Free user software for linux

ext2fuse is an implementation of the ext2 filesystem in user space, using the FUSE library. Uses might include as a base for filesystem projects, for FUSE or e2fsprogs testing, and for situations when a kernel mode filesystem is not appropriate.

Webmin is a web-based interface for system administration for Unix.

Using any browser that supports tables and forms, you can setup user accounts, internet services, DNS, file sharing and so on.

TuxUsers application is a user management KControl module and stand alone utility.
It allows very wasy user accounts management:
- User creation, deletion and modification.
- Change KDM start icon.
- Predefined groups for new users to ease new user permissions.
- Thinkfinger fingerprint reader suported to add easily fingerprint auth. for your system.

Cornfed SIP User Agent is a Session Initiation Protocol (SIP) based softphone for your IBM-compatible Personal Computer running the Linux operating system.
The Cornfed SIP User Agent allows you to make Internet phone calls using an Advanced Linux Sound Architecture (ALSA) or Open Sound System (OSS) sound card with speakers and microphone as your telephone handset.
Main features:
- Supports SIP (RFC 3261), SDP (RFC 2327), and RTP (RFCs 3550 and 3551)
- Automated detection of Residential Gateways using Network Address Translation (NAT)
- Supports Digest authentications for registrations and outbound INVITEs
- Support for loose proxy routing using Record-Route and Route headers
- Handles forking of outbound INVITEs by proxies
- Supports re-INVITEs for changes to media transport
- Supports G.711 mu-Law and a-Law voice codecs

The Cornfed SIP User Agent is provided free of charge for personal use for users of the Linux operating system. The program is provided as a binary distribution only. The Cornfed SIP User Agent is specifically designed with embedded and mobile wireless devices in mind.
Development is under way to bring this client to other platforms. If you are interested in licensing this technology for your commercial application, please contact Cornfed Systems at 410-404-8790.
Enhancements:
- Minor bug fixes.
- Changed readline functionality to used raw input rather than cooked mode.

- Disabled removal of registration on client exit.

Gwyddion is a modular program for SPM (scanning probe microscopy) data visualization and analysis. Primarily it is intended for analysis of height fields obtained by means of scanning probe microscopy techniques (AFM, MFM, STM, SNOM/NSOM), however it can be generally used for any other height field and image analysis (learn more about Gwyddion features).
This project is Free and Open Source software, covered by GNU General Public License. It aims to provide multiplatform modular program for 2D data analysis that could be easily extended by modules and plug-ins. Moreover, the status of free software enables to provide source codes to developers and users, which makes the further program improvement easier.
Gwyddion works on GNU/Linux, Microsoft Windows, Mac OS X and FreeBSD operating systems on common architectures, all systems can be used also for developement. Its graphical user interface is based on Gtk+ and port to other systems supported by Gtk+ should be possible.
Enhancements:
- The guide was brought up to date with Gwyddion 2.7.
- The coverage is now almost 100%; only a few obscure features remain underrepresented.
- The introductory part was extended. GNU sed is now required to build the guide from DocBook sources.

tk_docapp project is a small GUI for mounting devices and ACPI energy monitoring under NetBSD.

User of other *nix operating systems can only use the mount option.

LDAP User Management System (LUMS) provides a set of basic LDAP API functions for PHP and a strong configuration language. The project can then be used to create Web services or can be used in any PHP script.
The language allows the administrator to define LDAP object types along with their corresponding attributes.
Each attribute may be defined as required as multivalued with a type (string, binary, dn, telephone, mail, etc.) and can be user inserted, constant, auto incremented, or function created. Attribute uniqueness is supported.
It exports the following LDAP operations:
- function LUMS_ldap_search($L_binddn,$L_bindpassword,$L_basedn,$L_scope,$L_filter,$L_attrs_array)
Returns an $info object with the search results or a string with an error
- function LUMS_ldap_add_entry($L_binddn, $L_bindpassword,$L_object_type,$L_entrydn,$L_entry_info)
Returns 0 for success or string with error
- function LUMS_ldap_change_password($L_binddn, $L_bindpassword,$L_entrydn,$L_newpassword)
Returns 0 for success or string with error
- function LUMS_ldap_modify_entry($L_binddn, $L_bindpassword, $L_object_type, $L_entrydn, $L_change_info)
Returns 0 for success or string with error
- function LUMS_ldap_delete_entry($L_binddn, $L_bindpassword, $L_object_type, $L_entrydn)
Returns 0 for success or string with error
- function LUMS_ldap_rename_entry($L_binddn, $L_bindpassword, $L_object_type, $L_entrydn, $L_newrdn, $L_newparent, $L_deleteoldrdn)
Enhancements:
- Add a virtual attribute which is not stored on ldap but can be useful when creating other attribute values
- Add mapping between an indexing attribute value to other attribute values
- Fix a few typos
- Perform the same checks for all value types not just uservalue
- Lower case all passed attribute names
