In short, the authentication process for IPMI 2.0 mandates that the server send a salted SHA1 or MD5 hash of the requested user's password to the client, prior to the client authenticating.

ja cool, aber was ist mit RAID Controllern?...[d|device <path to device being checked>] Specify the device being monitored. If multiple devices should be checked provide the 'd' option multiple times. E.g. 'd /dev/sda d /dev/sdb' For devices behind LSI RAID controllers specify 'megaraid' and then the device number, e.g. 'd megaraid6'. Use storcli to find out the corresponding device numbers. For devices behind Adaptec RAID controllers specify '/dev/sg<X>' where <X> is the number for your device. Use e.g. sg_scan to find the device. You must also use 'O sat' or 'O scsi' according to the device interface. This are extra options only necessary for '/dev/sg<X>' devices....

„es ist jene Drehzahl, mit der der Lüfter-Algorithmus versucht den Lüfter zu betreiben.“
