My router provides a live capture in an fancy web interface full of authentication and JS stuff. So if I capture the traffic firefox download a pcap file til I stop the job. I want to be able to see all traffic on the fly, also not to wait for finish download/capture job. I know wireshark can read named pipes so the question is how to redirect a writing file into a named pipe. I do not find any solution how to force firefox to write into one, and curl is not an option cause JS and authentication.
