Simple Package Manager (SPM) is intended to operate in a way similar to existing package managers (apt, dpkg, Pacman, etc.). Instead of supporting a centralized package repository, SPM allows remote packages to be downloaded and installed automatically, given their URL. This allows a developer to package and distribute software via a package management system without having to worry about the many different formats and Linux distribution repositories.
Rerun is a lightweight tool-building framework useful to those implementing management procedure with shell scripts. It will help you organize your implementation into well-defined modular interfaces. Collections of management modules can be archived and delivered as a single executable to facilitate team handoffs. Using the "stubbs" module, rerun will even facilitate unit tests. When users execute rerun module commands, rerun can record execution data into log files which can later be replayed.
Ambit uses Bash brace expansion to expand and list hostnames or commands. Ambit is first and foremost meant to be a general purpose hostlist enumerator for use by other applications or scripts. Ambit can be used to manage HostGroups from the context of a user, a system, or a network. Ambit is also able to enumerate and execute commands that contain expandable elements. Commands passed to Ambit are expanded into separate statements and executed synchronously. This means Ambit can expand and execute just about anything on the command-line and often works in situations where Bash brace expansion would probably fail.
rules2mrtg is a tool that creates MRTG data traffic graphs derived from iptables's internal traffic statistics for the local machine for every configured IP number/ethernet alias. You can also define ports or port ranges to be monitored per IP address. This avoids problems with using SNMP and aliased interfaces.
