In a surprising development that seems really strange and unnecessary, Firefox 2.0 won’t go to the previous page when I press the “backspace” button on the keyboard. I have grown used to this over the period I have used Firefox. The fact that I can’t use backspace the way I am used to has been annoying me no end. So I decided to dig a little deeper.

The feature was removed to fix a bug. But then, until the bug fix propagates to a firefox build available on Ubuntu, one has to resort to a little scratching to fix the matter. Here’s how you resurrect the backspace button in Firefox 2.0.

Automatix is a graphical interface for automating the installation of the most commonly requested applications in Debian based Linux operating systems.

Installing Popular Applications On Your Ubuntu Desktop With Automatix2


This tutorial was written while offline and without any kind of browser open. That’s right. You can blog right from your gnome-based desktop with the greatest of ease!

Tutorial for the day: Installing and blogging with Drivel.

To install Drivel you can use the basic methods we’re familiar with. Via the command line or from “Applications” > “Add / Remove” > search:Drivel. (command line “sudo aptitude install drivel”

You can then access Drivel from your Applications menu inside the Internet section.

Some times you want to use iSO images without burning them.If you don’t want to waste your CD’s/DVD’s here is the simple possible solutions using these tips you can mount and unmount ISO images without burning them.

I know two possible solutions

1) Using Nautilus Scripts
2) Using kernel loop module

Now we will see each one in detailed

Mount and Unmout ISO images without burning them


There are times when people make mistakes, and manage to do crazy things to working systems. It wasn't so long ago that a hasty deletion caused me all kinds of problems. Recently I read of an unfortunate sysadmin who managed to recursively change permissions on their root filesystem - and here is my attempted solution.

The problematic command was:

(none):~# chmod -R 777 /

escuing a system with massively broken filesystem permissions


Still in this case, I had to install several times an older version of ImageMagick. Why? Not for the application itself, but because of some applications that relied on the php wrapper (the imagick pecl module). This compiles fine with ImageMagick 6, but many functions fail. So in order to have the php module working properly I had to first install imagemagick 5 that is the last version the php module works fine.

I will show how to install ImageMagick 5.5.7 (the latest version available from the 5 branch) from sources on a Debian Etch system. Debian obviously contains packages for ImageMagick (v. 6.2.4 at the time of writing this post), that can be installed as easy as

Install ImageMagick 5.5.7 on Debian


You've spent hours installing, configuring, and tweaking your system into perfection. Every device is working properly, every patch applied, every last last application is up to date, and your system is contently purring like a lion with a belly full of wildebeest. This is a prime time to save an image of your system in case anything screws it up. There are many commercial solutions available, but what free utilities will properly back up your system?

Backing up your system with free software

Proxmox VE 4.3 released

Proxmox Server Solutions GmbH today announced the general availability of Proxmox Virtual Environment 4.3. The hyper-converged open source server virtualization solution enables users to create and manage LXC containers and KVM virtual machines on the same host, and makes it easy to set up highly available clusters as well as to manage network and storage via an integrated web-based management interface. The new version of Proxmox VE 4.3 comes with a completely new comprehensive reference documentation. The new docu framework allows a global as well as contextual help function. Proxmox users can access and download the technical documentation via the central help-button (available in various formats like html, pdf and epub). A main asset of the new documentation is that it is always version specific to the current user’s software version. Opposed to the global help, the contextual help-button shows the user the documentation part he currently needs. Read more

  • New Open Source Linux Ransomware Divides Infosec Community
    Following our investigation into this matter, and seeing the vitriol-filled reaction from some people in the infosec community, Zaitsev has told Softpedia that he decided to remove the project from GitHub, shortly after this article's publication. The original, unedited article is below.
  • Fax machines' custom Linux allows dial-up hack
    Party like it's 1999, phreakers: a bug in Epson multifunction printer firmware creates a vector to networks that don't have their own Internet connection. The exploit requirements are that an attacker can trick the victim into installing malicious firmware, and that the victim is using the device's fax line. The firmware is custom Linux, giving the printers a familiar networking environment for bad actors looking to exploit the fax line as an attack vector. Once they're in that ancient environment, it's possible to then move onto the network to which the the printer's connected. Yves-Noel Weweler, Ralf Spenneberg and Hendrik Schwartke of Open Source Training in Germany discovered the bug, which occurs because Epson WorkForce multifunction printers don't demand signed firmware images.
  • Google just saved the journalist who was hit by a 'record' cyberattack
    Google just stepped in with its massive server infrastructure to run interference for journalist Brian Krebs. Last week, Krebs' site, Krebs On Security, was hit by a massive distributed denial-of-service (DDoS) attack that took it offline, the likes of which was a "record" that was nearly double the traffic his host Akamai had previously seen in cyberattacks. Now just days later, Krebs is back online behind the protection of Google, which offers a little-known program called Project Shield to help protect independent journalists and activists' websites from censorship. And in the case of Krebs, the DDoS attack was certainly that: The attempt to take his site down was in response to his recent reporting on a website called vDOS, a service allegedly created by two Israeli men that would carry out cyberattacks on behalf of paying customers.
  • Krebs DDoS aftermath: industry in shock at size, depth and complexity of attack
    “This attack didn’t stop, it came in wave after wave, hundreds of millions of packets per second,” says Josh Shaul, Akamai’s vice president of product management, when Techworld spoke to him. “This was different from anything we’ve ever seen before in our history of DDoS attacks. They hit our systems pretty hard.” Clearly still a bit stunned, Shaul describes the Krebs DDoS as unprecedented. Unlike previous large DDoS attacks such as the infamous one carried out on cyber-campaign group Spamhaus in 2013, this one did not use fancy amplification or reflection to muster its traffic. It was straight packet assault from the old school.
  • iOS 10 makes it easier to crack iPhone back-ups, says security firm
    INSECURITY FIRM Elcomsoft has measured the security of iOS 10 and found that the software is easier to hack than ever before. Elcomsoft is not doing Apple any favours here. The fruity firm has just launched the iPhone 7, which has as many problems as it has good things. Of course, there are no circumstances when vulnerable software is a good thing, but when you have just launched that version of the software, it is really bad timing. Don't hate the player, though, as this is what Elcomsoft, and what Apple, are supposed to be doing right. "We discovered a major security flaw in the iOS 10 back-up protection mechanism. This security flaw allowed us to develop a new attack that is able to bypass certain security checks when enumerating passwords protecting local (iTunes) back-ups made by iOS 10 devices," said Elcomsoft's Oleg Afonin in a blog post.
  • After Tesla: why cybersecurity is central to the car industry's future
    The news that a Tesla car was hacked from 12 miles away tells us that the explosive growth in automotive connectivity may be rapidly outpacing automotive security. This story is illustrative of two persistent problems afflicting many connected industries: the continuing proliferation of vulnerabilities in new software, and the misguided view that cybersecurity is separate from concept, design, engineering and production. This leads to a ‘fire brigade approach’ to cybersecurity where security is not baked in at the design stage for either hardware or software but added in after vulnerabilities are discovered by cybersecurity specialists once the product is already on the market.

Ofcom blesses Linux-powered, open source DIY radio ‘revolution’

Small scale DAB radio was (quite literally) conceived in an Ofcom engineer’s garden shed in Brighton, on a Raspberry Pi, running a full open source stack, in his spare time. Four years later, Ofcom has given the thumbs up to small scale DAB after concluding that trials in 10 UK cities were judged to be a hit. We gave you an exclusive glimpse into the trials last year, where you could compare the specialised proprietary encoders with the Raspberry Pi-powered encoders. “We believe that there is a significant level of demand from smaller radio stations for small scale DAB, and that a wider roll-out of additional small scale services into more geographic areas would be both technically possible and commercially sustainable,” notes Ofcom.
