How to build

mkdir mysocks
cd mysocks
git clone https://github.com/tuanwork98/socks5.git

# Init module
go mod init mysocks

# Create main.go
cat << EOF > main.go
package main
import (
        "mysocks/socks5"
)
func main() {
    // Create a SOCKS5 server
    conf := &socks5.Config{}
    server, err := socks5.New(conf)
    if err != nil {
        panic(err)
    }

    // Create SOCKS5 proxy on localhost port 8000
    if err := server.ListenAndServe("tcp", "127.0.0.1:8001"); err != nil {
        panic(err)
    }
}

# Install requitments module and Build 
go mod tidy
go build -o socks-server main.go

go-socks5

Provides the socks5 package that implements a SOCKS5 server. SOCKS (Secure Sockets) is used to route traffic between a client and server through an intermediate proxy layer. This can be used to bypass firewalls or NATs.

Feature

The package has the following features:

• "No Auth" mode
• User/Password authentication
• Support for the CONNECT command
• Rules to do granular filtering of commands
• Custom DNS resolution
• Unit tests

TODO

The package still needs the following:

• Support for the BIND command
• Support for the ASSOCIATE command

Example

Below is a simple example of usage

// Create a SOCKS5 server
conf := &socks5.Config{}
server, err := socks5.New(conf)
if err != nil {
  panic(err)
}

// Create SOCKS5 proxy on localhost port 8000
if err := server.ListenAndServe("tcp", "127.0.0.1:8000"); err != nil {
  panic(err)
}
