Most of the following display filters work on live capture, as well as for imported files, giving. You can even compare values, search for strings, hide unnecessary protocols and so on. The "Filter Expression" dialog box can help you build display filters. Thankfully, Wireshark allows the user to quickly filter all that data, so you only see the parts you’re interested in, like a certain IP source or destination. For display filters, try the display filters page on the Wireshark wiki. 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. 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. Note that a filter of http is not equivalent to the other two, which will include handshake and termination packets.
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
