  • Remote support and process manipulation

    Sometimes I help friends that make their first steps in Linux world/shell scripting/etc. I’ve found that the best way to give remote technical support is over a “shared” terminal window. It can be done with screen commnad (short tutorial here) or kibitz which is part of the standard expect package. The basic operation is similar:…

  • Sending mail from command line

    Recently I wanted to add mail sending functionality to one of my scripts. This script runs on my desktop computer, so no fancy company mail servers/fixed IP/DNS records for me. When I googled it up I saw many different methods in varying complexity. My need was the simplest you can think of- just to send…

  • USB Multibooting

    I recently wanted to add multiboot support to my usb disk-on-key. I mainly use it for casual file transfers/play music on my car, but I also got BackTrack installed on it. From time to time I get to use it on a frined’s computer. BackTrack is one of many “live cd” operating systems, meaning you…

  • Cool command line stuff

    I made this list of cool things you can do from shell especially for desktop users. They all work on my ubuntu and most of them generic (except maybe apt-get which works for debian based distrubtions). The list is not ordered or categorized. It’s really just a bunch of things a little different from the…

  • Faking the Green Robot – Part 2

    It has been long time since Part 1, but I’ve been busy with other stuff. In the previous part, I started analyzing how “Green Robot” feature can be faked, or more precisely, how Android is identified by google talk servers. Last thing I found out was that Android’s talk application securely connects to gtalk servers.…

  • Ubuntu 10.04 Lucid Lynx

    Today, Canonical will release Ubuntu 10.04 LTS (long term support). I’m usually not so enthusiastic about new Ubuntu releases, but this time is different. They added some sweet features, well, at least for me, which didn’t get proper public relations. This is not a comprehensive review of the new features. It’s about new features I…

  • Paradoxes, self reproducing code, and bash

    I was always fascinated by paradoxes. They are just shamelessly out there, messing with our minds, sending us one message: we’re logically irresolvable, don’t f*ck with us. As a child I really liked this one: The statement below is true. The statement above is false. This is classical liar’s paradox. Each statement alone can be…

  • Man in the middle with TLS/SSL

    Man in the middle attack (aka MITM) is very famous and well known network attack. Lately I found myself playing with it, turning my theoretical knowledge into practical methods (on my own computers of course). I’m going to try explain the theory, as well as practical methods I tried, including attacks on TLS/SSL. Is it…

  • Faking the Green Robot – Part 1

    On last November, Google Labs released cool feature, called “Green robot icon”. If enabled, it turns the bubbles next to your chat buddies in Google Talk, into cute android robots, for buddies connected via android device. It might not be the best thing for android users’ privacy, but other than that I think it’s pretty cool, and I want…

  • This is how it all started

    Hey. I planned this post to be about Linux, FOSS and iPhone, starting with the sentence “I wasn’t always like this”, telling you guys about my transition from Windows to Linux desktop, the problems I had back then, and how Linux desktop is in a whole different place now, where you can plug Apple’s closed-encrypted-never-designed-to-work-on-linux…
