The shell is for the local machine. There is no valid login by
default, so it won't work unless you have created logins in your
chroot.

On the other hand, if you have created user accounts on the server,
these are not valid in the thin client's shell. You must first
establish a connection to the server, and I don't know if LTSP
supports that without some sort of desktop session being established
first, such as ldm.

Possibly you could just choose xterm as your login session instead of
gnome if you are just looking for a shell on the server?

login issues

Let's say for argument's sake that I've migrated users to a new ltsp 
machine (because I have).

I moved home directories and  moved the users, passwords, shadow, and 
groups to the new machine and appended them to the appropriate files.

When i reboot the machine, there are all my users waiting to be logged 
in, so that's good.

However, some of them are not able to log in via ltsp.  It just goes 
blank for a second and logs them out.

Any idea what that might be?  I'm going to be looking into it today, but 
if anyone has any ideas, I'm willing to hear them.

The most common causes of slowness in LTSP seen recently are flow
control and 32-bit server OS (with kernel paging not enabled).

I would check the /var/log/auth.log and /var/log/messages to see what
happens. Could be messed up permissions and DE (Gnome?) have problems
with the files.
If you create a new user , can you login with that one?

Re: login issues

Yes.

Also, good suggestion.  I'm working through all the users now, finding 
the ones that can and can't log in.  I'm also checking things like 
bashrc and their profile to see if maybe it's trying to grab files that 
no longer exist.

Moving LTSP Server

Hi list, 

I'm new here and have the following problem.
In our school we use 2 LTSP systems, both on Ubuntu Server 8 with LTSP
4.
Now on one system a HD of the RAID1 is defected. I bought new HD's that
are bigger and would like to install the newer version of the server
with ltsp5.
I saw on the server that ltsp runs in its own subdirectory.
Is it possible to just move the old ltsp installation to the new hd's??
Important are the users and their /homedirs.

thanks and greetings from belgium, Sascha

Not exactly. The LTSP directory is a chrooted directory only used to send the 
basical system to the thin-clients at boot. It is not used after that.

Don't be confuse with the LTSP part and the software and user accounts part:
- LTSP is only the little chrooted system that is downloaded by the thin-
clients at boot, plus the various servers softwares (dhcp, tftp, ssh, 
NFS/NBD), in charge to deliver the chrooted system or the access to the /home 
directory. Those servers are not installed in the chroot part, but in the 
normal file system of the server.
- On the server reside all the software and user accounts that the thin-
clients will access.

So for your new installation, you just need to setup the LTSP and copy the 
user's account datas (/etc/passwd, /etc/shadow and /home directory) on the new 
system.

Re: Moving LTSP Server

Hello.

I think you got to make a fresh install. Moving LTSP directory, won't 
move /home and that directory is Build for your Ubuntu 8.** system.

In my case i got a disk with /home, so when i need to upgrade, i just 
umount /home, save /etc/passwd /etc/gshadow, /etc/gshadow and /etc/group.

Then, fresh install, copy all 4 files to new installation, mount /home 
and it's rolling.

You may find some troubles with the user you create and his /home, but 
making chmod "user":"user" /home/user solves them.

My LTSP is in a Virtual Machine, so it's easier to create a Disk to 
/home and keep RAID1.

Regards!

Re: Moving LTSP Server

Hello again.

One more thing that i missed...
in the files:
/etc/passwd
/etc/gshadow
/etc/gshadow
/etc/group
you can't "copy - paste" them, only copy the real users. You must leave 
the system users from the fresh install.

Regards

Boot menu?

Hi there List,

I have several users using LTSP to access Windows Desktops via rdesktop. 
Each user accesses a different Windows instance (running in VM's).

My lts.conf directs users' rdesktop to a specific Windows instance based 
on the client's MAC address.

My question is this: if I want a user to be able to choose from two or 
more possibilities, can I make lts.conf call up a script to show a text 
menu to the user, and then launch rdesktop with the correct options?

I would appreciate step-by-step instructions since I am not very fluent 
in LTSP...

Thanks in advance!

PS- my server is LTSP 5 running on Ubuntu 8.10.
