Hmm, wouldn't using "any" was a means of nullifying other interfaces break concurrent capturing on both the "any interface" and Bluetooth or USB interfaces?
As said in the other mail: -i all -i lo0 would capture packets on lo0 twice. I don't want to do some magic on command line args... Best regards Michael
Still, I agree with Chris's suggestions, with regards to weak emulation of an "any interface" under Windows; and "speculative capturing" (i.e. waiting for a device to appear before capturing relevant traffic). I'm liking the feature so far otherwise, though. (It means that I no longer have to launch Wireshark or TShark *8* times, and dismiss a tonne of warning dialogues just to do USB capturing). Thanks, and keep up the good work! Tyson.

It is simple to add -n and -t if you are specifying more than one interface (actually this is what tshark and wireshark do). I wanted to be explicit since I consider it currently an experimental feature. But, if the groups prefers, we can add -n and -t if there is more than one interface specified.To me, if it doesn't work without -n and -t, then it makes it that much more user-friendly to automatically use pcapng and threads whenever multiple interfaces are specified. I understand this is still a work in progress, but something else I was thinking about was the "-i any" interface. What will happen if someone specifies something like, "-i eth0 -i any -i lo" or variations thereof? I assume it would be treated as "-i any" only? And speaking of "-i any", obviously on Windows, that isn't supported ... but a neat thing would be if it could be by internally scanning all interfaces and treating it as if "-i 1 -i 2 ... -i n" were specified. And while I'm at it ... another feature that I think would be nice to have would be to be able to specify capturing on an interface that doesn't yet exist, such as ppp0. For my USB/PPP capturing, currently to get a capture of all traffic over that interface, I either have to use usbmon or ppp's record option to generate a pppdump file. (OK, this last one isn't really specific to capturing on multiple interfaces, but it's related to capturing so ...)Thanks for the feedback.You're welcome ... thanks for the feature! - Chris ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe -- Fight Internet Censorship! http://www.eff.org http://vmlemon.wordpress.com | Twitter/FriendFeed/Skype: vmlemon | 00447934365844 ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
