How to encrypt a diskdrive in (X)Ubuntu Feisty with dm-crypt and LUKS

Today security is one of the key aspects in our daily life - sometimes conscious, sometimes unconscious. Security has many aspects and one of them is computer security or security of your or your business' computer data. In this tutorial I will show how to encrypt a whole disk drive using (X)Ubuntu Feisty, dm-crypt, and LUKS.

Feisty Fawn with Beryl and NVIDIA (not a how-to)

Finally, my AMD64 has working Beryl and Kubuntu. If there were party hat icons I'd sprinkle them all over this post.The solution arrived when my younger brother cleaned out his old office and found an NVIDIA MX440 that he had no use for. MX440 you say, obviously this story has a twist to it. I have had a partition with Feisty on it for several months now. I like the distribution. Everything seems faster. Unfortunately, it came with continued ATI Radeon 9600 configuration issues. My Radeon worked well in the Dapper. No Beryl, but it worked for google earth. And I had struggled to make it work. So I slapped that NVIDIA card in, tossed the ATI, and upgraded to edgy. Five hours later I was test driving a working install of beryl. (I also tried it in my test-install of feisty)A to B worked well. B to C was a nightmare. Just my luck that the day I pick to upgrade to feisty is the day the new NVIDIA 9755 driver arrived and dropped support for the MX440. Meanwhile, linux-restricted modules would provide it's own hidden barrier to installing the proprietary drivers from the company in the form of a module mismatch.

Installing and configuring a US Robotics Sportster Flash modem on Warty Warthog on a IBM Think Pad 390E

Hi Folks,  I'm a Linux Newbie,  but quite PC and Windows savvy.  It's a steep learning curve i can tell you!I'm trying to setup a cheap stable portable linux system for my sister,  and the combo of a download of Warty Warthog on an old IBM Thikpad 390E I've had lying about seems to do the trick.   Ultimately I'd like to be able to get the internal Winmodem to work,  but in the mean time I'd be really be happy in getting the US Robotics External Sportster Flash modem I've attached via Com1 working.  I can dial in but the connection either drops out or sometimes holds but remains unresponsive.  I suspect i need to use a different init string for the modem,  or adjust some sneaky setting that i'm unfamiliar with.  I'm with Comcen and i'm using their national dial in number and their dialup DNS settings.Any help would be much appreciated,  in trouble shooting the external modem,  or ultimately setting up the internal Winmodem

Using Sharp Fonts On A GNOME Desktop

You might have noticed that fonts are quite fuzzy on Linux desktops which can make your eyes ache if you have to sit in front of your computer all day long. Font rendering is still a little bit awkward and one of the last weaknesses of Linux desktops. This tutorial shows how you can make GNOME and all GNOME applications (such as Evolution, the file browser Nautilus, etc.) use sharp fonts. In fact, we will use the Microsoft Windows standard font, Tahoma, as the standard font in GNOME, too, which will make the desktop look quite familiar if you are used to working with a Windows desktop. http://www.howtoforge.com/sharp_fonts_gnome

How To Harden PHP5 With Suhosin (Debian Etch/Ubuntu)

This tutorial shows how to harden PHP5 with Suhosin on Debian Etch and Ubuntu servers. Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections. http://www.howtoforge.com/suhosin_php_debian_etch_ubuntu
