For the small and medium-sized network administrators, the most headache is how to effectively manage the enterprise network, so that the enterprise network operation efficiency is higher. Usually we in the network management is always sandwiched in the middle, we must focus on external

With the rapid development of computer network technology, network security issues have become increasingly prominent in the face of various users. According to the data obtained by the author, nearly 20% of users on the Internet have suffered from hackers. Although hackers are so rampant, the network security problem has not yet attracted enough attention. More

There are countless articles on the wireless network stability settings introduced on the network. Through these articles, we can also learn about the configuration process. So the security and stability of wireless networks. Let's make a deep analysis. We must be familiar with the use of wireless networks, but we often encounter unstable network conditions durin

There are still many things worth learning about integrated network cabling. Here I will mainly explain to you how network cabling works in integrated network cabling, this includes network cable Testing, one-by-one enabling of computers, "Hot swapping" of Network cables, an

We do not know much about wireless network settings. How can we enhance the security of wireless networks and improve the stability of network signals? The following is a detailed introduction. Although the implementation of wireless networks has been quite high at the beginning of the design, wireless network configuration is not a simple task for more new users

The author says: Before having studied once, but after a period of time, many details place already blurred. Recently deduced again, in order to retain as far as possible the derivation idea, specially writes this blog post. On the one hand for their future memories, on the other hand to communicate with you to learn.For this blog post, the following description:1.

Network packet Detection Packet Capture (sniffer): refers to the behavior of data collection on the network, which needs to be done through the NIC. Three ways to access: BSD Packet Filter (BPF) SVR4 Datalink Provider Interface (DLPI) Linux Sock_packet interface Libpcap Library Installation: Apt-get Install Libpcap-dev Common APIs Capturing data packets Find the default data

To reduce design complexity and enhance versatility and compatibility, computer networks are designed as hierarchies. This hierarchical system enables a variety of different hardware systems and software systems to easily connect to the network. When analyzing and troubleshooting network faults, administrators should make full use of the layered features of the network
