I developed the Ubuntu version Citrix thin client. To follow the same naming convention as TC-Citrix, I name it UT-Citrix.

Here are the key scripts:

checkip

#!/bin/bash

#wait for the DHCP ready
while ! ifconfig eth0 | grep ‘inet addr’ >/dev/null 2>&1
do
echo
sleep 2
done

sysprep

#!/bin/bash
#rename the computer
echo
HOSTNAME=UT-`ifconfig | grep ‘eth0’ | tr -s ‘ ‘ | cut -d ‘ ‘ -f5 | sed ‘s/://g’`
rm -f /etc/hostname
echo $HOSTNAME > /etc/hostname
hostname -F /etc/hostname
rm -f /etc/hosts
echo “127.0.0.1 localhost” > /etc/hosts
echo “127.0.0.1 $HOSTNAME” >> /etc/hosts

#generate new SSH key
rm /etc/ssh/ssh_host_*
dpkg-reconfigure openssh-server

sleep 3
