samba - Nov 2006 - Trouble doing a remote shutdown of a linux machine through samba

Is it possible to shutdown a Linux computer through Samba using the 
shutdown command in Windows XP and 2003? I've tried:

shutdown /r /m hostname

This doesn't work and results in Windows reporting "The remote
procedure
call failed.' in the command window. The Samba log shows the following:

I'm using Samba 3.0.21b on a Slackware 9.1 install. I've also tried 
using this command to shutdown/restart a Samba 3.0.23c server running on 
Slackware 10.1 with the same results.

Any suggestions would be greatly appreciated. Does Samba allow for this 
at all?

Regards,

Tom

I'm not sure if you can do this but I would suggest doing
this via ssh.

Regards,
Franz

Have you set the "shutdown script" and "abort shutdown
script"
directives in your Samba configuration?

abort shutdown script = /sbin/shutdown -c
shutdown script = shutdown script = /etc/samba/shutdown.sh %z %t %r %f

cat /etc/samba/shutdown.sh
---<clip>----
#!/bin/bash
# %z - Message = $1
# %t - Seconds before shutdown starts = $2
# %r - Reboot switch (-r) = $3
# %f - Force switch (-f) = $4

$time=$2
let "time=time/60"
let "time++"
/sbin/shutdown $3 $4 +$time $1 &
---</clip>----

This is all in the smb.conf manual page.

I have checked this and it does look correct:

---------- smb.conf -------------
shutdown script = /etc/samba/shutdown.sh %z %t %r %f
abort shutdown script = /sbin/shutdown -c
---------------------------------

--------- shutdown.sh -----------
#!/bin/bash

/sbin/shutdown $3 $4 $2 $1 &
---------------------------------

If a more detailed log file would help I can get it for the list; but as 
of right now, all I get in the log file is the following:

Yes.  Remote shutdown is supported.
