How to debug wake up script

I am struggling with what should be easy.

I am attempting to setup wakeup, I can manually set the
/proc/acpi/alarm just using a cat '2008.03.29 etc' >
/procacpi/alarm
and shutdown teh system. This will then start ok.

I have the script in my myth setup using "sudo
/usr/local/bin/my-wakeup.sh $time" and the mythtv user
is set sudo
NOPASSWD for the script, but it does not appear to be run on
mythtv
shutdown.

In the script it also writes a time stamp to a plain text
file and
that does not get written so I know it's not running.

The script can be run with sudo /usr/local/bin/my-wakeup.sh
on the
command line and it works and writes to the acpi alarm and
my text
file..

How can I debug to find out error messages? I cannot find
anything in
my /var/log/messages and am now stuck.

Thanks for any help on this.

-Greg

I could be wrong, but I seem to recall that the script only
gets run
when the machine does an automatic shutdown (on idle).  If
you're
stuck for things to try then you could look at the 'shutdown
on idle'
settings.

...and look in the backend log for any error messages.

If you used the instructions on the wiki then you probably
haven't got 
things set up quite right. I have just upgraded my parents
setup to use 
acpi instead of nvram-wakeup after upgrading the kernel to
one that now 
supports ACPI and noticed the wiki instructions where
misleading, 
outdated and just plain wrong in a few places.

These are the settings I used, from memory so may be
slightly wrong  
but should point you in the right direction. I have things
setup to use 
MythWelcome but there is no reason these settings wont work
if you don't 
use MythWelcome.

You should run mythtv-setup and on the Shutdown/Wakeup
Options page set 
the following settings:

        
        Block shutdown before
        client connected:                       should be
unchecked
        Idletimeout (secs):                    any value
greater that 0
        Wakeup time format:                yyyy-MM-ddThh:mm
        Set wakeup time command:       mythshutdown
--setwakeup $time
        Server Halt command:               mythshutdown
--shutdown
        Pre shutdown check command:   mythshutdown --check


Now run mythwelcome --setup and set the following settings:

        command to set wakeup time      sudo sh -c 'echo
$time > 
/proc/acpi/alarm'                           
                                                         you
could call 
a script here like this:-
                                                         
set_acpi_wakeup.sh $time
                                    
        wakeup time format                   yyyy-MM-dd
hh:mm:ss
                                                        this
is the 
format of the time passed to the above command
 
        nvram-wakeup restart              <blank>
        command                                 nvram-wakeup
required a 
reboot before the time would stick but
                                                       ACPI
doesn't seem 
to require it so I left this blank.
                           
       Poweroff Command                  shutdown -h now
    
       Reboot Command                      /sbin/reboot

Some of these commands may require root privileges to work
so depending 
on what user
mythbackend is run under you may need to play about with
sudo to get 
things to work.

If you still have problems then try running each command as
the user 
that the backend
uses to see where it's failing. This is roughly the sequence
that the BE 
uses when it's
doing the shutting down.

1. abort if we have any clients still attached (usually any
mythfrontends).

2. call the 'mythshutdown --check' and abort if it doesn't
return 0.

3. if there are any upcoming recordings call 'mythshutdown
--setwakeup 
$time' with the time of the next recording.

4. call mythshutdown --shutdown
    a)  mythshutdown now works out the time of the next
wakeup which 
will either be
        the time of the next recording or the start time of
the next 
wakeup period
        if any are set.
   
    b)  if there is no next wakeup time then just call
'shutdown -h now'.

    c)  call sudo sh -c 'echo $time > /proc/acpi/alarm'
to set the next 
wakeup time in the rtc.

    d)  if we have a 'nvram-wakeup restart command' set run
that then 
the reboot command
         if not set just call the power off command.

5. if we're still here then something went wrong so go back
to 1 and try 
again.
