Functional Principle of the Fogserver

[_Devilnoc]

Hello,

my first Entry. First to me, my name is Daniel, i’m 20 from Germany and i work as a computer scientist. Im starting to use Fogproject.
Now to my question. Can you tell me stept by step how fogserver works, if the client pulls an image?
I think this way:
(Task is already active)

1. Client is booting (NIC) (PXE)
2. Client got IP from DHCP
3. Fog detect MAC from Client and releases the active task
4. Small linux-client starts on client
5. Client communicate with Fogserver over NFS ?
6. Client got Image over (T)FTP
7. Complete

Is this the right explanation?
Tranks ahed!

No, it’s not correct…

1. Client is booting with PXE:
   1.1. bootp
   1.2. download kernel + initrd over tftpd
   1.3. booting kernel + initrd
2. kernel does dhcp request (no userspace dhcp!)
3. kernel starts init
4. init starts up services
5. init starts fog-script
6. fog-script collects some info and contacts server
7. fog-script run task according to info from server
   8a) unicast: image over nfs
   8b) multicast: image over udpcast
8. Client reports result to server and reboots
