Configurable user-space network stack, aimed to simulate network error condition, delays and vulnerabilities.

Integratio can be configured via JSON Configuration test cases, which describes which application level content should be delivered and in which points delayed should be introduced.

Introduction of delays happens by state in the TCP state machine. State transition will wait for the test case defined value before execuring the state transition.

Test cases can be described in JSON by category ('time', 'content') and combined together. For example, the short demo below shows an HTTP request response provided with delay at the TCP connection ESTABLISHING state and a different delay apply to data transfer during the ESTABLISHED TCP connection state. You can see how the delays valued configured on the Configuration test cases are matching with what get measured by Chrome Developer Tool:

Next features:

• add support for DNS, NTP, DHCP and other application level protocols
• integration of ssh-based control access Dependencies

This was checked on fresh Ubuntu 18.04 on VMWare virtual machine.

sudo apt update

sudo apt install git

sudo apt install libboost-all-dev

Installation of libtins

git clone https://github.com/mfontanini/libtins.git

apt-get install libpcap-dev libssl-dev cmake

mkdir build

cd build

cmake ../ -DLIBTINS_ENABLE_CXX11=1

make

sudo make install

sudo ldconfig

Clone integratio on home dir

git clone https://github.com/zupino/integratio.git

cd integratio

make

Also, remember to block RST packet from the server machine with the following iptable rule

NOTE This rule will check both RST and PSH flags, and drop only the RST=1 and PSH=0 In this way, we can block the RST from kernel, but let the RST PSH from test cases

iptables -A OUTPUT -p tcp --tcp-flags RST,PSH RST -j DROP
