Article title: the network management tool allows the network card to switch freely on the hand. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
In many cases, you need to enable or disable the Nic device. In most cases, you n

Tool Name:Solarwinds engineer Edition
Www.solarwinds.net
Recommendation reason: Some readers said: "in less than an hour, I downloaded and installed the Authorized Version of solarwinds from the website. Soon, I will be able to prepare a line usage report, and the line usage and basic response time functions are very good. In addition, the data will be saved, this allows me to view data for one week, one month, or one year."
As the name suggests, TcpDump can completely intercept the "header" of the packets transmitted in the network for analysis. It supports filtering network layer, protocol, host, network or port, and provides logical statements such as and, or, not to help you remove useless information. Tcpdump is a free network analysi

I wrote an article earlier:
IOS development-image search (source code + resolution)
Many of my friends are curious about how I got Baidu's image search API, which is actually very simple. The network packet analysis tool "Charles" can be easily implemented.

IfconfigInterface tools ()Ifconfig is a tool used to view, configure, enable, or disable network interfaces. You can use this tool to temporarily configure the IP address, mask, broadcast address, and gateway of the NIC. You can also write it into a file (such as/etc/rc. d/rc. Local ).After booting, the file will be read and an IP address will be set for the NIC1
vswitch, connect one by one, and check whether the connection is normal until the connection is interrupted. Then we can determine which network cable is faulty, find the problematic host through the network cable. . Virus detection and removal can generally solve the problem.
However, we can see that this workload is very large. If there are enough switches and there are more than one faulty computer, it

In small and medium-sized enterprises, administrators responsible for network management are also responsible for ensuring network security. Similarly, the requirements of security management and network management are integrated into a broader field of network operations.Network management tools are numerous and expen
Many companies are upgrading their wireless networks to 802.11n to achieve higher throughput, wider coverage, and higher reliability, while ensuring Wireless LAN (WLAN) to ensure sufficient network capacity and coverage. Next, we will discuss how to use iPerf to measure network performance. This is a simple and easy-to-use tool for measuring the throughput, loss,
