One, the most commonly used for Wireshark is the filtering of IP addresses. There are several cases: (1) The filter of the packet with the source address 192.168.0.1, that is, the packet fetching the source address to meet the requirement. The expression is: ip
Select capture by applying packet-capture filtering | Options, expand the window to view the Capture Filter Bar. Double-click the selected interface, as shown, to eject the Edit Interface settints window.The Edit Interface Settings window is displayed, where you can set the packet capture filter condition. If you know the syntax for catching packet filters, enter it directly in the capture

Ip.addr = = 10.1.1.1 Displays packets with a source or destination IP address of 10.1.1.1. Ip.src! = 10.1.2.3 or IP.DST! = 10.4.5.6 Displays packets that are not

to control the number of captured data to avoid generating too large log files.The display filter is a more powerful (complex) filter. It allows you to quickly and accurately find the required records in the log file. The syntax used by the two filters is completely different. Capture Filter Syntax: Protocol direction host (s) value logical operations other expr
Apply button on the right, or enter to make the filter effective. The contents of the input box are also the contents of the current filter (the contents of the current filter are reflected in the input box) 4.

This shows the importance of capturing filters.For example, we want to crawl only the communication with the 80 port, then we can set the filter rule "Port 80".650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" image "border=" 0 "alt=" image "src=" http ://s3.51cto.com/wyfs02/m02/79/95/w

We use Wireshark to capture packets, but we do not know how to analyze these packets. We cannot extract the data we need from a large number of packages. The following describes the wireshark filtering rules. Filter source IP addresses and destination
