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.

1. Normal life cycle:
As Murder, She Wrote saunters through its sixth (of an eventual 12) season, star Angela Lansbury maintains her eternally buoyant and inquisitive air as Jessica Fletcher, professional writer and amateur sleuth. Though Jessica continued to investigate murders in her home town of Cabot Cove and elsewhere (in the worlds of high finance, opera, and voodoo, among other settings), this season began the practice of guest detective episodes, introduced by Jessica as either a story she wrote or a tale told by a friend, but starring a variety of quirky investigators: An ex-football player (Ken Howard, The White Shadow) paired with a clever poodle; a television crime-show producer who solved crime in real life (Diana Canova, Soap); a stout Irish detective (longtime character actor Pat Hingle); an abrasive homicide cop (Barry Newman, Vanishing Point); as well as recurring Murder, She Wrote characters like former jewel thief Dennis Stanton (Keith Michell) and British secret agent Michael Haggerty (Len Cariou). The producers were obviously hoping to use Murder, She Wrote's popularity to spin-off new series, but nothing from this season took off and viewer resistance soon brought the practice to an end. Executives must have been surprised to discover that, though murder mysteries are plot-driven, this show's success depends heavily on the undeniable charm of star Lansbury. Still, these one-off episodes are of a consistent quality with Lansbury's, and viewers open to variety will enjoy them just as much. The rest of the season features the usual astonishing array of guests, including movie stars old (Donald O'Connor, Singin' in the Rain) and recent (Elliott Gould, The Long Goodbye), television stalwarts (Shirley Jones, The Partridge Family; Jerry Stiller, The King of Queens; Doris Roberts, Everyone Loves Raymond; Kevin Tighe, Battlestar Galactica; and Gavin McLeod, The Love Boat), and D-list celebrities to die for (Dack Rambo, Morgan Brittany, Susan Anton, and more).
