LTSP Version 4.1

2 ways to install LTSP-4.1:

There are 2 ways to install ltsp-4.1,

LTSP Installer
You can download the LTSP installer, and use that to download the rest of the packages. We've got a really nice fast mirror serving the packages. Take a look at the installation instructions
- OR -
ISO image
Download the ISO image and use the LTSP Installer to install from that. Take a look at ltsp ISO instructions for more info.

It includes the following:

New installer 'ltspadmin'. This new installer makes it much easier for us to update packages, and for you to install them. The installer will know which version of the packages you have installed, and it will query the package repository to see if there are updates available.
Change from XFree86 to Xorg. LTSP is now using the Xservers and libraries from the Xorg project, rather than the XFree86 project.
Local CD-Rom and Floppy support. Using Supermount and Samba on the client, and the auto-mounter on the server, we can now make the CD-Rom and floppy drives available to the users.
Sound support with esd and nasd. The client-side sound daemons are now included for esound and nasd, NAS support means that arts(KDE) works as well.
snmpd agent. We now have an snmpd agent on the client. You just need to enable it in lts.conf, with the following entries:
```
SNMPD = Y
    
```
New kernel, based on 2.4.26. Also, the kernel is now installed via the ltspadmin utility, as part of the ltsp installation procedure.
New documentation covering the features of LTSP-4.1.

LTSP Installer

Download and install the ltsp-utils package

RPM
TGZ
As root, run ltspadmin.
If you have a previos version LTSP already installed, it is recommended that you install the ltsp-4.1 packages into a separate directory, such as: /opt/ltsp-4.1. You can configure this with the ltspadmin utility.
Install ALL of the packages
Choose the 'Configure LTSP' menu item, which will cause it to run the ltspcfg utility. Use this utility to setup the services.

ISO image installation

Download here: ltsp ISO images

This ISO image of the LTSP-4.1 packages has been created for those who want to download a single file, and install it on multiple servers, without requiring additional downloads.

Installing LTSP from the ISO image:

Download the ISO image from the URL above. Save it on your system. For this example, we'll put it in /tmp.
Make sure you are either logged in as root, or you've switched to super user using 'su -' (Notice the '-', it's important)
Run md5sum on the downloaded file, and make sure the result matches the number above.
md5sum <ISO Image Name>
Mount the ISO image, using the loopback device:
mount -o loop /tmp/<ISO Image Name> /mnt
Install the ltsp-utils package
The ltsp-utils package is included on the ISO image.
If your system is RPM based (Redhat,Suse,Mandrake,...) you can install the ltsp-utils RPM package:
```
cd /mnt
rpm -ivh ltsp-utils-0.11-0.noarch.rpm
```
Or, if your system doesn't support RPM packages, you can install the TGZ package:
```
cp /mnt/ltsp-utils-0.11.tgz /tmp
cd /tmp
tar xvzf ltsp-utils-0.11.tgz
cd ltsp-utils
./install.sh
```
Whether you installed the RPM or the TGZ package, you'll end up with ltspadmin in /usr/sbin.
Run ltspadmin as root.
From the main menu in ltspadmin, choose:
"Configure the installer options"
Specify the pathname to the files:
file:///mnt

Notice that the value MUST be in the form of a URL, and also, notice that there are 3 slashes '///'. The first 2 slashes are part of the URL specification ("file://"), the 3rd slash is for the root directory on your server.
Leave the remaining options as is.
If you have a previos version LTSP already installed, it is recommended that you install the ltsp-4.1 packages into a separate directory, such as: /opt/ltsp-4.1. You can configure this with the ltspadmin utility.
Install ALL of the packages
Choose the 'Configure LTSP' menu item, which will cause it to run the ltspcfg utility. Use this utility to setup the services.
Unmount the ISO image from /mnt:
umount /mnt

Please report any problems you have with this ISO image to the ltsp-discuss mailing list, or contact me on the #ltsp IRC channel on irc.freenode.net.

Sound package:

The client-side sound support is already built into the ltsp-core packages, but you will still need a package installed on the server, to setup the environment to re-direct the sound to the workstation.

Richard June has created the sound packages, and you can get them at the links below:

There's some great info about sound on ltsp on the LTSP Wiki. The url is: http://wiki.ltsp.org/twiki/bin/view/Ltsp/Sound.

Local dev documentation:

For some brief documentation on setting up local floppy and cdrom, take a look at localdev.txt.

There's some great info about accessing local devices on the LTSP Wiki. The url is: http://wiki.ltsp.org/twiki/bin/view/Ltsp/LocalDrives.
