Linux Cluster Manager is a graphical tool for managing multiple Linux systems from a central location. Meant primarily for Beowulf style clusters, it has many useful features for general system administration and even some non Linux specific possibilities like block level imaging.

Imaging with LCM is quick and easy as each node has its IP and hostname changed ready for boot as an independant node preloaded with all of your applications. Using a file based image, items can be changed such as the target device, the file system capacity, or even the file system type. Imagine requiring a new partition on boot disks already filled across hundreds of machines. It is a simple property change, re-image the node(s), and you are ready to go.

Image creation can be done from a running system or LCM can remote power on a node through WOL, PXE boot it, collect an image, and power off the node when complete.

All operations are simple point and click, no command line options to remember (these are optional), or complicated setup.

Here are some key features of "Linux Cluster Manager":
Easy to use GUI for all operations
Real time status information for all nodes
Connect to individual nodes via a user specified protocol (ssh, rsh, rlogin ,etc)
Report on running processes across the cluster

Imaging Features

Imaged nodes have IP and hostname information changed automatically, just image and boot
Block level system imaging (can be used for any x86 based operating system)
File level system imaging
Wake on LAN for imaging
Preconfigured for PXE boot of clients
Images can be customized - target device changed, file system size, file system type

Monitor Features

Real time status monitoring for all nodes, CPU and Network
Scrolling, scalable graphs
View all nodes or a subset you are interested in

Scripting Features

Run scripts across the cluster or on select nodes without a client agent
Connects via a user selected protocol with secure authentication
Command line or GUI interface
Can be incorporated into external scripts

Scripting Features Requirements:

ssh, rsh, rlogin, or telnet

Imaging Features Requirements:

tftp, nfs, and dhcp servers

What's New in This Release:
This focuses on imaging improvements, now supporting 64 bit clients throughout the imaging process.
User commands or scripts can now be included for custom deployments.
Support for clients using udev is also included, along with the latest network drivers.
