Amahi: Powerful, Simple Home Server

The Amahi Linux Home Server makes your home networking simple. We like to call the Amahi servers HDAs, for “Home Digital Assistants.” Each HDA delivers all the functionality you would want in a home server, while being as easy to use as a web browser.
The core functionality available in the base Amahi HDA install includes:
•Protect Your Computers Back-up all your networked PCs simply and easily on your home network. If one of your PCs “dies” you can easily restore it!
•Organize Your Files Access, share and search your files from any machine on your network, making it easy to share and find your photos, music and videos.
•Internet Wide Access Automatically setup your own VPN so you can access your network from anywhere: safely and securely.
•Private Internet Applications Shared applications like calendaring, private wiki and more to come, will help you manage your home and your family!

Cobbler: An open source installation server

Cobbler is a Linux installation server that allows for rapid setup of network installation environments. It glues together and automates many associated Linux tasks so you do not have to hop between lots of various commands and applications when rolling out new systems, and, in some cases, changing existing ones.

With a simple series of commands, network installs can be configuredsc for PXE, reinstallations, media-based net-installs, and virtualized installs (supporting Xen, qemu, KVM, and some variants of VMware). Cobbler uses a helper program called ‘koan’ (which interacts with Cobbler) for reinstallation and virtualization support.

Cobbler is a small and lightweight application (about 15k lines of Python code). It tries to be extremely simple to use both for very small and very large installations — as well as easy to work on, extend, and hack. It avoids being “enterprisey” (as in complicated) whenever possible, but is highly useful in all sorts of enterprises by having a lot of advanced features and doing small things to save a large amount of time in repeated tasks.

Cobbler can also optionally help with managing DHCP, DNS, and yum package mirroring infrastructure — in this regard, it is a more generalized automation app, rather than just dealing specifically with installations. There is also a lightweight built-in configuration management system, as well as support for integrating with configuration management systems like Puppet. Cobbler has a command line interface, a web interface , and also several API access options. That sounds like a lot, but it’s really pretty simple. New users may like to start with the web app after doing the initial setup steps on the command line (cobbler check; cobbler import) as it will give them a good idea of all of the features available. Advanced features don’t have to be understood all at once, they can be incorporated over time as the need for them arises.
