Free user account control software for linux

Useful Traffic Accounting Dragon is a traffic accounter that actually gives useful information about traffic instead of stupidly counting incoming/outgoing packets.
Dragon accounts traffic by user, program and timestamp and puts this information into useful correlation.
Dragon is implemented as a Perl script for the backend, using /etc/passwd to automatically get information about user accounts, /proc/net/ to get information about open connections and /proc/ to get information about running processes and which processes currently use which network connection.
All this information can be combined so you can actually see what user caused which traffic using what program and when it happened.
All this information is acquired automatically so the minimal configuration necessary is to tell dragon where it can find its MySQL database.

Simple Xmms Control is a a simple SuperKaramba theme that provides XMMS control. Icons are from nuoveXT icon theme.

All suggestions are welcome!

Azureus Speed Control is a project that enables automatic configuration of your upload limit. This addresses the problem of implicit additional upload when Azureus downloads with high speed, which can lead to connection choking. This is a problem specially for users with low upload bandwidth like German ADSL users.

If your download rate increases, the upload limit will be reduced by a value that can be customized. If the download rate decreases, the upload limit will increase again.

Device Control Device is a platform independent remote telescope and device control program compatible with the INDI standard (see http://indi.sourceforge.net/).

This program is a client (a user interface) and provides functions to control devices connected to a remote system that is running an INDI server.

The features and the structure of the GUI are similar to the Kstars INDI client. The only advantages are support for Windows and lower resource requirements.

XMMSd web control plug-in allows XMMS to be controlled with a Web browser. It makes it easier for languages like PHP to remotely control XMMS.

eXtended Account Management System is a PHP-based application suite made for managing electronic mail accounts on multiple domains in a virtual hosting environment.

- or user@domain2.tld) will be delivered to one mailbox.
- Autoreply (out of office) support

XAMS manages these domains and user accounts in a database, entirely separate from your Unix system environment.
XAMS ties together and integrates with these packages to provide a coherent virtual hosting solution for e-mail:
- Exim, a flexible mail transfer agent (MTA) with an intuitive and flexible configuration system
- The Courier IMAP/POP server for mailbox access
- MySQL, a powerful, free database server, used for storing domain and account information.
XAMS does not currently manage FTP or HTTP servers. The XAMS graphical user interface is written in PHP, runs on top of Apache, and produces XHTML 1.1 compliant pages.
Enhancements:
- Several bugs were fixed regarding Exim configuration, SQL, and more.
