Command Line Methods to Completly Delete a Hard Drive in Linux

Here are 2 methods to completly dlete the content of an hard drive with dd and shred commands. With those methods you won’t be able to recover the data. This can be useful in case you want to sell, throw away your hard drive / computer or have doubtful activities. If the partitions you want to delete are system (boot) partitions you’ll need to start your system with a live CD / USB such as SystemRescueCD or GParted. Finding the location of a drive or partition In order to know the exact path for your drive, you can use the fdisk command as root or sudoer: # fdisk -l Disk /dev/sda: 1887.4 GB, 1887436800000 bytes 255 heads, 63 sectors/track, 229467 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 25 200781 83 Linux /dev/sda2 26 229335 1841932575 83 Linux […]

Cross-compiling FreeRDP Windows Remote Desktop Client for ARM Linux (in Debian/Ubuntu)

Last month, I wrote the instructions to Cross-compile VMWare View for ARM Linux as I intended to “run” Windows 8 in an ARM client (most likely the Raspberry Pi) via PCoIP. However, the procedure to do so seems slightly complicated and requires to purchase a specific VMWare server software (VMware vSphere 5) or download a free trial. The good news is that there are other options such as VNC or RDP (Remote Desktop protocol) and Remmina, a Remote Connection client is available for Linux. As nothing is ever simple, another issue occured: if you are using a stable release of Linux (e.g. Debian Squeeze, Ubuntu 11.10) they come with older version of Remmina and either the connection is successful but the display is garbled (Version 0.7.x) either it crashes when connecting to Windows 8 via RDP (Version 0.8.x). The latest version (Remmina 1.0.0) fixes the problem and is available in […]

How to build qemu-system-arm in Linux

Most (all?) Linux distributions have a binary package for qemu-system (including qemu-system-arm) in order to emulate non-x86 targets such as ARM, MIPS, PPC, Alpha and more. However, in some case you may need to very latest version of qemu-system and it may not be able yet for your distribution. Here’s how to do to build qemu-system-arm without building all qemu-system-***: Download the latest stable version of qemu (qemu 1.0.1 at the time this post was written):

wget http://wiki.qemu.org/download/qemu-1.0.1.tar.gz

1	wget http://wiki.qemu.org/download/qemu-1.0.1.tar.gz

or get the latest source code (development tree) which has the very latest features and bug fixes, but may not work or compile:

git clone git://git.qemu.org/qemu.git

1	git clone git://git.qemu.org/qemu.git

or get the latest source code from linaro (which may be more up-to-date for ARM targets):

git clone git://git.linaro.org/qemu/qemu-linaro.git

1	git clone git://git.linaro.org/qemu/qemu-linaro.git

Configure qemu to build ARM targets:

cd qemu
./configure --target-list=arm-softmmu,arm-linux-user

1 2	cd qemu ./configure --target-list=arm-softmmu,arm-linux-user

Build and install qemu-system-arm:

make -j 2
sudo make install

1 2	make -j 2 sudo make install

Verify the latest version of qemu-ssytem-arm is installed:

# qemu-system-arm --version
QEMU emulator version 1.0,1, Copyright (c) 2003-2008 Fabrice Bellard

1 2	# qemu-system-arm --version QEMU emulator version 1.0,1, Copyright (c) 2003-2008 Fabrice Bellard

Instructions to Run Raspberry Pi Fedora 14 Remix in QEMU

As mentioned in my previous post, the Raspberry Pi Foundation has just released the Fedora 14 Remix SD card image that can be installed either via installer (easiest method) or using dd / windd as with the previous image. In this blog post, I’ll give the instructions how to run Raspberry Pi Fedora 14 Remix in QEMU using a similar method than the one I used for Debian Squeeze. I tested since in machines with Ubuntu 10.04 LTS and Debian 6.0.4. Download the image using BitTorrent raspberrypi-fedora-remix-14-r1.img.gz.torrent or via the HTTP link available on Raspberry Pi Download page. Decompress the image:

gzip -d raspberrypi-fedora-remix-14-r1.img.gz

1	gzip -d raspberrypi-fedora-remix-14-r1.img.gz

Download kernel 3.0.4 image for qemu, if you don’t have it yet.

wget http://dl.dropbox.com/u/45842273/zImage

1	wget http://dl.dropbox.com/u/45842273/zImage

Since the rootfs is full (in the real board it will be resized to the size of the SD Card), we need to increase the size of the rootfs partition. First create and empty 3G […]
