Centos7, The service is no longer started using init-style scripts, Instead, the unit file is used, Therefore, commands like service iptables start can no longer be used in centos7, Therefore, service iptables save cannot be executed. At the same time, firewall is used to replace the original iptables service in centos7, but don't worry, we just need to install iptables and iptables-services through yum source (iptables are usually installed by default, but iptables-services are not installed by default in centos7). After installing iptables-services in centos7, the rules can be saved by the service iptables save command, as in centos6, and the rules are also saved in the/etc/sysconfig/iptables file.

In addition to solving the port problem of A, the serial number problem also needs to be paid attention to. The serial number corresponds to the sliding window. The fake TCP packet needs to be filled with the serial number. If the value of the serial number is not in the sliding window of B when it is sent to B before A, B will actively discard it. So we need to find the serial number that can fall into the sliding window between AB at that time. This can be solved violently, because the length of a sequence is 32 bits, and the value range is 0-4294967296. If the window size is like 65535 under Windows I caught in the above figure, I only need to divide, and I know that at most I only need to send 65537 (4294967296/65535=65537) packets to have a sequence number fall into the sliding window. The desired value can be calculated quickly by exhaustion on multiple control hosts.
