Like any other packet sniffer, Wireshark does three things: Wireshark is the most often-used packet sniffer in the world. Installing Wireshark on Linux: sudo apt-get install wireshark This becomes very effective in conducting a traffic analysis, which can be used to troubleshoot problems by locating the source.īeing a very powerful network sniffer, Wireshark is used popularly used by: Once these packets are captured, Wireshark allows us to inspect the contents of a packet, and monitor your network at a granular level. When two or more devices communicate, a large number of packets are sent over a network and these packets can be captured for further analysis. A packet is a data component that is sent over a computer network. To analyze and manage traffic, you can choose a technique that combines the benefits of both these approaches.Wireshark is a packet analysis tool and is also used as a protocol analyzer. Despite its effectiveness, it is not necessary in all cases.
This technique is also useful for extensive analysis of certain areas where specific information is wanted. Packet capture works on the concept of mirroring of the data packets and is useful for deep packet inspection, measuring response times of applications, and monitoring server and network and user behavior. You can easily analyze network traffic abnormalities by drilling down into individual conversations and troubleshoot issues without allocating more resources, time, or memory. With this method, you won't require much storage space as the data is sampled. The predominantly used flow analysis, such as NetFlow, sFlow, or any other flow-based methods, gives a very effective and broad view of what's happening across the network, including any abnormalities in network traffic. There are two widely used standards to analyze network traffic in detail: flow analysis and packet capture. Analyzing network traffic can be challenging when you need to pinpoint an actual problem.
