Linux Network Monitoring Tool ss, network monitoring ss
The ss command is used to display information about active sockets. Similar to netstat, but faster and more efficient than netstat.

Usage: ss [OPTIONS] ss [OPTIONS] [FILTER]-h, -- help this message-V, -- version output version information-n, -- numeric don't resolve service names does not parse the se
specially used to capture HTTP and HTTPS.
Wireshark can obtain HTTP and https, but cannot decrypt https, so Wireshark cannot understand the content in https
To sum up, if HTTP and HTTPS are processed, or Fiddler is used, other protocols such as TCP and UDP use Wireshark.Other similar tools

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

BKJIA exclusive statement] this economic crisis has caused great harm to large enterprises. In addition to some domestic demand types in China, many companies have begun to make decisions in the cold winter. During this period, in order to successfully launch the award and reduce corporate compensation, we have used some of the methods we do not usually use. Everything is done for employees who make mistakes and for all employees who make mistakes. Although this article describes the monitoring

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
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

NetIQ Chariot is regarded as a standard for evaluating the network performance of the application layer. It uses simulated real networks to test the performance of point-to-point or complex architectures and distributed architectures on the network, therefore, it has multiple functions such as network performance, device performance, application performance, and
In general, we conduct network testing, mainly testing network connectivity, network bandwidth, network response time and so on. Common tools include ping, traceroute, Telnet, FTP, and so on. such as testing network connectivity, you can use Ping,traceroute, if the test fire
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,
