Thanks for the answer.
Yes, I'm working as root but I'm still unable to find a solution to my problem. Unfortunately I've to implement this blessed ping function in C++ inside my cocoa app. I've used the following code without any results:
struct hostent *hp = 0;
struct sockaddr_in dest;
int sockIcmp = socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP);
hp = gethostbyname("10.63.10.70");
memcpy(&(dest.sin_addr),hp->h_addr,hp->h_length);
dest.sin_family = AF_INET;
int bwrote = sendto(sockIcmp,buf_out,buf_out_size, (sockaddr*)&dest, sizeof(dest));
To open the socket I'd to substitute the SOCK_RAW with SOCK_DGRAM. In this way the socket is succesfully open, but the function sendto returns always -1.
Is there some other way to implement a ping function in C++ working on Mac OS X? (this code, in Linux works fine).
Thanks in advance for any idea.
Luca
