Comment 29 for bug 491940

My workaround for this problem is to send "halt" command to the underlying client o/s. Below are the steps needed, do in the server:

1. Chroot to the client environment:

$sudo chroot /opt/ltsp/i386

2. Define root password:

#passwd

3. Install openssh server and exit from chroot:

#apt-get install openssh-server
#exit

4. Update the client image:

$sudo ltsp-update-image

5. Create the down script:
#!/bin/bash
my_ip=`printenv|grep SSH_CONNECTION|sed 's/\(SSH_CONNECTION=\)\([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\)\(.*\)/\2/'`
ssh root@$my_ip halt

6. Place a launcher on client's desktop referring to the above script.
