How to install Visual Studio Code on Linux Mint 18

I have wrote about the installation of PowerShell Core in Linux Mint 18 yesterday. Today, I want to show you, how to install Visual Studio Code on Linux Mint 18. The installation is really easy:

  1. Download the deb package
  2. Install the deb package
  3. Run Visual Studio Code

You can download the latest packages for Windows, Linux (deb and rpm, if you want even a tar ball), and Mac on the Visual Studio Code download page. Download the deb file. To install the package, open a Terminal window and run dpkg .

sudo  might ask you for a password. That’s it! Now you can simply start VS Code.After you have installed your favorite extensions, VS Code is ready to code. read more

How to install PowerShell Core on Linux Mint 18

Beside my Lenovo X250, which is my primary working machine, I’m using a HP ProBook 6450b. This was my primary working machine from 2010 until 2013. With a 128 GB SSD, 8 GB RAM and the Intel i5 M 450 CPU, it is still a pretty usable machine. I used it mainly during projects, when I needed a second laptop (or the PC Express card with the serial port…). It was running Windows 10, until I decided to try Linux MInt. I used Linux as my primary desktop OS more than a decade ago. It was quite productive, but especially with laptops, there were many things that does not worked out of the box. read more

Continuity vs. change

Note: I trashed this blog post several times. But I would like to express my point of view (hey, this is my blog. :D )

Some weeks back, I had an interesting discussion with a HR consultant. Bottom line: You ruin your career, if you stay for more than 3 years at the same company. IMHO this is bullshit.

I have started my IT career, right after school, with an apprenticeship at a local IT company. I finished this apprenticeship three years later, and my employer offered me a position as IT-Technician. Until 2004, I changed my employer three times. There were good reasons for each change. I learned pretty much in these years. The last change took me to my current employer. I have started as a Technical Consultant in October 2004. Today, thirteen years later, I’m leading the consulting and services business unit. There is a good chance I will not leave this company until retirement. At least not for the same or similar job role. read more

Notes about 802.1x and MAC authentication

Open network ports in offices, waiting rooms and entrance halls make me curious. Sometimes I  want to plugin a network cable, just to see if I get an IP address. I know many companies that does not care about network access control. Anybody can plugin any device to the network. When talking with customers about network access control, or port security, I often hear their complains about complexity. It’s too complex to implement, to hard to administrate. But it is not sooo complex. In the easiest setup (with mac authentication), you need a switch, that can act as authenticator, and a authentication server. But IEEE 802.1x is not much more complicated. read more

NetScaler ADC – Hidden vServer for HTTPS redirect

Starting with release 11.1, NetScaler ADC offers an easy way to redirect traffic from HTTP to HTTPS within the configuration of a load-balanced vServer. With 11.1, Citrix introduced the paramter  -redirectFromPort and -redirectURL.

While playing with a NetScaler ADC in my lab, I discovered a strange error message as I tried to configure the redirect.

Internal vserver couldn’t be set?! Okay, there was already a vServer, that was listening on port 80. After removing the vServer, I was able to setup the redirection and it was working as expected. read more

Workaround for broken Windows 10 Start Menus with floating desktops

Last month, I wrote about a very annoying issue, that I discovered during a Windows 10 VDI deployment: Roaming of the AppData\Local folder breaks the Start Menu of Windows 10 Enterprise (Roaming of AppData\Local breaks Windows 10 Start Menu). During research, I stumbled over dozens of threads about this issue.

Today, after hours and hours of testing, troubleshooting and reading, I might have found a solution.

The environment

Currently I don’t know if this is a workaround, a weird hack, or no solution at all. Maybe it was luck that none of my 2074203423 logins at different linked-clones resulted in a broken start menu. The customer is running: read more

Some thoughts about using Windows Server 2012 R2 instead of Windows 10 for VDI

Disclaimer: The information from this blog post is provided on an “AS IS” basis, without warranties, both express and implied.

Last week, I had an interesting discussion with a customer. Some months back, the customer has decided to kick-off a PoC for a VMware Horizon View based virtual desktop infrastructure (VDI). He is currently using fat-clients with Windows 8.1, and the new environment should run on Windows 10 Enterprise. Last week, we discussed the idea of using Windows Server 2012 R2 as desktop OS.

Horizon View with Windows Server as desktop OS?

My customer has planned to use VMware Horizon View. The latest release is VMware Horizon View 7.2. VMware KB article 2150295 (Supported Guest Operating Systems for Horizon Agent and Remote Experience) lists all supported (non-Windows 10) Microsoft operating systems for different Horizon VIew releases. This article  shows, that Windows Server 2012 R2 (Standard and Datacenter) are both supported with all Horizon View releases, starting with Horizon View 7.0. The installation of a View Agent is supported, and you can create full- and linked-clone desktop pools. But there is also another important KB article: 2150305 (Feature Support Matrix for Horizon Agent). This article lists all available features, and whether they are compatible with a specific OS or not. According to this artice, the read more

Data Protector Exchange GRE and IP-less Exchange DAG

When dealing with Microsoft Exchange restore requests, you will come across three different restore situations:

  • a database
  • a single mailbox
  • a single mailbox item (mail, calendar entry etc.)

Restoring a complete database is not a complicated task, but restoring a single mailbox, or a single mailbox item, is. First, you need to restore the mailbox, that includes the desired mailbox, into a recovery database. Then you can restore the mailbox, or the mailbox items, from the recovery database. Some of the tasks can only be done with the Exchange Management Shell.

The HPE Data Protector Granular Recovery Extension (GRE) for Microsoft Exchange helps you to simplify the necessary steps to recover a single mailbox, or mailbox items. But the GRE can only assist you during the restore. It hids the above described tasks behind a nice GUI. The backup of Microsoft Exchange is still something you have to do with HPE Data Protector. read more

Why “Patch Tuesday” is only every four weeks – or never

Today, this tweet caught my attention.

Patch management is currently a hot topic, primarily because of the latest ransomware attacks.

After appearance of WannaCry, one of my older blog posts got unfamiliar attention: WSUS on Windows 2012 (R2) and KB3159706 – WSUS console fails to connect. Why? My guess: Many admins started updating their Windows servers after appearance of WannaCry. Nearly a year after Microsoft has published KB3159706, their WSUS servers ran into this issue. read more

Roaming of AppData\Local breaks Windows 10 Start Menu

One of my customers has started a project to create a Windows 10 Enterprise (LTSB 2016) master for their VMware Horizon View environment. Beside the fact (okay, it is more a personal feeling), that Windows 10 is a real PITA for VDI, I noticed an interesting issue during tests.

The issue

For convenience, I adopted some settings of the current Persona Management GPO for Windows 7 for the new Windows 10 environment. During the tests, the customer and I noticed a strange behaviour: After login, the start menu won’t open. The only solution was to logoff and delete the persona folder (most folders are redirected using native Folder Redirections, not the redirection feature of the View Persona Management). While debugging this issue, I found this error in the eventlog.

If you google this, you will find many, many threads about this. Most solutions describe, that you have to delete the profile due to wrong permissions on profile folders and/ or registry hives. I used Microsofts Procmon to verify this, but I was unable to confirm that. After further investigations, I found hints, that the TileDataLayer database could be the problem. The database is located in AppData\Local\TileDataLayer\Database and stores the installed apps, programs, and tiles for the Start Menu. AFAIK it also includes the Start Menu layout. read more
