Debian Cluster Components (DCC) is a toolset for building, managing, and deploying high-performance Linux clusters in a simple, admin-friendly way. The suite consists of the following system components: System Installation Suite, C3 suite, TORQUE queueing system, OpenLDAP, and Ganglia. When this set of Debian packages is installed on a stand-alone Debian machine, it provides the full functionality of a cluster's master node. The packages are available in a public APT repository.
DenyHosts is a script intended to help Linux system administrators thwart ssh server attacks. DenyHosts scans an ssh server log, updates /etc/hosts.deny after a configurable number of failed attempts from a rogue host is determined, and alerts the administrator of any suspicious logins.
OtheRSync is a program for the automatic, efficient, and safe synchronization of two machines over a network. It's efficient (using compression and incremental changes), safe (uses ssh, is fail-safe, and makes backups of deleted files by default), uses parallel processing, and supports feedback through the commandline prompt. It is built on top of rsync. New or changed files are synchronized, and files that have been deleted on one machine are deleted on the other machine. OtheRSync can resume without becoming broken or dangerous after an interruption or an error.
