best network cable tester

The production of network cable is actually very simple, one of the most important is that it access the line sequence problem, learned these you can make their own hands to create network cable. The Wire crystal Head has two kinds of practice standard, the standard is tia/eia568b and Tia/eia 568A respectively. 568A

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

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

Using a network cable to transfer files between two linux systems, sftp first sets the IP addresses of the two hosts to the same network segment. one is a virtual machine, and the other is a virtual machine network bridging mode in linux, www.2cto.com is in the VM:/etc/init. in d/sshdstartlinux: first, it is true... U

Two computers transfer files There are many ways, small QQ on the solution, a little larger can be installed by the fast-pass software to achieve the purpose, of course, with U disk is also possible. This is all right, that if the number of files or large files (more than hundred grams) of the time to do, the hard disk is a kind of, but because it is the intermediate medium of transmission, so more trouble, the following with a cable transmission of t

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

[Reprinted] The 4412 Development Board, PC, and ubuntu are connected through a network cable, and the 4412 ubuntu Today, we can see that the Development Board uses TFTP to download programs directly from ubuntu without having to download them through the burning file system all the time. I tried it and the virtual machines, development boards, and PCs won't be able to ping each other. After a long struggle,
