PowerShell询问远程系统

Question

我编写了一个查询本地系统的函数。只要收集我能以有用格式获得的所有信息即可。所以我想知道一个功能是否可以这种方式询问其他系统。 function sys-remote <$ip-or-hostname>这样，它就可以尝试并尽可能多地返回有关该系统的信息。这实际上只是一个想法，我想有很多要点：

•使用IP地址，我们如何以最类似于PowerShell的方式解析主机名？

•是否提供IP地址的主机名，我们能否解析尽可能多的信息。即MAC地址，主机名，IP（以及可能对我们可见的其他IP地址）？

•我们可以在该系统上恢复共享驱动器吗，所以可以看到要连接的共享列表。

•关于系统信息，总是需要WinRM，还是WMI或CIM可以满足以下大多数情况？

•可能的话，还可能返回该远程系统上打开的任何端口的逗号分隔列表？

•如果远程系统是Linux，该怎么办。从我们可以从Windows系统远程查询的Linux系统中，可以合理地从上述系统中获得多少（我猜WinRM和WMI已经淘汰，但也许CIM仍然可行？）？

通常，从诊断的角度返回这样的信息转储非常有用，因为它将提供有关要使用的系统的大量信息。像上面的任何事情（或者实际上是我在这里没有想到的其他有用的检查内容）都将不胜感激。

没有理由从头开始做这种事情。有许多用于执行操作的现有脚本。通过Microsoft powershellgallery.com。
