I developed a tool that I founded very useful to do work on multiple nodes from a central server
I use it to run tasks on my ossec agents from the ossec server. It is based on some ideas and similar tools in the net.
In order to run the tool on your agents you will need a ssh key on the ossec central and the public key on the agents as .ssh/authorized_keys
As always "Use the force read the code"
