I am sending three types of packets on another machine in LAN using SENDIP tool I have specified min. length = 8 bytes and max.length = 512 bytes...
but....
when I send udp packets (min. length) and capture using tcpdump it shows pointer length=70 bytes.
when I send udp packets (min. length) tcpdump shows pointer length=574 bytes.
when I send icmp packets (min length),tcpdump shows length of first two packets as 80 and length of rest all packets as 66 bytes.
The pointer length I am getting through tcpdump is by using header information specified in the packet....
Why there is discrepancy between the results of sendip and tcpdump ???
