49 Capturing and filtering traffic at command line

############################# Video Source: www.youtube.com/watch?v=lL159zajot4

To capture traffic using Wireshark from the command line, you can use tshark, the terminal-based counterpart. For example, to start capturing on interface eth0 and save the output to a file, you would use: • tshark -i eth0 -w capture.pcap • To filter the captured traffic in real-time, use the -f option followed by a capture filter expression, such as: • tshark -i eth0 -f port 80 -w capture.pcap • This command will capture only HTTP traffic on port 80.","styleRuns":[{"startIndex":0,"length":451,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":451,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CL8BELsvGAIiEwiv8v_jgd6JAxW4ZXoFHZpnLqg=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC2xMMTU5emFqb3Q0GAYyJSIRIgtsTDE1OXpham90NDAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CL8BELsvGAIiEwiv8v_jgd6JAxW4ZXoFHZpnLqg=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CL4BELovIhMIr_L_44HeiQMVuGV6BR2aZy6o"}},"secondaryResults":{"secondaryResults":{"results":[{"compactVideoRenderer":{"videoId":"l9sMdZsLoAc","thumbnail":{"thumbnails":[{"url":"https://i.ytimg.com/vi/l9sMdZsLoAc/hqdefault.jpg?sqp=-oaymwE1CKgBEF5IVfKriqkDKAgBFQAAiEIYAXABwAEG8AEB-AH-CYACqAWKAgwIABABGF0gZShVMA8=
