Dual-system Ubuntu10.04 can access the internet. Win7 showed that the network cable was pulled out. Xiao Zhong installed Ubuntu10.04 i686 on the computer in the lab to play with KVM. After installation, the experience was quite good, the installation of various software packages can be easily found in the ubuntu software library. The only drawback is that the sound card does not sound well, and xiaozhong is

A pay cable TV network plans to relay an important football match. Their broadcast network and user terminal constitute a tree structure, the root node of the tree is located at the scene of the football match, the leaves for each user terminal, and other transit points for the tree's internal nodes.Signal transmission costs from the retransmission station to the

Itself is a server, a network cable, need to virtualize multiple ip addresses? The server deployment has the following requirements: Two applications need to be placed on one server. to facilitate management, you need to configure two domain names for them, and DNS is also set up by yourself. In this way, two ip addresses are required, The problem is, how can I virtualize two or more ip addresses on a ser

Solution 1: 1. Set the NIC connection mode of the virtual machine to Nat;2. Check the vmnet8 status (CMD-> ipconfig/all) in the host and find its IP address, such as 192.168.206.1;3. Set the IP address in the virtual machine to the same network segment as the above IP address, for example, 192.168.206.46, and fill in the IP address (vmnet8 IP address) just found in the gateway and DNS ). (Or enable the DHCP and Nat services of VMware, VMWare will aut

Generally, the theoretical distance of Category 5 network cables cannot exceed 100 meters. If the network cable is too long or light, the signal is unstable, and the Internet access speed is slow. If the network cable is heavy, there is no signal. To address this problem, I

During this period, the socket connection cannot be detected and exited due to network disconnection or long connection time. Technical Background: the target machine runs on vxworks, while the pc can connect to the target board through serial port and telnet. After the pc connects to vxworks through telnet, execute the shell program we have written, here we call this shell program CLI. Because the telnet client is already writable, microsoft's cmd

The main topic: to a N-point, M-edge of the graph, the minimum point cut set of the cardinality.Problem Analysis: The base of the minimum point cut set of the graph can be changed to the minimum cut. Considering the graph of single source s single-sink T, if a minimum point set is required, so that the graph is no longer connected after the point set is removed (the number of connected components is increased), simply split each point into two (in and out points), and with a capacity of 1 arc, t

Symptom descriptionA certain Bureau adopts the MA5200 + 2403F networking mode. Due to the small amount of upstream optical resources, the 2403F cascade mode is adopted in the residential area, and the cascade mode adopts five category of twisted pair wires, you can use PPPOE to access the Internet. Some second-level switch users report that the Internet access speed is slow.Alarm informationThere are many CRC verification errors on the upstream port of 2403F.Cause AnalysisDue to

Network cable is not enough, the computer can connect the router set up the Internet? OK. The router can emit a default wireless signal tp-link_xxxx in the factory state, and this signal has no password. You can use a mobile phone, notebook or pad to connect this wireless signal, open a Web browser, enter the router's management address (tplogin.cn or 192.168.1.1), you can log into the router management i

In many cases, after the computer is connected to the LAN interface of the D-LINK router through the network cable, the local connection will show unable to connect, the specific solution is as follows:1.
