Check_MK is a complex addon for Nagios/Icinga and consists of three subprojects. The check and inventory system Check_MK is a general purpose Nagios plugin for retrieving data. It adopts a new approach for collecting data and obsoletes NRPE, check_by_ssh, NSClient, and check_snmp. It features a significant reduction of CPU use on the Nagios host and automatic inventory of items to be checked, and is especially useful with larger Nagios installations. "MK Livestatus" gives immediate and fast access to live and historic Nagios status data. It's a supported backend for many addons including NagVis, NagiosBP, and Thruk. "Check_MK Multisite" is a feature complete replacement for the Nagios GUI, and uses MK Livestatus as a backend. It is very fast, and supports efficient distributed monitoring.
The klish is a framework for implementing Cisco-like command-line interfaces on Unix systems. It is configurable through XML files. "Klish" stands for "Kommand Line Interface SHell". The klish is a fork of clish-0.7.3. The original clish was developed by Graeme McKerrell. The klish adds some new features, but is compatible (as much as possible) with clish's XML configuration files.
Bashinator is a bash shell script framework. It provides flexible and powerful message handling that lets you print to stdout, log (to syslog or a logfile), and mail messages with a single message function. Exhaustive information is included in messages to ease debugging. This information includes timestamps, message severity, source file, line numbers, and function names. A facility for tracing the function call stack is provided. Sub-command output can be logged by capturing the stdout/stderr of external commands to a dedicated temporary logfile. The framework also provides lockfile handling.
Enterprise Audit Shell (EAS) allows organizations to centrally audit and report UNIX shell access. Unlike Sudosh, the audit logs are sent to a centralized archive and reporting server. Client server authentication and encryption is handled by SSL. It was specifically designed for enterprise, commercial use.
repla can turn any command into a shell. It does this by prepending the name of a command to each commandline before executing it. It can also add lists of arguments which are often needed, either prefixed or affixed to the commandline. It really shines with vcs or build commands, such as git, svn, hg, make, configure, etc.
HOMER is a robust, carrier-grade, scalable SIP capturing system and monitoring application with hEP, IP Proto4 (IPIP) encapsulation, and port mirroring/monitoring support right out of the box, ready to process and store large amounts of signaling with instant searches, end-to-end analysis, and drill-down capabilities for ITSPs, VoIP providers, and trunk suppliers using SIP signaling.
getxbook is a collection of tools to download books from websites. There are tools to download from Google Books' "book preview", Amazon's "look inside the book", and Barnes and Noble's "book viewer". There is an optional GUI written in Tcl/Tk, and some shell scripts using OCR to create plain text or searchable PDFs and DjVu files from the downloaded books.
prll is a utility for parallelizing the execution of shell functions. It provides a convenient interface for parallelizing the execution of a single task over multiple data files or any other kind of data that you can pass as a shell function argument. It is meant to make it simple to fully utilize a multicore/multiprocessor machine. prll is designed to be used not just in shell scripts, but also in interactive shells. To make the latter convenient, it is implemented as a shell function. Shells are not very good at automatic job management, so prll uses helper programs, written in C. To prevent race conditions, System V Message Queues are used to signal job completion. Standard output is buffered and Semaphores are used to prevent interleaving.
