Is it possible to serve both i386 and ppc from the same ltsp server? I'm using edubuntu and want to bring the PPC's into the picture also.
11:25
<wizzy>
jgedeon: You would need to differentiate them at boot time. If you are using PXE you could drop a file named by the MAC address into the pxelinux.cfg/ directory
11:29
<vagrantc>
jgedeon: you'd also need to build the ltsp environment on a machine of the appropriate architecture. i.e. if your server was i386, you would have to build the PPC environment on a PPC machine and copy it over to the i386 server.

LTSP chroot bug at https://launchpad.net/distros/ubuntu/+source/portmap/+bug/61668 is affecting my Edubuntu 6.06 install as I am unable to do that install how to clear that bug from the ISO and start installing?  
11:46
<jgedeon>
vagrantc: after it was copied over it could then be administered by the same server which would be x86?
11:47Egyptian[Home] has joined #ltsp
11:47gigabytes has joined #ltsp
11:49
<wizzy>
jgedeon: yes. Hmm - you would also need to set the nfs root to an architecture-specific path - basically dhcpd.conf has to list all the PCs
11:50
<jammcq>
wizzy: not entirely true
11:50
dhcpd.conf can have a conditional that tests the vendor string, which it can use to determine if it was a i386 or a ppc client connecting
11:50
<jgedeon>
wizzy: Correct, that is the way that we are doing it now. But they have asked if it's possible to bring the PPC's into the picture. And I have read that is was both possible and not possible. So I am a bit confused on getting it.
11:51
<wizzy>
jgedeon: there is no reason it cannot be done.
11:51
<jammcq>
it's possible to "serve" multiple architectures from the same server
11:51
but currently, there's no way to "install" the multiple architectures
11:51
<jgedeon>
Gee you didn't need to say that. Now I will have to research and figure it out. LOL
11:51
<wizzy>
jammcq: Can you test for PXE *and* arch. at the same time ?
11:52
<jammcq>
wizzy: 2 separate tests
11:53
<wizzy>
Can you use ltsp-build-client to install a foreign architecture ? Or must it be built on a home architecture?
11:53
<jgedeon>
I think it is something like if substring(option vendor-class-identifier, 0, 9 ) = "PXE { filename "/ltsp/i386/pxelinux.0"} else ......
11:53
wizzy not sure that is what I will have to research.
11:54
<jammcq>
http://wiki.ltsp.org/twiki/bin/view/Ltsp/DHCP#Automatically_using_the_correct
11:54
wizzy: you need to run ltsp-build-client on the correct architecture
11:54
if you want a ppc client, you need to run ltsp-build-client on a ppc server
11:55
then, once that's done, you can transfer the result to a x86 server
11:55
<jgedeon>
Build it on a ppc server then copy it over?
11:55
OK.
11:55
<wizzy>
copy over /opt/ltsp/ppc/*
11:55
<jammcq>
zackly
11:55
<wizzy>
and the kernel
11:55
<jgedeon>
I have a feeling this sounds easier than it is. LOL
11:56
<wizzy>
and (easiest ....) list all your clients .
11:56cstextiles has left #ltsp
11:56
<jammcq>
well, if you have a ppc server, it's not that hard
11:56
<jgedeon>
LOL I will have to sneak one from the school after Christmas break
11:56
<wizzy>
Anyone managed to serve dhcp out of LDAP ?
11:57
<jammcq>
hmm, never heard of doing that
11:57
<jgedeon>
I'm not sure why you would want to do that?
12:00
<wizzy>
I want to have all my configuration data in LDAP - users and computers.
12:00
DNS served out of LDAP too.
12:02
We want to roll out a number of remote labs - probably fat diskless - and I want to be able to track computer usage, see if clients go down, etc.
12:02
<jgedeon>
wizzy: why not have your DHCP server authenticate to the LDAP?
12:03
<wizzy>
It is not about authentication
12:03
I want to list MAC addresses, IP addresses, kernels, root paths in LDAP
12:04
<jgedeon>
Oh ok.
12:08
jammcq: do you know where or what to search for documentation on what I need to do, what I am searching isn't giving too much.

<wizzy>
jgedeon: I would install PPC edubuntu on a PPC server, copy over the /opt/ltsp/ppc tree and kernel, and then trash the PPC install
12:11
<jammcq>
jgedeon: to do what?
12:11
<jgedeon>
wizzy: is it really that easy?
12:12
<wizzy>
Are you using edubuntu ? or K12LTSP ?
12:12
<jgedeon>
edubuntu is the preferred.
12:12
<jammcq>
k12ltsp already supports ppc on a x86 server
12:12
<wizzy>
edubuntu has a weird login setup
12:13
<jammcq>
edubuntu uses ldm, which is just a python gui wrapper around ssh
12:13
<wizzy>
What is your (i386) server running ?
12:13
<jgedeon>
Edubuntu
12:13
<wizzy>
then install edubuntu on a PPC, as I said
12:14
it is that easy - besides setting up dhcpd.conf
12:14
<jammcq>
yes, that's all there is to it
12:15
<jgedeon>
Boy do I feel like a heel... I think I was refusing to think it was just that easy. LOL

Does anyone know how to get the dhcp server to call a script whenever it sees a DHCPDISCOVER ?
