It's not really a protocol nor is it a API like PXE is. It is just a ethernet paket that contains a "magic" start sequence, 16 times the Mac adress of the client to wake up and the paket is send to Mac Adress ff:ff:ff:ff:ff:ff -> ie broadcasted. The NIC hardware in the client is permanently powered on and looks at every packet that comes over the wire. If it finds the magic start sequence and its Mac Adress the computer is started. -- GLS IT Services Thomas Mieslinger GLS Germany Str. 1-7 fon: +49 6677 17 463 36286 Neuenstein fax: +49 6677 17 111 Germany eMail: thomas.mieslinger@gls-itservices.com Roger Oberholtzer <roger@opq.se> schrieb am 14.02.2006 15:28:03: the

Leave it to IBM. We are using SuperMicro. I will have to look a comparable setting. I am not sure all our SuperMicro MBs support wake-on-lan.
I thought wake-on-lan was some other protocol than PXE. Not exactly how that translates into a boot. But if it looked interesting, I could invest time in finding out. Perhaps it is mainly useful in selecting two different boot device lists as IBM have it.

Has anyone done a network install of SUSE when the client is started with wake-on-lan? Is this even possible?
The reason I ask is I am unsure how you disable a machine from being installed each time it boots. Do you have to turn on/off PXE (or whatever you're using) in the BIOS when you want to change behavior?
Or
modify the dhcp server's setup? I guess either would work. What are people doing in practice?
