The connection is formally closed after waiting, and all resources (including the port number) are released."Question 1" Why is the handshake three times when it is connected and four times when it is closed?A: The syn+ack message can be sent directly after the server receives the SYN connection request message from the client side.

three handshake familiar, four times wave estimated that the so-called Four waves (Four-way Wavehand) that terminates the TCP connection, When disconnecting a TCP connection, the client and server are required to send a total of 4 packets to confirm the disconnection of the connection. In socket programming, this process is triggered by executing close on either side of the client or service side, as shown in the entire process:Figure 3 TCP Four

With the increasing degree of software automation, database maintenance is a serious problem found in software development.

last few lines can be a good way to reduce the number of time_wait sockets, but for squid, the effect is not small. This parameter controls the maximum number of time_wait sockets, preventing squid servers from being dragged to death by a large number of time_wait sockets.Reference articlesHttp://www.cnblogs.com/tankxiao/archive/2012/10/10/2711777.htmlhttp://blog.csdn.net/whuslei/article/details/6667471http://molewan.blog.51cto.com/287340/114592http://www.jellythink.com/archives/705Https://wiki

. At this point, 3 handshake completed, connection established!State transitions when disconnectingBecause TCP connections are full-duplex, disconnecting is a little more hassle than establishing a connection. The client sends a FIN message to the server, requests a disconnection, and its status changes to Fin_wait1. After the server receives the fin, an ACK occurs to the client, and the server state changes to close_wait. When the client receives an ACK, it enters the fin_wait2 state. The conne

transferred to the established state. SYN attack is the client in a short period of time to forge a large number of non-existent IP address, and to the server to continuously send SYN packets, the server replies to confirm the package, and wait for client confirmation, because the source address is not present, so the server needs to continue to resend until time-out, These bogus SYN packets take the time to occupy the disconnected queue, causing the normal SYN request to be discarded because t

The first party to close will perform an active shutdown, while the other side performs a passive shutdown.(1) Client A sends a fin to turn off customer A to Server B data Transfer (message segment 4).(2) Server B receives this fin, which sends back an ACK, confirming that the serial number is received plus 1 (message Segment 5).
