Wireshark-dev: Re: [Wireshark-dev] Please help me, I need to automatize the calculation of Inte
Hi,
Without going into the details of the analysis, I would suggest to use the
keyboard shortcuts to "work the GUI" from the macrorecorder, in order to
export the statistics to a CSV file. From there you could perform any
calculation you want.
Thanx,
Jaap
