Select "Fine Effect-Olive Color, Emphasize Color 3" from the pop-up options. (Mouse over the option will be prompted)In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).If the message has been matched by the previous rule, iptables performs the corresponding action on the message, Even the latter rules match the current message, It is very likely that there will be no chance to perform corresponding actions on the message again. Take the above figure as an example, the message is first matched by the first rule, so the current message is "released", because the message has already been released, so even if the second rule in the above figure can match the message just "released", there is no chance to discard the message just now. This is how iptables works.
