I need to convert a pcap-ng/ now a pcap file to a raw file for being able to analyse it with multimon-ng. Any recommendations? It should be possible, but I am not aware how it should be done.
Open Wireshark and go to:
Menu -> File -> Export Packet Dissections -> As Plain Text File
Select the packet range you want to see in your
If you are interested in the command line solution then you can check
I don't see any of the transmission modes for Ethernet or for IEEE 802.11 listed in the multimon-ng README file, so I'm not sure how you'd analyze a network capture, done at OSI layer 2, with multimon-ng.
I.e., I'm not sure that you could convert an arbitrary pcap file to something multimon-ng can analyze. If there's some protocol in the pcap file that contains waveforms of radio signals, there might be a way to dump the waveforms into a file that could then be analyzed by multimon-ng, but you can't, for example, turn an 802.11 capture into a radio waveform for the underlying 802.11 PHY - the analog radio signal has long since been turned into a bit stream and further processed by the 802.11 adapter, removing information at that layer.
