Hi Larry. sudo tcpdump -ni any -c 1000 -w <filename>.pcap port 5353 For <filename> I usually include the date, hostname and some other meaningful stuff to help you remember what it was for in 6 months' time. Whilst this is running, make some queries in another terminal window.
I hope this helps. Cheers, Greg On Mon, 27 Jun 2022 at 14:11, Larry Stone <lston...@stonejongleux.com> wrote: > Petr, you are going to have to tell me how to create an appropriate PCAP > file.
