	func (node *Node) Connect(username string, auth ssh.AuthMethod) error {
	//var hostKey ssh.PublicKey
	// An SSH client is represented with a ClientConn.
	//
	// To authenticate with the remote server you must pass at least one
	// implementation of AuthMethod via the Auth field in ClientConfig,
	// and provide a HostKeyCallback.
	config := &ssh.ClientConfig{
	User: username,
	Auth: []ssh.AuthMethod{
	auth,
	},
	//HostKeyCallback: ssh.FixedHostKey(hostKey),
	HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error {

should be

func (node *Node) Connect(username string, pwd string) error { 
 	
 	config := &ssh.ClientConfig{ 
 		User: username, 
 		Auth: []ssh.AuthMethod{
                    ssh.Password(pwd),
                    ssh.KeyboardInteractive(func(name, instruction string, questions []string, echos []bool) ([]string, error){
                        answers := make([]string, len(questions))
                        for i := range answers {
                            answers[i] = pwd
                        }
                        return answers, nil
                    }),
                },
 		//HostKeyCallback: ssh.FixedHostKey(hostKey), 
 		HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error { 
 			return nil 
 		}, 
 	} 

or

func (node *Node) Connect(username string, auth []ssh.AuthMethod) error { 
 	
 	config := &ssh.ClientConfig{ 
 		User: username, 
 		Auth: auth,
 		//HostKeyCallback: ssh.FixedHostKey(hostKey), 
 		HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error { 
 			return nil 
 		}, 
 	}
