What's the best what to test the status of an Ethernet interface programmatically? We've been using this code similar to this:
struct ifmediareq ifmr; memset(&ifmr, 0, sizeof(ifmr)); strcpy(ifmr.ifm_name, "nfe0"); ioctl(sockfd, SIOCGIFMEDIA, (caddr_t)&ifmr) and then checking the value of ifmr.ifm_status & IFM_ACTIVE. We've found that every once in a while this code will return a false positive, indicating that the interface has gone offline when in fact it has not. So, is there a more reliable call to test if an Ethernet interface has gone offline? _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
