In this case, you want both to be true, so you want tcp and port 25565, or alternatively, tcp & port 25565. For an alternative syntax that uses an and, you'll see this further down:Ī parenthesized group of primitives and operators (parentheses are special to the Shell and must be escaped).Īs you can see, your filter options (or primitives) should be grouped using an operator. I don't think the syntax is well explained in it (or I'm not reading the right part), but as you can see, tcp port 21 is a valid filter and what you're looking for. Wireshark, by default, considers traffic to or from ports (as well as 3128, 3132, 5985, 8088, 11371, 1900, 2869, and 2710) as HTTP traffic, so it shouldnt be necessary to use 'Decode as.' to recognize port 8080 traffic as HTTP. E.g., 'ether src foo', 'arp net 128.3', 'tcp port 21', At the transport layer, you can specify a port using this display filter: tcp.port 80 At the network layer, you can limit the results to an IP address using this display filter: ip. Possible protos are: ether, fddi, tr, wlan, ip, ip6, arp, rarp, decnet, tcp and udp. Qualifiers restrict the match to a particular protocol. Automatically scrolls down to display the newest. That syntax is specified in the pcap-filter man page. Makes a packet filter based on the node or port number of selected packet. At the network layer, you can limit the results to an IP address. Wireshark uses display filters for general packet filtering while viewing and for its ColoringRules. At the transport layer, you can specify a port using this display filter: tcp.port 80. At the application layer, you can specify a display filter for the HTTP Host header: http.host ''. We can add filtering to capture only packets that are interesting to us. You can filter on a HTTP host on multiple levels. You want sniff(filter="tcp port 25565", prn=test).
