how to feed your g-apps mailbox with archived mails…

July 23rd, 2009

one of the greatest features of a g-apps mailbox is the google-email-uploader (with a free gmail-account that doesn’t work). with this tool you can upload all your mail-archives – you just need a running Outlook2003+ installation and your old archives (pst-files) attached to it. Then close Outlook and start the tool – after you have choosen whether you want it to create labels from the foldernames or just archive all the imported emails, it will look like this:

but don’t forget to do a backup of all your emails somewhere else – you’ll never know ;-)

saving energy with windows7 in vdi

July 21st, 2009

[For the german/original version - please click here.]

After the release of vSphere the VMware Distributed Power Management feature (DPM) [1] has left “experimental” state – so you can achieve real power savings in optimized Virtual Desktop Infrastructures now. With Windows7, which is to be released on 22nd of october 2009 [2], you get one more cool tool to throttle power consumption in your it-infrastructure:The Power Efficiency Diagnostics Report can be automatically created through a little command in a Windows7 CLI with administrative rights.

After starting the command powercfg -energy the system is monitored for 60 seconds and at the end the results are written down in a file called energy-report.html.

This report has some useful information for customizing your golden image of your vdi in terms of power consumption. Information you will get are:

  • usb-devices which doesn’t turn into standby-mode (not interesting for vdi)
  • processes with a high cpu utilization
  • settings of your energy-management

In big environments there is a good possibility, that there can be big energy savings achieved by optimizing physical windows7 workstations with this tool as well.

SmartAccess in real world scenarios…

July 14th, 2009

[For the german/original version - please click here.]

Because many of our customers do not really know what SmartAccess could do for them, i’ll describe some real world use-cases here:

Citrix SmartAccess needs the following components to work:

  • Citrix Access Gateway Advanced or Enterprise Edition
  • Citrix Webinterface 5.x
  • Citrix XenApp 4.x or higher

And it can do the following functions for you:

  • constrain published applications by result of endpoint analysis
  • switch off ica-features (for example file-transfer, printing or clipboard) by result of endpoint analysis
  • secure ssl-vpn access by result of endpoint analysis

These functions allow you to implement a secure and flexible access to your network. So the mobile users will win flexibility + productivity without compromising the security of your network. In the following figure you can see an example use-case with CAG as ica-proxy and endpoint analysis.

In this scenario the state of the antivirus client and the state of the windows firewall is checked. Citrix is delivering some so called expressions for some av-clients and a few personal firewalls but mostly you have to configure these expressions to your own needs. Therefor you can use timestamps of files, the state of services and processes and network-parameter like mac-
addresses.
The second scenario uses the same expressions but decides between ica-proxy and the more powerful ssl-vpn access.

Therefor the result of the enpoint analysis is only beeing interpreted at the CAG itself – It’s not interpreted at the XenApp-Server, like it is done in the scenario before. So the CAG itself just decides wether the user can use ica-proxy only or a more powerful ssl-vpn-connection.

The combination of the two scenarios could lead to the following scenario:

Furthermore you can use SmartAccess in combination with XenDesktop as well.
