Just to note, Jamin accepted the pull-request so pkt2flow can be downloaded – with OSX and homebrew support – at it’s regular address: https://github.com/caesar0301/pkt2flow
Ending my hiatus, I present you pkt2flow; it takes a PCAP-file and splits it up into it’s individual TCP- and UDP-streams. It’s not my original work, but I adapted it to compile on OSX. Also, Isotopp contributed a patch for the SConstruct file to make it work with homebrew. I’m currently planning a portfile for MacPorts and are also thinking of extending the functionality so that it also works with .1q tagged frames in the PCAP.
Grab it at https://github.com/yalla/pkt2flow until the original author accepted my pull-request if you’re interested in building it for OSX.
Also I spend my time mostly on Google+ nowadays, but I plan to revive this whole thing here with more in-deep articles not suitable for Google+.
Do you like free software? If yes, I’d like to ask you to show your support – anonymously – on the website of the Free Software Foundation Europe: http://fsfe.org/support/?yalla
What is this request about? The FSFE likes to know how many people care about free software and the issues we’re having. Also, we want to show off how many people are caring about free software issues, so that we can raise awareness in the public and in politics.
A lot of people – like you – care about free software – if it’s Linux, OpenOffice, GIMP or just Mozilla Firefox – without speaking up. This survey won’t disclose your identity to the public, but only to the FSFE. It would be really really cool if you could sign up as a supporter.
Here is the explanation. As some of you know, I’m a Fellow of the Free Software Foundation Europe (“FSFE”). As a fellow, I take care of all aspects about free software. I’d be happy to let you know, in case you didn’t know yet, that I will answer you any question about free software if you have any.
So, if you’re interested, sign up! And drop me a line or start a discussion below in this posting, if you have questions, remarks or suggestions.
If you wondered where I’ve been the last year, I’ve been on Google+ and somehow didn’t feel like posting anything useful in the last couple of months.
However, I’ve got quite a few cool projects running:
- Got me a pair of Infiniband Adapters. Plan: Brew up a software which will receive data via IP on multiple IB-nodes and write the data to distributed shared memory via RDMA/IB. Then let one or more IB-nodes read from that (ring)-buffer and aggregate data so that it can be shoved into an RDBMS.
- Brew up an AWS image for easy BOINC-crunching while preserving the workunits on a headnode. Why? Because images on the AWS spot-market are cheap. But spot-machine do not retain any data. So I might be putting it into S3 along with some headnode directing which machine (machines id keeps changing!) can work on which workunits.
- Become more confident in the language Erlang. Got quite a few projects which could benefit from easy protocol prototyping with ASN.1 in Erlang. Stay tuned.
- Got me a Spartan-3E FPGA board. Not sure what to do with it, but it’s awesome :)
- Was playing around with GNU Radio and my RTL DVB-receiver recently.
- Doing some serious Openstreetmap work recently.
- Mrs. Janssen and be got fond of geocaching. Lot’s of outdoor stuff. Sweet!
- Been to this year’s Linuxbierwanderung. Was awesome!

Now SEGA took the lead, continuing the tradition of music games with special controllers.
Live, from Digital Signage Show, we present you:
Only this time, the controller is your wiener.
Yesterday was World IPv6 Day. From the German perspective, there was a huge spike in traffic-increase on that day. Not so much as one might have expected, but still a significant increase:
Interestingly, although IPv6 day is over, the traffic didn’t decrease. For the fun, I checked with youtube.com – and it’s still serving traffic in IPv6!
Now compare to the the montly stats:
Nethertheless, IPv6 traffic is still very little compared to regular IPv4 traffic:
So while IPv6 peaked with 1.8 Gbit/s, IPv4 at DE-CIX is still a 3.2 TBit/s. Which is about 2000 times more traffic.
But what does that tell us?
Thinking of the IPv6 traffic stats I derive the following things. First, I assume that IPv6 day didn’t make user migrate to IPv6. I think – although I can’t prove it – that existing IPv6 users kept using the Internet like they used to.
But the statistics tells us one thing: That a lot of people were prepared and ready – the early adopters. Since youtube.com is still online with v6 – and the traffic didn’t change to much – I think that either youtube.com made up most of the v6 traffic, or, that most of the websites are still live with v6.
Whoever you are, running IPv6 since yesterday: Keep going! And let’s hope those traffic stats keep increasing over time.
If you’re interested in IPv6, and didn’t bother to try it, go and get yerself some v6 at the following spots:
