This is best for your host or this system administrator to check if you are unsure. The origin has a firewall (or rate limiter) that blocks our requestThis is the most common cause of intermittent 522 errors. The key thing to check out initially is-

ConceptUsing the BPF (Berkeley Packet filter) toolset combined with the Iptables XT_BPF module enables high-performance packet filtering to address large-scale DDoS attacks. BPF Tools contains a simple set of Python scripts that are used to parse the Pcap file, and others are primarily used to generate BPF bytecode.First, download and install BpftoolsDownload the zip file in Https://github.com/cloudflare/bpftools, or you can download it via git, and t
DemandFirst make sure you have an own domain name, then log in to CloudFlare and add your domain name. Follow the instructions and use the default values given by it. You will have cloudflare to host your domain, so you need to adjust your registration authority settings. If you want to use a subdomain, add a ' a ' record to it. Currently, any IP address is available.Ddclient is a Perl client that updates d
Investigate how CVE-2015-5477 CloudFlare Virtual DNS protects its users
Last week, ISC released a patch to fix a remote vulnerability in the BIND9 DNS server. This vulnerability causes the server to crash when processing a certain data packet.The announcement indicates that an error occurs when the server processes a TKEY-type query. This error causes assertion fail, which causes the server to crash. Because assertion occurs in the query parsing proc
CloudFlare is the world-famous CDN service provider, its free package is enough to meet the average user. Optimize the load speed of the website, cache the static resources, distribute the content near the local area to protect against the DDoS attack. In short, very good, very honest. But in the celestial many nodes are sealed, its own DNS was sealed, and Google and FB, the same as the end of the people (in fact, we are).

COM objects are encapsulated entities that provide services to users. This should be similar to the Class Object in C ++. But sometimes the COM object is treated as the class that provides services. The COM Object also encapsulates the data and provides interfaces. But there are some differences with the class. The data in the class can be declared as public, and
This article provides a programming guide to the programmers who just contacted COM, explaining the inside of the COM server and how to write your own interface in C + +.

All the best programmers do their best to make their written programs more reusable, because it allows you to quickly write more robust and scalable programs.
There are two choices to make code reusable:
1. White box: The simplest one is to copy your program to another file.
2. Black box: It involves connecting a compiled piece of the program. So the compiled black box class library that the client can invoke is called a component.
. NET also provides dev
