南宋淳二年(1242年)，四川安抚制置史兼重庆知府余始筑钓鱼城。1258年，蒙哥大汗挟西征欧亚非40余国的威势，分兵三路伐宋。蒙哥亲率的一路军马进犯四川，于次年2月兵临合川钓鱼城。蒙哥铁骑东征西讨，所向披靡，然而在钓鱼城主将王坚与副将张珏的顽强抗击下，却不能越雷池半步。7月，蒙哥被城上火炮击伤，后逝于温泉寺。钓鱼城保卫战长逾36年，写下了中外战争史上罕见的以弱胜强的战例，钓鱼城因此被欧洲人誉为“东方麦加城”、“上帝折鞭处”。
SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

The outer surface is plated with oxygen-free copper, and the raw materials of the core wire are brass, bronze and miscellaneous copper. Because the raw materials of copper inside and outside are different, it is called copper clad copper. The quotation is moderate, and the quotation for miscellaneous copper is usually only half or lower than that for oxygen-free copper. The produced wire is attributed to non-standard wire, and its anti-twisting and anti-oxidation functions are better than those of copper-clad aluminum. Suitable for induction and wiring engineering with low accounting, it can lay hidden lines in the wall. However, due to the influence of raw materials, the resistance is relatively large, with a 100-meter resistance of 25-35 ohms or even more, and the signal attenuation is very large. It is not so-called all-copper. We pay attention to the distinction.
