Вообщем использую python библиотеку: asyncssh для выполнения команд по ssh. Вот код:

@asyncio.coroutine
def run_client():
    conn, client = yield from asyncssh.connection("178.79.132.133", username="root", password="1234")
    with conn:
        stdin, stdout, stderr = yield from conn.open_session('echo "Hello!"')
        output = yield from stdout.read()
        print(output, end='')

        status = stdout.channel.get_exit_status()
        if status:
            print('Program exited with status %d' % status, file=sys.stderr)
        else:
            print('Program exited successfully')

if __name__ == "__main__":
    asyncio.get_event_loop().run_until_complete(run_client())

Но к сожалению ничего не происходит и в консоль ничего не выводиться...

В консоли без проблем могу зайти: ssh [email protected] Потом ввожу пароль, все хорошо, а тут не работает, где ошибка? При помощи paramiko тоже все хорошо работало.

Вообщем дальше больше. Стал выеснять. К серверу, который на Ubuntu присоединяется, а вот на OpenSUSE почему-то не получается.

Стал смотреть логи соединения:

Скажите, что не так? Что нужно поправить в настройках сервера ssh?

Вообщем выяснил. Оказывается у ssh есть несколько типов авторизации: publickey,keyboard-interactive, password. Как я понял, когда мы используем консольный клиент, то используется (не рассматриваю вариант с ключами) keyboard-interactive, видимо paramiko как-то умеет эмулировать данный тип, а вот asyncssh нет, ну или я не разобрался как. Решение оказалось простым:

  1. Через ключи
  2. На сервере ssh поставить: PasswordAuthentication yes
2
  • Зачем разрешать пароли, если Вы ключи используете?

  • Пока тест, то и с паролями покатит. 4 ноя 2015 в 16:51
