Re: [K12OSN] is it possible to use Windows DHCP server with LTSP?



John,

Here's my config from Windows 2003 R2 DHCP: (which hands out pxe
successfully).  You have to tweak the bootfile parameter for etherboot
systems.  I used it to hand out DHCP across multiple subnets, our
central router does a DHCP/BOOTP relay to the IP address of the dhcp
server.

Global Options:
Option Name	Vendor	Value	Class
006 DNS Servers	Standard	10.142.1.7, 10.142.1.11	None
015 DNS Domain Name	Standard	hhp.hhprep.org	None
017 Root Path	Standard	192.168.0.5:/opt/ltsp/i386	None
044 WINS/NBNS Servers	Standard	10.142.1.7, 10.142.1.11	None
046 WINS/NBT Node Type	Standard	0x8	None
066 Boot Server Host Name	Standard	discovery.media.local
None
067 Bootfile Name	Standard	/lts/pxe/pxelinux.0	None


You really don't need to worry about the WINS stuff.  Also, I'm
transitioning my domains, so I have some stuff on the old "MEDIA.LOCAL",
and some on the new "HHP.HHPREP.ORG" so it looks a little wonky.

Within each subnet config, I add the default gateway/router.  That's it.
Remember, this config is for PXE bootable images.  Change the Bootfile
name to the Etherboot one if you need that as the default.  Windows DHCP
doesn't do the nice if/else selection of Bootfiles.... I personally am
going to redo all my thin-client hd installs and setup those etherboot
images to boot PXE.

Hope this helps.

Hi Chuck,

A couple of questions:

1) Do I need option 12, the netvista option, if I am not using
netvistas? Is
this a generic netboot parameter?

2) If windows pads the root path with 000 do I need a symlink on my
linux
server from a directory called /opt/ltsp/i386000 > /opt/ltsp/i386

3) is the string for option 211 always tftp?

4) I glibly said I had the other boot parameters (ip, subnet mask,
gateway)
correctly set, because those parameters are the defaults handed over by
the
dhcp server on that scope. As I think about it I think I should be using
an
ip, subnet mask, and gateway consistent with that of the ltsp server
(which
sits on a different subnet than my test client. So if my LTSP server is
10.114.0.105/16 my clients should be 10.114.0.x/16 and use 10.114.0.105
as
the gateway. Err, but perhaps I am getting myself in a muddle here.

Thanks again.

John
