A network packer sniffer(s), commonly referred to as a wireless sniffer, network analyzer or packet analyzer is a computer hardware or program that logs traffic passing over a digital network by listening and intercepting packets of data. The information obtained by the wireless sniffer is used to determine whether or not there are unusual or erroneous packets in the transmission of data. This will help in maintaining an effective data transmission.
In other words, the network analyzer will capture packets of information that pass through a digital network. Packet sniffing is very similar to wire tapping a telephone line. Legitimate packet sniffing is primarily used to monitor network performance and to troubleshoot problems that may occur in a network. The sniffer can also capture traffic on parts of the network using one software program. However, this will depend on whether the network is a hub or a switch. Some administrators prefer to use sniffers to obtain information from other networks as opposed to sniffing traffic or data. Extracting data from other networks can be accomplished with the help of a monitoring port.
Since data transmitted through a computer network is in digital form, packets obtained from the network are decoded from the digital form to a format that humans can understand. This will make it possible for the administrator to read the information that is being transmitted between networks. By deciphering this information, the administrator will be able to identify the root cause of the problem and fix it.
Apart from capturing data packets, there are some packet sniffers that can also generate traffic. Such devices are commonly referred to as reference devices. Reference devices are normally used to test protocols. Protocol testers can be used to create protocol-correct traffic that can be utilized in functional testing. The main objective of introducing false traffic to a network is to determine how well the wireless sniffer or packet analyzer can detect and deal with errors.
While packet sniffers are primarily used to analyze problems, they also have a variety of other applications. For instance, they can be used to detect network intrusion attempts, network misuse, debugging server communications, isolate exploited systems, monitor network usage, gather network statistics, provide data for network monitoring and filtering suspicious content from networks. All said and done, having a network packer sniffer(s) is very important if an efficient computer network desired. I hope this article helps to understand what a packet sniffer is.
