Timevault is an automatic backup utility that takes a snapshot of your current filesystem or directory for pre-defined amount of time, which can be used later to retrieve damaged files or folders. Timevault is in beta stage of development and can be downloaded from https://launchpad.net/timevault.

You already know how to get data from your Firefox Cache and why you should not save your passwords using Firefox, in this post i will bring to you an interesting hack which allows you to open Firefox Bookmarks using a keyword.

You can open any firefox bookmark using a simple keyword attached with it. The keyword needs to be stored as a property for the bookmark. This hack is pretty useful when trying to open long URL’s.

For example, lets assume you wish to save www.technofriends.in into your bookmarks folder as one of the favorite item and would like www.technofriends.in to open up anytime you enter TF and press enter in your firefox browser tab/window.

Often we get stuck with the Windows Safely Remove Hardware Icon, trying to stop the device which just doesn’t stop. In such scenarios, the question most of us ask is ” Now, how do i remove this device safely, without losing any data? “

This post, describes two methods of removing USB Devices safely from your Computer, even if the Windows Safely Remove Hardware program gives off with a message ” The device cannot be stopped right now”

Kill the Process

This is the first way to go, try opening your Task Manager ( Pressing CTRL+ALT+DEL or Right Clicking on the Task Bar and selecting Task Manager from the menu)

Question: I want to reset counters in /proc/net/dev (also shown in ifconfig output as RX and TX bytes) and thus I have to unload network interface driver. How to do it?

Answer: There are two commands in Linux CLI coming by default which would help to unload drivers: rmmod and modprobe. First of all it is necessary to find what kernel module controls certain NIC and then unload that module. For example, you have VIA VT6102 (RHINE-II) network card that is recognized by Linux as eth0 and want to disable its driver temporarily. Just execute the following:

"sudo rmmod via-rhine" or "sudo modprobe -r eth0" (or "sudo modprobe -r via-rhine"). You can use command dmesg to determine the name of kernel module you wish to unload.

In my last post, i wrote about Windows XP SP3, in this post, i shall be explaining the process to identify the version of Windows and Windows Service Pack installed on your computer.

In the good old days of DOS, we used to enter ver at the command prompt to get the version number of the Operating System being run on the PC. You can use the same command in Windows as well to identify the Operating System version.

Question: How can I restrict/allow access to certain service on timely basis with iptables? For example restrict access to SSH between 7:00 pm - 8:00 am on weekdays?

Answer: You are welcome to use iptables patch-o-matic extension (pom or p-o-m) that allows you to match a packet based on its arrival or departure (for locally generated packets) timestamp. The syntax is the following:

iptables RULE -m time --timestart TIME --timestop TIME --days DAYS -j ACTION

1) There are quite a few applications in linux that has the ability to download torrent from the terminal. rtorrent is perhaps the most easiest to use and widely configurable out of all of them. To kick off with downloading any torrent file, you simply have to provide the link location of the torrent file, ie. rtorrent <torrent_address>

rtorrent is highly customizable and and can be configured by editing the configuration file located in ~.rtorrent.rc by default. You can assign rtorrent to load your own custom configuration file using this command: rtorrent -n -o import=~/custom.rc

Some interesting entries you could use in your configuration file; by default rtorrent does not come with a config file.

Question: How can I get information about hardware manufacturer, model name, serial number, BIOS information using Linux command line (CLI)?

Answer: You are welcome to use dmidecode which helps to get information about your system’s hardware as described in your system BIOS. That information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details depending on the manufacturer.

You already know that Phishers employ various methods to phish your critical data and there are certain ways to protect your data, and one of the ways to protect yourself is by employing the secure connection techniques like HTTPs and checking for that small lock icon in your browser.

Static routing is the term used to refer to the manual method used to set up routing. An administrator enters routes into the router using configuration commands. This method has the advantage of being predictable, and simple to set up. It is easy to manage in small networks but does not scale well.

Question: How can I save static routes I set up in my Fedora/RedHat/CentOS Linux after I reboot server?

Answer: In Fedora Linux (or RedHat, CentOS) you can set up static routes for certain network interface (for example eth1) by editing file /etc/sysconfig/network-scripts/route-eth1.

For example, you have to save static route added by the following command:

My love for xkcd comics has influenced me to write this modified autoconfig “cracking” tool that cracks wifi WEP password from your neighbors, exactly the way shown in xkcd comic number 416:

Here is the tool in action:

As you can see there are some state of the art features added to this version. This tools is the result of weeks of sleepless night, yet I am not too sure whether I should release this version to the public. There are some sick people out there who can seriously abuse this tool. If you are still skeptical about the existence of this, you can watch it live in action:

Remember, hacking is serious business.
