The results for the Top 25 Virtualization Blogs was just posted a few days ago by Eric Siebert of vSphere-Land.com and I am very proud and honored to announce that virtuallyGhetto has moved up from last year's #8 spot to the #6 spot on the list! I am also very honored that virtuallyGhetto was also voted as the #1 scripting blog! This was quite a surprise to me especially when you are up against guys like Alan Renouf and Luc Dekens.

I also wanted to take this opportunity to thank Eric for all of the time and effort he has put into setting up the site and tallying up all the votes, this is not an easy task. I would also like to thank all of my readers for voting and for your continued support. Finally, I would like to congratulate all the bloggers and give a special shout out to some of the new guys who made the top 25 this year like Michael Webster, Chris Wahl and of course the Storage Guru himself and my good colleague Cormac Hogan! Congratulations guys! I am really humbled to be part of such a talented and passionate community, there is no other like it!

I do not want to spoil the results, so be sure to watch the special vChat results episode and visits Eric's site for the full list.

I recently came across an interesting VMTN thread in which I learned about a neat little feature that allows a user to configure an inactivity timeout for the vSphere C# Client. Once the timeout value has been reached, the vSphere Client will automatically disconnect from the server(vCenter 5.0 or ESXi 5.0 Server). This feature looks to have been introduced with the release of vSphere 5 and was noted in thick-client-timeout guideline in recent release of the vSphere 5 Security Hardening Guide to help reduce the risk of unauthorized access.

There are two methods you can configure the inactivity timeout value:

• Command-line argument to vSphere Client executable
• vSphere Client configuration file (VpxClient.exe.config)

To configure using the command-line argument, locate the vSphere Client executable on your desktop and right click and select properties. You will need to add -inactivityTimeout X, where X is the number of minutes before the vSphere Client will automatically disconnect from the server.

To configure using the vSphere Client configuration file, you will need to locate the VpxClient.exe.config (thanks to user regnak2012 for identifying the required XML entry).

Depending on whether you are running a 32bit or 64bit WindowsOS, they will be located in one of the two places:

• 32bit - %PROGRAMFILES%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher
• 64bit - %PROGRAMFILES(x86)%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher

Next, you will need to right click on VpxClient.exe.config and edit the file using an editor such as notepad. Add the following entry right above the cmdlineFallback, where X is the number of minutes for the timeout value and save then save the file.

To validate that inactivity timeout value works, just connect to either a vCenter Server 5.0 or ESXi 5.0 Server and wait for it to disconnect after the timeout value has been violated. In this example, I configured it for 1 minute and you should see the following screen below once it has disconnected.

Since this feature is client side only, a user can easily change or update this timeout value. One option to guarantee this configuration is by ThinApp-ing your vSphere Client, this way you can control who has access and what the inactivity timeout should be. This can really help when it comes to auditing client side system.

While looking into the vSphere Client options, I also came across a few others that are not documented but might come in handy.

Ignore Certificate - If you have a self-signed SSL certificate when you first connect to an ESX(i) or vCenter Server, you probably have seen the following:

You can automatically ignore this message by specifying the -i command-line option OR add in the VpxClient.exe.config file.

Expand Inventory - If you want to have your entire vSphere inventory automatically expanded out for you each time you login (this may not be a good idea for very large environments) you can specify -expAll command-line option OR add in the VpxClient.exe.config file.

Disable All vSphere Plugins - If you want to prevent any vSphere Plugins from loading, you can specify -noPlugins  command-line option OR add in the VpxClient.exe.config file.
