TCB (TCP? Transport Control Block is a transport protocol data structure that contains all the information of the connection (in fact, in many operating systems, it is a queue used to process inbound connection requests. The queue holds TCP connection items that are in a half-open state and items that have established a full connection but have not yet been extracted by the application through an accept () call). The amount of memory occupied by a single TCB depends on the implementation of TCP options and other functions used in the connection. Usually a TCB has at least 280 bytes, which in some operating systems has exceeded 1300 bytes. The SYN-RECEIVED state of TCP is used to indicate that the connection is only half open, and the legality of the request is still questioned. An important aspect worth noting here is that the size of TCB allocation space depends on the SYN packets received-before the connection is fully established or the return reachability of the connection initiator is verified.

8-11 Constant Magician: Modify the program you wrote to complete Exercise 8-10 and pass a copy of the magician list to the function make _ great () when calling it. Since you do not want to modify the original list, return to the modified list and store it in another list. Use these two lists to call show_magicians () to make sure that one list contains the original magician's name and the other contains the magician's name with the word "the Great" added.

Many people will say when they see this case, how can human nature be so cruel, so they should reflect on human nature. It is necessary to reflect on human nature, but human nature is also transcendental. If the order behind dark human nature cannot collapse, the so-called profound reflection can only float on the surface.

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.
