Kiwi-Ltsp softphones and sound.

With thanks to Jigish Gohil cyberorg@opensuse.org for his help

Objective.

To install a softphone as a local app on kiwi-ltsp.

Steps Along the Way

# Setting up kiwi-ltsp for the first time on Opensuse 11.4
 After installing the ltsp package from the opensuse site, kiwi-ltsp is setup<!--
 the root for the image is  :- /srv/kiwi-ltsp-nfs-i386

I chose 10.0.0.254 as my server
#Use yast to setup network card eth0 as 10.0.0.254
#edit /etc/sysconf/kiwi-ltsp for the following

SUSE_VERSION="11.3"
SERVER_IPS="10.0.0.254"
LTSP_LOCALAPPS="twinkle"
suse_1130_INSTALL_SOURCE=/mnt/11.3
(if the above is not mounted the download will be around 260MB)
<pre>
#Mount /dev/cdrom /dev/11.3  for the 11.3 opensuse distribution
#Use yast to create repositories
 http://download.opensuse.org/update/11.3/
 openSUSE-11.3 11.3-1.82 DVD
===Using mkiwi-ltsp-setup===
 kiwi-ltsp-setup -h       # read carefully.
 kiwi-ltsp-setup -s  will build a new root image
 (if used with the -l option , 
 the wrong /lib/modules get loaded and there will be no drivers for most things)

===Setup Server Configuration===
# The tftpd has to be run as root
# The sshd has to be running (default is not running after install)
the above 2 can be done using yast.
# Use easy-ltsp to setup the variables you require.
 The add button gives a selection of options.
 SOUND=TRUE   is a good one :)
 LDM_SERVER=10.0.0.254  (edit by hand) (did not work for me)
 (I changed the  server ip address
 in /srv/kiwi-ltsp-nfs-i386/usr/share/ltsp/ltsp_config
 set at 192.168.0.254 !!!!!!!!!!!!!!!##################### )
 This file does not get changed by kiwi-ltsp-setup -c
# The image has to be mounted using NBD
  kiwi-ltsp-setup --nbd
  kiwi-ltsp-setup -c   (essential if you decide to change the network)
 (I also ran -d -e -t )
  will setup all the config files required.
# Build the image
  kiwi-ltsp-setup -l2
 cd /srv/kiwi-ltsp
 mv ltsp.... to i386.img   (eg mv ltsp-suse-11.3.i686-0.0.1  i386.img)
 The client should boot.

===NO RESPONSE FROM SERVER=== 
 Probably the ip address is wrong.
===Backup the Clean Image===
 cp -a /srv /srv.version1
===Customizing the Image===
#Add a user to the client image.
===CHROOT===
<pre>
#!/bin/bash
#file /usr/local/bin/gochroot
root_dir="/srv/kiwi-ltsp-nfs-i386"
mount -o bind /dev $root_dir/dev
mount -o bind /proc $root_dir/proc
chroot  $root_dir
umount $root_dir/proc
echo "  exit $root_dir"
gochroot
useradd -gid 0 user1
passwd user1    # create a password
Edit the file /etc/passwd file and change the uid of user1 to 0
save the changes
run   pwconv
exit

.

You have now created a user1 on the client with full root powers.

root password

(Changing the image password for root caused image boot failure
DO NOT CHANGE ROOT PASSWORD)

Adding a package to the client (Localapp)

I added vim.
Use yast to setup the repositories required.
i.e. the install dvd and the 11.3 updates
http://download.opensuse.org/update/11.3/
and installation dvd
This operation will save a repos.d directory in /etc/zypp
cp -a  /etc/zypp/repo.d /srv/kiwi-ltsp-nfs-i386/etc/zypp
update the repository info on the root image
zypper --root /srv/kiwi-ltsp-nfs-i386 refresh
zypper --root /srv/kiwi-ltsp-nfs install vim

Sound does not work in Twinkle.

Inspite of all the rules and permissions being set by the install, 
the sound does not work on the localapp Twinkle.
The permissions of /dev/snd and /dev/dsp are set to 660 owner root , group audio
pulse is a member of the audio group.
A solution is to change the permissions to 666

rc_exit
****************************************************************

Set startup links in the rc.d directories.

chroot to the image
cd /etc/init.d

run the program chkconfig to make it all work !!!!!
chkconfig -s mod_snd 2 3
exit from the image
NB make sure you unmount anything that you mount before leaving chroot.

Build the Customized Image

kiwi-ltsp-setup -l2
mv ltsp----.img to i386.img
ALL DONE

The Way It Should Be Done

The documented way below did not work for me.

root password

/usr/share/kiwi/images/ltsp/suse-11.3/config.xml
<users group="users">
<user name="root"
pwd="$2a$10$90AjhfXU2YIwTRrIftBauecvWXVuaNZ6JLM2IpWi0svu2kO16le9e"
home="/root"/>
</users>

Repositories Setup

/usr/share/image/kiwi/suse-11.3/config.xml 
<!--
 Note:  first repository obligatory should be main 
		all other repository should be below 
-->

setup startup command on client

chmod 666 /dev/snd/*
chmod 666 /dev/dsp
to /usr/share/kiwi/images/ltsp/suse-11.3/root/etc/init.d/boot.local
chmod +x  /usr/share/kiwi/images/ltsp/suse-11.3/root/etc/init.d/boot.local
