Zimbra Upgrade Saga--Going from 4.0 to 6.0!

I needed to upgrade a client that had been lagging behind on Zimbra release upgrades. In fact, as of November 2009, they were still running 4.0!

Following advice from Zimbra, I decided to do the upgrade in jumps:
4.0.5 > 4.5.0
4.5.0 > 4.5.11
4.5.11 > 5.0.20
5.0.20 > 6.0.2

The problems started with the first upgrade...

Getting Your Android GPRS Data Connection Working with Airtel

You'll need your SIM card setup and the data capability enabled on the account. You also need to know your phone number.

You'll probably get an SMS message telling you that your phone the HTC DREA100 could not be configured automatically. That's OK.

Got to settings/wireless controls/mobile networks/access points. Click menu/add an access point.

Set the following:
Name: airtel mobile office
Proxy: <not set>
Port: <not set>
User Name: Your mobile number preceded by 91
Password: <not set>
Leave everything else as is.

That should do it. Save your settings and try to open the web browser and it should open right up. Once you have that, your email and calendar should also work.

UPDATE 11/2010:
I replaced my G1 with a Nexus One and was having trouble connecting. The rules above didn't apply. It turns out to be even simpler.

Internet Explorer Links & Shortcuts Hang or Display a White Window

I had a user that had problems with IE7 such that it wouldn't open when he tried to open a link saved to his desktop or the one on the "Quick Launch" shortcut.

The window would open, the "I'm doing something" indicator would spin, but only a white page would be displayed.

What I did was...

Strange Windows Backup Agent Error Message

I'm using's Windows Backup Agent at a client's to sync between a Windows Server and a Linux Server. It is being used as an intermediate backup solution while I work out some other issues.

Anyway, I initially configured the backup agent to run a one-time job to backup everything (per the instructions for setting it up) and it ran correctly.

However, when I went to change the profile to a scheduled job, or go to change ANYTHING on the profile as it turns out, I get an error that says, "NOTE The server you are trying to access is not covered by this software license" and it won't let me save any changes...

Installing Windows XP on a Inspiron 15 (1545) Preloaded with Vista

I picked up an Inspiron 15 to use as a general purpose internet accessing laptop and the only option for a pre-installed O/S was Vista--yuck. I have 7 of my 10 licenses of XP Pro I can still use from my MS Access Pack subscription, so I started down the road to repair... and ran into the BSOD wall (blue screen of death).

Not to worry, a little fiddling and...

Tech: SugarCRM importing dates problem

I was writing an module for SugarCRM so that users could regularly import data from another system. I kept getting dates that would only import as 2000-01-01 (01/01/2000).

The data was being read in correctly according to the logs and seemed to be processed as UTF-8 just fine, but the dates kept coming in defaulting to the standard "I don't know what this date is" SugarCRM result of 01-01-2000...

Quick tip: What to do when cron skips certain scripts

Many Unix/Linux distros come with cron already configured and a set of directories to drop your scripts in: /etc/cron.hourly, /etc/cron.daily, /etc/cron.weekly, and /etc/cron.monthly, depending on how frequently you want them to run.

This normally works just great, but my debian-based (Ubuntu) server wouldn't run some of the cron scripts that I had copied from my previous (CentOS) setup.

It turns out that this distro's "run-parts" command (which is called from crontab) skips scripts with a period (.) in the name, so my drupal.cron script never ran.

I simply renamed the script from drupal.cron to drupal and it runs "like clockwork".

The reason run-parts ignores the scripts with a period in the name is that, unless the LSB (Linux Standard Base) option is evoked, then, per the man page:

If neither the --lsbsysinit option nor the --regex option is given then the names must consist entirely of upper and lower case letters, digits, underscores, and hyphens.

What to do if Barracuda Anti-Spam is Blocking Office 2007 Attachments?

I support several Barracuda Anti-Spam servers and have been very happy with them.

However, one annoying problem has crept up since Office 2007 was released. Since Office 2007 uses zip compression to embed information in document files, my zip blocking was blocking otherwise legitimate attachments from passing through the filter.

The fix was simple enough...

Outlook Auto Complete

The Outlook auto-complete feature is kind of nice, but it can be unpredictable and strange when it starts to recommend certain addresses.

Here are a few tips to help get things under control...

How Big is That?

Ever hear somebody mention the size of a file in bytes, K, meg, or gigabytes and wonder how really big that file is?

Here are the definitions of each of these:

Kilobyte Same as Bytes
byte 8 bits 1
kilobyte 1,024 bytes 1,024
megabyte 1,024 kilobytes 1,048,576
gigabyte 1,024 megabytes 1,073,741,824
terabyte 1,024 gigabytes 1,099,511,627,776
petabyte 1,024 terabytes 1,125,899,906,842,624
exabyte 1,024 petabytes 1,152,921,504,606,846,976
zettabyte 1,024 exabytes 1,180,591,620,717,411,303,424
yottabyte 1,024 zettabytes 1,208,925,819,614,629,174,706,176

Which reminds me of a poem I just wrote:

the yottabyte, is a lotta byte
the biggest of all the prefix
and to think! the biggest is just
