levels of DOS, CC and SYN attacks.In addition, if you have a large number of connections, we can optimize the TCP port range to further improve the concurrency of the server. Still go to the above parameter file, add the following configuration:net.ipv4.tcp_keepalive_time = 10000 = 65000= 8192= 5000#这几个参数, it is recommended to only open on servers with very large traffic, which can have significant effects.
