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. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.
agedu scans a directory tree and produces reports about how much disk space is used in each directory and subdirectory, and also how that usage of disk space corresponds to files with last-access times a long time ago.
In other words, agedu is a tool you might use to help you free up disk space. It lets you see which directories are taking up the most space, as du does; but unlike du, it also distinguishes between large collections of data which are still in use and ones which have not been accessed in months or years – for instance, large archives downloaded, unpacked, used once, and never cleaned up. Where du helps you find what's using your disk space, agedu helps you find what's wasting your disk space.
Arronax is a program to create and modify starters (technically: .desktop files) for applications and locations (URLs).Arronax can be used as a standalone application or as a plugin for Nautilus, the default file manager of the Gnome and Unity desktop environments.
The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer.

tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.
When tmux is started it creates a new session with a single window and displays it on screen. A status line at the bottom of the screen shows information on the current session and is used to enter interactive commands.
Icinga is an enterprise grade open source monitoring system which keeps watch over networks and any conceivable network resource, notifies the user of errors and recoveries and generates performance data for reporting. Scalable and extensible, Icinga can monitor complex, large environments across dispersed locations.
Icinga is a fork of Nagios and is backward compatible. So, Nagios configurations, plugins and addons can all be used with Icinga. Though Icinga retains all the existing features of its predecessor, it builds on them to add many long awaited patches and features requested by the user community.
task spooler is a Unix batch system where the tasks spooled run one after the other. The amount of jobs to run at once can be set at any time. Each user in each system has his own job queue. The tasks are run in the correct context (that of enqueue) from any shell/process, and its output/results can be easily watched. It is very useful when you know that your commands depend on a lot of RAM, a lot of disk use, give a lot of output, or for whatever reason it's better not to run them all at the same time, while you want to keep your resources busy for maximum benfit. Its interface allows using it easily in scripts.
sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.Probes for HTTP, SSL, SSH, OpenVPN, tinc, XMPP are implemented, and any other protocol that can be tested using a regular expression, can be recognised. A typical use case is to allow serving several services on port 443 (e.g. to connect to ssh from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port.
A DHCP Server assigns IP addresses to client computers. This is very often used in enterprise networks to reduce configuration efforts. All IP addresses of all computers are stored in a database that resides on a server machine.This tutorial will explain how to install and configure DHCP server in ubuntu 12.10 server.

If you want to mount VirtualBox drive image (vdi) in Ubuntu 12.04/12.10 use vdfuse.This Fuse module uses the VirtualBox access library to open a VirtualBox supported VD image file and mount it as a Fuse file system. The mount point contains a flat directory containing the files EntireDisk, Partition1 .. PartitionN. These can then be loop mounted to access the underlying file systems.
GLPI stands for “Gestionnaire libre de parc informatique”, GLPI is the Information Resource Manager with an additional Administration- Interface.

In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache, MySQL and PHP) server up and ready to go. This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.The LAMP option means you don’t have to install and integrate each of
the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual
applications. Instead, you get increased security, reduced time-to-install, and reduced risk of misconfiguration, all of which results in a lower cost of
ownership.Currently this installation provide PostgreSQL database, Mail Server, Open SSH Server,Samba File Server, Print Server, Tomcat Java Server,Virtual
Machine Host,Manual Package selection,LAMP and DNS options for pre-configured installations, easing the deployment of common server configurations.
MATE is a fork of Gnome 2.It provides an intuitive and attractive desktop to Linux users using traditional metaphors.This tutorial will explain how to install/remove MATE desktop environment in ubuntu 12.04(precise)/11.10 (Oneiric).
