Live OS Network Boot through Wi-Fi
Project ID:
543949Project Type:
FixedBudget:
$250-$750 USD
Project Description:
We using debian-live (http://debian-live.alioth.debian.org/) - based thin client OS in our network, and we need to have ability of booting our clients though Wi-Fi instead of booting through wired LAN (like we have now). After some research we decided to create small initrd which can connect to Wi-Fi access point and mount remote folder for boot from it. Debian-live build already include initrd which can mount remote folder through wired LAN with NFS protocol.Probably, client should boot from cd or pendrive first, and then boot initrd OS with Wi-Fi support, then connect to Wi-Fi access point and mount remote folder for boot actual live OS from this folder.

Hello. Find details in PMB, please. Thank you.
I have done lots of work on Wifi specifically Linux wifi drivers and I can provide one simpliest solution to boot the Live OS thorugh WIFI having single server connected to the access point.
Very interesting project.I have implemented Wi-fi in matlab and one year experience of Linux.I have implemented different server client model in linux..I love to do this project
I've done this exact thing before over LAN.
You need to use gPXE (formerly etherboot) which will allow you to specify a live CD image to boot over the network. Quite nifty actually.

I've done this exact thing before over LAN.
You need to use gPXE (formerly etherboot) which will allow you to specify a live CD image to boot over the network. Quite nifty actually.
HOWEVER your biggest constraint will be wireless card support in gPXE. There isn't a single wireless chipset I'm aware of that supports PXE boot natively. These are the only two wireless chipsets gPXE supports:
1. Realtek 8180/8185 (supported in Linux by the rtl8180 driver; the 8180 is 802.11b-only, the 8185 is 802.11b/g)
2. All Atheros cards that do not support 802.11n (supported in Linux by the ath5k driver)
Yes you can create a bootable CD that will support netbooting with any wireless or wired card gPXE supports - but, again, you're pretty constrained on the wireless side.
You're out of luck if you want netboot capability with widely popular Intel and Broadcom 802.11 chipsets.
Also be aware even if you get this to work booting a 600-700MB live CD image over wireless will be quite slow, even with great connectivity to your AP. I would keep your ISO boot images to 100-200MB tops otherwise anyone booting will have to go get a cup of coffee and take a nap by the time it's done. The best bet for speed is to boot the kernel and initrd images directly over the network rather than an ISO image - and please also note there is no such thing as generic ISO image boot over the network (i.e., booting just any ISO image over the network, be it LAN or wireless). There are some hoops that have to be jumped through to get that to work even with gPXE for some Linux distributions (Knoppix, Debian, Fedora, etc).
Anyway, if you think the wireless card support constraints won't be an issue then I can work on it - otherwise anyone else would be spinning their wheels on this. Other "solutions" - NFS booting, for example - simply won't work unless you can get an emulated PXE layer (i.e., gPXE/Etherboot) in there. less
