The tcb suite implements the alternative password shadowing scheme on Openwall GNU/*/Linux (Owl) which allows many core system utilities (passwd(1) being the primary example) to operate with little privilege. It is being made available separately from Owl primarily for use by other distributions. This package contains three core components of the tcb suite: pam_tcb (a PAM module which supersedes pam_unix), libnss_tcb (the accompanying NSS module), and libtcb (a library for accessing tcb shadow files, used by the PAM and NSS modules as well as by user management tools on Owl).
The Distributed Concurrent Versioning System (DCVS) extends the well-known version control system CVS and the file distribution and synchronization program CVSup with functionality to distribute CVS repositories with local lines of development and handle synchronization of the distributed repositories automatically in the background. Development lines (branches) are owned by a repository server, repository servers efficiently update each other via CVSup, and CVS ensures correct server use on checkin and branch creation.
sysklogd-sql is a port of the sysklogd daemon that can log data to a MySQL or PostgreSQL database running either on the same machine or a remote database server. The SQL configuration is done in the standard syslog.conf file for easy administration and configuration. Also included is a set of sample PHP scripts to query the data from the syslog database. In a large environment, you can set up a central logging server, or configure a secure syslog environment that will make it very difficult to tamper with the syslog data.
NovaDNS is a program to manage many BIND zonefiles (domains) from a user-friendly, Web-based GUI. The zones are stored in a MySQL database, maintained through the Web GUI, and are periodically generated from the database. User information is also stored in a MySQL database. Users can only maintain their own domains, while administrators can maintain all domains (zone files) on the server. This program is especially useful for large ISPs with many customers.
Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their TCP personality can be adapted so that they appear to be running certain versions of operating systems. Honeyd enables a single host to claim multiple addresses on a LAN for network simulation. It is possible to ping the virtual machines, or to traceroute them. Any type of service on the virtual machine can be simulated according to a simple configuration file. Instead of simulating a service, it is also possible to proxy it to another machine.
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.
