For this exercise, we'll be using the countdown_to_ecstasy cookbook. About Handlers. Use a handler to identify situations that arise during a chef-client run, and then tell the chef-client how to handle these situations when they occur.
Exception/Report Handlers Exception and report handlers are used to trigger certain behaviors in response to specific situations, typically identified during a chef-client run. An exception handler is used to trigger behaviors when a defined aspect of a chef-client run fails.A report handler is used to trigger behaviors when a defined aspect of a chef-client run is successful.
Both types of handlers can be used to gather data about a chef-client run and can provide rich levels of data about all types of usage, which can be used later for trending and analysis across the entire organization. Exception and report handlers are made available to the chef-client run in one of the following ways: Ruby Tutorial with Code Samples. Chef Server. Learning Chef - Part 1 - Nathen Harvey.

From The Open Source Backup Wiki (Amanda, MySQL Backup, BackupPC) Amanda has been tested on Mac OS X Panther (10.3), Tiger (10.4), Leopard (10.5) and Snow Leopard (10.6). With Panther, the built-in tar does not record extended filesystem attributes (resource forks, finder flags, ACLs, and so on), so users who want to be able to restore those attributes will need to do some extra work (see below).
Knife client — Chef Docs. Networking - Vagrant Documentation. In order to access the Vagrant environment created, Vagrant exposes some high-level networking options for things such as forwarded ports, connecting to a public network, or creating a private network. The high-level networking options are meant to define an abstraction that works across multiple providers. This means that you can take your Vagrantfile you used to spin up a VirtualBox machine and you can reasonably expect that Vagrantfile to behave the same with something like VMware. You should first read the basic usage page and then continue by reading the documentation for a specific networking primitive by following the navigation to the left.
In some cases, these options are too high-level, and you may want to more finely tune and configure the network interfaces of the underlying machine. Most providers expose provider-specific configuration to do this, so please read the documentation for your specific provider to see what options are available. Knife configure — Chef Docs.
