# Workstation Autoconfiguration Script v1.0 by Simón A. Ruiz (simon.a.ruiz@gmail.com)
#
#     This script is designed to be run the first time a newly re-imaged
# workstation is booted up, which should be immediately following the boot
# process. It is called by /etc/rc.local when appropriate.
#     It relies on information from http://nordx-server/workstations.csv to
# determine what needs to be done.
#

LOGFILE=/home/administrator/scripts/autoconfig.log

#      First, let's determine where we are by searching for our MAC address
# in the workstation information file, and pass that information into usable
# variables.

MAC=`ifconfig | grep -m 1 HWaddr | awk -F 'HWaddr ' '{ print $2 }'`
wget http://nordx-server/workstations.csv
CSVLINE=`grep $MAC workstations.csv`
NEWNAME=`echo $CSVLINE | awk -F ',' '{ print $2 }'`
CLASSROOM=`echo $CSVLINE | awk -F ',' '{ print $3 }'`
WORKSTATION=`echo $CSVLINE | awk -F ',' '{ print $4 }'`
rm workstations.csv

echo "* We are $NEWNAME, located in $CLASSROOM, workstation number $WORKSTATION" >> $LOGFILE


# Let's rename this workstation both for Linux and for Samba

sed -e "s/nordx--image/$NEWNAME/" /etc/samba/smb.conf > /tmp/smb.conf
mv /tmp/smb.conf /etc/samba/smb.conf

echo "* Renamed Samba Hostname (/etc/samba/smb.conf)" >> $LOGFILE

sed -e "s/nordx--image/$NEWNAME/" /etc/hostname > /tmp/hostname
mv /tmp/hostname /etc/hostname

sed -e "s/nordx--image/$NEWNAME/" /etc/hosts > /tmp/hosts
mv /tmp/hosts /etc/hosts

echo "* Renamed Local Hostname to $NEWNAME" >> $LOGFILE


#      Now, let's configure the printer (We already have one installed) based
# on the classroom number.
#
#      The optimal way of doing this would be to install the printer here, but
# I was not able to figure out how to do that from the bash shell, so this is
# the simplest solution I could come up with at the time.
