A few days ago, security researchers discovered a botnet worm called psyb0t, which can attack DSL modems and routers. This worm can search for and exploit specific devices with open ports. The attacked device also has a weak password. Once a worm enters a vro, it can do whatever it wants, block the port, leak sensitive information, and attack other networks. In this article, I will analyze the router types that are vulnerable to this specific worm att

now very mature in China. Benefits Multi-line bundling technology not only helps users greatly increase bandwidth and network speed, but also enhances system stability and facilitates network operation and maintenance. Currently, most VPN Router systems use a line at the headquarters to handle data volumes from several or even dozens of branches and mobile users. Especially in asymmetric lines similar to ADSL, the uplink bandwidth is originally narrow, resulting in overwhelmed data volume at th

Users who use wireless routers have encountered frequent disconnection problems. Here we mainly explain the solutions and causes of this problem. In recent Internet forums, many netizens have reported that home routers may experience a 24-hour disconnection. In fact, this may be a means for operators to prevent account theft, users do not have to worry too much. However, in addition to the quality problems

Speaking of the performance of the vro, I would like to give you a brief introduction to what is a vro and what a vro is used! A router is a network device that connects multiple networks or CIDR blocks. It can translate data between different networks or CIDR blocks ", so that they can "read" each other's data to form a larger network. Vro has two typical functions: Data tunnel and control. The data channel functions include forwarding decision, backplane forwarding, and output link scheduling,

Holding this view will certainly question the availability of the router. But in fact, whether in reality,

rate is not equal, then the queue will eventually disappear, and if it lasts less than the queue input rate, the queue will grow longer, which is common sense, but these are the basis for in-depth analysis.3. Conclusion we can see from the analysis, the increase in service resources a little bit, do not need to increase too much, we have to achieve the effect is, the deviation of an angle, so that the service output curve and queue input curve final intersection can be:Reality: The analysis and

forward according to the same working method, and so on until the data packet reaches the destination vro.There are two different ways to maintain the route table. One is to update the route information, publish some or all of the route information, and the router learns route information from each other to master the topology of the whole network, this type of routing protocol is called the distance vector routing protocol. The other is that the router broadcasts its own link status informatio

Xiaoming House is a three-room two halls, the room is larger, more partitions, using a tl-wr886n wireless router. But there is a bedroom and bathroom signal is poor, mobile phone speed slow, watching video is not smooth. The following figure: Heard that two wireless routers can bridge, do not pull the cable can amplify the wireless signal, xiaoming plans to buy a new wireless router to bridge the amplification signal. Tp-link staff told Xiaoming, jus

Now routers are a very common tool in our daily life, he can achieve a number of computers at the same time network, almost every household has installed a router, not only the computer can connect the network, even mobile phones, ipads can be online, but this also brings a disadvantage, is once the router has failed, All electronic devices are disconnected, especially when the router is sometimes prompted to import errors, in which case

At present, wireless local area network is basically through wireless router to network, wireless LAN can be efficient Internet and wireless router status is closely related; Unfortunately, wireless routers after a long period of time, often appear a variety of "strike" phenomenon, if not in time to exclude these phenomena, Then the network efficiency of WLAN will be affected obviously. In view of this, this article will be a frequent occurrence of wi

In the days when wired network is ubiquitous, the "figure" of WLAN is moving closer and nearer to us, which is very much in step with the wired network. Considering the current wireless LAN is through the wireless router to network, wireless LAN can be efficient Internet and wireless router status closely related; Unfortunately, wireless routers in the long hours, often appear a variety of "strike" phenomenon, if not in time to exclude these phenomena

Broadband routers are still commonly used. So I studied the practical application of broadband routers and shared them here. I hope they will be useful to you. How can I use a Broadband Router? That is, how to use a Broadband Router to establish a network? Before using a Broadband Router for networking, it is best to first install the network card for each computer, add the basic protocol, there is no trou

There are many things worth learning about wireless routers. Here we mainly introduce the advanced options of wireless routers to solve IP conflicts. Now many common consumers buy wireless routers, generally, only a relatively small part of functions are used, but the wireless connection function of the wireless router is used to access the Internet or transmit d

I believe that users who use Cisco routers have some knowledge about the configuration of Cisco routers. Here we mainly analyze how to use the Cisco router configuration master port OSOLE to connect VT100 and compatible terminals, and pass Win 3. X or Win 95 terminal simulation program for configuration and other router configuration methods, as a port device connecting to the WAN,

D-Link and trending network routers discover Remote Arbitrary Code Execution Vulnerability HP's Zero Day Initiative (ZDI) discloses a 0-Day vulnerability in D-Link and trend network routers that allows attackers to remotely execute arbitrary code. The vulnerability was reported to ZDI by the security researcher Ricky "HeadlessZeke" Lawshae on April 9, August 2013. ZDI reported the vulnerability to the rout

. That is, 2nd routers use the wan port access network or 2nd routers use the lan port access network. The two methods are described in detail as follows: www.2cto.com 1. The wan port of the wireless router is connected to the lan port. This method has the disadvantage that the computers connected by the wireless router cannot access other computers in the LAN. The reason is as mentioned above. However, thi

Cisco plays a very important role in vro enterprises. It is very important to know some knowledge about common configuration commands of Cisco vrouters. So I studied how to use common configuration commands for Cisco routers. I would like to share them with you here for your reference. Access-enable allows the router to create a temporary Access list entry in the dynamic Access listAccess-group: Apply the Access control list (ACL) to the interface.Acc

Differences among hubs, switches, routers, reconnections, gateways, and bridges 1. a hub, also known as a HUB, works on the first layer of the OSI Layer-7 structure and is a shared-bandwidth device, receives data broadcast. Generally, the LAN uses a Star Connection topology, and each workstation is connected to a hub. Because of the bandwidth sharing feature of the hub, the network utilization efficiency is extremely low. Generally, the hub is not use

Happy New Year! A few days ago, I just introduced several well-sold broadband routers on the market. To prevent some new users from setting up vrouters after purchase, therefore, I would like to introduce several things you need to pay attention to when setting up a vro. At present, most broadband routers are stupid products. Users only need to understand some computer knowledge and simply take a look at th
