通过ifconfig来确认

package main

import (

"log"

"os"

"os/exec"

"syscall"

)

func main() {

cmd := exec.Command("/bin/bash")

cmd.Stdout = os.Stdout

cmd.Stderr = os.Stderr

cmd.Stdin = os.Stdin

cmd.SysProcAttr = &syscall.SysProcAttr{}

cmd.SysProcAttr.Cloneflags = syscall.CLONE_NEWNET

if err := cmd.Run(); err != nil {

log.Fatal(err)

}

}
