In order for Eucalyptus to function in your local environment, be sure to prepare your network.
To prepare your network, perform the tasks listed in this section.
Verify connectivity between the machines you’ll be installing Eucalyptus on. Some Linux distributions provide default TCP/IP firewalling rules that limit network access to machines. Disable these default firewall settings before you install Eucalyptus components to ensure that the components can communicate with one another.
