PowerShell 询问远程系统

Question

我编写了一个查询本地系统的函数。只是以有用的格式收集我能得到的任何信息。所以我想知道可以用这种方式询问其他系统的功能。 function sys-remote <$ip-or-hostname> 这样它就可以尝试 return 尽可能多地了解有关该系统的信息。这真的只是一个想法，我想有几点会有用：

• 有了 IP 地址，我们如何才能以最类似于 PowerShell 的方式解析主机名？

• 是否提供了IP地址的主机名，我们能不能解析尽可能多的信息。即 MAC 地址、主机名、IP（如果我们可以看到这些，可能还有其他 IP 地址）？

• 我们能否恢复该系统上的共享驱动器，以便查看可能要连接的共享列表。

• 系统信息如何，总是需要 WinRM，还是 WMI 或 CIM 可以满足下面的大部分内容？

• 也许 return 如果可能的话，还有一个以逗号分隔的列表，列出该远程系统上打开的任何端口？

• 如果远程系统是 Linux 怎么办？从我们的 Windows 系统远程查询的 Linux 系统中，我们可以合理地获得多少上述内容（我猜 WinRM 和 WMI 已经过时了，但也许 CIM 仍然可行？）？

一般来说，return 从诊断的角度来看，这样的信息转储会非常有用，因为它会提供大量关于系统工作的信息。像上面的任何东西（或者实际上任何其他我在这里没有想到的有用的东西来检查）将不胜感激。
