Мне нужно выполнить команду на удаленном сервере, используя paramiko Channel.
Код:
def handler(title, instructions, fields):
if len(fields) > 1:
raise sftp.SSHException("Expecting one field only.")
return [password]
def create_sftp_client():
#from transport object
sftp.util.log_to_file("paramiko", level="DEBUG")
transport = sftp.Transport(('myhost', 2222),
default_max_packet_size=10000, default_window_size=10000)
transport.connect(username='myuser', password='mypassword')
transport.auth_interactive(username, handler)
channel = transport.open_channel("session")
channel.invoke_shell()
channel.send('ls\n')
return channel
StackTrace:

Я попробовал решение ниже, но не помогло:

Есть мысли, пожалуйста?
