So if I'm right, there are only two possibilities to sniff ethercat:

1) trought a HUB (ethercat compliant)
2) run wireshark on the master

this scenario is not so nice ...
I immagine to be in the situation to solve a trouble when I'm in my 
customer's factory, I'll not have for shure my HUB with me, even more, 
if my master can't run a graphic interface I can't run wireshark on the 
master PC.
Is there any another solution ?
