If I haven't logged on for a few days, I always feel that I have less things (because I caught a thief). Today I want to talk about the small test recently. It seems that I can change it on a large project in the future. 1 broadcast: (IPv4 and no v6

The server is very similar to the client program. The client program is learned in the previous section. This section describes how to use socket to establish TCP and UDP servers. 1. TCP connection establishment method Generally, two steps are

For raw sockets, only root privileges can be created.There are three main functions of raw sockets:1. The raw socket is used to receive the ICMP,IGMP protocol package sent to the native, or to send the protocol packets.2. Receive IP packets that are
