I upgraded my iputils (from the Fedora Core 4 source RPM, iputils-20020927-22). The new version doesn't work. But, instead of arping returning -1 responses, it reports 0 responses, so at least ifup works without complaining about the address already being in use. However, if the address really is in use, it doesn't catch it. -- Bill Jordan SilverStorm Technologies _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
