Vent Quickstart Guide

Getting Vent set up is quick and easy.

1. First, use pip to install the latest stable version of Vent:

  • Using pip:

    pip install vent && vent

Developer versions of Vent are available but may not be entirely stable.

  • Using Docker:

    docker pull cyberreboot/vent
    docker run -it vent_image_id
  • Using Git:

    git clone
    cd vent && make && vent

2. Now that Vent has started, let’s add, build, and start the core tools.

  1. In the main menu, press ^X to open the action menu
  2. Select Core Tools or press c
  3. Select Add all latest core tools or press i. Vent will now clone the core tools’ directories from CyberReboot/vent.
  4. Select Build core tools from the core tools sub-menu and use the arrow keys and the Enter key to press OK. It’s possible to choose which core tools are built using the Space key. Boxes with an X in them have been selected. Note that building the core tools takes a few minutes. Please be patient while Vent creates the images.
  5. Once the tool images are built, go back to the core tools sub-menu from main action menu and select Start core tools and hit OK. Much like Build core tools, it’s possible to select which core tools are started.

3. The core tools’ containers are up and running. Next, let’s add some plugins.

  1. From the action menu, Select Plugins or press p.
  2. Select Add new plugin or press a.
  3. For this quick start guide, we will use one of the example plugins provided from CyberReboot/vent-plugins. So just hit OK on the form.
  4. Press the Space key to choose the master branch and hit OK.
  5. Uncheck all the boxes except for /tcpdump_hex_parser and hit OK. Depending on the plugin, add times may vary so it is not unusual for long plugin add times.

4. Now we have a plugin that can process files with the extension .pcap.

  1. Now, at the Vent main menu, look for the field File Drop. This is the folder that Vent watches for new files.
  2. Move or copy a .pcap file into the path. Vent will recognize this new file and start tcpdump_hex_parser. Depending on the size of the .pcap file, it could take anywhere from a few seconds to minutes. You should see the jobs running counter increase by one and, after the plugin is finished running, the completed jobs counter will increase by one.

5. Let’s look at the results of the plugin using elasticsearch.

  1. From the action menu, select Services Running and select Core Services.
  2. Copy the address next to elasticsearch into the web browser of choice.
  3. On the main page, there should be a section with pcap with the results of the plugin.

Congrats! Vent is setup and has successfully recognized the pcap file and ran a plugin that specifically deals with pcaps. You can now remove the tcpdump_hex_parser via the Plugins sub-menu and create and install your own Custom Vent Plugins
