One of our customers uses a piece of software that depends on the MAC address of the running system. Unfortunately this application misbehaves when used on Amazon EC2 cloud computing. Therefore we have written a small piece of software called fakemac.

We’re glad to announce that we’ve published our set of EC2 scripts on GitHub! The repository contains current versions of the code described in our previous two blog posts on EC2.

By default, instances created on Amazon EC2 will have a randomly assigned IPv4 address, which is why we’ve written a script to automatically create DNS entries in PowerDNS for instances managed through EC2.

In order to make use of Amazon EC2 to its full potential, it is important that we can quickly spawn Debian installations that are automatically configured using Puppet. We accomplish this by creating our own Kumina-branded Amazon Machine Image (AMI).
