Use Ntop to monitor network traffic ____ Network traffic reflects the running status of the network, which is the key data for determining whether the network is running normally. In the actual network, if the

Introduction MRTG (Multi Router Traffic Grapher, MRTG) is a tool software used to monitor network link traffic load. It obtains device traffic information through the SNMP protocol, in addition, the traffic load is displayed to the user in HTML document containing PNG format, and the traffic load is displayed in a very intuitive form (the output result example of MRTG can be obtained at the website http://w

developed to assist in TCP Parameter Optimization, but here we do not want to study the TCP Window Scale and maximum segment length, because this is not the focus of our current discussion. However, when testing a high-throughput AP, you may find it necessary to tune TCP parameters so that you can get a larger throughput on each iPerf client-For details, see DrTCP. Monitor wireless network performance usi

The security of Wireless LAN has always been one of our key issues. So how can we achieve comprehensive protection? First, we need to conduct a comprehensive analysis of the network security mechanism to see what causes the danger. Next we will conduct a wireless LAN security analysis. 1. First, determine the

isolate illegal users from sensitive network resources, thereby preventing possible illegal interception.(2) switching hubs in place of shared hubsThe risk of Ethernet interception persists after network segmentation of Ethernet central switches. This is because the network end user's access is often through the branch hub instead of the central switch, the most

After successfully setting up a wireless LAN, many users are not asking for help. Even if they constantly adjust their wireless passwords, they may be at risk of brute force cracking by malicious users.To ensure the security of the wireless network, you can use the "WiFi Guard" tool to monitor the users who attempt to access the

information system of the organization, but for small-scale units that do not have high security requirements, low-level wireless LAN can still be used. After all, this type of networking costs are very low. More importantly, effective measures can minimize the security threats of low-level wireless LAN, this allows users of small organizations to enjoy convenient networking. 1. Check for

Internet is a very effective network security model, through which it can isolate risky areas (that is, the Internet or networks with certain risks) and security areas (LAN) does not impede access to risky areas. The firewall can monitor inbound and outbound network traffic

-virus effect is compromised. As a matter of fact, with the development of new technologies, the concept of viruses has gradually evolved from the previous simple infection of boot areas and system files to automatic transmission through the network, in addition, some do not host system files, but are directly parasitic on the operating system. Web pages, e-mails, and shared directories have become the channels for spreading
