Ansible ping 不起作用

我在 Ubuntu 机器（18.04.2）中的 VM Workstation 15 Pro 中使用 Ansible 2.7.10，并尝试在 GNS3 中连接思科路由器（3700 软件（C3725-ADVIPSERVICESK9-M），版本 12.4(23)）。

原始 ssh 正在从 Ubuntu 终端运行，但在尝试通过 ansible ping 模块进行 ping 时出现以下错误。

请指教。

模块ping​在 ansible 中，实际上并不像你从 shell 手动执行的那样 ping 主机。来自上面的文档链接：

这不是 ICMP ping，这只是一个需要远程节点上的 Python 的简单测试模块。

由于您的目标是网络设备，因此您会收到错误，因为 ansible 试图在使用 python 执行某些文件之前将其传输到设备，就像在“普通”主机上一样。 在您的例子中，设备文件系统在预期路径上是只读的或不可写的（这并不奇怪），ansible 会触发错误。

看看ios_ping和net_ping可能满足您需求的模块。
