Hi,
I am working with raw sockets on freeBsd3.4.
I am creating my own IP & TCP header & want to pass it
along with the packet.
I tried setting up IP_HDRINCL option but it gives me
error in sendto function as "sendto: Invalid argument"
I am using following statement
if(setsockopt(sockd,IPPROTO_IP,IP_HDRINCL,(char
*)&on,sizeof(on)) < 0) {
perror("setsockopt");
exit(1);
}
where int on=1;
I am not able to see required data in IP header as it
is not using this option and generating its own ip
header.
I donno why I am not able to set the IP_HDRINCL
option.
If anyone can help me on this it will be great help.
Thank you.

P.S: I am not on mailing list so if u can please reply
me via e mail , I will be highly obliged.
