Dear All
I used a SOCK_RAW and IPPROTO_TCP and set the IPHDRINCL option for that
socket.
If we put the th_sum to 0 , does the kernel , itself , comput the tcp sum or
not ?
how can i make the kernel compute the cksum of the TCPHDR ?
By the way , i want to know if there is any library to compute a ip_cksum
and tcp_cksum of a buffer of a TCP/IP packet ?
THANX
