glider
glider is a forward proxy with multiple protocols support, and also a dns forwarding server with ipset management features(like dnsmasq).
we can set up local listeners as proxy servers, and forward requests to internet via forwarders.
|Forwarder ----------------->|
Listener --> | | Internet
|Forwarder --> Forwarder->...|
Features
Listen(local proxy server):
- Socks5 proxy
- Http proxy
- SS proxy
- Linux transparent proxy(iptables redirect)
- TCP tunnel
- DNS Tunnel(udp2tcp)
Forward(upstream proxy server):
- Socks5 proxy
- Http proxy
- SS proxy
DNS Forwarding Server(udp2tcp)
- Listen on UDP and forward dns requests to remote dns server in TCP via forwarders
- Specify different upstream dns server based on destinations(in rule file)
- Tunnel mode: forward to a fixed upstream dns server
- Add resolved IPs to proxy rules
- Add resolved IPs to ipset
Ipset Management
- Add ip/cidrs from rule files on startup
- Add resolved ips for domains from rule files by dns forwarding server
General:
- Http and socks5 on the same port
- Forward chain
- HA or RR strategy for multiple forwarders
- Periodical proxy checking
- Rule proxy based on destinations: Config Examples
TODO:
- UDP Tunnel
- Linux tproxy support & UDP Relay
- TUN/TAP device support
- Code refactoring: support proxy registering so it can be pluggable
- Conditional compilation so we can abandon needless proxy type and get a smaller binary size
- IPv6 support
- SSH tunnel support
Install
Binary:
Go Get (requires Go 1.9 or newer):
go get -u github.com/nadoo/glider
ArchLinux:
sudo pacman -S glider
Run
command line:
glider -listen :8443 -verbose
config file:
glider -config CONFIGPATH
command line with config file:
glider -config CONFIGPATH -listen :8080 -verbose
Usage
glider v0.3.1 usage:
-checkduration int
proxy check duration(seconds) (default 30)
-checkwebsite string
proxy check HTTP(NOT HTTPS) website address, format: HOST[:PORT], default port: 80 (default "www.apple.com")
-config string
config file path
-forward value
forward url, format: SCHEMA://[USER|METHOD:PASSWORD@][HOST]:PORT[,SCHEMA://[USER|METHOD:PASSWORD@][HOST]:PORT]
-listen value
listen url, format: SCHEMA://[USER|METHOD:PASSWORD@][HOST]:PORT
-rulefile value
rule file path
-strategy string
forward strategy, default: rr (default "rr")
-verbose
verbose mode
Available Schemas:
mixed: serve as a http/socks5 proxy on the same port. (default)
ss: ss proxy
socks5: socks5 proxy
http: http proxy
redir: redirect proxy. (used on linux as a transparent proxy with iptables redirect rules)
tcptun: a simple tcp tunnel
dnstun: listen on udp port and forward all dns requests to remote dns server via forwarders(tcp)
Available schemas for different modes:
listen: mixed ss socks5 http redir tcptun dnstun
forward: ss socks5 http
Available methods for ss:
AEAD_AES_128_GCM AEAD_AES_192_GCM AEAD_AES_256_GCM AEAD_CHACHA20_POLY1305 AES-128-CFB AES-128-CTR AES-192-CFB AES-192-CTR AES-256-CFB AES-256-CTR CHACHA20-IETF XCHACHA20
NOTE: chacha20-ietf-poly1305 = AEAD_CHACHA20_POLY1305
Available forward strategies:
rr: Round Robin mode
ha: High Availability mode
Config file format(see `glider.conf.example` as an example):
# COMMENT LINE
KEY=VALUE
KEY=VALUE
# KEY equals to command line flag name: listen forward strategy...
Examples:
glider -config glider.conf
-run glider with specified config file.
glider -config glider.conf -rulefile office.rule -rulefile home.rule
-run glider with specified global config file and rule config files.
