When most IPv6-capable computers join a network they attempt to automatically find a router on the network so they can figure out what addresses to use, how to set up routing, and so forth. On BSD systems like my router, the rtadvd(8) program manages the router’s side of this exchange. While rtadvd is rather flexible, its configuration file is frustratingly terse and its documentation assumes the reader has a fair amount of knowledge already.
For IPv4, my network uses DHCP to hand...

This is a short story on how a UI developer at Eucalyptus was able to use Eucalyptus to save his time on development of Eucalyptus.
The agenda of the day is to set up Travis CI for the latest Eucalyptus user console, Koala. Quoted from Wikipedia, “Travis CI is a hosted, distributed continuous integration service used to build and test projects hosted at GitHub.” In other words, we want to set up an automated service hook on Koala’s GitHub repository so that whenever developers...
Eucalyptus 4.0 is the next major release of Eucalyptus. One of the exciting features of this release is Object Storage Gateways (OSG). It uses Riak CS as scalable storage backend. It also works with Walrus as storage backend. Object Storage Gateway first came out as tech preview in 3.4 release. To use Riak CS with OSG it is required to have an existing Riak CS setup.
In this post we will setup a minimal Riak CS setup to work with Eucalyptus OSG. For this demo I am using a Eucalyptus 4...
