How to ask for root password every time X starts?

[watchdog]

I have modified /etc/inittab for asking a password for root login at boot.

Code: Select all

::sysinit:/etc/rc.d/rc.sysinit
tty1::respawn:getty 38400 tty1
tty2::respawn:getty 38400 tty2
::ctrlaltdel:/sbin/reboot

I changed the root password from woofwoof with the command:

Code: Select all

passwd

Is there a way for asking that password every time X starts? I think xwin script should be modified.

Roughly, I renamed /usr/bin/xwin as xwin-exec and created a script in /usr/bin named xwin with the following content:

Code: Select all

#!/bin/sh
echo -n "Password: "
read -rs password
echo
if [[ "$password" == "xxxxxxxxx" ]]; then
  echo "Password correct!"
  /usr/bin/xwin-exec
else
  echo "Password wrong."
  reboot
fi

for everytime you might have to drop out of the shell you are in, back into the login shell again,
ie, logout when the xsession terminates
