A simple powershell function

Today, I’d like to share a very simple function I wrote some years ago, I would even say many years :). This is a simple powershell function, without any error handling and parameters checking. I needed at some point to have proper logging of my scripts and I wanted to have it displayed on screen and logged to the file as well for some later usage. I wrote this function to achieve my need.

Powershell : A simple use of DSC

I’m a great PowerShell fan, I think it’s the second best (or maybe first one) thing Microsoft bring to IT world – for me still the one and best is MS Exchange.
Some time ago MS introduced a thing called Desired State Configuration, as I’m correct it was with PS 3.0, for sure with PS 4.0.
You can read a lot of DSC just to google it or go to MS site. I won’t explain how DSC works and what is the pull server, how to enforce configuration compliance, etc …

For my compliance I’m using SCCM, however I found Powershell DSC really useful for my initial server configuration, so I’d like to share how easy and handy is to build some initial server configurations – “Make it smart, make it simpe” – from this starting point one can go wherever … sky is the limit šŸ™‚ Continue reading

How to downlaod files from the web (through proxy) using powershell

Today I had to download around 900 files from ftp server, however firewall was blocking almost everything, however I was able to access the FTP server via web browser (I used one and only IE :)).

So I’d like to present you how easy it is to download the files using powershell (I’m Ā using v.2). Continue reading

Script generating report for DAG replication queues and status on Exchange 2010

When I was working as mail engineer I had to write the script for monitoring CCR queues on Exchange 2007, then my friend had rewritten the script to monitor DAG replication queues on Exchange 2010. So what script does, it generates a html report about the DAG replication queues and sends it via email to defined recipients. There were some tricky parts we’ve had to face, for example there was no possibility to use any open-relay receive connector to send mail, so solution was to create an “eml” file and put it to Exchange “Pickup” folder and it’s a bit tricky to create eml file containing html attachment :).

So command should prepare a csv file with all the users and their properties, even if users are members of nested groups. However a strange error we’ve received.

Getting information about storage in VMWare script

Probably many people had to face such task before me. I had to get information about storage paths in VMWare including the ESX cluster name, hostname, HBA, etc.
I could of course look for a script which was already written, but probably in the same time I was able to write my own script, which was more challanging for me. I’m using PowerCLI cmdlets, so I need at least VMware.VimAutomation.Core pssnapin. So here goes the script. Continue reading

Powershell, not only Microsoft …

PowerCLII reckon, that Powershell is one of the best Mictosoft products. It came alive when Vista/Windows Server 2008 (codename Longhorn – who remembers this šŸ™‚ ) were released. I’m great Powershell fan, it allows to manage many Microsoft products, but not only. Once, I had to change few options in VMWare environment: “Memory/CPU Hotplug” and “Check and upgrade Tools during power cycling” as on screen below

I could do that manually, but changing manually settings in over 5 virtual machines is simply waste of time.Ā  Continue reading
