autolog error message

["Ariel O. Garcia" <ariel@cab.cnea.gov.ar>]

Hello,
      I am running autolog (up-to-date potato), but I get the following
errors:

---------------------------------------
From: Cron Daemon <root@cabtep4>
Subject: Cron <root@cabtep4> test -x /usr/sbin/autolog && /usr/sbin/autolog

autologout: Can't get status of user's terminal (No such file or directory)
---------------------------------------

What does this mean?

my /etc/autolog.conf is:
---------------------------------------
name=root	line=tty[1-7]	idle=15	grace=100 clear
line=ttyS[1-2]			idle=15	grace=50 clear
line=tty[1-7]			idle=20	grace=50 clear
line=pts/.*			idle=90 grace=50 nomail
# line=ptyp.*			idle=30	grace=50 nomail nolog
idle=20					grace=50
---------------------------------------

A second question: I would like to have autolog close idle
console logins (/dev/tty's, that works ok), idle telnets into that 
machine and idle X_sessions (:0 for instance) but _not_ xterms inside :0
Both telnet sessions and xterms have /dev/pts/#  as device... how could I
treat them differently?

I searched the docs and the debian mailing lists but couldn't find that.

Anyway, I would like to know if autolog is the
default/preferred/recommended way of closing idle open
sessions in debian potato?

Please CC to me as I am not subscribed to this list, thanks!

Rgds, Ariel
