Disabling IP Checksum Calculation
Hello Friends,
I'm constructing the IP Packets by using the RAW Sockets. If I give any value for VER/TTL/Protocol the packet is being transmitted with that particular values.
But in case of IP Checksum, I'm always getting the correct checksum value irrespective of the value I give.
Can anyone please let me know, who is filling the correct checksum and how to disable it??
Thanks in Advance.
Regards,
Aamir
