Hi, Is there any option to run tshark without dissecting the data layer? I want to get the bytes or hex of the data layer in my json output

Thanks!

Use the option --disable-protocol to stop dissecting that protocol and treat it as data instead.

Thank you for your answer! Is there any way to disable all the data layer protocols at once? Or I must disable only specific ptorocols?

That depends on what you mean by "data layer protocol":

  • For 'data link layer protocol' it is probably easier to list the protocols like --disable-protocol eth
  • For protocols on top of TCP you can use the 'decode as' option: -d tcp.port==0-65535,data
