Free started software for linux

Supervisor is a client/server system that allows its users to control a number of processes on UNIX-like operating systems. It was inspired by the following:
- It is often inconvenient to need to write "rc.d" scripts for every single process instance. rc.d scripts are a great lowest-common-denominator form of process initialization/autostart/management, but they can be painful to write and maintain. Additionally, rc.d scripts cannot automatically restart a crashed process and many programs do not restart themselves properly on a crash. Supervisord starts processes as its subprocesses, and can be configured to automatically restart them on a crash. It can also automatically be configured to start processes on its own invocation.
- Its often difficult to get accurate up/down status on processes on UNIX. Pidfiles often lie. Supervisord starts processes as subprocesses, so it always knows the true up/down status of its children and can be queried conveniently for this data.
- Users who need to control process state often need only to do that. They dont want or need full-blown shell access to the machine on which the processes are running. Supervisorctl allows a very limited form of access to the machine, essentially allowing users to see process status and control supervisord-controlled subprocesses by emitting "stop", "start", and "restart" commands from a simple shell or web UI.
- Users often need to control processes on many machines. Supervisor provides a simple, secure, and uniform mechanism for interactively and automatically controlling processes on groups of machines.
- Processes which listen on "low" TCP ports often need to be started and restarted as the root user (a UNIX misfeature). Its usually the case that its perfectly fine to allow "normal" people to stop or restart such a process, but providing them with shell access is often impractical, and providing them with root access or sudo access is often impossible. Its also (rightly) difficult to explain to them why this problem exists. If supervisord is started as root, it is possible to allow "normal" users to control such processes without needing to explain the intricacies of the problem to them.
- Processes often need to be started and stopped in groups, sometimes even in a "priority order". Its often difficult to explain to people how to do this. Supervisor allows you to assign priorities to processes, and allows user to emit commands via the supervisorctl client like "start all", and "restart all", which starts them in the preassigned priority order. Additionally, processes can be grouped into "process groups" and a set of logically related processes can be stopped and started as a unit.

TraxAuth is a web-based user account registration, management and maintenance system, written in Python. This project was started in order to provide the codeTRAX users with a way to register and manage their accounts.

The project is being co-developed by CodeTRAX.org and G-Loaded.eu and is released under the terms of the Apache License version 2.

Heimdal is an implementation of Kerberos 5, largely written in Sweden (which was important when we started writing it, less so now). Heimdal project is freely available under a three clause BSD style license.
Other free implementations include the one from MIT, and Shishi.
Enhancements:
- Several bugs in iprop were fixed.
- Platforms without dlopen are now supported.
- RFC3526 modp group14 is now included by default.
- [kdc] database = { } entries are now handled without realm = stanzas.
- krb5_get_renewed_creds and kaserver preauth were fixed along with other bugs.

Postfix project is Wietse Venemas mailer that started life as an alternative to the widely-used Sendmail program.

Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.

Gammu+ project can be named as next step in evolution. Author of this www started to think about new project written in C++ using classes somewhere in August 2002.
Some first source was written in October 2003 (16-10-2003 can be taken as start date), but a little faster progress started in December 2003.
Main features:
- full modular construction
- using Unicode everywhere
- using all modern possibilities available in C++ language
- breaking problems available because of using structures with declared size of members (in other words: using everywhere structures allocated dynamically)
For now there is available command line version. In the future there will be GUI and shared library for using in own applications.
Enhancements:
- This release adds support for SMS with WAP push, Nokia phonebook, Nokia calendar, and Nokia todo entries.
