Minimal SOCKS5 proxy server in Go

simplesocks5proxyserver.go

// For use in the tutorial at https://blog.simos.info/a-network-isolated-container-in-lxd/
// Source: https://github.com/armon/go-socks5
//
// To compile, run once:    go get github.com/armon/go-socks5
//             then run:    go run simplesocks5proxyserver.go       
//

package main

import (
    "fmt"
    "log"
    "os"

    "github.com/armon/go-socks5"
)

func main() {
    // Create a SOCKS5 server
    config := &socks5.Config{
        Logger:      log.New(os.Stdout, "SOCKS5Server", log.LstdFlags),
    }
    server, err := socks5.New(config)
    if err != nil {
        panic(err)
    }

    fmt.Print("Listening on 127.0.0.1:10080...\n");
    fmt.Print("Press Ctrl+C to interrupt: ");

    // Create SOCKS5 proxy on localhost port 1080
    if err := server.ListenAndServe("tcp", "127.0.0.1:10080"); err != nil {
        panic(err)
    }
}

@simos, what should I do to resolve this compilation error? The Go compiler apparently misinterprets the go-socks5 module import as a local import.

@derekmahar, indeed, you get this error when you build this Go code.

Run first,

go get github.com/armon/go-socks5

and then you should be able to go run successfully.

Thank you! That fixed the problem.

Note that go get github.com/armon/go-socks5 downloaded the package into ~/go/pkg:
