Too many errors in data transfer could slow down your connection as the server attempts to resend the same data over and over. Since the source, destination, and overall journey of each data packer is captured and analyzed, you’d be able to detect issues such as slow or under-performing web servers. By using Wireshark’s filtering and analysis tools, you’ll be able to narrow down the scale of the packages that could be responsible for the network error. Troubleshooting Connection ProblemsĬapturing a portion of data packets going through the network connection is the first step towards error diagnosis. Related: What Is Packet Sniffing and How Can You Stop Sniffing Attacks?īy analyzing captured data packets using Wireshark, you’ll gain information on how and when data moves around in your network and whether there’s any activity you don’t recognize. If the network you’re sniffing is anything but your own private network-a public Wi-Fi connection, for instance-sniffing could be unethical or illegal depending on the data you’re observing and collecting. Sniffing isn’t a privacy-friendly practice.
The goal of sniffing is to monitor and scan the data entering and leaving the network to "sniff out" malicious or problematic data flow. Packet sniffing is the practice of observing, collecting, and logging data packets flowing through a network.
