Why does paramiko hang in python3?

Question

Python

In some cases (in which ones - not installed, difficult to reproduce)) hangs in this line:
ssh.connect(target, port = sshpo

def connect(target, sshport, user, password):
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        try:
            ssh.connect(target, port = sshport, username = user, password = password, timeout=5, banner_timeout = 5, auth_timeout=5)
            resultCode = 1
        except paramiko.AuthenticationException:
            resultCode = 0
        except socket.error:
            resultCode = 2

Answer 1
