When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.

Focal length, also known as MF. It refers to manual focusing. When taking photos, you need to click on the screen to determine the focus.
This principle means that there are no methods in each interface that subclasses cannot use but must implement. If not, the interface must be split. It is better to use multiple isolated interfaces than to use a single interface (an interface where multiple interface methods are assembled into one).
Since it is called, as the name implies, the front section is separated like toes. Of course, this is not just for the sake of good looks. There are other functions and ideas. We will talk about them later.
The real threat lies in amplification attacks using reflection principles, In the network service protocol provided by the reflector, There needs to be an asymmetric amount of request and response data, The amount of response data needs to be greater than the amount of request data, The larger the ratio of the response data to the request data, the larger the amplification factor of the amplifier, and the more obvious the effect of consuming bandwidth resources caused by amplification attacks. However, the number deployed on the Internet is very small, so amplification using the network service cannot achieve a large flow and can only be used as an auxiliary means.

James Norton and Robson Green return as the unlikely 1950s crime fighting duo, Vicar Sidney Chambers and Police Inspector Geordie Keating, in the third series of Grantchester, produced by Kudos. The six-part series is based on The Grantchester Mysteries by James Runcie. Tessa Peake-Jones is back as Sidney’s sharp tongued housekeeper Mrs Maguire who keeps the vicar in check; Morven Christie reprises her role as Sidney’s forbidden lover Amanda; Al Weaver returns as the timid curate Leonard Finch; Kacey Ainsworth is back as Geordie’s long suffering wife Cathy, Lorne MacFadyen puts his police helmet back on to play DC Phil Wilkinson and Seline Hizli returns as the feisty police secretary Margaret. And of course it wouldn’t be Grantchester without the return of the gorgeous black Labrador Dickens.
