P-Synch is a commercial password management toolkit which provides automated password synchronization, password strength enforcement, password self-reset by authenticated users, and streamlined password reset by helpdesk. P-Synch is available for both internal use as well as for Internet-based deployments in B2B and B2C applications.
rsync is a replacement for rcp (and scp) that has many more features. It uses the "rsync algorithm" which provides a very fast method for remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.
PIKT is cross-categorical, multi-purpose software for monitoring and configuring computer systems, administering networks, organizing system security, and much more. PIKT is intended primarily for system monitoring, and secondarily for configuration management, but its versatility and extensibility evoke many other wide-ranging uses. PIKT consists of a sophisticated, feature-rich file preprocessor; an innovative scripting language with unique labor-saving features; a flexible, centrally directed process scheduler; a customizing file installer; a collection of powerful command-line extensions; and other useful tools.
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. Ganglia is currently in use on over 500 clusters around the world and has scaled to handle clusters with 2000 nodes.
Big Brother is a combination of monitoring methods. Unlike SNMP where information is just collected and devices polled, Big Brother is designed in such a way that each local system broadcasts its own information to a central location. Simultaneously, Big Brother also polls all networked systems from a central location. This creates a highly efficient and redundant method for proactive network monitoring.
