To improve network management efficiency, it is necessary for us to generate a convenient and intuitive network topology map for our local area network in a timely manner. This network topology map is cleverly used, we can quickly find the source of network faults. Now, I wi

One NIC can choose different IP according to the network environmentSometimes we encounter a situation where, when participating in a company project, the network environment does not have a DHCP service, the IP configuration must be specified manually, and when we go home from work, we must change the IP configuration in order to properly surf the internet. In fact, both Windows and Linux support the confi

Win8.1 system The lower right corner of the network icon shows "unrecognized network" how to resolve First, dial-up Internet access Direct dial-up access to this fault, for the machine can not obtain IP address (broadband connection is using the PPPoE protocol connection extranet, the local connection is using the TCP/IP protocol.) The physical connection to the local connection is correct when dialing,

Due to recent business needs, a function to get all the IP in the network segment is written, as well as a function to allocate the available subnet segments/** * Calculate all IP * @param string $segment network segment ' 139.217.0.1/24 ' * @return array IP list [' 139.217.0.1 ', ' 139.217.0.2 ' ...] According to the network segment. */functionGetipbysegment ($s

The clone source's Centos7_1 network address is 192.168.140.11, and I want to change the network address of the cloned centos7_2 to 192.168.140.12. Two places need to be changed: The network configuration of the virtual machine and the Centos7_2 configuration file.If you don't know how to configure a static address, you can view the previous article:1. Configure

1, Network Division Local Area network: Small coverage, closed wide area network: distance, need to rent bandwidth Internet ISP: Self-built room, provide internet access Service 2. Computer Data communication Process Include IP address: Packet contains MAC address: Data frame 3. OSI Reference Model 3.1 Layered Model Application Layer: The program presenta

I. Introduction to the ConceptNetwork programs are divided into server-side programs and client programs. The service side is the one that provides the service, and the client is the party requesting the service. But the reality is that some programs of the client, server-side role is not so obvious, that is, mutual client and service side. When we write a network program, it is generally based on TCP protocol or UDP protocol for

I. WedgeNow that you've learned to write Python code, if you've written two Python files a.py and b.py and run them separately, you'll find that the two Python files work well. But what do you do if you want to pass a data between the two programs?This problem can be solved with your knowledge now, we can create a file, write the content that a.py want to pass to the file, and then b.py to read the content from this file.But what do you do when your a.py and b.py are on separate computers?Simila

Toll Data Network 4G Network You can use the communications company 4G Network, you should pay attention to the use of data network is charged. Note 4G network usage charges Please note that the use of 4G

1. We want to turn off the 4G network simply click "Apps" on the phone's desktop.2. Furthermore, we find the inside "set" entry.3. Then we find the inside "More network" click to enter.4. Furthermore, we click on "More Network"-> "mobile network" and then enter. 5. Then after opening the interface "

In the command line in the multi-network management is a special demand from me, but for a variety of reasons, do not want to change back to network that old way to manage the network. Let's talk about this particular need: Run Ubuntu (virtual machine) in your notebook, with a Web site project, because both in the office and at home can be simultaneously through

First, check the network cable We open "Control Panel" in the computer and we find "network and Internet" in the control Panel we found, check whether "Wlan" or "Ethernet" are connected, as shown in the following figure. Ii. Retrieve IP address information Let's see if it's an IP problem we can press (WIN+X) and then enter Ipconfig in the pop-up interface to view it. Let's see if

Brief introductionOver the past few years we have made significant progress in mobile cellular network performance. However, due to the expansion of network latency, many applications have not been improved.Latency has long been a constraint on mobile networks. Although some progress has been made in recent years, the reduction in network delays has not been keep

Fourth Chapter Network layer 1. Two services at the network layer : Virtual circuit Service (reliability guaranteed by the network) and datagram service (reliability guaranteed by the user host)2. Internet Protocol(1) Address Resolution Protocol ARP and Inverse Address Resolution Protocol (RARP): Under IP protocol, IP uses these two protocols to resolve to th

The simplest way to connect a server with a socket is to use the IP and port directly, but the Connect method in the socket class does not provide this way, but instead uses the SocketAddress class to pass the server's IP and port to the Connect method. While this is a seemingly troublesome approach, it brings us another benefit: The reuse of network addresses .The reuse of so-called network addresses is re
