Hope this explanation saves you some time. You should find a username (USER) and password (PASS) followed by requests to retrieve (RETR) five Windows executable files: q.exe, w.exe, e.exe, r.exe, and t.exe. I didn't try to catch how this is currently handled by Scapy. Filter on to review the FTP commands as shown in Figure 14. Profishark: end of options ( 0x00 0x00 0x00 0x00) is left - if_tsresol is strippedīlock -> Link type / snap length (don't know if you'd like to interpret link type)Īdditionally, I'd like to mention that multiple interfaces with different if_tsresol can exist in a single PcapNG file. Wireshark: if_name option is corrupted - not catched, if_tsresol option follows later - interpreted block does not contain the first 8 octets (block type and block total length) and the last 4 octets (block total length)Īfterwards, options get set as options = block. The data passed as parameter block to function read_block_idb does not contain the complete IDB as shown above. 09 00 01 00 (Option Code = if_tsresol / Option Length = 1)Ġ9 00 00 00 (if_tsresol = 9, padded to 32 bits)Īs we can see, option if_tsresol is set by ProfiShark.
