[Ethereal-users] tethereal time filterng?request

["Bedri EROL" <bedri@xxxxxxxxxxxxxxxxx>]

I want tethereal to read the packages on the cable in a determined time interval. Can I do that by a type of filtering? I want to use tethereal for network analyzer. For example it'll give me the packet count in a hour on the cable. Of course I'll execute tethereal by other c progam that I would write? Your suggstions will help me also. Thanks
