Hi folks!

New to this forum, just wanted to ask :

I have CRON set up to run 3 tasks

at 12:30 AM CST -- run dropbox and backup data

at 12:45 AM CST - Run spotify and sync any new songs I added to the list

at 4:30 AM CST - Log off

The reason is because I am on Sat. Internet and I cant do any of those things during the day for it eating my data cap up.



So it looks like by /var/log/syslog everything ran BUT logging off:

Dec 22 00:30:01 COMPAQ CRON[24886]: (chris) CMD (dropbox start -i)
Dec 22 00:30:04 COMPAQ CRON[24885]: (CRON) info (No MTA installed, discarding output)
Dec 22 00:45:01 COMPAQ CRON[24968]: (chris) CMD (spotify )
Dec 22 00:45:01 COMPAQ CRON[24967]: (CRON) info (No MTA installed, discarding output)
Dec 22 01:17:01 COMPAQ CRON[24976]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly)
Dec 22 02:17:01 COMPAQ CRON[24990]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly)
Dec 22 03:17:01 COMPAQ CRON[25006]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly)
Dec 22 04:17:01 COMPAQ CRON[25024]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly)
Dec 22 04:30:01 COMPAQ CRON[25029]: (chris) CMD (qdbus org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.logout -1 -1 -1)
Dec 22 04:30:01 COMPAQ CRON[25028]: (CRON) info (No MTA installed, discarding output)

so how come it didnt log off?

Also it was suppose to email me and let me know if everything went ok but it didnt do that either =[



how did I input the tasks for cron?
----------------------------------------------------
I installed the Cron front end for KDE and put all the tasks in that way. then went K menu typed in task.... and clicked on the icon.


Thank you,
Christopher

Cron & Posting

There is the Postfix:

https://help.ubuntu.com/community/Postfix
https://help.ubuntu.com/10.04/serverguide/postfix.html

At here:

Installing the mailutils and setting the local post.




Trying the dbus command -> It is not working but there is post for me:

Could not connect to D-Bus server: org.freedesktop.DBus.Error.NotSupported: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

? q
Saved 1 message in /home/rog132/mbox

The problem is that the cron is 'special' - it needs the 'export DISPLAY=:0' before the command.

export DISPLAY=:0 && qdbus org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.logout -1 -1 -1

(note! - the KCron doesn't like the export - the export part was added with the 'crontab -e')

Now the logout is working but there are still error mail:

Error: org.freedesktop.DBus.Error.NoReply
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Other options to 'logout': http://askubuntu.com/questions/15795...a-the-terminal. Maybe the 'pkill user' works without the 'export Display'.

The KShutdown (http://kshutdown.sourceforge.net/ ) has a clean command option:

man kshutdown

NAME
kshutdown - A Shut Down Utility for KDE

SYNOPSIS
kshutdown [Qt-options] [KDE-options] [options] time


-l, --logout
End current session

It is working from the konsole but the Cron is whining of the dbus...

Hi

Sorry I can't offer any technical advice, I'm a noob to *nix. I 'converted' to Ubuntu back in Oct 2011 from XP (which was by far the BEST move I EVER did). But my understanding is that Dropbox is a 'copy' of certain folders that you want to share, so if you delete anything in the folder, it also removes it from the online 'mirror'. Please enlighten me as to whether I am wrong or not!
