![]() For both HTTP and HTTPS you'd be looking at ip.addr = 10.0.0.1 & (tcp.port = 80 || tcp.port = 443). then expression will be src host 192.168.1.1 and tcp port 80 Wireshark. If you wanted that to include HTTPS traffic (TCP port 443) you could modify it to read host 10.0.0.1 and tcp and (port 80 or port 443).įor a display filter to do the same thing w/ HTTP only you'd be looking at ip.addr = 10.0.0.1 & tcp.port = 80. For example, capture filter like host 192.168.1.1, where the value 192.168.1.1 is. There are 65535 ports available for use, and in a normal Wireshark capture. To capture only HTTP traffic to/from the host 10.0.0.1, for example, you could use the capture filter host 10.0.0.1 and tcp and port 80. All of the messages exchanged in a network use a logical port. There is no method to get information filtered out. They are defined before starting the capture. To capture only HTTP traffic to/from the host 10.0.0.1, for example, you could use the capture filter host 10.0.0.1 and tcp and port 80.

If you're going to be doing a long-term capture and you want to limit the size of your capture files you'll probably want to use a capture filter. Display filter syntax is detailed here and some examples can be found here and a port filter for tcp is tcp.port and for udp is udp.port .The master list of display filter protocol fields can be found in the display filter reference. The basics and the syntax of the display filters are described in the User's Guide. You can learn more about Wireshark display filters from the Wireshark wiki. The capture filter syntax is detailed here, some examples can be found here and in general a port filter is port . Wireshark uses display filters for general packet filtering while viewing and for its ColoringRules.You can select an interface in the welcome screen, then select Capture Start or click the first toolbar button. Display filters are used to filter out traffic from display but aren't used to filter out traffic during capture. The following methods can be used to start capturing packets with Wireshark: You can double-click on an interface in the welcome screen. ![]() The syntax you're showing there is a Wireshark display filter.
