WiFi packet sniffing has become more prevalent as the growth of WiFi networks makes them an easy target. Network sniffer tools are available as software and can be found for just about any platform that you use. Dedicated hardware solutions are often used by network engineers. Packet sniffers are also known as network sniffers. What is a Packet Sniffer?Īccording to, a packet sniffer is a hardware or software tool that intercepts data flowing through a network. Footers may be used for error correction and other functions.
The header usually contains the IP addresses that the packet originated from and its destination. Large messages, such as e-mails and other transferred files, are broken into packets before being transmitted over the network.īesides the actual informational content of the data packet, it also contains a header and footer containing packet details based on the protocol being used for transmission. For instance, the maximum transmission unit (MTU) on the Internet’s IP protocol is 1500 bytes. There is a maximum limit to the size of a packet depending on the protocol being used. The length of a packet is measured in bytes. What is a Data Packet?Ī data packet is a small, discrete amount of data that is sent over a network such as the Internet. There are software tools that can assist in this endeavor, and we will show you how to use a free packet sniffer application. We’ll talk about what it is, why it’s done, and how it relates to network security. Today we are going to discuss the practice of data packet sniffing. What You Need to Know About Packet Sniffers!
