That is to say, a total of false syn messages will occupy the TCP preparation queue for 63s, while the semi-connected queue defaults to 1024, which is different by system default and can be viewed by cat/proc/sys/net/ipv4/tcp_max_syn_backlog c. That is to say, sending 200 fake syn packets per second without any protection is enough to burst the semi-connection queue, thus preventing the real connection from being established and responding to normal requests. The end result is that the server has no time to ignore the normal connection request-denial of service.

In terms of curriculum system construction, most companies take "mathematical thinking" as their entry point. Among them, Growth Insurance benefited from its early establishment.

However, the curriculum contents of institutions such as spark thinking, one-off mathematical thinking and talent communication have only completed phased research and development and have been put on line, and some contents still need to be developed.

Most cases that may be tried in rural areas may be subject to "summary procedure", that is, what we call "kang trial" at this moment. The "mock trial" project prepared can enable villagers to understand the real trial procedure and the majesty of the law.

For example, in the back-end system, There are tabular data, Each piece of data is preceded by a check box button, When you click the check box button, After obtaining the id, it needs to be passed to the server to send an ajax request. The server needs to record this data, To request, if we send an http request to the server every time we click, For the server, the pressure is relatively high and the network requests are frequent. However, if the real-time data of the system is not very high now, we can collect all ID for a period of time (e.g. 2-3 seconds) through a proxy function and send AJAX requests to the server at one time. Relatively speaking, the network requests are reduced and the server pressure is reduced.

If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. The end result is that the server has no time to ignore the normal connection request-denial of service. If you look at the SYN_RECV status on the server with the netstat-an command, you can see that there are a large number of connection states that are "SYN_RECEIVED"
