Usermin is a Web interface that can be used by any user on a UNIX system to easily perform tasks like reading mail, setting up SSH, or configuring mail forwarding. It can be thought of as a simplified version of Webmin designed for use by normal users rather than system administrators.
svclean is a set of utilities for enhancing svscan and supervise. With these tools, you get clean shutdown (i.e. services are guaranteed to be stopped before their loggers, so no logs are lost) and supervised logging of svscan's and supervise's output (so if the last-resort logger is killed, it can be restarted). These features are practically necessary for running svscan as process 1, but are useful even when svscan does not run as process 1.
Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. It is the simplest solution to numerical computing and visualization in the domain of C/C++. It supports the ISO 1990 C Standard (C90), major features in C99 (complex numbers, variable length arrays or VLAs, type generic functions, long long data type, etc), classes in C++, and extensions to the C language like nested functions, string types, etc. It can be embedded in other applications and hardware and used as a scripting language. C/C++ code is interpreted directly with no compilation to intermediate code. It supports Linux, Windows, MacOS X, Solaris, HP-UX, and FreeBSD.
Originally based off the program qmail-masq, qmail-masq-user uses qmail and qmail-qfilter to change the From: address of outgoing emails to almost any combination of username, domain, or both. The configuration allows you to specify domain catch-alls, user catch-alls, email catch-alls, specific combinations of users and/or domains, and much more.
The DAP daemon runs entirely as a non-privileged user and sends regular updates of the server status to a specified set of peers in a cluster. You can specify any number of information elements, such as uptime, networkdevice counters (packet/octet), logged in users (via utmp), load averages, and memory/swap usage.
Dpsyco is a automated system to distribute system configurations to several computers. It is written mainly for the Debian distribution but should be portable (without too much difficulties) to other distributions or Unixes as well. It consists of a number of shell scripts to perform the desired actions. With it you can handle users, add ssh-public-keys, patch the system, update things using cfengine, install files (overriding other package files), and more.
Xjob is a GUI task scheduler. The drag-and-drop GUI makes it easy to create and maintain complex job routines, and visualize each job as it is created. Xjob has proven itself under the most rigorous testing scenarios and industry applications. It can handle jobs ranging from simple FTP to integrated deployment of external programs and applications for complex jobs. A typical Xjob process retrieves files from FTP servers and e-mails from POP or IMAP servers. It then processes the files and sends them to a local disk or other servers via FTP or e-mail. Users can schedule multiple processes for Xjob as hourly, daily, weekly, or monthly jobs. It is completely fault tolerant and ensures that valuable data is never lost in the case of unexpected downtime. If any computer shuts down or is unavailable, Xjob's process verification ensures that the job will continue once the host computer is restarted. It runs on all systems that support Java, and provides a Web-based administration interface to monitor and control jobs. A built-in Web server displays statistics for current jobs via the Web.
