问题描述

有没有办法使用 Paramiko 和 Python 来获取您尝试连接的 SSH 服务器的横幅?

Is there a way using Paramiko and Python to get the banner of the SSH server you attempt to connect to?

我正在为许多机器处理一个超安全的服务器设置过程，密码是通过预定义的密钥生成的，该密钥与 SSH 横幅一起打印出来.我可以访问提供密码的实用程序，但我需要横幅中的文本才能实际生成初始密码.

I am dealing with an ultra secure server setup process for many machines and the passwords are generated via a predefined cipher key which get's printed out at with the SSH banner. I have access to the utility that will give me the password, but I need the text in the banner to actually generate the initial password.

看起来这不是一个功能.好在我要求它，非常棒的开发人员把它放进去了......

Looks like this wasn't a feature. Good thing I requested it and the totally awesome developers put it in...

# !/usr/bin/python

import paramiko


def grab_banner(ip_address, port):
    client = paramiko.SSHClient()
    client.load_system_host_keys()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    try:
        client.connect(ip_address, port=port, username='username', password='bad-password-on-purpose')
    except:
        return client._transport.get_banner()


if __name__ == '__main__':
    print grab_banner('192.168.1.26', 22)
