The following packages are needed to run shocker.
Because most distributions do not ship a new enough version of util-linux you will probably need to grab the sources from here and compile it yourself.
Additionally your system will need to be configured with the following:
bridge0and an IP of 10.0.0.1/24
bridge0to a physical interface.
Even if you meet the above prerequisites you probably still want to run shocker in a virtual machine. Shocker runs as root and among other things needs to make changes to your network interfaces, routing table, and firewall rules.
btrfs is not available on your machine. Luckily many package
managers offer a way to install this in a single command:
sudo apt-get install btrfs-tools
That means we don't have a
btrfs filesystem mounted, so let's create one!
From a file! Because that's easier than doing partitions!
# create a new filesystem from an empty file# skip this step if mounting an actual device$ dd
Not every distro adheres to the Linux Filesystem Hierarchy Standard, but no need to sweat about it, we can create our own:
$ sudo mkdir /tmp$ sudo chmod 1777 /tmp # open to everyone + set sticky bit
This means that a network device is not found. To enable it run
shocker route <devicename> to setup
iptables rules and link the device.
This means cgroups are not yet mounted on your system. Use
cgconfig to start
them up (example below uses System V init):
$ sudo service cgconfig start
