C Socket Program

Hi I am working on Small? C Socket Program IN LINUX which by using custom headers can cause apche server to crash. I have written the C code and its almost complete.I have a problem in Calculating the CRC . The problem exists in checksum.c file in which? i am not able to compute. correct tcp checksum fields? Calculated checksum and correct checksum can be viewed in wireshark packet sniffer or any other. ? I am attaching the C Program with Headers. I will award the bid to who so ever can get the correct crc. Regards Rajesh Kulkarni ## Deliverables stdio.h , stdlib.h , string.h, stdlib.h, math.h are not included due to availability
