Some recommendations for preventing distributed denial of service (DDoS) attacks on Cisco routers 1, the use of IP verfy unicast reverse-path network interface command This feature examines each router's packet. In all routing items that the packet reaches the network interface of the router's CEF (Cisco Express forwarding) table, the router discards the packet if there is no route for the packet source IP address. For example, a router receives a p

Win7 the way to set up Tplink routers The router picks up the power cord and connects the WAN interface with the network cable OK, enter the network name (set yourself), enter the pin on the back of the router-----complete, in the browser address bar input: 192.168.1.1--go to this address to set up the router, account number: admin password: admin OK, point left second column: Setup Wizard Next, select this in the diagram . Enter the account

first, the statistical function of the router We can monitor the user statistics on the Internet to count how many devices are currently online. The User Statistics table can understand the IP address and Mac correspondence of each user machine connected to the HiPER, and the number of packets received and sent by the user since the launch, and if a user has a particularly large number of downloaded packages, the user may be downloading or having other aggressive behavior, This reminds the adm

home, the choice of channels is one of the factors we have to consider, when there are multiple wireless devices using the same channel (such as neighbors), it is likely that the transmission is not ideal or even dropped. In the case of a channel conflict, you can choose one that works best for you in the router's configuration interface, based on all the wireless channels in the area. (It is best to avoid the top and bottom 2 bits of the occupied channel when selecting channels) In addition,

so that we can use Policy routing on them. For inbound packets, we use Tproxy to accept packets sent to the external IP address. For a return outbound packet, there will be a socket open bound to an external address, and we just need to force it to be passed locally. The value of--ON-IP is 0 because the destination port is listening and is not bound to a specific address. The value of the--on-port must match the traffic server server port. Otherwise, its value is arbitrary. --dport and--sport S

This article describes in detail how to configure multiple vrouters in the company and how to perform these operations in various situations? The following article provides detailed answers. With the development of China's routing industry, the application of multiple routers is also more extensive. Here we mainly analyze the specific configuration methods of multiple routers. Under what circumstances will

Understanding the features and architecture of Cisco routers the basic knowledge of Cisco routers is still important for a network engineer, which is the foundation of Cisco technology. This document describes the features and architecture of a Cisco Router Based on a Cisco router. Before learning about the various troubleshooting and diagnostic tools available for Cisco

discovery protocol allows routers to be discovered through IP hosts, but it is not widely used. This means that most hosts cannot quickly know whether the connection between the vro and the connected lan has failed, and it takes a long time for the IP host to detect the connection failure and exchange the replacement vro. Therefore, it is important for any device to improve the network efficiency. Using vro cluster technology can effectively solve so

called routing. This is also the origin of the router name (router, forwarder ). Bridge:1. A bridge, also known as a bridge, is a storage and forwarding device that connects two local networks. It can be used to connect a network system with the same or similar architecture. 2. Functions of the bridge: 1) the bridge only packs a small amount of received information frames without any modification.2) The bridge can use another protocol to forward information.3) The bridge has enough buffer space

Recently saw a lot of people asking about the switch, hub, router is what, function, what is the difference, the author on these questions to do some simple answers. First of all said Hub, that is, hubs. Its role can be simply understood to connect some machines to form a local area network. A switch (also known as a switched hub) works roughly the same as a hub. But there is a difference in performance: the way the hub uses shared bandwidth works, and the switch is the exclusive bandwidth. In

There are two routers in the home want to connect to use, or use someone else's network, want to pick up a router to use WiFi internet access, using a router cascade can connect two routers, convenient use of WiFi router. There are two ways to connect a two router: The first way: the route mode Cascade, the second level router and the superior router all have the routing function, two

With the development of China's routing industry, dual-WAN Port Routers are also widely used. Here we mainly introduce a cost-effective dual-WAN port router. Currently, many Internet cafes use dual-WAN Port Routers. The dual-WAN port router is very familiar to Internet cafe operators. Simply put, a dual-WAN port router is a router with a dual-wide access port, this type of router has many benefits: 1. Incre

The following article describes how to correctly use routers in Internet cafes to prevent ARP attacks. I saw on the relevant website two days ago how Internet cafes correctly use routers to prevent ARP attacks, here is a detailed description of the content. In this paper, the new generation of TP-LINK for Internet cafes Broadband Router TL-R4148 as an example to introduce, on the prevention of ARP attack th

Presumably, network administrators have a headache for configuring a large number of complicated configuration commands for Huawei routers. The following is a simple configuration command for Huawei routers. Let's take a look!1. Common User Mode (1) help description of the help System; (2) telnet Remote logon; (3) language mode switch; (4) ping the network host to check whether the network host is connected

When using the H3C SR600 series routers, some netizens may find that as long as the routers start up, the memory usage increases sharply and exceeds 50%. This is a normal phenomenon or a problem with the routers. Today, I will explain why this problem occurs. The memory occupied by H3C SR600 series routers during start

At present, China's wireless routers are developing rapidly. Here we will mainly explain the experiences of using wireless routers. Recently, I 've played with several common wireless routers on the market. I 'd like to explain my feelings so that users can buy them later. it's just a little bit of a diving old bird. I am a player who prefers p2p software. I like

This article describes the development and basic concepts, principles, and high-speed SONET/SDH Network Connections of virtual routers. I believe this article will help you. Recently, some new breakthroughs in IP backbone network equipment have paved the way for the future implementation of new Internet services. Vro is a new technology that makes some new Internet services possible. With these new services, you can control network performance, Intern

China's wireless routers are developing very fast, and many people may not understand the practical application of each function in the wireless router. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. With the development of science and technology and the improvement of people's living standards, it is very common to have more than two computers in a modern family.

The Core routing and switching devices of enterprises shoulder the important responsibilities of connecting clients and servers in the network. Therefore, the operating efficiency of enterprise routers directly determines the operational efficiency of enterprises. At ordinary times, enterprise network administrators always encounter problems such as router Management and Maintenance. Today, I will introduce some effective methods to readers of IT168 n
