How to connect an ossec agent installed on Virtualbox to host machine running on Cent

Hi Guys,

Am trying to install ossec IDS on my CentOS 6.3 machine.
Successfully installed it (Ossec Server on host machine). Have a Ubuntu 10.04 installation running on my virtual Box 4.2. Installed the ossec agent on the ubuntu.

I have all the agents of ossec installed on my host machine (Centos). Configure the agent, added the ip of the VBOX machine to the agent. Restarted the ossec service but still the agent installed in Virtual box is not connecting to the server installed on the host (CentOS 6.3).

Can any one please advise on this?

The out from host machine (CentOS )

OSSEC HIDS agent_control. List of available agents:

List of agentless devices:


Am sure the ip of the vbox is correct.

Imported the key from the server to agent (running on Vbox). but getting the following errors.
