Paramiko “Unknown Server”

Question

I\'m trying to get started with the Paramiko library, but the library is throwing an exception as soon as I try to connect with the following simple program:

Answer 1

The exception was raised because you are missing a host key, the rather cryptic "Unknown server" is the clue - since the exception was raised from missing_host_key

Try this instead:

import paramiko

paramiko.util.log_to_file('ssh.log') # sets up logging

client = paramiko.SSHClient()
client.load_system_host_keys()
client.connect('127.0.0.1', username=username, password=password)
stdin, stdout, stderr = client.exec_command('ls -l')
