That means that every host on the "10.0.2.0/23" network is able to
NFS-mount everything under /opt/ltsp (including mounting /opt/ltsp/i386
as a root-filesystem). There is no netgroup magick included there, only

here the netgroup magick is in effect.

It's not possible to log in as root on a diskless workstation, because
the root account has no password set.

Maybe nscd was playing you a trick there, I'm not sure.
There is a script in lwat that creates the homedir, but maybe nscd is
caching the netgroup information that told your server that your
workstation was not oin the workstation-group.

I would have taken a look at the nic of the desktop.

To bind workstation to a hostname/ip-address, you have to edit
/etc/dhcp3/dhcpd.conf for now. In a future version of debian-edu (and
maybe lwat), there maybe some dhcp-server that gets the mac-address to
ip-address mapping from the ldap-server.

How did you try to do this. To me, it looks like you had only one
network where you can boot the diskless clients. did you change eth0 on
your "server" to be 192.168.0.254" ?

It looks like you changed the ip-adress of the server, without updating
dns and other services accordingly.
