cheaper Router as a general problem Some years ago,I had a very cheap router. A TP-Link DIR 600. The router made my very unhappy. For several reasons. First, the software that was operating on the Router were very limited. How limited? I was able only to set a few firewall rules (DNAT for example) on my own. When I recall correctly, i wasn’t able to redirect any port.
Second, the little insight to the devices I had.
This morning I got a info about a security breach at Atlassian. To be precise, HipChat. The “HipChat security notice”. The news page I was reading additionally pointed out a security vulnerability in Atlassians confluence. I got a chill in this moment. Somehow I got this wrong. I understood there would be a new vulnerability.
Because of a bad Internet connection I wasn’t able to the entry article(just got the header).
Hugo allows you to get very easy a new theme. Sometimes this new theme have some option you don’t want. For example:In this theme there is by default two additional menus. One for tags, for for categories. That’s something nice.
However, both menu had a very long list, that than needed scrolling bar. The scrolling bar broken than the design of the theme.
My fix for this was disable the two menu for categories and tags.

I attended the 33c3 in Hamburg. A awesome event, as always. One of the slogan: “use more bandwidth!”. To display the current amount of data that has been sent a dashboard (Note: Down to this time of the year) was created. I want to have something similar. So I started digging into the dash board while be on the congress. Which is running on grafana.
Grafana What is grafana?
I wish everyone a happy new year!

I like to highlight this:
… namely that powerful corporations were constantly looking for, and in many cases already applying, a wide variety of techniques for controlling people without their knowledge.
It gives you hint what to expect.

Programming A Hearthbleed in Rust…
Just because you’re using a type save language don’t mean you can’t leak plaintext. This applies to Rust (Tedbleed) as Java (JetLeak).However the type safeness would reduce the impact of the vulnerability.
How Hearthbleed would be in Rust.
Tony Arcier takes the time to disect the issue and comes to the conclution that rust would have prevented heartbleed.
Merry Christmas to everyone!

On a quick note
I had to limit the amount of packages that was directed to a single port. Usually this can be configure within the boundaries of the application. However this was an UDP based application and I wasn’t aware of any configuration parameters what would have allow this.
So I jumped to the firewall and limit the rate via iptables:
iptables -A FORWARD -s 0.0.0.0/0 -d 10.0.0.3/32 \ -p udp \ -i eth0 \ -o virbr0 \ --dport 9987\ -m state --state NEW \ -m limit --limit 5/second \ -j ACCEPT iptables -A FORWARD -s 0.
For a class in my university, I have to flash a ATmega8 Chip. This is on a custom PCB including a own quartz, to allows the usage of a USB Port as interface instead of a classic ICSP. The chip will be registered to your PC as USB devices. On a Windows System you can use the Atmel Studio, to program it. It will create special a .hex file, including the compiled code of yours.
