I'm currently running LTSP 4.2 under Debian 3.1 on a load of thin

I would like to upgrade. I am thinking of using LTSP 5 and Ubuntu.
I've come up with a number of problems and some of the docs are
getting a bit old and difficult to adapt to LTSP 5. So maybe there is
some major work there.
Problem 1 is my clients have etherboot roms not PXE so I need to
modify the way that works.
Problem 2. my Thin client server is different from my dhcp server how
do I configure my dhcp server up correctly so it can 1 server
different ltsp versions to different clients. Fortunately in my case
my dhcp server is running Linux and I can change it. But I would like
to have multiple thin client servers to spread load and have some
redundancy. (I have two currently that are selected at random using a
xdmcp broadcast using a modified startx script on the server)
That seams quite enough for now I really want to be able to run test
LTSP 5 in parell to start with on selected clients get it working
check everything works properly before releasing it to the world (well
the office anyway).
Peter.
I'm running LTSP5 at work with both PXE and Etherboot clients. The
Etherboot clients use a disk from rom-o-matic.net rather than a NIC with
an etherboot rom. I believe the TFTP server, tftpd-hpa, that is
installed with Ubuntu's LTSP can handle Etherboot and PXE requests, just
make sure your DHCP server is configured properly.
The problem I was having was with the kernel in that I could not get a
working etherboot ltsp kernel to work properly with ltsp 5.
Look for the file /etc/dhcpd.conf.example for how to setup your DHCP
server. 'root-path' and 'filename' are probably the most important
DHCP parameters if you have multiple LTSP servers so you can specify
which clients boot from which servers. The following link has more
information:
http://ltsp.mirrors.tds.net/pub/ltsp/docs/ltsp-4.1-en.html#AEN524
Why are you pointing me at yet more 4.1 docs?. 4.1 is very old I'm
running 4.2 and I'm trying to get 5 to work.
Peter
Back to answering ones own question..
https://help.ubuntu.com/community/UbuntuLTSP/LTSPEtherbootSetup
Actually I found a whole bunch of docs at
https://help.ubuntu.com/community/UbuntuLTSP
which are all very useful if not a little hidden.
I'm now trying to find some docs on LDM...
Peter.
Right I've got the etherboot kernel setup using the instructions I found above.
and I've set my dhcp server for one client to
host tc127 {
hardware ethernet 00:50:41:01:4c:bc;
fixed-address 192.168.0.127;
option root-path 192.168.0.33:/opt/ltsp/i386;
filename /ltsp/vmlinuz.etherboot;
next-server 192.168.0.33;
}
only problem now is the client keeps rebooting its self. It must be
doing somthing because if I move the vmlinuz.etherboot file out of the
way it says it can't find the file.
Peter.

Better than that, why not read the LTSP wiki page that describes how to

I've readed and used it.
This is my complete and exact /etc/dhcp3/dhcpd.conf file:
option subnet-mask255.255.255.0;
option broadcast-address 192.168.4.255;
option routers192.168.4.254;
option domain-name-servers192.168.4.254;
option domain-nameltsp;
get-lease-hostnames true;
next-server 192.168.4.101;
option root-path 192.168.4.101:/opt/ltsp-4.2/i386;
subnet 192.168.4.0 netmask 255.255.255.0 {
range 192.168.4.150 192.168.4.199;
filename lts/2.6.17.8-ltsp-1/pxelinux.0;
}
The workstation is assigned 192.168.4.199, and this is the result of
check-hostname:
# ./check_hostname.pl 192.168.4.199
hostname: ws199.ltsp
#
But the workstation does not get hostname:
bash-2.05# hostname
(none)
bash-2.05#
Any more idea?
Thanks everybody who is trying

[Ltsp-discuss] Chip Card readers for login
Just had an idea: Would it be possible to replace the ordinary login procedure via login manager (xdm, kdm, gdm...) by a chip card reader? We are discussing a way of making thin clients available within the ordinary classrooms for the teacher to make classbook entries etc. For this limited number of clients, a chip card system for login might be quite nice. The other terminals in the house should continue running with the common login manager. As I said: just an idea... :-) But has anyone here built such a thing? Thanks for your time!

[Ltsp-discuss] Monitor problem (Samsung SyncMaster 591sg)
Dear All, I have problem with one of my terminal. I've used Samsung SyncMaster 591sg (http://www.samsung.com/id/products/monitor/crt/591sg.asp) but it can not work on my terminal. It goes blank everytime I start the terminal but I can go to console mode (shell) using Ctrl+Alt+F2. I thought this is frequency problem (IMHO) .. Samsung SyncMaster 591sg Spec: Horizontal 30~55kHz Vertical50~120Hz What is the best lts.conf should I use so my monitor can operate well. I'm using OpenSuse 10.1 + LTSP 4.2u2 Thanks for your help.

[Ltsp-discuss] Somewhat Off-Topic - NFS Server failure
I don't think this is actually a problem with ltsp, but I'm just hoping someone has run into this problem before. I've imaged an LTSP server running SLES 10 and shipped off this image to IBM, so I need to deal with this problem about 1800 times without any human interaction. The problem is basically this: Upon first boot of this image, the time gets adjusted 44 hours into the future (maybe /etc/adjtime... Doesn't matter why, we can't change the image). The NFS service starts up with this time in place and of course so do all the other services. When I synch up with an NTP server, and the time is corrected, LTSP clients will no longer connect to NFS and successfully boot. If I set the time back to the future date, thin clients boot fine (the instant I change the date). My question is How do I safely correct the time backwards to the correct time without breaking NFS? Once again, this is not LTSP's fault, so I understand if no-one can help, but I figured I'd stick this question out there and see if anyone had come across this situation before. One option is to power down the server for 44 hours and then it should start working again... Unfortunately, we don't like that option very well.
