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.

Enter "gdb-q loudong", "run" and the string generated above in turn, and the addresses of each register can be viewed after the program runs. It can be seen that the string stored in the RBP register that we need to view is "haabiaab". According to the structure of the stack frame, the address of the upper 8 bytes pointed to by the RBP register is the return address, and the overflow point position is RBP position +8, which is easily obtained as 128+8=136.

身为联邦调查局探员的阿特·杰弗里斯因工作失误而被降级。心情沮丧的他被安排执行一项不起眼的差事，寻找一个患自闭症的9岁男孩西蒙。杰弗里斯没费什么事就找到了目标，但这时的西蒙因父母惨遭杀害，精神上受到严重创伤，一句话都说不出来。在某种意义上说，他们两人是同病相伶。所以杰弗里斯很能理解男孩的心情。同时，多年的工作经验也告诉他，此刻的西蒙也面临危险的处境。事实也的确如此，西蒙是个智力超常的孩子，他无意中破解了军方的密码，而那项代号“水星”的计划是不惜一切代价要保守的机密。这样一来，两个人就成为被追杀的目标……
如果他们两人同气连枝，对于我们而言是个巨大的威胁，所以不必须要予以打击。
