ansible telnet 不工作

我正在尝试将 telnet 命令与 ansible Expect 模块一起使用来推送初始配置，但它不起作用，我怀疑问题出在响应部分，这是我的剧本：

- hosts: wired
  gather_facts: false
  connection: local
  tasks:
  - name: telnet,login and execute command
    ignore_errors: no
    expect:
      command: telnet "{{ inventory_hostname }}" 2009
      responses:
        .*>: "enable"
        .*Password: "mainpass"
        .*#: "show runn | in hostname"
    register: telnet_output
  - name: Debug output
    debug: var=telnet_output.stdout_lines

当我尝试从终端远程登录时，我得到以下信息：

Trying 10.1.1.1...
Connected to switch.lab.local.
Escape character is '^]'.

我需要按 Enter 键，然后我会看到：

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
To log in to this device, use the following password/credentials:

enable password mainpass   
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


switch>

然后我必须输入命令启用，系统会提示输入启用密码：

switch>enable
Password: 
switch#

我无法将上面的内容翻译到我的剧本中的响应部分，当我运行它时，我看到这个：

fatal: [switch]: FAILED! => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },

                "telnet: Unable to connect to remote host: Connection refused": ""
            },
            "timeout": 30
        }
    },

    "rc": 1,

    "stdout": "Trying 10.1.1.1...\r\ntelnet: Unable to connect to remote host: Connection refused",
    "stdout_lines": [
        "Trying 10.1.1.1...",
        "telnet: Unable to connect to remote host: Connection refused"
    ]
}

由于您看到 Connection Refused 消息，我认为 Ansible 连接没有像您期望/希望的那样工作。 Ansible 构建了特殊的模块来处理网络设备，请参见此处：https://docs.ansible.com/ansible/latest/network/getting_started/network_differences.html

我认为您最好的选择是阅读这些文档以了解如何进行设置。此外，telnet 以纯文本形式通过线路传输，因此如果设备支持，您确实应该升级到 SSH 或 HTTPS API。
