AWS Assume role [Powershell]

Sun, 03 Apr 2016 14:12:05 +0000

This is a handy 2 lines Powershell script to assume a role in AWS, create temporary credentials and run another command using the assumed roles:

$Response = (Use-STSRole -Region eu-west-1 -RoleArn arn:aws:iam::<accountID>:role/<RoleName> -RoleSessionName RoleSession1).Credentials

$Credentials = New-AWSCredentials -AccessKey $Response.AccessKeyId -SecretKey $Response.SecretAccessKey -SessionToken $Response.SessionToken

Get-S3Bucket -BucketName yourbucketnamehere -Credential $Credentials

Exporting unexportable certificates

Sat, 25 Apr 2015 21:32:22 +0000

You sometimes run into cases where a certificate was imported by another sysadmin and he forgot to check the option to export the private key. If you want to export the certificate together with the private key the option would be greyed out.

Unless you have access to the original certificate there is no Windows built-in method to retrieve the certificate. Mimikatz is a nice program that hooks into the Windows NT APIs and allows you to export unexportable certificate.

Google Apps certified!

Sun, 28 Aug 2011 16:27:05 +0000

This week was an exceptional good week, but the the most important accomplishment is that I managed to pass my Google Apps certification exam and I’m now a Google Apps Certified Deployment Specialist.

It was now a matter of pride passing this exam, having been sponsored by a 3rd party who I hope will use my skills in the future.

ITCamp 2011

Mon, 30 May 2011 23:22:53 +0000

Last week I attended ITCamp 2011 a premium conference held in Cluj-Napoca and organized by 2 communities: ITSpark and CodeCamp. Now that I have a bit more time off, I decided to write about my experience.

The first thing that comes to mind is finally! While I like small community events with 20-30 participants, a big event like ITCamp was long overdue. I remember the last TechNet session I attended in Cluj was quite a while ago, in 2007.

Connection Day – Cluj-Napoca

Tue, 05 Apr 2011 00:02:08 +0000

Tomorrow I will be hosting a presentation and a workshop with fellow ITSpark members Chris, Cosmin and Tudy.

As Tudy has already blogged, the event is part of a 3 cities road-trip (Cluj-Napoca, Bucharest and Timisoara), a series of events held under the auspices of Microsoft with the goal of bringing NGO and IT closer, so they can work and solve problems easier.

Strange errors in SCCM 2007

Wed, 05 Jan 2011 13:42:49 +0000

Right after New Years Eve I had to update some packages/advertisements for some new software. That was easy, but the problem was that none of the clients got the advertisements.

I started to troubleshoot the problem and looked at the ConfigMgr Site Status. There I got some really nasty errors one for the MP Control Manager component and another for the MCS Control Manager.

MP Control Manager detected management point is not responding to HTTP requests. The HTTP status code and text is 400, Bad Request.
