How to receive the datas?
Look:
the first I create socket sk:
sk=socket(AF_INET, SOCK_RAW, IPPROTO_RAW);
and I fill data into Ip Head and Icmp Head,
then I sendto the packet,but I don't receive
any datas:
lenrecv=recvfrom(sk,buf,100,0,(struct sockaddr*)&addr,&rlen);
my codes run at the function recvfrom,but it
couldn't return variable lenrecv,and it look like down,
I want to know why?how to receive the data?
(I couldn't creat socket like this:
sk=socket(AF_INET, SOCK_RAW, IPPROTO_ICMP);
I want to know when I creat socket like this
sk=socket(AF_INET, SOCK_RAW, IPPROTO_RAW);

Re: How to receive the datas?
leetow2003, is this a programming problem or a network problem? If this is a network problem, please give more information about your network setup. Thanks.
