Kali Linux Debian Repositories

Posted by root on Tuesday Oct 22, 2013 Under Uncategorized

What is kali linux ?? please refer : http://kali.org

Since kali linux is build based on debian we can directly install packages using package manager in any debian operating system just by adding following repositories.

Add the following repositories in /etc/apt/sources.list

deb http://http.kali.org/kali kali main contrib non-free
deb-src http://http.kali.org/kali kali main contrib non-free
deb http://security.kali.org/kali-security kali/updates main contrib non-free
deb-src http://security.kali.org/kali-security kali/updates main contrib non-free

now for example you want to install sqlmap

#apt-cache search sqlmap

#apt-get install sqlmap

Install KVM QEMU Virtual Machines in Debian

Posted by root on Sunday Oct 20, 2013 Under Bash, Linux, SSH, Ubuntu, VM


KVM is a full virtualization solution for Linux on x86 (64-bit included) hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.

In Debian, Xen and VirtualBox are alternatives to KVM.



Install the qemu-kvm package with apt-get or aptitude, e.g. using this command:


aptitude install qemu-kvm libvirt-bin

The daemon libvirt-bin daemon will start automatically at boot time and load the appropriate kvm modules, kvm-amd or kvm-intel, which are shipped with the Linux kernel Debian package. If you intend create VMs from the command-line, install virtinst.

In order to be able to manage virtual machines as regular user you should put this user into the libvirt group:


adduser youruser libvirt


Setting up bridge networking

It can be useful to set up a bridge for the KVM VMs as described here at QEMU page.


Managing VMs from the command-line

You can then use the virsh(1) command to start and stop virtual machines. VMs can be generated using virtinst. For more details see the libvirt page. Virtual machines can also be controlled using the kvm command in a similar fashion to QEMU.


Managing VMs with a GUI

On the other hand, if you want to use a graphical UI to manage the VMs, you can use the Virtual Machine Manager virt-manager.

apt-get install virt-manager


Migrating guests to a Debian host


Migrating guests from RHEL/CentOS 5.x

There are a few minor things in guest XML configuration files (/etc/libvirt/qemu/*.xml you need to modify:

  • Machine variable in <os> section should say pc, not rhel5.4.0 or similar
  • Emulator entry should point to /usr/bin/kvm, not /usr/libexec/qemu-kvm

In other words, the relevant sections should look something like this:


    &lt;type arch='x86_64' machine='pc'&gt;hvm&lt;/type&gt;

  --- snip ---


If you had configured a bridge network on the CentOS host, please refer to this wiki article on how to make it work on Debian.



No network bridge available

virt-manager uses a virtual network for its guests, by default this is routed to and you should see this by typing ip route as root.

If this route is not present in the kernel routing table then the guests will fail to connect and you will not be able to complete a guest creation.

Fixing this is simple, open up virt-manager and go to “Edit” -> “Host details” -> “Virtual networks” tab. From there you may create a virtual network of your own or attempt to fix the default one. Usually the problem exists where the default network is not started.

cannot create bridge ‘virbr0’: File exists:

To solve this probelm you may remove the virbr0 by running:

brctl delbr virbr0

Open virt-manager and go to “Edit” -> “Host details” -> “Virtual networks” start the default network.

You can check the netstatus

virsh net-list --all


Optionally, you can use bridge network BridgeNetworkConnections
