Hi, I made some mistakes in my prevous mail: <I guess that in your case when you have IEE 802.11 headers you maybe have to use a filter such as <ether[0] & 0xF0 = 0x8
I guess that in your case when you have IEE 802.11 headers you maybe have to use a filter such as ether[0] & 0xF0 = 0x80 <You could for example start with capture all packets matching a certain capture filter and save the result to a file <tethereal -i eth2 -f 'ether[0] & 0xF0' -w file1.pcap You could for example start with capture all packets matching a certain capture filter and save the result to a file tethereal -i eth2 -f 'ether[0] & 0xF0 = 0x80' -w file1.pcap
