通过 C++ 编码的客户端和服务器在 TCP/IP 网络通信中读取、创建和操作全帧

Question

I would like to code my own client and server in C++ (which I have found plenty of tutorials on) and access to all information about the headers and all the fields in a frame that is going to be sent across a network.

I need it to be able to edit and/or manipulate information in all the header fields before sending the frame across the network. What's more, it needs to be able to receive a frame and read/manipulate all the header fields from layer 2 to up layer.

I just want to know what library in C++ I need to use or is there any information on how I can code something to accomplish this via C++ that I can be directed to?

Answer 1

If you want to construct a client/server, it's easy. But if you want to build a packet from MAC to Transport Layer, then you need to use the Linux kernel. You need to have some knowledge about how the packets are sent and received. What's more, we always use C to realise it.
