Hello Thomas:
I've just solved it with LTSP 4.1 and SuSE9.1, working with KDE, it shoudn't
be difficult to change it for GNOME. I warn you, it's not the best solution,
in fact it's not a good solution but at least it's working now, i'm out of
time so i'll fix it later.
Mini-mini-HowTo - LTSP HelpDesk
1. Enable SSH
1.1 Modify /opt/ltsp/i386/etc/sshd_config
X11Forwarding yes
PidFile /tmp/sshd.pid
1.2 Copy the keys from your already configured ssh server
cp /etc/ssh/*key* /opt/ltsp/i386/etc/ssh/
1.3 Create the file /opt/ltsp/i386/etc/rc.local to launch ssh server
echo "Starting SSH"
/sbin/sshd &
1.4 Create the file /opt/ltsp/i386/etc/shadow with "your root password"
FIXME, PLEASE FIXME!!
root:EnrcyptedRootPassword:12698:0:10000::::
2. Enable permissions to access X at servers users
2.1 Add the script /home/XXX/.kde/Autostart/helpdesk.sh for each user (I've
recently read that DISABLE_ACCESS_CONTROL in lts.conf makes something
similar)
/usr/X11R6/bin/xhost +localhost &
3. Create the conection script for VNC at /usr/local/bin/shd
test -z "$1" && echo "Please type your client's IP/name .." && exit 1
cliente=$1
ssh -L 5900:localhost:5900 [EMAIL PROTECTED] 'export
DISPLAY=:0.0;/usr/X11R6/bin/x11vnc -display :0 -shared -localhost'
&>/dev/null &
sleep 8
vncviewer -encodings "tight hextile zlib" localhost:0 &>/dev/null &
exit 0
4. Make the conection to your client after he's started his KDE session, you
must know his IP/name.
shd ws092
With this method, the vnc server it's started in the client, only when you
need it, and, the "xhos +localhost " that each user executes when login in,
is , i think, safer than DISABLE_ACCESS_CONTROL.
Hope to help, and waiting for any comments, suggestions, reproachs from all
gurus at the list.
Thanks for such a great software as is LTSP!!!!!!
Greetings from Bolivia
