OpenArm is an implementation of the Open Group's Application Response Measurement (ARM) standard. It provides a complete implementation of the ARM 4.0 Java interfaces, as well as ARM agent functionality that allows you to record your transaction events as log4J logging events, JMS messages, SNMP traps, JMX notifications, or as records in a relational database.
epto is a small library and framework for industrial strength shell script programming with sh. It features convenient error handling, tracing, logging, option handling, documentation template, process level transaction safety (sort of), and more. If one is used to shell programming, it takes less than five minutes of learning to start using it (see the crash course in the README file).
nexB OpenAssets is a tool for inventorying, managing, and monitoring applications, software, hardware, networks, and generally any IT asset. It is designed so that system administrators, IT, and finance can determine what they have, how it is configured, what it is used for, and how much it is being used, so that informed decisions can be made. It complements existing network management software, integrates with a growing number of protocols and tools, and features no-agent discovery and inventory, configuration management including dependencies and correlation, monitoring, and reporting. It makes extensive and innovative use of XML, Xpath, and Xquery.
Elektra is a universal hierarchical configuration store, similar to GConf and the Windows Registry. It allows programs to read and save their configurations with a consistent API, and allows them to be aware of other applications' configurations, leveraging easy application integration. While architecturally similar to other OS registries, Elektra does not have most of the problems found in those implementations. Elektra includes a library, an API, and commandline and GUI tools for administration tasks.
The tcb suite implements the alternative password shadowing scheme on Openwall GNU/*/Linux (Owl) which allows many core system utilities (passwd(1) being the primary example) to operate with little privilege. It is being made available separately from Owl primarily for use by other distributions. This package contains three core components of the tcb suite: pam_tcb (a PAM module which supersedes pam_unix), libnss_tcb (the accompanying NSS module), and libtcb (a library for accessing tcb shadow files, used by the PAM and NSS modules as well as by user management tools on Owl).
crypt_blowfish is an efficient implementation of a modern password hashing algorithm, based on the Blowfish block cipher, provided via the crypt(3) and a reentrant interface. It is compatible with bcrypt as used in OpenBSD. It is adaptable to future processor performance improvements, allowing you to arbitrarily increase the processing cost of checking a password while still maintaining compatibility with your older password hashes. The hashes it produces are several orders of magnitude stronger than traditional Unix DES-based or FreeBSD-style MD5-based hashes.
pyNMS is a set of Python modules for network management, network testing, systems management, and general use. It contains a nearly complete implementation of SNMPv2c, a SMI/MIB package, and a MIB "compiler". There are many others, such as a telnet/console access class, XML tools, an IPv4 class, etc. There is, unfortunately, little documentation, and not everything works properly yet, but they work well enough to be useful for many things.
MX4J is an Open Source implementation of the JMX technology (JSR 3) and of the JMX Remote API (JSR 160). It aims to create JMX-related tools such as adaptors, connectors, and utility MBeans. JMX is the Java standard used to create manageable server-side applications, and it is used as a base architecture for many popular J2EE application servers, such as JBoss, BEA, Geronimo, etc.
