Open Source Linux Systems Administration Software

smartmontools contains utility programs (smartctl, smartd) to control/monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (S.M.A.R.T.) built into most modern ATA and SCSI disks. It is derived from smartsuite.

Collectl is a light-weight performance monitoring tool capable of reporting interactively as well as logging to disk. It reports statistics on cpu, disk, infiniband, lustre, memory, network, nfs, process, quadrics, slabs and more in easy to read format.

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. Supports clusters up to 2000 nodes in size.

Manage node sets, node groups and execute commands on cluster nodes in parallel. Provides an event-based Python library to improve administration of large compute clusters or server farms. Command line tools: clush and nodeset included.

ClusterSSH controls a number of xterm windows via a single graphical console window to allow commands to be interactively run on multiple servers over an ssh connection.

m23 is a free software distribution system (license: GPL), that installs (via network, starting with partitioning and formatting) and administrates (updates, adds / removes software, adds / removes scripts) clients with Debian, (X/K)Ubuntu and LinuxMint. It is used for deployment of Linux clients in schools, institutions and enterprises. The m23 server is controlled via a web interface. A new m23 client can be installed easily in only three steps. Group functions and mass installation tools make managing a vast number of clients comfortable. The integration of existing clients (with .deb-based distributions) into the system is possible, too. Client backup and server backup are included to avoid data loss. With the integrated virtualisation software, m23 can create and manage virtual m23 clients, that run on real m23 clients or the m23 server. Scripts and software packages (for installation on clients) can be created directly from the m23 web interface.

openQRM is a web-based open source datacenter management and hybrid cloud computing platform that integrates flexibly with existing components in enterprise data centers. Releases available at https://github.com/openQRM/openqrm-community. Please visit http://www.openqrm-enterprise.com for latest 5.3 free Community Release. Includes important security updates, bugfixes and enhancements especially for KVM and Cloud plugin. openQRM abstracts Virtualization and supports the following virtualization technologies: KVM, XEN, Citrix XenServer, VMWare ESX & LXC. The Hybrid Cloud Connector in openQRM supports a range of private or public cloud providers to extend your infrastructure on demand via Amazon AWS, Eucalyptus or OpenStack. openQRM automates provisioning, virtualization, storage and configuration management, and it takes care of high-availability.

Lucie enables parallel network installation of large numbers of nodes from one single administration server. It is designed to be scalable and efficient, so a complete Linux cluster can be built from scratch in a short amount of time.

Reliable group communication based on IP multicast and configurable protocol stack

rshd is a multithreaded daemon service that listens for connections on port 514 (tcp port for the shell/cmd protocol), runs commands passed by clients and sends back the results.

This software (written in C using Glib/Gtk+) allows you to set up a High-Availability fault tolerant cluster, for Linux, Solaris, and other UX systems. It includes heartbeat mechanism (network and/or disk), a monitoring process.

Linux Cluster Manager is designed as a beowulf cluster setup and management tool. LCM can run bulk commands, give real time performance and status monitoring, search running processes, and provide system imaging at a file or block level over the network

The Distribulator: Distributed Computing For The Rest Of Us. This is an SSH-based command execution and file transfer utility that includes support for batch, console, and shell integration modes, multiple server enviornments, and full audit logs.

Whatsup is a cluster node up/down detection utility. This project has moved to Github: https://github.com/chaos/whatsup

OpenBAM is a Business Activity Monitoring(BAM) application for Operations Managers in service organizations who are constantly trying to figure out what's effecting their business by trying to co-relate data from multiple systems.

The Maui Scheduler is a tool to to extend the capabilities of existing resource manager systems such as PBS, SGE, Loadleveler, and so forth. It provides powerful tools for managing and optimizing clusters systems and features to enable effective use of t

OSCAR (Open Source Cluster Application Resources) is a snapshot of the best known methods for building, programming, and using clusters. It consists of a fully integrated and easy to install software bundle designed for high performance cluster computing

PuSSH is Pythonic, Ubiquitous SSH, a Python wrapper/script that runs commands in parallel on clusters/ranges of linux/unix machines via SSH, ideally where SSH is configured to use Kerberos, RSA/DSA keys, or ssh-agent as to avoid password authentication.

chainssh is a shell script to smplify the ssh login via multiple sshgateways/firewallgateaways. e.g. connect from homehost via sshgateway to a clusternode with one command.

build and manage beowulf-style cluster -remote reboot and power control -remote and centralized cluster management Web-based GUI.

Acelet-Scheduler with SuperScheduler and SuperWatchdog is a Java task scheduler with daemon and GUI for system and application job scheduling, can schedule tasks in a distributed environment. Holiday adjustable. Works out-box. See http://www.acelet.com

Job Accounting and User and Project managment for Clustered Computing using Perl, Apache, and MySQL. Designed to be extensible, it processes logs from currently PBS, OpenPBS and Maui2. It also contains a web frontend for User and Project Managment

BTime synchronizes the system clocks on Linux computers that form a cluster, and ensures that all computers in the cluster have approximately the same time (usually within microseconds).

CACM = Client Access to Cluster Manager manage access via ssh for user to a cluster (or a computer) via SSH key and a Web calendar Interface. The web site manage all users. An user can reserve the cluster via the web site. A daemon generate a SSH-key-p.

CatBox is designed to help experts and amateurs to configure their Linux/FreeBSD/OSX/Solaris-based system in a simple, yet effective way. CatBox is also based on a client-/server-model.
