eve-ng

This is an EVE-NG fork of just the html directory to add functionality.

Fucntionality is currently incomplete, use at own risk.

Installation

Installation can be done ontop of an existing 2.0.79 EVE-NG install with the following

cd  /opt/unetlab
git clone https://github.com/breakintheweb/eve-ng.git
mv html htmlbak
mv eve-ng html
mv html/install.sh ./
./install.sh

The install script does the following; backup /etc/network/interfaces to interfaces.bak installs docker.io modifies docker startup script and configuration modifies openvswitch to fix issue modifies apache2 startup to fix issue add new /etc/network/interfaces for ovs

Uninstallation

Uninstallation should be as easy as restoring the html directory and interfaces file

Capture to docker node feature

Firstly, you need to pull a docker image with vnc. The below image should work

docker pull danielguerra/wireshark-vnc

Next, you will need to create a docker node with this image inside your lab.

Once the image is running you will need to add the container id to includes/.config The format is labid_tenantid_nodeid

You can also find it by using docker ps from the cli.

Note: The script which adds the capture inteface dosent have rights to modify the ovs db. I need to fix this but for the time being you can chmod 777 /var/run/openvswitch/db.sock or chown www-data:www-data /var/run/openvswitch/db.sock
