Wireshark · Ethereal-users: [Ethereal-users] capturing whole packet

[Martin Shurbanov <shurbanm@xxxxxxxxxxxxxxxxxx>]

I am trying to figure out how I need to set tethereal to capture the data 
portion of the packet instead of just the header.
This is what I am using as a syntax:

tethereal -i eth0 -f "ip host 1.1.1.1"" 

Any help would be much appreciated.
