ssh: must specify HostKeyCallback

[songtianyi]

go version

go version go1.8 darwin/amd64

ssh version

OpenSSH_7.3p1, LibreSSL 2.4.1

code went wrong

package main

import (
	"fmt"
	"golang.org/x/crypto/ssh"
	"log"

	"github.com/Juniper/go-netconf/netconf"
)

func main() {
	sshConfig := &ssh.ClientConfig{
		Config: ssh.Config{
			Ciphers: []string{"aes128-cbc", "hmac-sha1"},
		},
		User: "root",
		Auth: []ssh.AuthMethod{ssh.Password("xxxx")},
	}

	s, err := netconf.DialSSH("172.16.240.189", sshConfig)

	if err != nil {
		log.Fatal(err)
	}

	defer s.Close()

	fmt.Println(s.ServerCapabilities)
	fmt.Println(s.SessionID)

	reply, err := s.Exec(netconf.MethodGetConfig("running"))
	if err != nil {
		panic(err)
	}
	fmt.Printf("Reply: %+v", reply)
}

it still went wrong even if i added the HostKeyCallback

package main

import (
	"fmt"
	"golang.org/x/crypto/ssh"
	"log"
	"net"

	"github.com/Juniper/go-netconf/netconf"
)

func main() {
	sshConfig := &ssh.ClientConfig{
		Config: ssh.Config{
			Ciphers: []string{"aes128-cbc", "hmac-sha1"},
		},
		User: "root",
		Auth: []ssh.AuthMethod{ssh.Password("xxx")},
		HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error {
			return nil
		},
	}

	s, err := netconf.DialSSH("172.16.240.189", sshConfig)

	if err != nil {
		log.Fatal(err)
	}

	defer s.Close()

	fmt.Println(s.ServerCapabilities)
	fmt.Println(s.SessionID)

	reply, err := s.Exec(netconf.MethodGetConfig("running"))
	if err != nil {
		panic(err)
	}
	fmt.Printf("Reply: %+v", reply)
}
