Upside Downternet v2.0

Sunday, January 3rd, 2016

I’ve always wanted to implement upside-down-ternet, but lacked the resources. But now it’s 2016 and you can make your wifi-stealing-neighbour’s web browser do all the hard work. This means that a simple OpenWRT router will have enough power to flip the internet – all of it, except for the ssl-protected areas. (more…)

Lately I bought a Minix Neo X7 Mini. Next thing you know: I brick the box. Here’s how to unbrick the thing – with Linux. It’s rather easy, too! (more…)

Syslog-ng intrusion detection

Tuesday, August 27th, 2013

There seems to be a problem using the file() destination for /proc files in Linux. When implementing Securing Your Server With Syslog-NG you will run into it. Please read below.

(Not) rooting RK3066 systems

Friday, April 12th, 2013

The update updated, 2014-04-28: unbricking is fairly easy, see http://valentijn.sessink.nl/?p=517

Please note that I received some reports from people that tried to flash their RK3066 stuff – but it would not boot afterwards. And in fact, that’s what I experienced when I tried to flash my Minix Neo X5. (more…)

Securing your server with Syslog-ng

Sunday, February 20th, 2011

There are many programs that help you secure your servers. There are simple firewalling programs and there are complex network intrusion detection systems. Depending on your demands, there seems to be a solution for everyone. Unless you’re picky and you think you can do better – like I did, when I wrote my own combination of syslog-ng and Linux iptables, skipping the middle man.

August 2013 update. There seems to be a problem using the syslog-ng file() destination on /proc in Linux. See http://valentijn.sessink.nl/?p=458 for more information.

In part one we built a kernel module and put it somewhere in the filesystem. In part 2, we changed the inputattach utility to be able to use the new transmitter. Now we’re ready for the real part: install the Heli-X simulator.

Walkera helicopters under Linux – part 1

Wednesday, May 7th, 2008

A couple of months ago, I bought a Walkera Dragonfly #04, just for fun. While actually flying an RC helicopter is great fun, sometimes you will want to use a simulator. As Linux is my platform of choice, I tried using the Walkera transmitter with a serial cable to run a heli-sim. I found out how to do that; here’s the results of my quest. This article will be split in 3 parts: kernel; utility; Heli-X. This is the first part.

I will use Ubuntu Linux 8.04 Hardy Heron for my explanation. You can use other versions of Linux – but please beware, you will need a pretty recent kernel to be able to build the kernel module.
