How to escape geoblocking by content providers with Squid

Have you ever encountered content that was “not available in your region” while surfing the web?

Have you ever wanted to watch one of the shows that Netflix has available in another country?

I bet you have, especially if you live outside the United States of America. The solution to this issue is easy enough: you can use a proxy server or VPN service. But there are two issues with that approach:

  • All your internet traffic is going through the VPN. If this can result in very notable delays when surfing your normal websites.
  • You usually have no insight into what kind of logging you VPN provider does. So you really shouldn’t do any sensitive stuff over that connection.

Ideally you would want all of your normal surfing to go out through your normal internet connection and all the region specific stuff through a VPN or some other proxy.
And you can actually build something to do this with Squid. Squid is an Open Source proxy server.

A proxy Server sits between your browser and the websites you want to surf to. It accepts all your requests to surf to certain websites and processes them according to its configuration. Once it has determined that the request is valid, it will contact the web server for you and fetch the content you want. It will then forward it to your browser.
Since it sits in the middle of your traffic, it is the perfect place to redirect some traffic through another connection.

This diagram visualizes the difference between the two options for you:

And this is really just the start of your capabilities of Squid. While this tutorial will only show you a few basics of squid and how you can redirect some content over a VPN or another Squid server, there is so much more that can be done with Squid:

  • Are you on a connection with a fairly low Volume available (like some mobile contracts)?
    No problem! Just crank up the caching in squid and repeated visits of the same website won’t be as demanding on your volume.
  • Have kids that that visit bad websites?
    No problem! You can use squid to filter the internet by pretty much any criteria your want. And you can do it on a per user or computer basis if you need to.
  • You hate ads on websites, but maintaining you Ad-Blockers across all devices is annoying?
    No worries! You can use squid as your Ad-Filter.

Why the Star Citizen Demo at Gamescom had to happen the way it did

Star Citizen GlaiveThere has been quite a bit of critique towards Star Citizen lately. Some of that even swapped over into the mainstream tech news here in Germany.
On the other hand I have been told by quite a few people that they read gaming news and they no idea about some of the new features of the game.
Especially the Gamescom multi crew demo was something a lot of people were unaware of. Continue reading Why the Star Citizen Demo at Gamescom had to happen the way it did

What is worth the wait at Gamescom 2015

The Gamescom just opened today and I was able to get a wild card ticket to get in for half a day during the press day. Overall it was very nice since the wait for the shows was bearable today.

If you are headed to the Gamescom this year, you might wonder what could be worth standing in line for. I was not able to see everything but here are my top picks from the stuff that I did see:

Fallout 4

It was one of the main reasons I went to Gamescom this year. The game itself looks great. That being said I am somewhat skeptical about how they present the S.P.E.C.I.A.L and the Perk system.

Also I would prefer it if they involved Obsidian in Fallout 4. New Vegas was just so much more awesome than Fallout 3.

The Booth looked quite impressive on the outside:Fallout_4_Booth_outside

And they even decorated the inside of their cinema, which is quite unusual:Fallout_4_Booth_inside

Deus Ex Humanity Divided:

The game looks very interesting and the show has quite a bit of game play in it. The gist is It is a lot like the last part of the series but they did improve combat quite a bit. Also there is bribery going on: For visiting the show you get one of these:Deus_Ex_Figurine


I love the x-com games so I am biased here, but you get a glimpse of the strategic game play that was not shown during the E3.
The new mobile Headquarter seems like it could bring some fresh new ideas to XCOM without disrupting to core game play.

You should have a look yourself and since this is a PC only games the lines should not be too long


Other things to check out:

VR is a huge topic this year and you can test quite a few different VR solutions. I tested the Occulus last year and it was quite fun. So if you have never tested VR goggles you should take this chance to get an impression of the technology.
While VR is great and will add a lot towards the imersion in gaming. It’s probably best to wait till all the big name companies release their VR products and then pick the one that is best supported by all the games. On PC that might end up being the HTC VR Googles since they are backed by Valve.

If you are interested in RPGs and have yet to play Pillars of Eternity, there are two computers where you can test it in the Paradox booth in hall 9. You will probably love it and they will have to involve security to remove you from the computer but it’s well worth it trust me.
Unfortunately there wasn’t anything about the upcoming addon.

Another very promising Kickstarter game that you might want to check out is Kingdom Come: Deliverance. They have a small Booth in the indie area in hall 10.

Elite Dangerous has quite a big presence and a very cool booth:Elite_Dangerous_Booth

It’s also supposed to be a great game to hold you over till Star Citizen releases fully. It’s on my to buy list at least.

Last but not least, there is a small handheld SteamMachine presented right next to the HTC/Steam VR Googles.It is called Smach Zero and it’s worth to keep an eye out for this.

I had a little chat with the team there and if they can keep their promises this would be a very cool gadget.
It is a small handheld device running Steam OS and supposedly able to play all SteamOS games at 720p offline(so no streaming) on the go.
It will also be able to connect to a TV via HDMI and have Bluetooth to connect peripherals.

I don’t usually do Mobile gaming but with the kind of horsepower needed for 720p gaming and the size it has, it could make a really great Media Center client. And since SteamOS is just Linux, it will probably not be very hard to get the needed software running.
And they aim to release it for 299EUR which is fairly affordable.

I forgot to take pictures of the booth, but here is the flyer if you are interested:

Edit: It seems like Star Citizen has a Booth now in hall 10.1. Go check it out. I still don’t like that I did not get to see it, but no reason for you to miss out.
They are also Listed in the Gamescom app now, so I guess they just skipped the press day.


Every Year there is a few Games that disappoint by not showing up or just putting no effort into it. Those are my picks this year.

Total War: Warhammer

Their Booth looked so promising:Total_War_Warhammer_Booth

But what they did show was only this video

One of they staff was commenting it live, but If you follow the game you know this already. If you don’t know it already, its worth watching though. Especially since their cinema is public, so you won’t have to wait.

Wasteland 2 was missing

I was not able to find Wasteland 2. Maybe they show it only in the business area or they show a video on the Deepsilver main stage during the other days. But I was hoping to get my hands on the new and improved Wasteland 2 already.

If you go to Gamescom tell me your favorite


The shocking Truth about the current state of your Data: How to built a fully encrypted file server with ZFS and Linux to avoid data loss and corruption

Do you know if all the Data on your File Server is OK?

Unless you are already using ZFS, Btrfs or ReFS you don’t. If your file server is a couple of years old, there is a very good chance that your Data is NOT OK.

Your server hardware might tell you everything is OK but that does not really tell you much because none of your monitoring systems check the actual data.

ZFS on the other had knows if your data is ok and can even repair it. I upgraded my file server recently. All the old disks that were still in the pool at the time were OK according to their SMART values. yet look what the monthly check told me:Scrub results of my Old Server almost 2 MB of Data had to be repaired. Just think about that: In just one month almost 2MB of data got corrupted. And right now you don’t know if your server has similar issues. If you did not know it yet this particular issue has a name: Bit Rot and it gets worse the older your current hardware is and more likely the larger your disks are.
You might not realise it but 2MB is a lot of data. It can be an important document or picture. Or it can be that it is just 2MB of a huge CAD file that is totally unreadable without those 2MB.
Granted my old server is quite a bit of an extreme example because I postponed the upgrade quite a bit longer than I originally wanted to. And the disks in it were not meant for this workload.

But I have seen quite a few that storage servers or NAS boxes remained almost untouched until a disk failed or they were full. So old hardware is not all that uncommon, especially at home and in the SMB market.

Now you might think setting up a new file server is easy right? You could just take Server 2012 with ReFS and Storage pools and be done with it.

Technically that is correct, but even in Windows there is really quite a bit more to consider. That being said I want to make the case for Open Source because for this purpose it is simply better than Windows.
In particular I want to show you how to build your file server with ZFS and Linux, two proven Open Source technologies. When you are done the Server will integrate nicely into your windows environment. Your users will not know the difference and you don’t have to get headaches from trying to license Windows correctly.

How to eliminate spam and protect your name with DMARC

 If you are reading this you are probably making my life harder

E-Mail sucks! Your users just keep clicking the links in those damn phishing mails. And you can’t do anything about it. Hell somebody might be sending spam in your name and you have no idea about it. Let me blow your mind: You can solve these problems, for free. And I will introduce you the tools you need.

The cure to your E-Mail headaches hides behind three small acronyms:

  • SPF: Sender Policy framework, tells others which mail servers are authorized to send E-Mail for your domain.
  • DKIM: Domain Keys Identified Mail, uses encryption and DNS to verify an E-Mail sender and that it was not altered in transit
  • DMARC: Domain based Message Authentication, Reporting and Conformance. Builds on SPF and DKIM and implements a policy and reporting system around them

Setting up an Active Directory authenticated Mumble Server

Basic Setup

Setting up a Mumble server is fairly simple, but I had a few problems to get it to play nice with my Active Directory. And since there wasn’t exactly a great deal of documentation on the subject, I figured that I should write a short How To. Continue reading Setting up an Active Directory authenticated Mumble Server

Rescuing Data from a Buffalo Link Station with failed a RAID

Recently I was confronted with a Buffalo LinkStation which had a failed RAID0. The data on it was important, and the customer did not have any current backups. The were a lot of huge red flag warning signs that seemed to suggest a disk possibly going bad, but the the guy at the customers location that doubled as IT happily ignored those. Buffalos willingness to support this problem extended to replacing bad hard disks, since all data on a failed RAID0 is considered irrecoverably lost by them. That was not entirely unexpected to hear of a tier one support worker though.
I did a little digging and found out, that those LinkStations use some fairly common tools under the hood. So I agreed to have a look, but made it clear that I might not be able to get anything back. The customer wanted me to try anyway and I got a good amount of the data back. The Article describes how. Continue reading Rescuing Data from a Buffalo Link Station with failed a RAID

How to reset a lost password for your only Windows Domain Admin

The Problem

A while ago somebody came to me with a problem. A bunch of Services on their Server stopped working. The admin password in the documentation didn’t work. The Server in question was a SBS with a bunch of additional software that was critical to the business. My questions for Backups were answered with silence.

Continue reading How to reset a lost password for your only Windows Domain Admin claims the rights to the word “Saga” in Video Game Titles

I apologize in advance about this rant, but I need to get this off my chest.

I seriously hope this is a bad joke. But from this fairly convincing forum post it seems like not only claims this word to be its trademark.

It looks like they want to sue Stoic Studios for infringing on this trademark with their really great game The Banner Saga. Continue reading claims the rights to the word “Saga” in Video Game Titles
