The default behavior of a Windows Server NT4 through 2008 based domain is to allow a Domain Admin account to manage Windows clients. A number of environments have been moving over to using the PDC emulator on Mac OS X as a means of replacing aging Windows servers. One of the biggest annoyances is that the Open Directory administrative accounts they use to bind the Windows computers to are not local administrators. When you bind Mac OS X to Active Directory you can specify which Active Directory groups are administrators of Mac OS X client systems so you would imagine you can do the same thing on an OS X…

Looking at Google Android's Internals
Google’s Android is a very small Linux distribution. Recently I needed to test some applications that were developed by a couple of friends of mine. Rather than run out to T-Mobile I figured I’d just install the new LiveAndroid disk and thought I would write up how to get setup using VMware Fusion and then go about doing some tasks with Android. To get started make sure you’re running the latest Fusion (or Parallels or Q or VirtualBox). Then download two ISO files from http://code.google.com/p/live-android/ liveandroidv0.2.iso.001 and liveandroidv0.2.iso.002. Once you have downloaded the two ISO files we’re going to need to join them. To do so cat liveandroidv0.2.iso.001 liveandroidv0.2.iso.002 >…

OpenSolaris 2009.06 First Impressions
OpenSolaris 2009.06 is the next generation of the OpenSolaris, the Open Source Solaris that has become the testing ground for new features bound for Sun’s popular Solaris Operating System. The latest version of OpenSolaris sports a number of new features that environments both large and small are sure to find interesting, most of which have to do with more streamlined ways of managing disk, network and other resources – both in virtualization environments and with the operating system itself. First up is package management (using the tool appropriately called Package Manager). It’s now easier to install software managed/compiled by the OpenSolaris community. The packaging environment for OpenSolaris can now access…

Using the arp Command
You can delete an IP address from the arp table using the arp command along with the -d option followed by an address. For example, to delete IP 10.10.10.1: arp -d 10.10.10.1 If you’re not sure which IP address you’re looking for then you can look at the arp table to check the IP against the MAC address by using the -a option along with arp. For example: arp -a To delete all of the entries in an arp table (they do regenerate after all) you can use the -d option in conjunction with the -a option: arp -d -a If you then want to manually add an entry into…

Disable NetApp FlexClone Snapshots
When you create a FlexClone, you will automatically enable scheduled snapshots. These can be disabled using the same command (snap) that you used to set them up. The snap command comes with a sched option, which if you want to disable for a specific LUN you would follow up with the name of the LUN and then a ‘0’. For example: snap sched fvolclone 0 If you are using your NetApp for Xsan LUNs then the snapshots are pretty much useless anyway…

Disable and Remove .DS_Store Files
In a number of environments, where SMB, AFP and other file sharing protocols are used with Mac OS X, Windows and Linux clients, there are a number of hidden files that Mac OS X leaves behind. For anyone who has managed an environment like this you’re likely to notice the .DS_Store files and potentially even have tried taking measures to get rid of them. However, try as you might they’re likely to have come back repeatedly. But you don’t have to live with them. You can tell your Windows clients not to show hidden files. From Windows XP, open an explorer.exe window (Windows Explorer, also accessible by browsing any folder…

S3 Command Line Part II
Earlier we looked at using s3cmd to interact with the Amazon S3 storage cloud. Now we’re going to delve into using Another S3 Bash Interface. To get started, first download the scripts and then copy the hmac and s3 commands into the ec2 folder created in previous walkthroughs. To use the s3 script, you need to store your Amazon secret key in a text file and set two environment variables. The INSTALL file included with the package has all the details. The only tricky part I ran into, and from the comments on Amazon, other people ran into, is how to create the secret key text file. Now go into your…

Amazon S3 from the Command Line
In a previous article we looked at how to upload Final Cut Server content to s3 using Jungle Disk. We also looked at how to upload ec2 images to s3. But now we’re going to take a deeper dive into using s3 from the command line. There are a number of tools that have been developed by the community to leverage Amazon’s S3 Storage Service. This isn’t as cut and dry as using ec2 due to the fact that the Amazon tools are written in Java, C#, Perl, PHP, Ruby and Python. However, I’m a shell kinda’ guy to a large degree and I was able to find a couple of places where people have written…

Custom VMs using S3+EC2
I’m obviously enjoying using Amazon for a number of testing applications (in addition to of course buying books and light bulbs from them, and not one showed up broken). So far, I’ve done articles on getting started with Amazon ec2, using the command line with ec2, whitelisting an IP address, deploying ec2 en masse, and setting up a static IP for ec2. But the S3 articles have been sparse. So, now let’s look at using Amazon’s storage service (S3) from the command line. Funny enough, if you’re going to upload your own custom Amazon Machine Instances (AMIs) you’ll need to leverage S3. When you go to bundle an image, you will have a…
