Comparison of network service platforms-one of the ice application Series Since the 1990s S, the computing industry has been using object-oriented middleware platforms such as DCOM and CORBA. In the process that enables distributed computing to be used by application developers, object-oriented middleware is an important step. For the first time, developers have the possibility that they can build distribu

Netcat, also known as the Swiss Army Knife, is a common network tool for hackers and system administrators, originally developed for file transfer and later developed many powerful features, such as the ability to perform bulk host service scans.Previously, another more common scanning tool for bulk host services was introduced: Nmap.The installation of the Netcat is also very simple, with the direct Yum in

This article introduces the use of Muduo to implement a simple topic-based message broadcast service, which is actually a "chat room" a simple extension, but chat is not a person, but a distributed system in the program. The code for this article is shown in Http://code.google.com/p/muduo/source/browse/trunk/examples/hub In distributed systems, in addition to the commonly used end-to-end communications, there are a one-to-many

normal access traffic are used to block attack packets. In this way, the DNS server will not be overloaded by attacks. FortiGate IPS can defend against DDoS attacks that exceed 0.1 million PPS per second. Figure 1: Anti-DDoS configuration of FortiGate 2. for regular large-scale DDoS attacks, such as a large number of DNS queries on baofeng.com initiated by storm audio and video software, FortiGate can formulate corresponding detection rules to

#nginx Web cache service with Sina's Open source Ncache module # # What is the Web cache Web cache located between the content source Web server and the client, when the user accesses a URL, the Web cache server goes back to the backend Web source server to retrieve the content to output, and then When the next request arrives, if the access is the same as the Url,web cache server directly outputs the content to the client, instead of sending the

1.1.1 Summary Recently, network security has become a focus. In addition to domestic plaintext password security events, there is also a major impact-Hash Collision DoS (Denial-of-service attacks through Hash collisions ), some malicious people will use this security vulnerability to make your server extremely slow. What measures do they use to make the server extremely slow? How can we prevent DoS attacks

Switch from: Provide (24x7 uninterrupted service) Starting point of design: First, the network model, epoll event trigger mechanism, reactor, and proactor are similar. Second, single thread or multi-thread In a word, based on business needs (Io or CPU computing), multithreading can make full use of the advantages of multi-core processing, but may occupy a large amount of CPU resources. In addition, multithr

the basic concept of NigixThe most common use of nginx is to provide reverse proxy serviceThen the reverse proxy describes the basic information as follows:The proxy server accepts requests as intermediaries on the client side, hides real customers, and obtains resources from the server. If the proxy server outside the Great Wall can also help us to achieve the purpose of crossing the Great Wall. And the reverse proxy as the name implies is the proxy server as the intermediary, hide the real
