CALDERA has both a Server and an Agent, the requirements for each are different.
The agent is installed on each computer that will be involved in the emulation exercise. The agent supports 64 bit versions of Windows 7 and higher.
The server must be installed on a computer that is accessible over the network to all agents. The server will run on either Windows or Linux; however, it needs access to a compiled Windows binary, CraterMain.exe, so that it is able to serve this file to the agents. If running the server on Linux, CraterMain.exe can be built on a Windows machine and copied to the Linux machine, or a precompiled executable may be downloaded from here.
See :doc:`installation` for information on installing the Server and Agents.
CALDERA operates in a Windows Enterprise network environment. At a minimum this will contain a Domain Controller running Windows Server 2008 R2 through 2016 and two Windows Enterprise computers joined to that domain.
See :doc:`environment_setup` for more information on creating a Windows Enterprise test environment
An Internet connection is required to install CALDERA, however once installation is complete an Internet connection is no longer required. It is possible to install CALDERA without Internet by manually copying CALDERA's dependencies to the install server. Contact CALDERA's developers for more information.
