And presumably you're not doing that in immediate mode. (tcpdump *currently* uses immediate mode if it's in sniff-and-print mode, but maybe it should select a shorter timeout instead - and perhaps, these days, a 1-second timeout is too much even if you're capturing to a file.)
The protocol idea is new to me.
And that's where I'm saying we might want to use non-memory-mapped capturing. _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
