
server: server
port: 443
uuid: uuid
tls: true
udp: true
network: ws
servername: example.com # priority over wss host
# skip-cert-verify: true
ws-opts:
path: /path
headers: { Host: example.com, Edge: "12a00c4.fm.huawei.com:82897" }
- name: "vless-grpc"
type: vless
server: server
port: 443
uuid: uuid
tls: true
udp: true
network: grpc
servername: example.com # priority over wss host
# skip-cert-verify: true
grpc-opts:
grpc-service-name: grpcname
```
### IPTABLES auto-configuration
Only work on Linux OS who support `iptables`, Clash will auto-configuration iptables for tproxy listener when `tproxy-port` value isn't zero.
If `TPROXY` is enabled, the `TUN` must be disabled.
```yaml
# Enable the TPROXY listener
tproxy-port: 9898
# Disable the TUN listener
tun:
enable: false
```
Create user given name `meta`.
Run Meta Kernel by user `meta` as a daemon.
Create the systemd configuration file at /etc/systemd/system/Clash-Meta.service:
```
[Unit]
Description=Clash-Meta Daemon, Another Clash Kernel.
After=network.target
[Service]
Type=simple
User=meta
Group=meta
CapabilityBoundingSet=cap_net_admin
AmbientCapabilities=cap_net_admin
Restart=always
ExecStart=/usr/local/bin/Clash.Meta -d /etc/Clash.Meta
[Install]
WantedBy=multi-user.target
```
Launch clashd on system startup with:
```shell
$ systemctl enable Clash-Meta
```
Launch clashd immediately with:
```shell
$ systemctl start Clash-Meta
```
### Display Process name
Clash add field `Process` to `Metadata` and prepare to get process name for Restful API `GET /connections`.
To display process name in GUI please use [Dashboard For Meta](https://github.com/Clash-Mini/Dashboard).
