You know he’s from there because they tend to use too many vowels for some reason.  I like how his article on configuring the license server doesn’t assume much and walks you through the process.If you like working with VMware and PowerShell like I do, be sure to follow his blog.SHARETHIS.addEntry({ title: "How to Configure VMware License Server with PowerShell", url: "http://halr9000.com/article/626" }); No comment 2008-10 9 VI Toolkit (for Windows) Internals, Part 1 In：Powershell, VMware by halr9000 Tags: Powershell,Series,vi toolkit,VI Toolkit Internals,VMware RSJ asked on the VI Toolkit forums, “Get-View and New-Object - how does it work?”. Here’s part one in what probably won’t become a series because if it did, I wouldn’t have time to finish my book! But you never know, I might finish it up. This is the beginnings of a good primer though, so it’s good to have people see it.Cmdlets are the highest level of interface with .NET objects which PowerShell provides. VMware knows more or less what VI admins need to do their jobs. They have a goal of enabling admins by creating cmdlets for as many usage scenarios as they can. Time and money of course are limiting factors, and so version 1 came with a certain set of cmdlets. It was seen that this wasn’t good enough, and that there needed to be a way to access the full SDK to do the low level stuff for which they did not yet have time to fill out with cmdlets. Thus, Get-View.Get-View deals with server-side objects represented by the VI web service (and documented in the SDK). With it, you can do anything that the VI Client can do, and more. It’s more complicated to use, of course, and in fact, it’s not a lot simpler than writing a "full" program using a language like C#. But it’s not bad, relatively speaking.You can pass several different kinds of "automation objects", those which live in your PowerShell session, to Get-View and voila, you now have a new object which has a richer set of methods and properties. However, this only works for "managed objects" (and not directly for all of them), which are only one type of object represented in the SDK. This leaves "data objects" totally left out, and they are important, too.New-Object has nothing to do with the VI Toolkit, it’s a cmdlet which comes with PowerShell. Its used to give you the ability to access a .NET (or COM) object which is stored in an assembly (fancy name for a DLL). One thing you can do with it is to create these data objects. The data objects are often used as specifications to methods. This basically works like a giant bundle of arguments to perform a single action.SHARETHIS.addEntry({ title: "VI Toolkit (for Windows) Internals, Part 1", url: "http://halr9000.com/article/625" }); Only 1 comment 2008-10 4 VI Toolkit One Liner: Get all VirtualCenter Logs In：Powershell, VMware by halr9000 Tags: Powershell,Series,VI Toolkit One-Liner,VMware This will grab the contents of all of the log files on your VirtualCenter server. Normally there will be eleven of them: logs zero through nine are rotated through at each service startup, and the index umm, I forget what’s in it. Anyway, here you go:$log = Get-LogType | ? { $_.key -match "vpxd" } | % { Get-Log -Key $_.Key }You may have to be patient. This took 175 seconds to run on my box.And here’s how to get at the contents:PS > $log[0].Entries | select -first 10Log for VMware VirtualCenter, pid=1484, version=2.5.0, build=build-104215, option=Release, section=2[2008-10-04 09:36:07.703 'App' 268 info] Current working directory: C:\WINDOWS\system32[2008-10-04 09:36:07.703 'Libs' 268 info] HOSTINFO: Seeing Intel CPU, numCoresPerCPU 1 numThreadsPerCore 2.[2008-10-04 09:36:07.703 'Libs' 268 info] HOSTINFO: This machine has 1 physical CPUS, 1 totalcores, and 2 logical CPUs.[2008-10-04 09:36:07.703 'App' 268 info] Log path: C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\Logs[2008-10-04 09:36:07.703 'App' 268 info] Initializing SSL[2008-10-04 09:36:08.093 'Libs' 268 info] Using system libcrypto, version 90709F[2008-10-04 09:36:17.109 'App' 268 info] Vmacore::InitSSL: doVersionCheck = true, handshakeTimeoutUs = 30000000[2008-10-04 09:36:17.343 'App' 268 info] Starting VMware VirtualCenter 2.5.0 build-104215[2008-10-04 09:36:17.453 'App' 268 info] Log directory: C:\Documents and Settings\Default User\Local Settings\Application Data\VMware\vpx.SHARETHIS.addEntry({ title: "VI Toolkit One Liner: Get all VirtualCenter Logs", url: "http://halr9000.com/article/624" }); No comment 2008-10 2 Solving Problems with PowerShell: Add global groups to local groups with ADSI In：Powershell by halr9000 Tags: Powershell,Series,Solving Problems @Phactotum writes:I have a list of servers and groups, and I need to add the domain group to the servers local administrators group. I figured out if I do the following I can do a single server group combo:([ADSI]"WinNT://Server/Administrators,group").add("WinNT://Domain/Group,group")And I found that I can use import-csv to show me my CSV file. I just can’t figure out how to get the server name and group name plugged into the command I want to run.I thought this was a good question so I figured I’d address it here. The first thought I had when I saw this was, “Whew! I don’t have to come up with the ADSI code”. That particular API is horribly picky and the objects it returns are quite awkward to use. Jeffrey Hicks has seemed to make good use of them, I think he may know something I don’t. Anyway, my solution to the problem involves what is probably lesser-known feature of PowerShell called named scriptblocks. Ther’es three of them, Begin{}, Process{}, and End{}. Here’s the script:Process { $Server = $_.Server $Group = $_.Group ([ADSI]"WinNT://$Server/Administrators,group").add("WinNT://Domain/$Group,group")}So you would save this as a script (or put it into a function) and call it like this:Import-Csv file.csv | .\Modify-LocalGroups.ps1So this is an elegant and easy to read way to solve the problem. An alternate way would involve making a foreach-object loop and do everything inside the script. I like using the named script blocks though because that allows you to keep the input separate from the working part of the script.SHARETHIS.addEntry({ title: "Solving Problems with PowerShell: Add global groups to local groups with ADSI", url: "http://halr9000.com/article/623" }); 5 Comments 2008-10 2 PowerShell Script: DHCP Renewal Alert In：Powershell by halr9000 Tags: dhcp,network,Powershell,script,wmi get-wmiobject,write-host There was a problem with the network in the office this morning. Rather than sit there staring at the screen, I decided to write a script that would let me know when things were back up. In my case, the indicator would be when the DHCP server gave me an IP, because that was the primary symptom—no IP.Here’s the script. You will have to modify the Get-WMIObject query results to point to your NIC as that will vary per computer.$nic = gwmi Win32_NetworkAdapterConfiguration | ? { $_.IPEnabled }while ( $retval -ne 0 ) { $retval = ($nic[0].RenewDHCPLease()).ReturnValue}Write-Host `a`aIn case you haven’t tried it, “`a” is the escape code for BELL which causes your internal PC speaker to go beep. This is really loud on many computers. Also, “?” here is a built-in alias to the Where-Object cmdlet.SHARETHIS.addEntry({ title: "PowerShell Script: DHCP Renewal Alert", url: "http://halr9000.com/article/622" }); 2 Comments 2008-10 2 New Microsoft Most Valued Professional In：Powershell, asides by halr9000 Tags:  I’m very thrilled to announce that Microsoft and the MVP community have accepted me into their ranks under the Admin Framework category.

In：Powershell, VMware by halr9000 Tags: If you do, then drop everything and go check out the website of Hugo Peeters. I had subscribed to his blog some months ago but then got behind on all of my blog reading due to my book project. I had a spare moment today to scan some feeds and I learned that Hugo has been putting out an incredible number of example scripts. I like to put script samples out there myself, and I’ve done so on my blog, but its really hard for me to find the time lately to do so. It’s really great to see that Hugo has the time, because he’s really contributing the community in a big way.Here are some sample posts that caught my eye:Virtual Center Server Settings revealed by PowershellSet-SoftPowerOffGetting Started with the VMware Update Manager Powershell Snap-InThanks, Hugo!SHARETHIS.addEntry({ title: "Need More PowerShell VMware Scripts?", url: "http://halr9000.com/article/620" }); No comment 2008-9 27 Pandora needs your help right NOW! In：Internet, Music by halr9000 Tags:  [pasted from a Facebook update I received 9/27/08 at 9:55pm]Dear Pandora fans -We urgently need your help! We need you to make a phone call to support internet radio.After a yearlong negotiation, Pandora, SoundExchange and the RIAA are finally optimistic about reaching an agreement on royalties that would save Pandora and internet radio. But just as we’ve gotten close, large traditional broadcast radio companies have launched a lobbying campaign to sabotage our progress.Yesterday, Congressman Jay Inslee, and several co-sponsors, introduced legislation to give us the extra time we need but the National Association of Broadcasters (NAB), which represents radio broadcasters such as Clear Channel, has begun intensively pressuring lawmakers to kill the bill. We have just a day or two to keep this from collapsing.This is a blatant attempt by large radio companies to suffocate the webcasting industry that is just beginning to offer an alternative to their monopoly of the airwaves.Please call your Congressperson right now.Call 202-225-3121 and ask for your representative.Ask them to support H.R. 7084, the Webcaster Settlement Act of 2008. Congress is currently working extended hours, so even calls this evening and over the weekend should get answered.Thanks so much for your continued support!Tim, and the whole Pandora staffSHARETHIS.addEntry({ title: "Pandora needs your help right NOW!", url: "http://halr9000.com/article/618" }); No comment 2008-9 27 PowerShell Script: WhileTimeout In：Scripting by halr9000 Tags: function,library,Powershell,script,tips,while This script is a generic wrapper for the While statement that will execute a condition a given number of max tries, waiting a given number of seconds in between.This example will execute the “IsItDoneYet” function (that checks a hypothetical external factor) once every 5 seconds, a total of no more than 24 times, which will take approximately two minutes, not including function execution time.PS > $condition = { IsItDoneYet }PS > WhileTimeout 5 24 $condition download | new postSHARETHIS.addEntry({ title: "PowerShell Script: WhileTimeout", url: "http://halr9000.com/article/615" }); No comment Next Page »  Subscribe in a reader
