// much help received from https://github.com/mindreframer/golang-stuff/blame/master/github.com/mitchellh/packer/communicator/ssh/password.go

package main

import (
	"fmt"
	"github.com/pkg/sftp"
	"golang.org/x/crypto/ssh"
)

func main() {

	c := &ssh.ClientConfig{
		User: "[username]", // replace this
		Auth: []ssh.AuthMethod{
			ssh.KeyboardInteractive(func(user, instruction string, questions []string, echos []bool) ([]string, error) {
				// Just send the password back for all questions
				answers := make([]string, len(questions))
				for i, _ := range answers {
					answers[i] = "[password]" // replace this
				}

				return answers, nil
			}),
		},
	}

	connection, err := ssh.Dial("tcp", "[host]:[port]", c) // replace this
	if err != nil {
		fmt.Println(err)
		return
	}

	server, err := sftp.NewClient(connection)
	if err != nil {
		fmt.Println(err)
		return
	}

	dir, err := server.ReadDir(".")
	if err != nil {
		fmt.Println(err)
		return
	}

	for _, fi := range dir {
		fmt.Println(fi.Name())
	}
}
