Hi Gavin,
The DHCP problem is resolved, but i'm having BusyBox prompt on the thin clients instead of loading the splash and gdm. Please help me.

Hi Gavin,
Thanks so much. You know i actually decided to remove the other nic and have just one nic and could actully get the DHCP working, but then it get the point of loading the splash and gave me busy box, with "udevd-event[1443]: udev_rules_apply_format: unknown format variable '$:rvr1.0:cvnUknownChasisManufacture:ct3:cvrVersion1.00:'
BusyBox v1.1.3 (Debian 1:1.1.3-5ubuntu12) Built-in shell (ash) Enter 'help' for list of built-in command.
(initramfs)
I was only trying to run away from one problem , but ran into another.
Pls help.
David

can you reply with some extra information:
1. run "ps aux |grep dhcpd" and see if the dhcp server is running and on
? what interface, eg.
gavin at robin ~> ps aux |grep dhcpd
gavin? ? 19810? 0.0? 0.1? 3004? 764 pts/6? ? S+? 14:13? 0:00 grep dhcpd
dhcpd? ? 31979? 0.0? 0.0? 2872? 308 ?? ? ? ? Ss? Jul10? 0:02 /usr/sbin/dhcpd3 -q -pf /var/run/dhcp3-server/dhcpd.pid -cf /etc/ltsp/dhcpd.conf eth0
2. Run "/sbin/ifconfig" to check what ip addresses are on what interfaces.
3. The file /etc/ltsp/dhcpd.conf
If you give us the output of these three, we'll get some idea what your
problem is.

Hi all,
I have downloaded the desktop and add-on cd's. can someone help me
with an install model?
I have 10 x P4 2 Ghz 512 mb Ram 80GB hd? PC's in a small school lab +
2 more in the head teachers office. I want to expand 2 6 more for a
total of 18 units.
I want the kids to be able to log in from any machine in the lab
I want the teachers to be able to log in from any machine in the school
Do I have to use server/thin client or can i do this with the desktop
install? i.e. having authentication and user space on just one box but
run all the applications locally.
Thanks so much!
David

Thin clients would be a very quick way to do this, but installed desktops
have their advantages too.

You can store /home/ on a server with NFS, then mount that directory as
/home on each desktop.? This will mean that user's files and settings are
available from any computer.
You can use any of a number of centralised authentication schemes (LDAP,
NIS, AD) to allow consistent logins on any computer.? I've never needed to
make rules about which computers certain groups can login to, but I'm
guessing that should be pretty doable.

Dear Gavin,
Thanks so much for replying. I am starting this tomorrow !!!
The reason I think I'll do full desktop installs is that all the PC's
are identical and the spec is not good enough for a server and too
good for thin client (they had bought the gear already)...I don't want
to cannibalize the existing machines or spend anymore money.
Then again.... The school has an expansion plan to double the number
of computers. Maybe I can make 2 thin clients from 1 fat one :D
Regards
David

That makes reasonable sense.? The only trouble with desktop installs is the
maintenance is a lot greater.? You need to maintain the install on each
desktop individually.? Some of this can be automated, but thin clients
really are one machine.?
I'm not sure of the status at this point of the diskless fat client (or
whatever it's called).? The idea is that your desktops network boot, and
take their applications, etc. from the server as with thin clients, but
they actually run applications locally on the desktop, rather than running
them on the server.? In principal, this should give you a single install to
maintain, but use the computing power of the desktops.
I'm not honestly sure if this works well at this point though.? I've never
done it myself.
Gavin

Make sure vim is actually installed and put:
export EDITOR=vim
into .bashrc in your home directory. Next time you run bash, it should be
there for you. If you want to try it in your current shell, just run the
above command in that shell.

I installed ubuntu 8.04 amd64 on a terminal server, that we use in our
school adminitration. There are 8 different users and 5 different
printers. The problem is, that all users have the same default printer
as I and cannot change it. When they try to do so, they are asked for
their password at localhost, but their password is not accepted by the
printer configuration tool. We need different printers for different
users. Up to ubuntu 7.10 it was problem to set up different default
printers.
