The "Filter Expression" dialog box can help you build display filters. For display filters, try the display filters page on the Wireshark wiki. Move to the previous packet, even if the packet list isn’t focused. In the packet detail, opens all tree items. Move to the next packet, even if the packet list isn’t focused. For example, to capture only packets sent to port 80, use: dst tcp port 80Ĭouple that with an http display filter, or use: tcp.dstport = 80 & httpįor more on capture filters, read " Filtering while capturing" from the Wireshark user guide, the capture filters page on the Wireshark wiki, or pcap-filter (7) man page. In the packet detail, opens the selected tree items and all of its subtrees. If you want to measure the number of connections rather than the amount of data, you can limit the capture or display filters to one side of the communication. Capture several seconds of packets, then click the red square in the toolbar to. Note that a filter of http is not equivalent to the other two, which will include handshake and termination packets. After double-clicking on the interface name, Wireshark will begin capturing. I used the following Capture Filter ip matches /./././. Ping packets should use an ICMP type of 8 (echo) or 0 (echo reply), so you could use a capture filter of: icmpĪnd a display filter of: icmp.type = 8 || icmp.type = 0įor HTTP, you can use a capture filter of: tcp port 80 4 I am trying to customize Wireshark capture such that is captures all IP addresses (both source and destination) with the IP address format .100.
