E.g. either activate or deactivate DTR for 5+ seconds. ;) "Reboot" - Power-off: +dtr sleep 5 -dtr Power-on: +dtr -dtr This reminds me of the 'clapper' agent someone suggested awhile ago. -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
