Except Beej's guide has nothing to do with RAW sockets. And if the guy who asked hasn't found the answer in the last year since he posted, then I think it's too little too lateOriginally Posted by jeffcobb
bit∙hub [bit-huhb] n. A source and destination for information.
Here is the workaround how to get source ip. (It is adopted part from iputils)
Code:int probe_fd = socket(AF_INET,SOCK_DGRAM,0); struct sockaddr_in dst; dst.sin_family = AF_INET; connect(probe_fd, (struct sockaddr*)&dst, sizeof(dst)); socklen_t alen = sizeof(dst); getsockname(probe_fd, (struct sockaddr*)&dst, &alen); close(probe_fd); printf("Source: %s\n",inet_ntoa(dst.sin_addr));
