When I wrote my 3 part overview of LTE-A Pro for Public Safety Services back in January this year I wasn’t aware that just a couple of weeks earlier the UK government has given out a contract to build a 4G Public Safety Services network that, from what I read between the lines, will be piggybacked onto EE’s (soon BT’s) commercial LTE network.

2nd Hand Computing
Ever thought about buying a 2nd-hand notebook? Me neither until recently when a friend asked for advice. At first I was quite skeptical but it turns out it’s an interesting option and in the meantime I even bought one for myself.
IPv6 When Tethering
Just because a smartphone can get an IPv6 address from a cellular network doesn’t necessarily mean that its tethering functionality is also IPv6 capable. Fortunately, I’ve noticed in practice that more and more devices that are coming to the market these days have implemented the feature. And here is how it works:
Making A Good Backup Strategy Even Better – Instant Usability
Over the years, my backup strategy with Clonezilla and Lucky Backup have helped me quite a number of times, especially back in January when a notebook under my care was stolen while traveling. With my backup strategy it takes around 30 minutes to restore an image of the system partition on an emergency spare hard drive and a couple of hours to restore the data partition with half a terabyte of data. While I would say that such times are more than acceptable I was not quite happy about the time it takes to restore the data and have now found a simple solution to restore the data partition in just a few minutes as well.

Amazon Prime Video Now Usable On Linux, Too!
DRM protected content is a hotly debated topic and not without side effects but I have to admit I was somewhat glad when Netflix added support for Chrome and HTML5 playback on Linux back in 2014. At the time I also experimented with Amazon Prime video which was using Flash. Unfortunately this solution was quite unstable and thus unusable. Recently I noticed, however, that Amazon now also supports Chrome and HTML5 video playback on Linux. Over the past weeks I’ve watched a few full length movies and playback is now flawless. Well done, Amazon, thanks! … Just remove that DRM now please…
IPv6 When Roaming – Part 2
A couple of weeks ago I had a post in which I noted that while I have mobile IPv4v6 connectivity while I’m in my home country, I get IPv4-only connectivity when roaming by default. Now it looks like this is not universally true anymore.
How To Get an IPv6 Prefix From The LTE Network
Back in 2009 (!) I described the theory behind how a mobile network assigns an IPv6 Prefix to a mobile device. 3GPP TS 23.221 and TS 23.060 are a good starting point. 6 years later things have moved from theory to practice so I decided to write another blog entry on the topic, this time with some more details out of traces made in a live network.

How Many Simultaneous IP Addresses Does Your Mobile Have?
Once upon a time a PC was connected with a cable to a network and usually had one IP address. The same applied to smartphones until a couple of years ago. But no more, most smartphones today have more than one IP address at a time, at least some of the time. Any idea how many? Make your own count before reading on.

First Wifi Access Point With PMF Frames Sighted
In the past few years a number of hotel chains have experimented with Wifi De-associaten attacks to force venue guests off their own Wifi access points. Fortunately the FCC has responded quite sharply and so I haven’t seen further reports about such behavior in the wild. FCC rulings are good, countermeasures are even better. So far I haven’t seen them “in the wild” which was a bit disappointing. Up until now.
