Nothing to say, just make a backup ~ ---------------------------------------- I am a split line --------------------------------------------- According to the Payment Card checkpoint in ISO 2894AlgorithmThe luhn mod-10 method rules: 1. Multiply each digit on the card number by the weight. The rule is that if the number of card numbers is an even number, the first digit is multiplied by 2; otherwise, the number is multiplied by 1, and then the numbe

Strategy: we can see that the remainder is not equal to 1 or the number that can be divisible by 2. We only need to judge whether it is an odd number other than 1, search for 2 ^ X (mod (N) in sequence ))? = 1.Difficulty: if every time it is based on the original × 2, it will time out. At this time, we can use the same remainder theorem.AC by SWS;Question link: http://acm.hdu.edu.cn/showproblem.php? PID = 1, 1395Code:# Include

-fpm is actually an enhanced implementation of the FASTCGI protocol and has been incorporated into the PHP kernel, you can use the -- enable-fpm compilation option to enable it. php-fpm supports smooth configuration changes (through the fork new worker process) with good performance and high memory usage efficiency, this is why the configuration combination of nginx + php-fpm replaces apache + mod_cgi and apache + mod_php. 5. mod_fcgid is the fastcgi Implementation of apache and has good perfor

According to the algorithm of the payment card check bit in ISO 2894, the Luhn Mod-10 method stipulates: 1, on the card number per digit multiplied by the weight. The rule is that if the number of card numbers is even, the first is multiplied by 2, or multiplied by 1, and then, respectively, 1,2,1,2,1,2;2, if each digit times the weight after more than 9, then need to subtract 9;3, all the processed weighted numbers sum, with the number 10 modulo ope

The Apache mode rewrite module provides a rewrite engine based on the regular expression parser to rewrite URLs in real time WindowsUnder Windows, we typically use the administrator account, so enabling these two is simple: In the Apache installation directory]/conf/httpd.conf find #loadmodule rewrite_module modules/mod_rewrite.so, remove the previous annotation symbol #. If this line is not in use, add it. Verify that the mod_rewrite.so file is in the Modules folder under the Apache installat

Everything has two sides, and there is always one disadvantage if there is a benefit. Just like IPv6, it brings almost unlimited IP Address resources to the Internet, but also changes the security environment of the Internet, bringing greater risks to it. According to the information of some network attack events, although the transition from IPv4 to IPv6 has just begun, Some attackers have begun to spread

Technical Features of IPv63.1 What are the significant advantages of IPv6 over IPv4? Compared with IPv4, IPv6 has the following significant advantages: 1) The address capacity is greatly expanded from the original 32-bit to 128-bit, which completely solves the problem of IPv4 address insufficiency. the hierarchical address structure is supported to facilitate addressing; extended support for multicast and a

1. What isIPv6 IPV6 refers to the Internet Protocol (IP) version 6th. At present, we mainly use Internet Protocol Fourth edition, namely IPv4. With the global Internet highly developed today, IPV4 address resources have dried up and the internet is undergoing a transition from IPV4 network to IPV6 network. The IPV4 address is similar to the A.B.C.D format, with a total of 32 bits. Divided into four segments

When you deploy IPv6 in a WAN, an IPv6 firewall is also deployed. This article introduces some security issues caused by IPv6 and the problems that IT professionals should consider when deploying and operating IPv6 firewalls. Introduce IPv6 Firewall The first line of defense

PV6 is considered an alternative to the traditional 32-bit address space on the ipv4--Internet, which is used to solve the problem of the impending exhaustion of the existing IPV4 address space. However, since a large number of hosts and devices are connected to the Internet with IPV4, it is almost impossible to switch them all overnight to IPv6. Many IPv4 to IPv6 conversion mechanisms (e.g., dual protocol

[IPv6] Detailed description of ISATAP tunnel technologyI. Basic ConceptsISATAP (Intra-SiteAutomatic Tunnel Addressing Protocol)ISATAP is an IPv6 transition mechanism that is easy to deploy and use. In an IPv4 network, we can easily deploy ISATAP. First, you need a V4/V6 dual-stack PC. Then, you need a vro that supports ISATAP, the ISATAP router can be anywhere in the network, as long as the PC can ping it (

Why do we need to deploy IPV6? · Limitations of IPv4: 1. Limitations of address space: the IP address space crisis has been around for a long time and is the main driving force for IPv6 upgrade. 2. Security: IPv4 has no security at the network layer. Security is always considered to be the responsibility of a layer above the network layer. 3. Automatic Configuration: the configuration of IPv4 nodes is compl

Network Layer 2 (IPv4 and IPv6 addresses and related protocols) IP (internet protocol) protocol is the core protocol of the TCP/IP protocol family and the network layer of the internet. The current version number is 4, also known as IPv4. The next generation IP protocol version number is 6, that is, IPv6. As described in the network layer function, the IP layer provides the selection and forwarding function

1. Introduction IP version 6th (IPV6) is a new version of the Internet protocol after IP version 4th (IPV4) [RFC-791]. The changes from IPV4 to IPV6 are mainly concentrated in the following areas: expansion of address capacityIPV6 increases the size of the IP address from 32 bits to 128 bits to support more address levels, larger numbers of nodes, and simpler address autoconfiguration.
