Linux Everywhere

Linux Everywhere

This reminds me of a couple stories... I was on a trans-Atlantic flight when some of the screens stopped showing the films, so the flight attendant rebooted the section having the trouble. While it rebooted there were little penguins on all the screens... a grin inducing moment. Not to mention, the special effects of the Harry Potter franchise [...]

BackTrack 4 beta released

BackTrack 4 beta released

The Remote Exploit Development Team has just announced BackTrack 4 Beta. BackTrack is a Linux based LiveCD intended for security testing and we’ve been watching the project since the very early days. They say this new beta is both stable and usable. They’ve moved towards behaving like an actual distribution: it’s based on Debian core, they [...]

HOWTO: Write a Linux virus in five easy steps

HOWTO: Write a Linux virus in five easy steps

There is this rumor going around that Linux is virus free. It is said that the old-fashioned multi-user heritage of Linux (and other *nix OSs) prevents malware, since users are not normally running their programs in admin mode (as root user). We are reminded that execute bits are needed to run anything – contrary to Windows – and that execute [...]

HOWTO: Setup a reverse SSH tunnel

HOWTO: Setup a reverse SSH tunnel

Ok, so most of us know how to set up your standard SSH tunnel... when you create a secure link between a local port and a port on a remote box. Now recently I had to need to forward a port on a remote server to a local port on my laptop, which is behind a firewall. Turns out SSH can do this too. Check it out: ssh -nNT -R 9867:localhost:3000 [...]

Linux directory structure

Linux directory structure

In the Linux operating system, all file systems are contained within one directory hierarchy. The root directory is the top level directory, and all its sub-directories make up the directory hierarchy. This differs to other operating systems such as Windows which applies a separate hierarchy for each device and partition. /bin - binary [...]

Is it Windows 7 or KDE 4?

Is it Windows 7 or KDE 4? In this video, we take to Sydney's streets to find out what people think of what they think is a Windows 7 demonstration. The net result? Mainly, people just didn't like Vista. (more…)

Nomad & Compiz++ To Merge Back Into Compiz

Nomad & Compiz++ To Merge Back Into Compiz

In late 2008 we witnessed the release of Compiz++, a rewrite of the Compiz core in C++ plus other invasive work in order to improve this compositing window manager. With Compiz++ being a branch of Compiz and various other developers working on their own branches, the future of Compiz was unclear, however, today it has been cleared up [...]

Ubuntu Linux kernel vulnerabilities

Ubuntu Linux kernel vulnerabilities

A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 7.10 Ubuntu 8.04 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. Hugo Dias discovered that the ATM subsystem did not correctly manage socket counts. A local attacker could exploit this to cause a system [...]

Linux Kernel eCryptfs vulnerability

Linux Kernel eCryptfs vulnerability

Due to a vulnerability in the Linux kernel, a local attacker on a system with Linux kernel series 2.6 could crash the system to deny service to legitimate users or possibly obtain root privileges. Security Lab say the vulnerability is in fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before 2.6.28.1 allows local users to [...]

You Could Be the Next Face of Linux

You Could Be the Next Face of Linux

We've all seen them: on comes a commercial with a young, casually dressed,if somewhat unkempt, young man, and an older, portly man in a very middle-management-esque suit. The younger man announces "I'm a Mac" while the older responds "And I'm a PC," and the two go on to lament some critical design failure facing the PC to which the Mac is [...]

French Lawmakers Hope to Inspire Linux Revolution

French Lawmakers Hope to Inspire Linux Revolution

If the French National Assembly gets its way, the open-source Linux operating system will take over the governments of Europe, seizing on a weak economy to displace Windows. About 18 months ago, the Assembly shifted from running Windows on the 1,100 computers of its members and their assistants to running a version of Linux called Ubuntu. [...]

Ext4 to be the filesystem standard for Fedora 11

Ext4 to be the filesystem standard for Fedora 11

According to current plans, version 11 of Fedora, which is expected to arrive in late May, will use Ext4 as its standard file system. That's what the Fedora Engineering Steering Committee (FESCo) recently decided, following a heated discussion in an IRC meeting. If however Ext3's successor encounters big problems with the pre-release versions of [...]

The facts behind Microsoft’s anti-Linux campaign

The facts behind Microsoft’s anti-Linux campaign

Reminds me of Gandhi: "First they ignore you, then they laugh at you, then they fight you, then you win." From CNet News: Back in 2002, Jim Allchin was co-president of Microsoft's Platforms and Services Division and was, in his own words, "scared" of the momentum behind Linux, as noted in an email sent to several of his direct [...]

Linux succumbs to Windows users

Linux succumbs to Windows users

I've been using Linux since 1997, and while that doesn't quite elevate me to grizzled geekbeard status, it's long enough to have observed a whole lot of growth and changes. Most of them are good; but some of them are rather alarming. The changes that bother me the most are the ones that make it harder to understand and control your own system by [...]

Software or hardware RAID?

Software or hardware RAID?

The "Which should I use: software or hardware RAID?" question comes up often. I think I answer the question at least once every six months or so... and the responses to such a question are often filled with, in my opinion, inordinate praise of expensive hardware RAID solutions, and inordinate scorn for software RAID. This page is my attempt to [...]

HOWTO: Create a private encrypted folder in Linux

HOWTO: Create a private encrypted folder in Linux

eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux.It provides advanced key management and policy features. eCryptfs stores cryptographic metadata in the header of each file written, so that encrypted files can be copied between hosts; the file will be decryptable with the proper key, and there is no need to [...]

Linux 2.6.28’s five best features

Linux 2.6.28’s five best features

While you were likely to be opening up Christmas presents, Linus Torvalds was giving Linux users around the world a special present: the release of the next major Linux kernel: Linux 2.6.28. We had some time to tinker with this latest and greatest Linux, and it's my kind of Christmas present: solid improvements to my favorite operating system. [...]

HOWTO: Install Ruby on Rails on Debian

HOWTO: Install Ruby on Rails on Debian

Installing Rails on Debian or Ubuntu is quite simple. To ensure that you have a Rails-compatible version of Ruby installed, do not install the old (and possibly broken) version of Ruby with apt-get/aptitude. Rather, install Rubygems and have it fetch Ruby for you. Again... Do not install rails using apt-get/aptitude! The debian repository includes [...]

HOWTO: Setup Network Bonding

HOWTO: Setup Network Bonding

What is bonding? Bonding is the same as port trunking. In the following I will use the word bonding because practically we will bond interfaces as one. But still... what is bonding? Bonding allows you to aggregate multiple ports into a single group, effectively combining the bandwidth into a single connection. Bonding also allows you to [...]

The future of Compiz

The future of Compiz

...from the Freedesktop.org Compiz maillist. Where are we going? It's time to start thinking ahead and really figure out how to make Compiz survive, specially in lieu of Dennis' suggestion. The reality is that there has been the equivalent of no progress since the merge. We've basically only been in maintenance mode. The reason for [...]
