Many applications which look for 32bit packages on your Debian/Ubuntu/Mint packages would need ia32-libs packages. Earlier it was possible to get this package installed and later on it has been removed from all distributions. The best way to get back the 32bit package support is to add the architecture to dpkg as follows:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs
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:
[[email protected] crontabs]# cat crontab >> crontab.zimbra
[[email protected] crontabs]# cat crontab.ldap >> crontab.zimbra
[[email protected] crontabs]# cat crontab.logger >> crontab.zimbra
[[email protected] crontabs]# cat crontab.mta >> crontab.zimbra
[[email protected] crontabs]# cat crontab.store >> crontab.zimbra
Finally,Load the crontab.zimbra file to crontab as follows:
[[email protected] 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’.
To reset the administrative password:
su – zimbra
To get a list of all administrators:
su – zimbra
To access the admin console:
Remember that the administrative console (sometimes) requires a full email address as the login name, so you may be using the correct password and the wrong login!

Running php scripts on apache in your Ubuntu desktop won’t be sweat at first. You might notice that php scripts start downloading when you start accessing them via browser. This is mainly because of small configuration issues that we can find on machine. If you have enabled userdir module (https://localhost/~yourusername), it contains a line to disable php values as follows in /etc/apache2/mods-enabled/php5.conf :
php_admin_value engine Off
All that you have to do is to disable the above line and restart apache to get php working.
I have been searching for the right alternative for managing my Xen VM’s and hosts. Its a pain to boot a Windows VM just for accessing XenCenter. You can download OpenXenManager from https://sourceforge.net/projects/openxenmanager/ or Install it on your Ubuntu machine using the following command:
#sudo apt-get install openxenmanager
PS: Running it from the source from SF.net link didn’t work for me on Ubuntu 12.04 but found it working after installing via apt-get.
Once installed, its very similar to working with the windows version of Citrix Xen Center.
Hope you too find it useful.
If you want to run virtual machines of different ip subnets from your OpenVZ node you will have to enable a parameter in /etc/vz/vz.conf.

Finding debian etch iso’s was little crucial when things doesn’t work well during upgrades. Especially when the drives go wrong and you have to continue running the good old distribution, better keep a copy of the ISO’s.
Here I found those ISO’s to get going.
