Installing the agent

• If Alpine is being run in a Docker container, you must start the container.
• Copy the agent keys for the site that you want the agent to be able to access. You will use the agent keys when configuring the Next-Gen WAF agent package.

If you are running Alpine in a Docker container, complete the following steps:

1. Run the following script to add the package repository:

   $ apk update
   $ apk add wget
   $ wget -q https://apk.signalsciences.net/sigsci_apk.pub ; mv sigsci_apk.pub /etc/apk/keys/
   $ echo https://apk.signalsciences.net/3.19/main | tee -a /etc/apk/repositories && apk update

2. Verify the downloaded key contains the proper key by running the following command:

   $ openssl rsa -pubin -in /etc/apk/keys/sigsci_apk.pub -text -noout

   If the downloaded key contains the proper key, the expected output looks like the following:

To add the Debian 11 - Bullseye package, run the following script:

$ sudo apt-get update
$ sudo apt-get install -y apt-transport-https wget gnupg
$ wget -qO - https://apt.signalsciences.net/release/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/sigsci.gpg
$ sudo echo "deb [signed-by=/usr/share/keyrings/sigsci.gpg] https://apt.signalsciences.net/release/debian/ bullseye main" | sudo tee /etc/apt/sources.list.d/sigsci-release.list
$ sudo apt-get update

To add the Ubuntu 24.04 - Noble package, run the following script:

$ sudo apt-get update
$ sudo apt-get install -y apt-transport-https wget gnupg
$ wget -qO - https://apt.signalsciences.net/release/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/sigsci.gpg
$ sudo echo "deb [signed-by=/usr/share/keyrings/sigsci.gpg] https://apt.signalsciences.net/release/ubuntu/ noble main" | sudo tee /etc/apt/sources.list.d/sigsci-release.list
$ sudo apt-get update

1. Run the following command to install the Next-Gen WAF agent package:

   $ sudo apk add 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.

If you are running Alpine in a Docker container, run the following command to start the Next-Gen WAF agent:

$ /usr/sbin/sigsci-agent

If you are running Alpine in a VM or on a bare-metal server, run the following command to allow the agent to start on reboot:

$ sudo rc-update add sigsci-agent default

Then, start the agent by running any of the following commands:

$ sudo service sigsci-agent start
$ sudo rc-service sigsci-agent start
$ sudo /etc/init.d/sigsci-agent start
