Hello everybody!

I'm trying to filter a pcap file using the following command and filter:

tshark -q -r capture.pcap -z io,stat,0,eth.addr==aa:bb:cc:dd:ee:ff

But I'm getting this error:

tshark: invalid "-z io,stat,<interval>[,<filter>][,<filter>]..." argument

Does anyone know what I'm doing wrong? Whether I use an ip filter (e.g. ip.addr== the result is ok.

Works for me, what version of tshark and what shell are you running this in?

Hi grahamb, thanks for your quickly answer. I'm using terminator as shell and the version is "TShark (Wireshark) 2.2.2". I tried in a different PC and it worked, I'm wondering if it could be some library version. Any idea?

Did you use the same shell on the other PC? I'm clutching at straws that it's an argument escaping error.

(05 Dec '16, 11:03) grahamb ♦

Yes, I used and I also tried a different shell, same thing.

Do you know what library is responsible to parse the eth parameters?

I tried in a different PC and it works ok. Thanks for your time grahamb!!
