The one that writes seems to be working fine (I can see the packet in Wireshark) but the reading does not work; it just keeps waiting. Can anyone help me to find out the problem? Here is the code. Thanks, Daniel Writing program (works fine): main() { int fd; int result, write; struct ndrv_protocol_desc prot_desc; struct ndrv_demux_desc demux_desc[1]; struct sockaddr_ndrv ndrv; u_int8_t packet[1000]; //Open socket fd = socket(PF_NDRV, SOCK_RAW, 0); //error handing //Bind to interface en1 strlcpy((char*)ndrv.snd_name, "en1", sizeof(ndrv.snd_name)); ndrv.snd_len = sizeof(ndrv); ndrv.snd_family = AF_NDRV; bind(fd, (struct sockaddr*)&ndrv, sizeof(ndrv)); //error handing //Build packet memset(&packet, 0, sizeof(packet)); //Destination MAC address - here goes my en1 MAC address packet[0] = 0x00; packet[1] = 0x21; packet[2] = 0x41; packet[3] = 0x21; packet[4] = 0x11; packet[5] = 0x31; //Source MAC address - fictitious MAC address packet[6] = 0x12; packet[7] = 0x23; packet[8] = 0x34; packet[9] = 0x45; packet[10] = 0x56; packet[11] = 0x67; //Set packet type - this is the type field in the frame; no specific reason for this number but I think must match the demux descriptor in the reading program. packet[12] = 0x0f; packet[13] = 0x0f; //Some Data strcpy((char*)&packet[14], "ABCDEFGHIJKLMNOPQRSTUVWXZ1234567890 This is a test \0"); //Send packet write = sendto(fd, &packet, 1014, 0, (struct sockaddr*)&ndrv, sizeof(ndrv)); //error handling close(fd); return; } Reading program (not working, it keeps waiting for packet): main() { int fd; int read; struct ndrv_protocol_desc prot_desc; struct ndrv_demux_desc demux_desc[1]; struct sockaddr_ndrv ndrv; u_int8_t buffer[1000]; //Open socket fd = socket(PF_NDRV, SOCK_RAW, 0); //error handing //Bind to interface en1 ndrv.snd_len = sizeof(ndrv); ndrv.snd_family = AF_NDRV; strlcpy((char*)ndrv.snd_name, "en1", sizeof(ndrv.snd_name)); bind(fd, (struct sockaddr*)&ndrv, sizeof(ndrv)); //error handing //Define protocol prot_desc.version = (u_int32_t)1; prot_desc.protocol_family = (u_int32_t)13458; //Just a number that do not match any other protocol defined in the interface prot_desc.demux_count = (u_int32_t)1; prot_desc.demux_list = (struct ndrv_demux_desc*)&demux_desc; //Define DEMUX demux_desc[0].type = NDRV_DEMUXTYPE_ETHERTYPE; demux_desc[0].length = 2; demux_desc[0].data.ether_type = htons(0x0f0f); //same as ethernet type in the writing program //Set protocol using socket options setsockopt(fd, SOL_NDRVPROTO, NDRV_SETDMXSPEC, (caddr_t)&prot_desc, sizeof(prot_desc)); //error handing //Receive packet read = recvfrom(fd, &buffer, sizeof(buffer), 0, NULL, NULL); //error handing close(fd); return; } _______________________________________________ Do not post admin requests to the list.

The header does not explain what options correspond to withAddress. I'm left to guess that I should use virtual memory, for example, as neither physical nor UPL seem to match. I would like a clarification, if possible. Thanks, Joel On Jan 27, 2011, at 2:26 PM, Shantonu Sen wrote: > command double-click on the symbol in Xcode. It will take you to the header.
