Interesting read over at CRN regarding VMware’s End User Computing products and upcoming release dates. It sounds that they’ve some insights but unfortunately only rumors.
The updates, outlined in an internal company document viewed by CRN, will be announced on May 2. They include View 5.1, the latest version of VMware’s desktop virtualization software; an on premise version of Horizon Application Manager, a VMware-hosted identity management service; and Zimbra 7.2, an update to the company’s open source email and collaboration software.
You may have heard about VMware’s new Project Octopus during VMworld in Las Vegas. If not here is a quick summary. Project Octopus enables users to access files on any device from anywhere and share them with anyone. The solution can be deployed on premiese or consumed through a service provider. It integrates easily with your existing infrastructure and applications.

Back in April I’ve published a post about VMware View on a brand new Fujitsu Q550 tablet PC. At this time the device was a prototype and I had the chance to test it. It was great to work with it event if it was a prototype. In the last few month was a lot of buzz going on about tablet computers. Almost every vendor released a device but there are a lot of differences between the tablets. First of all the platform and the operating systems. Most of the hardware vendors developed their devices on a ARM based platform but there are also ATOM based computers. One of those is the Fujitsu Q550. It’s not running Android, no there is a standard Windows operating system installed. Yes, that’s true – a standard Windows OS what gives you loads of advantages but also a few challenges. As I’m really interested in how a user can work with a tablet and the cloud only I’ll try this for a week. As the tablet is Windows 7 based I’ve an advantage because I can run my email software Zimbra Desktops as I would run it on my laptop. Good for me as this gives me offline access. Additionally I want to use the VMware View 4.6 client to access my work desktop whenever I’ve a network connection. Let’s see how this all works.
To clarify one point up front – The Fujitsu Q550 is not a consumer device, it was released to match the needs of enterprises.
The Q550 includes some great features which are necessary for using a tablet in the business.
- Dual digitizer – Touch screen but also a digitizer pen to make notes with Microsoft OneNote for example.
- Fingerprint reader for authentication
- SmartCard reader for authentication
- Changeable battery
- USB port
- 2 Cameras for collaboration (Front View and Webcam)
- Integrated microphone and loudspeaker, earphone plug
- SD Card reader
From my view this device can easily be handled by IT departments as it is a standard Windows device which can be integrated in the companies Active Directory. You could even use Group Policy Objects or a software deployment software with it.
Disadvantages? Sure! Windows is not optimized for touch tablets! It’s great to have the dual digitizer with the pen as this helps a lot. I’ll also check how a bluetooth mouse and keyboard or a USB replicator will help me when working on the desk.
We’ll see! Let’s get started with testing. You’ll see some posts about my experiences in the next days.
Two weeks ago I’ve decided to update my Zimbra Desktop Client 2.0 to the new beta version 7. All went well so far and I could see the new look and feel. Really nice changes to the UI. After a few days I had to change my domain password which is also my Zimbra password because the server is connected to the Active Directory. So good so far but I couldn’t open my Zimbra Desktop Beta 7 Client anymore. I always got the error message: service.FAILURE: system failure: Unable to unmarshal response for AuthResponse. I could find a thread in the Zimbra forums which helped me a bit and also a colleague was facing the issue and he could fix it. I’ve tried to fix the issue with his instruction but it didn’t worked.
He gave me the following hint:
Delete your email signature and reset the language to English via the Zimbra web interface.
In the forums I found some information which said:
If your signature or any of your other account settings in ZWC contain UTF-8 characters you will get this error. You can get around the problem for now by removing those characters from your signature.
I’ve tried that workaround and deleted the signature and set the language to English but still no chance to login via Zimbra Desktop.
After a few thought I came up with another idea! Checking the zdesktop.log file might be a good way to get more information on the issue. On Mac OS X you can find the file in the path /Users/christoph/Library/Zimbra Desktop/log. Of course it helped me. I found out that there where more UTF-8 characters in the AuthResponse. Both the signature and the Out-of-Office notification contained the UTF-8 characters. After deleting also the OOO-message I could login again. That’s a first workaround but I think this will be fixed in the next beta version of the Zimbra Desktop client. I hope this helps.
This week my companies email account has changed from Exchange to Zimbra Collaboration Server due to my participation in an internal pilot program. This is great because I’m already using the Zimbra server and also the desktop client privately for a while and I’m really happy with it. What I’ve never thought about before is the backup procedure of my local stored folders which are not synchronized with the cloud. In my private environment that was never an issue for me because my email account has no restricted size. With the companies account I got a limit of 2 GB which is a lot, but not enough when storing all PDF and PPT files as well as the archived mails. Because I’m a Mac user and usually using Time Machine for my backup I was wondering if there is another way to do a backup of the Zimbra Desktop data including my local stored folders. Some googleing gave me the final hint!
For quite a while now I’ve tried to get Zimbra Desktop working with my Zimbra Collaboration Server (ZCS) but I couldn’t get it running. I’ve always received an error message saying: account.INVALID_ATTR_VALUE: zimbraPrefForwardIncludeOriginalText must be one of: …” for me just something like: $&%°!%!" so I left it for a while. But again I thought there must be a way to get it running and I investigated the issue.
Due to some limitations with the Zimbra ZCS Open Source edition, especially the missing ActiveSync protocol feature I’ve decided to update my mail server to Zimbra Collaboration Suite Network Edition. The upgrade was easy going, just start the ./install.sh script and let it go. The installer asks you for holding the configuration data and after 10-15 minutes my server was running the commercial version with a much better feature set. ActiveSync and mobile devices support are not the only features which I wanted. Also the integrated backup and software updating function was a good enhancement as I see today. I love the software update check which can be configured on a daily, hourly or minutely basis. It will inform you directly when a new release of the collaboration server is available. Great for me because I’m always forgetting to update my services to the newest release.
The good thing is that the update feature is not automatically upgrading your server when a new version is available. You can just configure ZCS to send you an email if a new update is available at the Zimbra website.
Also the backup is great. In the Open Source edition I had to write a script and run a Cron job to backup my server but now, with the Network Edition this is implemented in the admin console. Just selecting the Backup link offers me the option to do a full or an incremental backup of my server.
It’s also possible to do an easy restore for all accounts or just the accounts which have maybe a corrupt database or the users having deleted their data by mistake.
I think Zimbra ZCS Network Edition is a great competition for other collaboration solutions. It’s great that Zimbra can run in either the private or public cloud. If you haven’t seen Zimbra yet, you should definitely check it out at www.zimbra.com.
Running out of memory will prevent the Linux system from running ZCS because it can’t create the needed Java virtual machine and also start essential processes like the MTA. During the installation I came to several situations where I ran out of memory but in the end I could install the software but not start all services. I needed some optimization here. After some searching on the web I found tips which helped me.
Before I go on with the tuning tips for the Vserver I want to give you an overview of the most important command line parameters and log files. For the log files I’ve found a great resource in the Zimbra Wiki. During installation and configuration I’ve needed the zimbra.log which can be found at /var/log/zimbra.log. In this file you’ll find information for MTA, the system status and 3rd party software as Postfix, Amavisd and more. Also interesting is the Tomcat web server log which helped me finding installation errors with the web interface. The information is written in two files: /opt/zimbra/log/mailbox.log and /opt/zimbra/tomcat/logs/catalina.out.
The first command I needed on the server was zmcontrol. With zmcontrol which is located in /opt/zimbra/bin/zmcontrol, you can start and stop services and also get an status.
