RE: Hate launchd miss crontab



Sean,

Thanks for all the info....very helpful! 

But everything looks fine....just nothing is running dealing with cron or daily, weekly, monthly scripts as well.

I am using one of the buggy (Late 2004) G5's 1.8ghz machines so that could be an issue as well.  Still waiting for Apple to get an SMU Firmware update for these things released.   It could be caused by that I am guessing.

I just tried running the 10.4.3 (Combo) update to see if that would fix anything and still no luck.  I have tried just about everything.

Thanks,

Dan

Dan,

Make sure that cron is loaded into launchd.  My backup server runs about
50-60 individual processes, and I don't want to create that many launchd
configs, so I'm using the crontab with very good results.

To check if launchd knows about cron:
sudo launchctl list

You want to see com.vix.cron in the list.  If it's not, then you need to
load it:
sudo launchctl load /System/Library/LaunchDaemons/com.vix.cron.plist

If your machine complains about the com.vix.cron.plist file (like it's not
there or anything), this is what mine looks like (the default version):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd";>
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>com.vix.cron</string>
        <key>ProgramArguments</key>
        <array>
                <string>/usr/sbin/cron</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>WatchPaths</key>
        <array>
                <string>/etc/crontab</string>
        </array>
        <key>QueueDirectories</key>
        <array>
                <string>/var/cron/tabs</string>
        </array>
</dict>
</plist>


To then start it:
sudo launchctl start com.vix.cron

Maybe this will help.  I've never had to do this, but maybe my setup is
different than yours.
