Dave Maclean, Managing Director explains ‘From our very first book published back in 2004, we’ve always focused on giving IT professionals the actionable knowledge they need to get the job done. As we look forward to the next 10 years, everything we do here at Packt will focus on helping those IT professionals, and the wider world, put software to work in innovative new ways.

We’re very excited to take our customers on this new journey with us, and we would like to thank them for coming this far with this special 10-day celebration, when we’ll be opening up our comprehensive range of titles for $10 each.

Fix Zimbra stats graph/cron jobs

If your zimbra scheduled tasks are not running or if you don’t see your stats graphs on admin panel, the first thing that you should check if zimbra’s cronjobs. When you reinstall/move your zimbra installation we normally tend to miss cron job setups required for zimbra.

To fix this, find the Zimbra crontabs directory at /opt/zimbra/zimbramon/crontabs

Now, lets put alwal the cronjob’s to a single file (just to make your job easier) as follows:

[root@zimbra crontabs]# cat crontab >> crontab.zimbra
[root@zimbra crontabs]# cat crontab.ldap >> crontab.zimbra
[root@zimbra crontabs]# cat crontab.logger >> crontab.zimbra
[root@zimbra crontabs]# cat crontab.mta >> crontab.zimbra
[root@zimbra crontabs]# cat crontab.store >> crontab.zimbra

Finally,Load the crontab.zimbra file to crontab as follows:

[root@zimbra crontabs]# crontab crontab.zimbra

Voila, that’s it. Wait for few minutes to start seeings the graphs. You can also verify the cornjobs by using ‘crontab -l’.

And I bought John Berger’s “Understanding a Photograph”. Having read John Berger’s kannada translation of “ways of seeing” by H.A Anilkumar, I got interested by the title of this book. An another step to understand the art of painting with light “PHOTOGRAPHY”.
