Blogging on tech, hosting and security
I recently got very annoyed by a startup error, which looked like in the picture below and said the following:
There was a problem starting C:\Users\username\AppData\Conduit\BackgroundContainer.dll
The specified module could not be found.

I got a bit hyped lately about reading. I basically started reading a lot about subjects that interest me ( IT Security, personal development etc) – for more on that check my Learn section where i post details about what i read and listen to. Since carrying a lot of books with me is not my thing i decided that i should be an ebook-reader. I got into a lot of discussions about why buy an ebook reader and not a tablet, but that’s related to my requirements. Continue reading “Sony Reader PRS-T3”
I first started blogging on a WordPress.Com hosted blog. After i bought my domain i knew that i had to move everything in an automated fashion, or else i’d kill myself. Luckily WordPress has the Export/Import features that saves a lot of time. It also imports media attachements (pictures) but not as i expected. For some strange reason, it copied some of the pictures but most of them were just linked to the old address. Continue reading “Migrating media attachements from a WordPress.Com blog”
On the 6th March in Odense there will be a job fair, full of big companies, unions and and representants from municipalities around Denmark. This looks like a nice interniship opportunity. For a proper description, let’s just read what they’re saying: Continue reading “Karrieredagene Denmark 2014”
One of the supervisors asked for a monthly report of everybody that has borrowed devices and haven’t returned them yet. You can do that manualy by going to the Reports tab and clicking on Bibliography Checkout Listing.
My plan was to figure out how to:

I did some nmaping on my Windows PC today, and i’ve discovered an unusual open port:
17500/tcp open db-lsp
Aparently port 17500 tcp is Dropbox LanSync Protocol (db-lsp); used to synchronize file catalogs between Dropbox clients on your local network. This service makes a lot of “noise” , sending broadcast messages very often. It is also a common false-positive for Snort. Continue reading “Port 17500 TCP open on Windows PC”
PCAP stands for Packet CAPture. A PCAP file holds network traffic/packet information, captured in a certain period.
Uses
Network forensics – an average or big company network can generate GBs of traffic daily. This traffic (or at least a part of it) is stored for later analysis. If the security departament has detected a breach/intrusion in the network, PCAP files are essential to look at, in order to better understand the situation and why did it happen
Testing your IDS/NSM – let’s say you just deployed an IDS in your network. What better way to test if not by confronting with the traffic that you want to protect from?
Exercise – PCAP files can be a great learning material for networking/IT security students. By displaying your data properly, all key elements of a packet can be identified and learned about much more interactively and easily than plain courses. Continue reading “What to do with PCAP files?”
Debian and derivated linux distros (Ubuntu, Linux mint) use APT to manage software and software locations. It is so easy that you can install everything with a simple command like :
apt-get install “something”
Where “something” can be a an app that you know about or it can be something that you don’t remember, and just use TAB to see what suggestions there are. When you can’t install a certain app (that you know for sure it can be installed) you typically see this error:
E: Unable to locate package “something” Continue reading “How to add a new Debian repository”
