== How to add an agent without any keyboard input ==

By default, to add an agent from server side, you must provide your agent
information  to `manage_agents` program, by using its interactive mode.
This is really tedious if you have many servers / agents to add. Luckily,
you can use following environment variables as responses

     | variable name          | value   | description          |
     +------------------------+---------+----------------------+
     | OSSEC_ACTION           | A/a     | add an agent         |
     | OSSEC_AGENT_NAME       | string  | name of agent        |
     | OSSEC_AGENT_IP         | CIDR    | ip address of agent  |
     | OSSEC_AGENT_ID         | integer | max length = 8       |
     | OSSEC_AGENT_KEY        | string  | base64 format        | (*)
     | OSSEC_ACTION_CONFIRMED | y/Y/n/N | y -> confirmed       |

    (*) OSSEC_AGENT_KEY is used only on agent (when key is being imported)

Please note that it's your duty to ensure that name, ip,... of agent are
valid. Otherwise, the program will fall back to interactive mode. In most
case, you should ensure that you new agent has an unique name/id. You can
simply know that by using `manage_agents -l` to list all known agents.

For more details, please refer to OSSEC document
    https://www.ossec.net/docs/manual/agent/agent-management.html

== Notes ==

You can also use some tools (`expect`) to send strings to `manage_agents`,
instead of using the above environment variables.
