Install and configure the Next-Gen WAF agent package

Now that you've downloaded the Ubuntu package repository, you can install and configure the Next-Gen WAF agent package:

  1. Run the following command to install the Next-Gen WAF agent package:
    $ sudo apt-get install sigsci-agent
  2. Create an empty agent configuration file in the following directory: /etc/sigsci/agent.conf.
  3. Add the agent keys for your site to the agent configuration file.
    accesskeyid = "AGENTACCESSKEYHERE"
    secretaccesskey = "AGENTSECRETACCESSKEYHERE"
  4. Save the agent configuration file.

Start the Next-Gen WAF agent

Now that you've installed and configured the agent package, you can start the Next-Gen WAF agent by running the following command:

$ sudo systemctl start sigsci-agent

Optionally, enable the agent auto-update service. The service checks the Signal Sciences package downloads site for a new version of the agent and updates the agent when a new version is available.
