Hello, I'm working with some code (snippet below) that fails with libnet_get_hwaddr() function (it returns false). The code works fine under 7.x but not with 8.0 . Any thoughts as to what might be going on? Thanks much, Charles int get_hw_addr(char *device, u_char mac[6]) { struct libnet_ether_addr *mac_address; libnet_t *ln; char err_buf[LIBNET_ERRBUF_SIZE]; ln = libnet_init(LIBNET_LINK, device, err_buf); if (!ln) { fprintf(stderr, "libnet_open_link_interface: %s\n", err_buf); return -1; } mac_address = libnet_get_hwaddr(ln); if (!mac_address) { fprintf(stderr, "libnet_get_hwaddr: %s\n", err_buf); return -1; } memcpy(mac, mac_address->ether_addr_octet, 6); return 0; } -- Charles Owens Great Bay Software, Inc.
