    I’ve got thin (S30) and fat clients on the same subnets and need to use PXE to image both devices – but herein lies the problem. The Wyse Device Manger and RADIA (HP Openview imaging system) both use PXE and conflict with one another. I know WDM will only image the Wyse clients via the MAC address 00:80:64 but RADIA is not so discerning. On switching on the S30 it picks up the RADIA PXE and attempts to put down the FAT client image! Arghhhh ‘8O’

    I’ve tried filtering the RADIA PXE config file based on the architecture type (X86 PC) but it looks like WYse use the same architecture type, so no joy there so far, unless this if a custom type field on the Wyse that I can change?

    If so could then try to put the Wyse boot loader onot RADIA to redirect it to WDM. Help.

    Any thoughts gratefully received! Thanks…

    Hi Spot,

    HP OpenView I belive has a MAC filter that you can set it not to respond to certain clients. I would use this to to exclude any 00 80 64* requests. The other option is to more to FTP imaging of the CE devices and not use PXE at all.

    Maybe someone can post the exact steps to set up OpenView for you,

    Cheers,

    Thanks – trouble is its not HP Openview, its one of the Openview platforms components, RADIA, which is the problem as this does not provide an exclusion capability.

    Wyse FTP is too limited for our requirements.

    Do you know of any third party products that intermediate PXE requests and forward to the appropriate client?[/i]

    Hi,

    What you need to do is set up a firewall or ban on all incoming DHCP requests from 00 80 64* – What platfrom is the PXE server on?

    Because its a UDP DHCP braodcast the blocking service has to be on the RADIA box. 3COM made a DHCP proxy service that did this and there are others on the net to do the same.

    As for ftp upgrades this is more flexiable than PXE. Bundle the image in Rapport and then send it down. Other option is get the primer image and bundle up the extras.

    Thanks for the feedback. Think I’m going to try the FTP route, though I understand you lose reboot and WOL functionality. Is this just from within WDM – can I use other software to reboot / WOL the CE terminals?

    Hi,

    No, WOL and reboot will still work with the ftp method (you still use Rapport to deliver images). You have all the same functionallity as with the PXE method but none of the issues with PXE conflicts.

    Good luck!

    Cheers,

    Long live FTP! As you say, forget PXE – FTP works a treat.

    Thanks for your thoughts/advice.
