Hello , I am sniffing packets and my nic is on monitor mode, the DLT type i get from pcap is 127 which is RADIOTAP header...
from what i understood byte 3 on the header contains the length of the radiotap information preceding the 802.11 frame, and 2 bytes prior to byte 3 should be set to 0 , ( version, and pad ). is there anything i get which precedes the radiotap header ? or the radiotap header is the very begining of the packet i am sniffing ? the reason i ask is because when i am trying to look for the length of the radiotap header , and the version i get values that makes no sense... anyone ? thanks , E.h - This is the tcpdump-workers list.
