how to ssh to user@host in python?

Question

import paramiko

host = "172.21.14.48"
port = 22
username = "user"
password = "xxx*9841"
command = "ls"
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(host, port, username, password )
stdin, stdout, stderr = ssh.exec_command(command)
lines = stdout.readlines()
print(lines)

This code works SSH successful. But I need to ssh to [email protected] with same username and password.

Using username "cp".
Keyboard-interactive authentication prompts from server:
Actual Username:
Actual Password:

I tried below code but getting error.

host = "[email protected]"

Error message as:

File "C:\Program Files\Python38\lib\socket.py", line 918, in getaddrinfo
for res in _socket.getaddrinfo(host, port, family, type, proto, flags): socket.gaierror: [Errno 11003] getaddrinfo failed

However with PuTTY I can ssh to [email protected]. Any suggestion..?

Answer 1

The cp in the ssh [email protected] is a username, so it goes to the username argument of SSHClient.connect:

username = "cp"
# ...
ssh = paramiko.SSHClient()
ssh.connect(host, port, username, password)

Your server prompts for another set of credentials using keyboard interactive authentication.
For that see: Password authentication in Python Paramiko fails, but same credentials work in SSH/SFTP client
You have to adjust the code to answer both the second username and password prompts. The fields parameter of the handler will have two entries and the handler has to return a two answers in its result.
