Deployment variables for Windows

For an agent to be fully deployed and connected to the Wazuh server it needs to be installed, registered and configured. To make the process simple, the installers can use variables that allow the configuration provisioning.

Below you can find a table describing the variables used by Wazuh installers on Windows, and a few examples on how to use them.

Option Description
APPLICATIONFOLDER Sets the installation path. Default C:\Program Files (x86)\ossec-agent.
ADDRESS Specifies the managers IP address or hostname. This option also accepts a list of IPs or hostnames separated by semicolons.
SERVER_PORT Specifies the managers connection port.
PROTOCOL Sets the communication protocol between the manager and the agent. Accepts UDP and TCP. Default is UDP.
AUTHD_SERVER Specifies the Authd IP address.
AUTHD_PORT Specifies the Authd connection port.
PASSWORD Sets the Authd password.
NOTIFY_TIME Sets the time between manager checks.
TIME_RECONNECT Sets the time in seconds until a reconnection attempt.
CERTIFICATE Specifies the certificate of authority path.
PEM Specifies the certificate path.
KEY Specifies the key path.
AGENT_NAME Designates the agent’s name. By default will be the computer name.
GROUP Assigns the specified group to the agent.
/l installer.log Generates a log of the installation process.
/l*v installer.log Generates a log of the installation process, including verbose messages.

Below there are some examples to install and register a Windows agent.

Registration with password:

wazuh-agent-3.9.3-1.msi /q ADDRESS="10.0.0.2" AUTHD_SERVER="10.0.0.2" PASSWORD="TopSecret" AGENT_NAME="W2012"

Registration with password and assigning a group:

wazuh-agent-3.9.3-1.msi /q ADDRESS="10.0.0.2" AUTHD_SERVER="10.0.0.2" PASSWORD="TopSecret" GROUP="my-group"

Registration with relative path to CA. It will be searched at your APPLICATIONFOLDER folder:

wazuh-agent-3.9.3-1.msi /q ADDRESS="10.0.0.2" AUTHD_SERVER="10.0.0.2" AGENT_NAME="W2019" CERTIFICATE="rootCA.pem"

Absolute paths to CA, certificate or key that contain spaces can be written as shown below:

wazuh-agent-3.9.3-1.msi /q ADDRESS="10.0.0.2" AUTHD_SERVER="10.0.0.2" KEY="C:\Progra~2\sslagent.key" PEM="C:\Progra~2\sslagent.cert"

The number “2” means that the file will be searched at the second occurrence of the “Progra” word, thus, the key and certificate would be searched at the folder “C:\Program Files (x86)”. In case this number was “1”, it would be searched at “Program Files”.

Note

To verify agents via SSL, it’s necessary to use both KEY and PEM options. See the verify hosts with SSL section.

Registration with protocol:

wazuh-agent-3.9.3-1.msi /q ADDRESS="10.0.0.2" AUTHD_SERVER="10.0.0.2" AGENT_NAME="W2016" PROTOCOL="TCP"

Warning

In Windows versions older than Windows Server 2008 or Windows 7, it’s necessary to run the ossec-authd program on the Wazuh manager with the -a flag or set the <ssl_auto_negotiate> option to yes on the auth configuration to avoid compatibility errors.
