If the Path of the Momo web server is improperly handled, it can be a forward proxy (idc machines/cannot access the office network) The Path of a web server in Momo is not properly handled. It can be a forward proxy. It is an idc machine and can be worn in the idc, but cannot access the office network. (Partition _ tables) The problematic web server is chatst.imm

At present, most webmasters use virtual hosts, while IDC service providers in China are uneven, and there are many security differences. Most IDCs use virtual host management software. After you install and complete the settings, an IDC website, including the overall service, will be ready. Therefore, all security measures are automatically set by the software. The benefits of such software are obvious, con

the Filter mechanisms are mounted on the driver level. It can completely defend against all dos/ddos attacks (synflood, ackflood, udpflood, icmpflood, igmpflood, arpflood, and full connection). For CC attacks, DosNipe V8.0 has been released, this core is extremely efficient and secure. Based on the past defense against all denial-of-service attacks, a new anti-CC attack is added. The new algorithm can efficiently defend against all CC attacks and their variants, with a recognition accuracy of 1

When a power outage occurs in a medium-sized enterprise data center, what is a power switch? What is a medium-sized data center? The number of servers is more than 100, and the number of servers is less than 1000. Why do enterprises have to worry about power outages? The self-built IDC of medium-sized enterprises cannot have such high redundancy as IDC, so it is inevitable that there will be a power outage.

Currently, no database product is dedicated to cross-IDC optimization. Theoretically, the best solution adopted by the industry is based on the Paxos protocol (currently only implemented by google, google f1), today we only discuss considerations for MySQL in this regard: The following problems are basically designed for cross-IDC scenarios: 1. MySQL Data Synchronization across multiple IDCs for Data Consis

It can be seen that the order of document writing, from the feasibility study report to the development progress monthly report constitutes the overall document of the IDC charging system, throughout the entire life cycle of software engineering. The first IDC charging system and soft work video are the basis and basis for compiling documents. At first, it was a feeling of no way to start. First of all, we

First of all, thank Senhwaiten for our support of this IDC room visit, thanks to the old boy education to give us the opportunity to visit the engine room.Start our IDC Room tour nowUnder the leadership of Seon-hwa Guo Mong Mentor and Seon-Hwa Gao Mentor, we came to the inside of the engine room.

Demand:Need to transfer the original computer room server and re-planning the new IDC Room server business, so the original entire business to be split and migrated. The following is the original computer room architecture diagram, the server between the login for the secret key login, and 192.168.111.30 for the springboard machine, can only be connected to other servers through this machine, other machines can not connect with each other. Gateway is

Today, we visited the computer room of Beijing Sen Hua Yi Teng. This is our first time to the computer room, thank you very much the old boy education gave us this opportunity. NBSP;IDC Room management is relatively strict, before going in must pass access control, security measures very strict, temporary visitor card , at the door security check the body whether there are prohibited objects, can go in.

Background: The recent development of new products after the mission has been looking for good IDC and high-quality hosting services busy. The demand comes from our focus to solve the problem that the old version of the product faced by users at home and abroad is slow or not connected.In addition to the use of high-performance, scalable scenarios for the architecture technology, a better user experience can be achieved only by ensuring high quality o

IDC promotes service strategy to pick up the end of buying spree Near the end of the year, all walks of life opened up the end of the year-end promotional curtain, as the Enterprise Office infrastructure Equipment server also quietly joined the ranks. As a result of this year's economic recovery, the increase in corporate orders, coupled with the financial crisis last year to allow many companies to cancel the purchase of the server plan, so that com
