Open vSwitch over DPDK on Ubuntu
Jan 01, 0001
There are two approaches for using DPDK acceleration in DPDK. One is the openvswitch fork from intel, called dpdk-ovs the other is done directly in openvswitch with a different approach from intel. http://dpdk.org/ml/archives/dev/2014-March/001770.html - https://github.com/01org/dpdk-ovs VirtualBox preparations To run openvswitch with DPDK I used a virtual machine (VirtualBox) because the NIC I had on my laptop was not supported.

The only requirement is to have a virtual machine running the qemu-guest-agent.

Listen for 8080 first Bash Some versions of bash can send you a reverse shell (this was tested on Ubuntu 10.10):
PERL Here’s a shorter, feature-free version of the perl-reverse-shell:
There’s also an alternative PERL revere shell here.
Python This was tested under Linux / Python 2.7:
