Problem with non-interactive command handle

[inot]

Hello, got strange problem. Everything fine if I've connected by a ssh client, got a shell prompt, sent a message, got an answer.

But If I tried to use script for the same commands. After script I've got error here "line, readLineError := term.ReadLine()" and readLineError=EOF. Looks like script cant send command or server cant get it.

I'm absolutely sure that I done something wrong. Can you send me the right signals? )

ssh client output

[email protected]'s password:
inot $ id
ID

script output:

inot $ Wrong Command

Server Part

func main() {

	// Create a new server instance
	s := &ssh.Server{
		Addr:            "0.0.0.0:2222",
		Handler:         handleSession,
		PasswordHandler: handleAuthentication,
		IdleTimeout:     60 * time.Second,
	}

	key, err := ReadPrivateKeyFromFile("key.rsa")
	if err != nil {
		panic(err)
	}
	s.AddHostKey(key)
	log.Printf("[+]Starting SSH server on address: %v\n", s.Addr)
	log.Fatal(s.ListenAndServe())

}

func handleSession(s ssh.Session) {
	defer s.Exit(0)
	term := term.NewTerminal(s, s.User()+" $ ")
	line, readLineError := term.ReadLine()
	if readLineError != nil {
		log.Print("Error: ")
		log.Println(readLineError)
	}
	proccessIncomeMessage(line, s)
}

func proccessIncomeMessage(line string, s ssh.Session) {
	switch line {
	case "id":
		io.WriteString(s, "ID")
	default:
		io.WriteString(s, "Wrong Command")
	}
}

Client Part

	client, err := ssh.Dial("tcp", host+":"+port, config)
	if err != nil {
		log.Fatal(err)
	}
	defer client.Close()

	// start session
	sess, err := client.NewSession()
	if err != nil {
		log.Fatal(err)
	}
	defer sess.Close()

	// setup standard out and error
	// uses writer interface
	sess.Stdout = os.Stdout
	sess.Stderr = os.Stderr

	// run single command
	err = sess.Run(cmd)
	if err != nil {
		log.Fatal(err)
	}

I've changed handleSession to

func handleSession(s ssh.Session) {
	defer s.Exit(0)
	line := s.RawCommand()
	proccessIncomeMessage(line, s)
}

now everything ok.
