Modify client to do system inventory on PXE boot

[Bart Smit]

I’d like to adapt the FOG client to take an inventory automatically after PXE boot. I’ve unpacked the init.gz and had a look around, but I’m unsure of the next steps. What would be the best strategy to:

• run the DMI report
• run the partitions report for all local drives
• tarball/zip the results and FTP them

TIA for any pointers

Off the top of my head I’d suggest editing /etc/init.d/S99fog and adding a conditional statement like
[CODE]if [ “$mode” != “inventory” ]; then
sh /bin/fog.inventory;[/CODE]
before the rest of the $mode checks.

So…
[CODE]afterActionTerm=“reboot -f”;
if [ “$shutdown” = “on” ]
then
afterActionTerm=“poweroff”;
fi

if [ “$mode” == “debug” ]; then
[/CODE]

becomes…

[CODE]afterActionTerm=“reboot -f”;
if [ “$shutdown” = “on” ]
then
afterActionTerm=“poweroff”;
fi

if [ “$mode” != “inventory” ]; then
sh /bin/fog.inventory;

if [ “$mode” == “debug” ]; then
[/CODE]

Warning: That was off the top of my head and has not been tested.

Are you wanting to take an inventory every time the computer PXE boots?

@Bryce,

@Chad, yes indeed, basically I want to use the PXE image to get the hardware info and then change the host to point the client to an image based on that info.

I’ll have a look at the init.d scripts and update this thread

Thanks,

Bart…

Dude… That’s a top idea…

Please let me know if you have any success…

I too have heavily modified fog to do extra stuff, if only there was a way to combine all these customizations…

Right now, the inventory task ends with a clearing of the task file and a reboot. If you want to perform an inventory and then do more stuff, I think you’ll have to modify that behavior without interfering with the rest of the tasks that call the inventory scripts.
