Hi All,

I am attempting to setup an Edubuntu 8.04.1 LTSP test environment on our
network that already contains a DNS server run by our parent company
that we have no control over.

The initial test client which is specified by MAC address in the
dhcpd.conf file gets and IP address initially from the LTSP server,
boots pxelinux, and then does another DHCP request this time taking a
response from the corporate DHCP server which causes the client to not
boot Edubuntu (boots to Busy Box).

Based on man dhclient.conf, I can add commands to ignore the corporate
DHCP server, but I'm assuming I'd have to rebuild the client image for
the client to use this file.
Is there a way to include the same
configuration info in lts.conf?

You talked about DNS and DHCP, these are two different network services, and i'm sure DNS has nothing to do with LTSP thin client booting, so, configure your system following the instructions on the edubuntu wiki. There are two types of installations, ltsp-server-standalone and another, depending on whether there's an external DHCP server or if LTSP server is also the DHCP server.

In any case, you may need to issue:
sudo* ltsp-update-sshkeys
sudo ltsp-update-image
on the ltsp server if you are receiving initramfs or busybox on the clients.


Thanks for your help on this.

Regards,

Tim Boyden

Additional info...

Attempted to add network configuration to
dhclient.conf and rebuild
client image. Client still boots to Busy Box. So apparently that's not
the network configuration used by the client during the initial boot.

The client so far loads pxelinux.cfg/default, then loads vmlinuz, then
initrd.img, says ready, then Loading, please wait and does another DHCP
request. What file controls the network settings for this DHCP request
by the client at this point in the boot process?

Thanks,

Tim

Dave,

That was a typo; it should have said “…network that already
contains a DHCP server run by our parent company…”


*


I
have already run those commands you mentioned and configured the dhcpd file
according to the Wiki article. No go.

Hi All,



I am attempting to setup an Edubuntu 8.04.1 LTSP test environment on our

network that already contains a DNS server run by our parent company

that we have no control over.



The initial test client which is specified by MAC address in the

dhcpd.conf file gets and IP address initially from the LTSP server,

boots pxelinux, and then does another DHCP request this time taking a

response from the corporate DHCP server which causes the client to not

boot Edubuntu (boots to Busy Box).



Based on man dhclient.conf, I can add commands to ignore the corporate

DHCP server, but I'm assuming I'd have to rebuild the client image for

the client to use this file. Is there a way to include the same

configuration info in lts.conf?



You talked about DNS and DHCP, these are two
different network services, and i'm sure DNS has nothing to do with LTSP thin
client booting, so, configure your system following the instructions on the
edubuntu wiki. There are two types of installations, ltsp-server-standalone and
