Problem conclusion

  • See the following message in the udp packet for the TraceRoute
    ping:
    - [Expert Info (Error/Malformed): Bad length value 2048 > IP
    payload length]
    
    It is a big endian/little endian bug issue and is platform
    specific.
    We provide the correct packet length 8 bytes. However the hex 8
    bytes is reversed the order from 00 08 to 08 00.
    It is a big endian/little endian bug issue and is platform
    specific.
    Use htons(8) while adding the total length to the packet.
