Écran de connexion Bactrack 5

Aujourd’hui je fait vous apprendre a mettre en place un ecran de connexion pour Backtrack 5r1.
Pour avoir un écran de connexion graphique, nous allons utilisé "kdm" (déjà présent dans Backtrack 5r1).

Maintenant il faut modifié le fichier /etc/init.d/kdm.(Perso j'utilise kwrite, éditeur par défaut de kde), et écrire se qui suit:

#!/bin/sh
### BEGIN INIT INFO
# Provides: x-display-manager kdm
# Required-Start: $local_fs $remote_fs hal
# Required-Stop: $local_fs $remote_fs hal
# Should-Start: console-screen
# Should-Stop: console-screen
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: X display manager for KDE
# Description: KDM manages a collection of X servers, which may be on the local host or remote machines.
### END INIT INFO
# /etc/init.d/kdm: start or stop the X display manager
# Script originally stolen from the xdm package
#
# description: K Display Manager
#
set -e

# Import the LSB init functions
. /lib/lsb/init-functions

# To start kdm even if it is not the default display manager, change
# HEED_DEFAULT_DISPLAY_MANAGER to "false."
HEED_DEFAULT_DISPLAY_MANAGER=true
DEFAULT_DISPLAY_MANAGER_FILE=/etc/X11/default-display-manager

PATH=/bin:/usr/bin:/sbin:/usr/sbin
DAEMON=/usr/bin/kdm
PIDFILE=/var/run/kdm.pid
UPGRADEFILE=/var/run/kdm.upgrade

# parameters to support kdm customization
KDMRC=/etc/kde4/kdm/kdmrc
BACKGROUNDRC=/etc/kde4/kdm/backgroundrc

#if configuration is changed by kdmtheme or other tools, don't do magick
if grep -q "Theme=@@@ToBeReplacedByDesktopBase@@@" ${KDMRC} && grep -q "Wallpaper=default_blue.jpg" ${BACKGROUNDRC}
then



KDMOVERRIDEDIR=/etc/default/kdm.d
KDMCFGDIR=/var/run/kdm
KDMCFG=$KDMCFGDIR/kdmrc
BACKGROUNDCFG=$KDMCFGDIR/backgroundrc

test -x $DAEMON || exit 0

# uncomment, if you want auto-logon to be runlevel-dependant
#test "$runlevel" || { runlevel=`runlevel`; runlevel=${runlevel#* }; }
#test "$runlevel" = 4 && ARG=-autolog || ARG=-noautolog

# uncomment, if you want tons of debug info in your syslog
#ARG="$ARG -debug 255"

# we use an alternative kdm master configuration file
ARG="$ARG -config $KDMCFG"

# we source overrides. run-parts sorts the list in a predictable order
if [ -d "$KDMOVERRIDEDIR" ]; then
for part in $(run-parts --list "$KDMOVERRIDEDIR" 2>/dev/null || true); do
. "$part"
done
fi

# If we upgraded the daemon, we can't use the --exec argument to
# start-stop-daemon since the inode will have changed. The risk here is that
# in a situation where the daemon died, its pidfile was not cleaned up, and
# some other process is now running under that pid, start-stop-daemon will send
# signals to an innocent process. However, this seems like a corner case.
# C'est la vie!
if [ -e $UPGRADEFILE ]; then
SSD_ARGS="--pidfile $PIDFILE --startas $DAEMON"
else
SSD_ARGS="--pidfile $PIDFILE --exec $DAEMON"
fi

stillrunning () {
if expr "$(cat /proc/$DAEMONPID/cmdline 2> /dev/null)" : "$DAEMON" > /dev/null 2>&1; then
true
else
# if the daemon does not remove its own pidfile, we will
rm -f $PIDFILE $UPGRADEFILE
false
fi;
}

case "$1" in
start)
if [ -e $DEFAULT_DISPLAY_MANAGER_FILE ] &&
[ "$HEED_DEFAULT_DISPLAY_MANAGER" = "true" ] &&
[ "$(cat $DEFAULT_DISPLAY_MANAGER_FILE)" != "$DAEMON" ]; then
echo "Not starting K Display Manager (kdm); it is not the default display manager."
else
echo -n "Starting K Display Manager: kdm"
start-stop-daemon --start --quiet $SSD_ARGS -- $ARG || echo -n " already running"
echo "."

/etc/init.d/kdm stop
if [ -f $PIDFILE ]; then
if stillrunning; then
exit 1

fi
/etc/init.d/kdm start

fi

force-reload)
/etc/init.d/kdm reload
;;

stop)
echo -n "Stopping K Display Manager: kdm"
if [ ! -f $PIDFILE ]; then
echo " not running ($PIDFILE not found)."
exit 0
else
DAEMONPID=$(cat $PIDFILE | tr -d '[:blank:]')
KILLCOUNT=1
if [ ! -e $UPGRADEFILE ]; then
if start-stop-daemon --stop --quiet $SSD_ARGS; then
# give kdm's signal handler a second to catch its breath
sleep 1
else
echo -n " not running"
fi
fi
while [ $KILLCOUNT -le 5 ]; do
if stillrunning; then
kill $DAEMONPID
else
break
fi
sleep 1
KILLCOUNT=$(( $KILLCOUNT + 1 ))
done
if stillrunning; then
echo -n " not responding to TERM signal (pid $DAEMONPID)"
else
rm -f $UPGRADEFILE
fi
fi
echo "."
;;
status)
status_of_proc -p "$PIDFILE" "$DAEMON" kdm && exit 0 || exit $?
;;

*)
echo "Usage: /etc/init.d/kdm {start|stop|restart|reload|force-reload|status}"
exit 1
;;
esac

exit 0

Ensuite il faut faire un update de "KDM":

update-rc.d kdm defaults

Voila Maintenant il ne vous reste plus qu'a rebooter votre pc et d'admirer le résultat, qui d’après moi et quand même plus agréable que des lignes pour se connecter (je n'est rien contre les lignes de commandes je vous rassure).
