You have to download only one binary file corresponding to your architecture:
Lab simulation / "Hypervisor" mode
With the introduction of the 0.2.5 release, it is now possible to run the emulator as an "hypervisor" to start and control many virtual router instances simultaneously.
Dynagen (http://dyna-gen.sourceforge.net/), by Greg Anuzelli, is a front-end (written in Python) that makes lab simulation with the hypervisor very easy: it uses an INI-like configuration file to provision Dynamips emulator networks. It takes care of specifying the right port adapters, generating and matching up those pesky NIO descriptors, specifying bridges, frame-relay, ATM switches, etc. It also provides a management CLI for listing devices, suspending and reloading instances, etc. You can also distribute virtual instances across different servers to set up complex labs. To begin with Dynagen, you can consult this very complete tutorial (http://dyna-gen.sourceforge.net/tutorial.htm).
Dynagui (http://dynagui.sourceforge.net/) is a graphical front-end written by Yannick Le Teigner. It uses Dynagen to communicate with the hypervisor.
