windows客户端和linux服务器之间的通信? [英] communication between windows client and linux server?
问题描述
我在 c 中执行客户端(windows)和服务器(linux RT)之间的通信.我为 Windows 操作系统(一台笔记本电脑)编写了客户端代码，为 linux 操作系统(另一台笔记本电脑)编写了服务器代码.我通过以太网电缆连接两台笔记本电脑，并将它们配置在同一子网上.
I am performing communication between client(windows) and server(linux RT) in c. I have written a client code for windows operating system (one laptop) and server code for linux operating system (another laptop). I am connecting the both laptop via ethernet cable and configured them on the same subnet.

我的问题:
- 是否可以进行这样的交流??
- 我要为此采取具体措施吗??
请给出关于此的想法?
推荐答案
您可以直接连接两个系统(通过以太网电缆)，但通常您必须为此使用特殊电缆:它被称为交叉电缆".否则无法连接.
You can connect two systems directly (via ethernet cable), but typically you must use a special cable for that: it is called a "crossover cable". Otherwise no connection is possible.
较新的网络控制器实现了对此类设置的检测，因此可能可以为此设置使用标准电缆，但这取决于两个系统中内置的网络控制器.您将不得不尝试或查阅文档.
Newer network controllers implement a detection for this kind of setup, so it might be possible to use a standard cable for this setup, but this depends on the network controllers build into the two systems. You will have to try or consult the documentation.
也可能是您必须在 MS-Windows 端(在网络适配器配置内)选择一些特殊配置才能使其工作.我几次遇到标准设置的通信问题.你可以向谷歌咨询这些设置.
Also it migh be that you have to select some special configuration on the MS-Windows side (inside the network adapter configuration) for this to work. I experienced communication problems with the standard setup a few times. You can consult google for those settings.
