In the last few days because of the Philippine shooting of Taiwanese fishermen in the "Taiwan-Philippine Hacker War", Taiwan hackers once captured the Philippine government's DNS server, forcing the Philippine hackers openly "begging for mercy." DNS security problem has become the focus of research at home and abroad again. And recently, the online has also burst out "54DNS" hijacking incident. This hijacking by hackers using broadband router defects

The third step : The name is OK now we click on " Wire

This article introduces the whole WAN configuration process with specific operation examples, and introduces the configuration principles and implementation steps. We also introduced POF and FR technologies. Synchronous Serial Interface 1. This section describes the similarities between E1, T1, and T3.

When using the LAN router configuration method, the LAN router configuration method is often optimized, as well as the WAN port connecting to the wireless router and related problems. Here we will introduce the solutions to many problems involved. Summary: Lan router configuration methods With the popularity of wireles

It is very helpful to know some knowledge about vro configuration. The following describes Frame-Relay in different vro configurations in detail. With the rapid development of network technology and the wide application of Internet, the requirements for communication media are getting higher and higher. Frame-relay) is rapidly popularized with stable communication, fast speed, and preferential prices. The key to making good use of Frame relay is vro configuration. The following describes several

Network Transmission of some key business data of some enterprises or organizations requires high reliability of network equipment and convenient maintenance. There are multiple backup technologies for Cisco routers. Here we will introduce the router's own backup technology and line backup technology. Generally, a router is a bridge between a LAN and a wan. The so-called router's own backup technology is designed to solve a router's own hardwa

There are multiple backup technologies for Cisco routers. Here we will introduce the router's own backup technology and line backup technology. Generally, a router is a bridge between a LAN and a wan. The so-called router's own backup technology is designed to solve a router's own hardware (such as memory, CPU) or software IOS fault or local port fault, network breakdown caused by the failure of the port or line of the connected local area device. Th

Many junior network administrators ignore security settings when using Cisco routers, and the following three are ideal for novice users to configure network security when using Cisco routers. One, the security configuration of the router "access control" 1, the administrator who can access the router is strictly controlled. Any maintenance needs to be documented. 2, the

If a Cisco Wireless Router is improperly configured, problems such as disconnection and disconnection may occur. It is very important for us to have a deep understanding of the details in Cisco wireless router configuration. Next we will introduce the relevant knowledge in detail. As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has

A home broadband router is a broadband router with a smaller number of users, such as a 4LAN-port router, which allows 4 computers to surf the internet at the same time. If a home/dormitory/small office has multiple computers that need to be connected to the Internet at the same time, using a router to form a small loc

Broadband routers are still commonly used. So I have studied the optimization techniques of broadband routers. I will share them with you here and hope they will be useful to you. Surfing the Internet makes it necessary for us to deal with broadband routers, But we seldom look at it during our use. Even if the network is faulty, few believe that these faults are related to routers. In fact, a vro is the same as other network devices. When we set or maintain the

At present, broadband routers are widely used. Here we will mainly explain the optimization technology of broadband routers and surfing the Internet, so we will inevitably deal with broadband routers, but in our use process, I seldom look at it, even if the network is faulty. Few believe that these faults are related to routers. In fact, a vro is the same as other network devices. When we set or maintain the router improperly, it may encounter various

For the Cisco router security configuration command family, the following are 10 configuration commands, which are expected to be good for everyone. When talking about configuring a new Cisco router, most configurations depend on the type of the router and the purpose of the service. However, each administrator has his/her own command list for configuring each

In today's information society, people are increasingly demanding data communication. As the core equipment of the IP network, vro has become a key technology in the information industry.Vro A router is a packet forwarding device that works at the network layer of the OSI reference model. The router forwards data packets to achieve network interconnection. Although routers support multiple protocols, such a

Wireless Router fault description In practical applications, many users directly use the ADSL-related information after purchasing a wireless router. The following problems may occur: "I use a wireless router to share the Internet. The speed is fast and slow !" "My laptop is only 10 meters away from the wireless router
