Even IPMI requires initially configuring the machine. Note that Wake-On-LAN is not part of the solution. A NIC in WOL mode will only scan received packets, and it usually does this at 10baseT to reduce power usage generating link beat. -- Donald Becker becker at scyld.com Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Second Generation Beowulf Clusters Annapolis MD 21403 410-990-9993
