I also stumbled upon the problem mentioned in the older post and I'd like to confirm that the patch from http://www.mail-archive.com/ecos-discuss@ecos.sourceware.org/msg09992.html seems to really help. Using this and setting the default route to my interface (code borrowed from the ppp) static int setDefaultRoute(u_int32_t g, int cmd) { static int rtm_seq; int routes; struct { struct rt_msghdr hdr; struct sockaddr_in dst; struct sockaddr_in gway; struct sockaddr_in mask; } rtmsg; if ((routes = socket(PF_ROUTE, SOCK_RAW, AF_INET)) < 0) { diag_printf("Couldn't %s default route: socket: %d\n", cmd=='s'? "add": "delete",errno); return 0; } memset(&rtmsg, 0, sizeof(rtmsg)); rtmsg.hdr.rtm_type = cmd == 's'? RTM_ADD: RTM_DELETE; rtmsg.hdr.rtm_flags = RTF_UP | RTF_GATEWAY | RTF_STATIC; rtmsg.hdr.rtm_version = RTM_VERSION; rtmsg.hdr.rtm_seq = ++rtm_seq; rtmsg.hdr.rtm_addrs = RTA_DST | RTA_GATEWAY | RTA_NETMASK; rtmsg.dst.sin_len = sizeof(rtmsg.dst); rtmsg.dst.sin_family = AF_INET; rtmsg.gway.sin_len = sizeof(rtmsg.gway); rtmsg.gway.sin_family = AF_INET; rtmsg.gway.sin_addr.s_addr = g; rtmsg.mask.sin_len = sizeof(rtmsg.dst); rtmsg.mask.sin_family = AF_INET; rtmsg.hdr.rtm_msglen = sizeof(rtmsg); if (write(routes, &rtmsg, sizeof(rtmsg)) < 0) { diag_printf("Couldn't %s default route: %d\n", cmd=='s'? "add": "delete",errno); close(routes); return 0; } close(routes); return 1; } I am able to send the broadcasts as I intended. I'd vote for the inclusion of the option in the main tree.
