Re: Problems with tshark displayfilters

Isn't the display filter set using -R option. I don't see that in your
command.

Hello !
So I want to use tshark (v 1.2.4) to get information out of the captures to
a txt file, afterwards I want to convert the txt to a csv and create
statistics out of it.
But when using tshark it seems to ignore all display filters I'm using.
Here is an example I've found:
"tshark.exe -q -z "io,stat,600, ,tcp.port == 80" -r DividedFile_1.pcap >>
stats.txt"
This should lead to a txt file containing:
===================================================================
IO Statistics
Interval: 600.000 secs
Column #0:
Column #1: tcp.port == 80
                  | Column #0    | Column #1
Time            |frames| bytes |frames| bytes
000.000-600.000 281214 128192886 51408 28494414
===================================================================
(I hope this is properly formatted now)
But in my case I only get the first column.

So I tried it with just one filter:
"tshark.exe -q -z "io,stat,600,tcp.port == 80" -r DividedFile_1.pcap >>
stats.txt"
===================================================================
IO Statistics
Interval: 600.000 secs
Column #0:
                 | Column #0
Time           |frames| bytes
000.000-600.000 281214 128192886
===================================================================
Same result with no filter option set, or like before with both filters on.
The same happens when using different filters like ip.addr (even if it's
not on the same subnet) or different ports.
Does anyone here have an answer explaining this behaviour or maybe a
complete different solution ?
Because I seem to be the only one having this problem I guess I'm doing
something wrong here.

Thanks in advance!

Sebastian
