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? -- Roger Oberholtzer OPQ Systems AB Ramböll Sverige AB Kapellgränd 7 P.O. Box 4205 SE-102 65 Stockholm, Sweden Tel: Int +46 8-615 60 20 Fax: Int +46 8-31 42 23
You set up the machine to boot from harddisk first and then lan. So initially it will not have an mbr and install from lan. Afterwards it will pick up the harddisk installation. If you need to reinstall just(!) wipe the MBR: dd of=/dev/sda if=/dev/zero bs=1024 count=1 (no guarantees on that one - don't complain if you wipe your whole disk) Roger Oberholtzer wrote:

The trick you're looking for is in the pc's bios that you're going to install. For example ibm thinkcentre s50 desktop pcs know two boot orders: standard and automatic bootup. The automatic bootup order is used if the system has been woken up over lan. Else it uses standard boot order. regards Thomas -- 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 12:53:39:

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.

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

Small note: on my computers (Asus) this is a bios option. In the APM menu look for power-on from pci devices. I found that with this setting the ethernet activity led on the back never went off. (same for the lights on the switch)
