Wireshark-users: Re: [Wireshark-users] Getting duration when using tshark -z conv
Unfortunately not, thanks.

When I get conversation breakdowns from wireshark it gives me these
columns:
Address A	Port A	Address B	Port B	Packets	Bytes	Packets
A->B	Bytes A->B	Packets A<-B	Bytes A<-B	Rel Start
Duration	bps A->B	bps A<-B
(saved as CSV from the conversations window)

But when I get conversations from tshark it only has these:
                                               |       <-      | |
->      | |     Total     |
                                               | Frames  Bytes | |
Frames  Bytes | | Frames  Bytes |
 
I really want the Duration data so that I can roughly tell the consumed
bandwidth of a given conversation.

With wireshark generating the conversation breakdown takes about 5 times
as long as with tshark, and with tshark taking over an hour that's a
significant difference :)
I can't even load the files on 32 bit Windows because it runs out of
address space, but tshark uses much less memory too.

What I'd like is for -z conv to give me exactly the same columns as
wireshark.

Thanks

Jim
