Paramiko: password + sms-passcode autentification

Question

I need to connect to a server using ssh from Python. Usually I use Paramiko, but this server requires a passcode that is sent on SMS after the password is entered:

C:\>ssh user@hostname.com
AD Password: <password>
Enter PASSCODE: <sms passcode>

Is it possible via Paramiko / Python

Answer 1

I do not know if this is the right way to do it, but it seems to work in my case:

def interactive_auth_handler(title, instructions, prompt_list):
    if prompt_list:
        if prompt_list[0][0]=="AD Password: ":
            return [password]
        return [getpass.getpass(prompt_list[0][0])]
    return []


client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
    client.connect(host, port, username=username, password=password, pkey=None)
except paramiko.ssh_exception.SSHException as e:
    transport = client.get_transport()
    transport.auth_interactive(username, interactive_auth_handler)
