Hi all.I'm porting a Linux project (using sockets to implement a ping function) on Mac OS X. My problem is that the function:int sock_icmp = socket(AF_INET, SOCK_RAW, IPPROTO_ICMP); returns always -1.Where is my mistake? For me is the very first time using socket on Mac.Thanks in advance for any idea.
Hi Luca,This isn't really a Cocoa question... you would probably get faster/ more responses for these kinds of questions on the Darwin-dev mailing list... but, you should do something like this (at least to debug):
int sock_icmp;
if( (sock_icmp = socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)) == -1 ) {
fprintf(stderr, " --> Error opening socket: %s\n", strerror(errno));
return -1;
}
However, your problem most likely is EACCES... in darwin, SOCK_RAW
requires root privileges to open.
