Host key inspection bypass using the paramiko SSH library.

The paramiko library will automatically reject unknown host keys on connection. This can be disabled by calling the set_missing_host_key_policy() method on a client instance.

This practice is discouraged, as an attacker could be using DNS injection, or another technique, such as IP spoofing to trick the client into connecting to a different server.

Example

import paramiko

client = paramiko.client.SSHClient()
client.set_missing_host_key_policy(paramiko.client.AutoAddPolicy)
