Original Library was imported from http://github.com/oov/socks5
I just modified and build for personal use.
this code support configuration loading.
- IP mask must be CIDR format like "1.2.3.0/24". If you want allow all client, use CIDR as "0.0.0.0/0"
- If ID/PW is supplied, use that. or IP restrictions
-
HTTPS(SNI) Censorship in korea avoid function.
- you can check the code at "socks5/server.go"
- Tested 2019-02-19 (SK Broadband, Korea)
-
IPv6 Support
- Some ISP only support IPv6 connection environment (Ex: Mobile phone tethering). and this proxy can support that.
- tested OK. (2021-03-13 / SK telecomm, iPhone + Macbook Tethering, Korea)
-
Can be run as Cascade/Upstream Proxy.
- You can setup with Adguard or some program. and works well :)
- if you want to use with windows, use released binary.
- if you want to use with linux(x86_64), just execute these command in console.
wget https://github.com/ziozzang/socks5-proxy/releases/download/1.0/socks5-proxy && chmod +x socks5-proxy
wget https://github.com/ziozzang/socks5-proxy/releases/download/1.0/socks5-proxy.config.template
or you can run with docker. :)
docker build -t socks5proxy .
docker run --rm -it -v `pwd`/socks5-proxy.config:/app/socks5-proxy.config --net=host socks5proxy
- don't forget to edit configuration.
Package socks5 implements a "SOCKS Protocol Version 5" server.
This server supports a subset of RFC 1928:
- auth methods: "NO AUTHENTICATION REQUIRED", "USERNAME/PASSWORD"
- commands: "CONNECT"
- address types: "IP V4 address", "DOMAINNAME", "IP V6 address" (but tested "DOMAINNAME" only)
