Hi Michael. This is fantastic news to hear!
Will it eventually support non-Ethernet, and mixed link types in the same file (e.g. mmapped Linux USB and Ethernet), out of interest?
Yes, it should be possible to capture from multiple interfaces of link types which are supported today (so I do not add new link types). For supporting multiple link types, I had to add pcapng support, which is already there...

Best regards
Michael



Thanks,
Tyson.

Currently you can capture only on one interface, so
dumpcap -n -i en0
should work.
A future version will support
dumpcap -n -i en0 -s 100 -i en1 -s 1000
and so one, where you capture on en0 with snaplen 100 and on en1 with
snaplen 1000.
You will also be able to set a pe interface capture filter, link type,
promiscuous flag.
I'll send a note to the dev list, when this stuff is working.

Which platform are you using?

Best regards
Michael
