Welcome to my personal hideout
hmm

My name is Tobias and I've always messed or had something going on with computers. I use the majority of my time with computers; mostly invested in programming and trying out new ideas. This site functions as a personal place and as a place where I show off my personal projects.

Tales of a patched sshd
17/10/2012 Filed in: Programming

Some months back I applied a this little patch and recompiled openssh. This patch records incoming login attempts on my ssh server in a convinient logfile; both the username and password. I thought this would be a great way to compile a nice little dictionary with username and passwords for bruteforce attacks. Just for fun of course. I didn't really think I would collect that many attempts. Today... months later I checked this very logfile. This is what I saw;

[root@hyrule ~]# wc -l /var/log/sshd_logged                                                                                                                                                   
138032 /var/log/sshd_logged

  138k of usernames and passwords. That is pretty impressive, if I may say so, considering my relatively low-in-traffic server.

The Venus transit
7/6/2012 Filed in: News

It has been a while since I last made a post. So here I come!

I watched the Venus transit on the 6th of June and what a great sight it was. I viewed the transition through my Celestron C8-SCT. The pictures aren't the best--mainly because of the atmospheric disturbances at the time and my own tiredness. The transit was from around 4 in the morning to 6.49. So I was up early, and I'm not that kind of type.

Here is one of the shots I got: 

 
You can also find this one and others in my gallery. Taken through my Celestron C8-SCT with a Canon 1000D camera attached.

My little ad-blocking tool; adblock-c
24/12/2011 Filed in: Programming

First of all, Merry Christmas to whomever is reading this article! ;)

 I hate ads, and only tend to enable them on pages I use frequently (to support the page). I've been using various ad-block extensions/plugins with the browsers I use--I only use Chromium for the time being. I like the extensions, but with Chrome the ad-block extension does not actually remove the ads--it only hides them--fair enough you may say, but I like not using bandwidth on ads or material I never actually see. Therefore you can go back to use your machines /etc/hosts file. This is actually much better, because you can then "blacklist" the domains that hosts the ads; affectively never using bandwidth from these domains/hosts. This is easy, you just add the hosts to your /etc/hosts file and set their pointing IP-address to your localhost... problem solved. This is tiresome to do manually because there are so many different hosts handling ads. Therefore I decided to write a little tool. I made the tool in C, rather than a shell-script, this is because I like C, simple as that.

The C program grabs ad-block hosts lists that are provided by third-party providers that frequently updates these lists--you can also add addional ad-block hosts sources to a file yourself and then fetch this file to the program. The C program then merge these hosts to your /etc/hosts file... and voila... ads are gone! You can add this program to your crontab and have it update your host-file on a regular basis; ie. every day or week. You are never dependent on a browser extension/plugin after this.

The source is freely available and I invite you to tamper with it as much as you'd want. You can of course just download, and compile it yourself, then use it on your machine.

Please fork it and make changes/additions/fixes, I'd appricate that! Or just give it a spin ;)

Over and out! Merry Christmas and a happy new year!
