Default LTSP boots to log on but unable to authenticate.

I've been a lurker on this list for years and finally have a question.* I run three K12LTSP EL5 servers for about 110 low-end clients.* One of my current servers is giving hd errors and I'll need to change out the drive in the next month.* I've been watching the development of Ubuntu ltsp through this list for years and figured I'ld give 9.04 and 9.10 ltsp a shot.


I followed a simple how-to and have clients booting to the logon using a Virtualbox 9.10 LTSP sandbox with a bridged adapter.* (The same setup works fine using the identical virtualbox network sandbox configs for K12ltsp...)


On the Ubuntu 9.04 or 9.10 (I just did an upgrade) ltsp sandbox though, the clients will boot to the log on screen then fail to authenticate a user.* It comes up with a "can't find server" error right on the log on screen, blanks out, then comes back to the log on screen.


Any ideas?

Thanks,* Jim

Well, there is just three commands to use in almost any case.

ltsp-update-kernels
ltsp-update-sshkeys
ltsp-update-image

If those commands does not help you, very brutal way is re-build chroot
- if there is something very badly broken in chroot.

ltsp-build-client --arch i386

Maybe you need this one, because you upgrade whole distro. I usually do
clean and fresh installation in almost every case (/home is somewhere
away...).

I just installed Edubuntu DVD 9.10 in KVM virtual machine. Thin client
is Asus Eee 701. I needed this one for Asus Eee, then it booted.

I have enabled root in chroot and dist-upgraded chroot, too. And
installed mc, htop and ssh packages in chroot in testing purposes.

Thin client works very well to me.

And I can dive in chroot.

Please, we have very large collection of howtos - use them.
