+## Note, to get this to work as it is currently typed you need
+##
+## 1. to run an application as root
+## 2. add the following groups to the /etc/group file:
+##		floppy, games, sound
+##
+#
+# *** Please note that giving group membership on a session basis is
+# *** NOT inherently secure. If a user can create an executable that
+# *** is setgid a group that they are infrequently given membership
+# *** of, they can basically obtain group membership any time they
+# *** like. Example: games are allowed between the hours of 6pm and 6am
+# *** user joe logs in at 7pm writes a small C-program toplay.c that
+# *** invokes their favorite shell, compiles it and does
+# *** "chgrp games toplay; chmod g+s toplay". They are basically able
+# *** to play games any time... You have been warned. AGM
+#
+# this is an example configuration file for the pam_group module. Its
+# syntax is based on that of the pam_time module and (at some point in
+# the distant past was inspired by the 'shadow' package)
+#
+# the syntax of the lines is as follows:
+#
+#       services;ttys;users;times;groups
+#
+# white space is ignored and lines maybe extended with '\\n' (escaped
+# newlines). From reading these comments, it is clear that
+# text following a '#' is ignored to the end of the line.
+#
+# the first four fields are described in the pam_time directory.
+# The only difference for these is how the time field is interpretted:
+# it is used to indicate "when" these groups are to be given to the user.
+#
+# groups
+#	The (comma or space separated) list of groups that the user 
+#	inherits membership of. These groups are added if the previous
+#	fields are satisfied by the user's request
+#
+
+#
+# Here is a simple example: running 'xsh' on tty* (any ttyXXX device),
+# the user 'us' is given access to the floppy (through membership of
+# the floppy group)
+#
+
+#xsh;tty*&!ttyp*;us;Al0000-2400;floppy
+# another example: running 'xsh' on tty* (any ttyXXX device),
+# the user 'sword' is given access to games (through membership of
+# the sound and play group) after work hours.  (The games group owns
+# high-score files and so on, so don't ever give users access to it.)
+#
+
+#xsh; tty* ;sword;!Wk0900-1800;sound, play
+#xsh; tty* ;*;Al0900-1800;floppy
+
+*; tty*&!ttyp*; *; Al0000-2400; audio,cdrom
+*; :0; *; Al0000-2400; audio,cdrom,floppy,plugdev,video,powerdev
+*; :0;*;Al0000-2400;lpadmin

+Instala un script que al hacer login el profesor en el equipo limpia la
+cola de impresión de todas las impresoras y las reinicia y activa.
+Evitamos colas de impresión con trabajos atascados durante días.
+Es mas práctico que hacer que el profesor lo haga interactivamente, ya que
+pasa de hacerlo y además olvida que ha mandado un trabajo, dejando el
+trabajo encolado.
+
+Pone un script en /etc/Xsession.d que hace la limpieza de colas y activacion.
+Además, modifica /etc/security/group.conf para que todos los usuarios logados
+en :0 pertenezcan al grupo lpadmin (para poder ejecutar comandos
+cups de limpizeza y activacion).
