You create a Wireshark filter with one or more Wireshark clients, then select which packets to capture for further analysis with Wireshark. Creating Wireshark filters is a very simple process. You can see how long a DNS request took, for example, or how many times a TCP connection has been established.Įven if you aren’t familiar with Wireshark yet, creating filters for your Wireshark campaigns will soon become second nature. Real time transfer allows you to see the details of each step of the transfer process. Most Wireshark clients come with a special packet capture device that allows you to capture data that is in real time. With Wireshark, you can even examine the packets that are leaving your system.Īnother useful feature of Wireshark is its Real Time Transfer mode, which allows you to easily determine how much of an IP packet transferred during the course of its journey through your network. You can determine which packets are legitimate traffic, and which ones are trying to infect your system. In addition, Wireshark offers several powerful features for inspecting the “packet tree.” Packet trees are simply a list of all the packets (outbound and inbound) that enter your network over a certain port.īy setting up a packet tree, you can view all the inbound traffic going into your LAN. This information can help network administrators pinpoint problems and avoid costly repairs. It displays Wireshark packets that match a certain pattern, compares the version number of the packet to the version number of the protocol, and reports on trouble codes that indicate problem areas such as security flaws. With this feature, Wireshark can diagnose your network protocols. Wireshark also offers a Network Diagnostic tool. For example, you can set up one or more capture windows for FTP, Telnet, or SMTP traffic. It lets you set up a number of “filter windows” to capture different types of traffic. By default, Wireshark has an easy-to-use filter window feature. Wireshark offers many useful capabilities for packet filtering and monitoring.

Also, you have an open option to send the data captured to your regular mail box or your FTP. The biggest advantage is that you can look up IP addresses, username, or any other relevant details about the user behind the sniffed data. Once you have sniffed the data, you can then use tools to further analyse it.

In other words, it helps you “sniff” (the IT term for sniffing) a packet of data. Wireshark is a free tool for finding, detecting, and tracking packet sniffers.
