Last week I had to migrate my dns server and to do stuff properly I also added a couple of slave DNS servers just to make sure. Problem: ~15 domain names that need to be added to a fresh bind installation. The zone files didn’t change too much so that was fine, sed helped me [...]

Yakuake
I’m going to start a series of blog posts about linux apps that I can’t live without. After a fresh system install these are the first installed. The more and more I use Linux the more I find myself stuck into some console. While the default terminal app shipped with Gnome is just fine for [...]
Hardware Keylogger Detection
Intro Keyloggers are nifty things used to grab keyboard input for later analysis and use. The most common type of keylogger is the software keylogger as it is just some program that records key presses. Running it usually requires administrator privileges and this limits the attack surface as one must first gain this type of [...]
Parsing XML data using bash and standard Unix tools
Parsing XML can be a tedious and unpleasant job if you insist on using just standard Unix tools like sed, awk, cut, grep and so on. One might say that it’s better to use python/perl/ruby/other language that ships with a full blown XML parser and use the standard Unix utilites for what they were meant [...]
Internet Exchange Points
The largest Romanian IXP is Interlan . Funny enough, Interlan is a response of the smaller ISPs to the other big Romanian IXP, Ronix. Because 3 years ago joining Ronix was a complicated affair, a few small companies decided to take matters into their own hands. Currently, Interlan has 3 times more traffic than Ronix.

Joining pdfs in a Debian based Linux distribution can be easily done by using the pdfjoin utility. It is provided by the pdfjam package. One only [...]
Choosing random entries from a group
In the past two weeks we had a lottery-type thing on RGC.ro (Romanian Guitarist Community). Proguitar, the official importer of Fender products in Romania, wanted to give-away a custom made Fender Stratocaster electric guitar. To register, the community users had to fill out a form and choose from a series of custom options for the [...]
SNE Update 1
So over two months have passed since my last update. I was either busy or not in the mood to update my blog. I will try to make up for lost posts somehow… I’m now enrolled to the System and Network Engineering Master at University of Amsterdam. How I got here?
Great success!
(that’s what Borat would say) Today I’ve received wonderful news! I have been accepted to the System And Network Engineering Master at the University of Amsterdam! Starting from the end of August I’ll be relocating to Amsterdam for one year of full geek experience (hopefully!). I can not thank enough my girlfriend on being such [...]
Get your personal email account
Most people use free email services like yahoo, gmail or live. Unfortunately all the nice sounding email addresses are taken by now so new users have to come up with strange combinations like johndoe19__smth_smth@yahoo.com. That’s very hard to remember and it sounds very unprofessional. Having an online presence is no longer such a big deal. [...]
