How to Provision VMs Using NetApp FlexClones

When properly implemented and configured, VMware Virtual Infrastructure can make provisioning new servers a task that takes only minutes. In fact, in my own lab (running equipment that is, admittedly, several years old and woefully underpowered), I can provision new servers running Windows Server 2003 R2 in less than 10 minutes. That’s pretty impressive.

Viridian Feature Set Trimmed

Microsoft has been hyping up its Windows Hypervisor (“Viridian”) for quite some time now, talking about how the Viridian feature set is going to leapfrog functionality that is currently available on the market. Now, in this article posted this morning, Microsoft has revealed that they have to pull three key features from Viridian in order to meet its delivery schedule.

Dead PowerBook

Back in September of 2003, I made the switch from Windows XP Professional on an HP laptop to Mac OS X (10.2, or “Jaguar”, at the time) on a 15” 1GHz PowerBook G4. Over the next three years, I upgraded the laptop to Panther (using the “Archive and Install” method) and Tiger (using a clean build), and throughout it all the laptop performed without any issues. I used it everyday up until the day I purchased my Core 2 Duo-based MacBook Pro. At that time, I gave the laptop to my daughter to use at college.

HP c-Class Training

I’m in training this week in Canada for the HP c-Class BladeSystem. That means two things: 1) I was unable to attend VMware TSX 2007 in Las Vegas (bummer!), and 2) blog posts may be a bit less frequent than normal. (Of course, I don’t really have a “normal” blog posting routine, but you get the idea.)

VMworld 2007 Proposal Submitted

I just finished submitting my proposal for a VMworld 2007 presentation. When I first came up with the idea for this presentation, I thought it was a great idea, but the more that I worked with it the less enamored I became of it. So instead of the presentation being a “how to” on how to use this specific functionality, it became more of a discussion of advantages versus disadvantages of going down that route. I have no idea how the proposal will be received by the VMworld presentation committee, but I figured I should at least give it a try. After all, the worse that can happen is for them to say No, right?

Solaris 10-AD Integration, Version 3

Thanks to some very helpful individuals in the #solaris channel on irc.freenode.net, I’ve been able to get ADS support working in Samba on Solaris 10, and thus have been able to incorporate the use of Samba in the Solaris 10-AD integration instructions.

SSHjail in Centralized Environments

The idea of chrooting (or jailing) certain security-sensitive services is a well-known and pretty well-accepted method of protecting systems against further compromise in the event of a security breach. BIND is commonly run in a chroot jail, as can be Apache HTTPD or an FTP server. SSH is another common target for running in a chroot jail, and SSHjail is a patch designed to simplify the process of running OpenSSH in a chroot jail. (UNIX die-hards, please forgive me and correct me if I am mistakenly interchanging “chroot” and “jail”.)

Solaris-AD Integration Update Coming

The last update to the Solaris 10-Active Directory integration instructions was in October of last year, over six months ago. Since that time, Sun has released another update to Solaris (Solaris 10 11/06, or Update 3) and I have been able to gather some additional information on using an Active Directory-aware version of Samba to help with the process (much like described in the latest version of the Linux-AD instructions).

Samba in Solaris-AD Integration

Using Samba in Linux-AD integration scenarios is tremendously helpful because it removes the need to manually create the SPNs and export the keytabs out of Active Directory. I wrote up my first test of Samba in Linux-AD integration, then proceeded to verify that procedure and include it in the full Linux-AD integration instructions. But would it work in Solaris-AD integration scenarios?

Mounting SMB Shares in Linux

This is one of those commands that you need to know, but use it so very rarely that it’s hard to memorize. It seems like I have to go back and look this up every time I need to use it. What is it? It’s the command to mount an SMB share from the typical Linux host.
