如何以编程方式检查远程主机的操作系统? [英] How to check programmatically the OS of remote host?

问题描述

我需要检查远程主机是 Windows 还是 Unix/Linux.我不能假设它配置了网络服务器.我所能做的就是尝试连接到多个 TCP 或 UDP 服务.

I need to check if remote host is Windows or Unix/Linux. I can't assume that it has web server configured. All I can do is to try to connect to several TCP or UDP services.

哪些 TCP 服务(TCP 端口号)通常会在 Windows 上打开，而不会在 Unix/Linux 上打开，反之亦然?

Which TCP services (TCP port numbers) usually will be opened on Windows and not on Unix/Linux and vise versa?

另一种方法是尝试通过 ssh 连接到它，如果失败，则假定它是 Windows 主机.问题是，我需要这个来选择远程访问方法 ssh 或 Windows 友好的东西，比如 psexec.

The other way is to try to ssh to it, and if it fails assume that it Windows host. The problem is, that I need this in order to choose the remote access method ssh or something Windows friendly like psexec.

推荐答案

You can read the output of nmap to detect which OS a remote host is running. It has a whole module dedicated to this. Here is a guide to using it.
