Free openvpn admin software for linux

Webmin OpenVpm Admin Module allows you to create static or CA-based VPNs through a Web interface.
Webmin is a valid web-based instrument for Linux/Unix system administrator. OpenVPN allows to create and manage VPN supplying wide possibilities of configuration.
Their union, with also the pressing necessity of having an efficient instruments of administration, has carried OPEN IT to develop a module of Webmin for OpenVPN.
The Open VPNadmin module is web-based and it can be used within Webmin. Witj this module you can:
- manage the Certificate Authority (CA)
- manage the VPNs and check the active connections
Enhancements:
- The device number (tun0, tun1, etc.) is automatically added and can be modified interactively.
- In the module configuration area the default server has been added as a new item.
- Tests for the validity of keys, servers, and clients were modified.
- New config files were provided for NetBSD and OpenBSD.
- The server static form was adapted to the Webmin skins.

OpenVPN is a full-featured SSL VPN solution which can accomodate a wide range of configurations, including remote access, site-to-site VPNs, WiFi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls (articles) (examples) (security overview) (non-english languages).
OpenVPN implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or 2-factor authentication, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface. OpenVPN is not a web proxy and does not operate through a web browser.
For a good conceptual introduction to OpenVPN, see the program notes for James Yonans talk at Linux Fest Northwest 2004 -- Understanding the User-Space VPN: History, Conceptual Foundations, and Practical Usage. See also OpenVPN and the SSL VPN Revolution by Charlie Hosner.
OpenVPN is an Open Source project and is licensed under the GPL. Commercial licenses are also available for firms who would like to redistribute OpenVPN with their own proprietary applications. Contact info@openvpn.net for more information.
Main features:
- tunnel any IP subnetwork or virtual ethernet adapter over a single UDP or TCP port,
- configure a scalable, load-balanced VPN server farm using one or more machines which can handle thousands of dynamic connections from incoming VPN clients,
- use all of the encryption, authentication, and certification features of the OpenSSL library to protect your private network traffic as it transits the internet,
- use any cipher, key size, or HMAC digest (for datagram integrity checking) supported by the OpenSSL library,
- choose between static-key based conventional encryption or certificate-based public key encryption,
- use static, pre-shared keys or TLS-based dynamic key exchange,
- use real-time adaptive link compression and traffic-shaping to manage link bandwidth utilization,
- tunnel networks whose public endpoints are dynamic such as DHCP or dial-in clients,
- tunnel networks through connection-oriented stateful firewalls without having to use explicit firewall rules,
- tunnel networks over NAT,
- create secure ethernet bridges using virtual tap devices, and
- control OpenVPN using a GUI on Windows or Mac OS X.

NG-Admin is designed for the content management of Databases, i.e. to browse, add, edit and delete data. It is somewhat similar to phpMyAdmin, but it is specialized to edit contents of the websites, not to edit the database structure. NG-Admin features are very easy to use and highly tunable.
NG-Admin was initially based on DASystem by Degtyarev Dmitriy, but because this project is no longer updated (last from 2003-11-28), we wrote lots of code completely new and added new functions and modules.
Main features:
- Easy to use, do not require training or special knowledge
- Easy to tune, just edit a single configuration file
- Multilingual support (English and German at the moment)
- Theme support (currently blue, red and a silver theme)
- Easy accessible menu always on the screen
- Automatical generation of menus and forms
- Supports MySQL
- Supports Browser upload of images and files
- Uploads can be made to local Directory or to a FTP-Server
- Cross-table data access
- Support for external modules
Enhancements:
- A new field named "timestamp_manual" has been added.
- As it says, it is to set values of timestamp fields manually.
- The error-messages are more detailed.
- By clicking "details" in the message box (available only on error), you will see a more detailed description about the error and why it occurred.
- The configuration file is easier to understand and has better comments sections.
- Minor fixes and speed improvements were made with colors and delete.
- A bug with local upload was fixed.

queue-admin provides a shell script for managing the mail queue of the qmail MTA.

queue-admin is a bash2 shell script for managing the mail queue of the qmail MTA.

It can provide a summarized list of the messages in the queue, optionally filtered by number or by whether a message is local or remote.

The messages themselves can be listed, viewed, or deleted by the same criteria.

It can also search for expressions within the messages, and can return the entire email or only the line where the expression was found.

The output is colorized.

SQL Admin is a Java client application to connect and send queries to different databases through JDBC.
SQLAdmin uses the brand new SWT Toolkit. The main idea is to create a multiplatform and multidatabase thin client. For example, you can connect to an Microsoft SQL Server from a Linux machine, or connect to a PostgreSQL/Linux server from a Windows machine using the same application.
Main features:
- Based on the SWT Tookit. Java applications can use the native Toolkit with a platform independant API. For example, SQLAdmin uses GTK2 in Linux
- Lightweight : The application itself is small, and the SWT provides a nice gui with a very small footprint
- Abstract JDBC driver backend. User should configure only basic parameters like server, port, and login without the need to know about Class names or JDBC URLs
- Graphical view of connections and database metadata such as schemas, tables and fields
- Multiple query execution. Also supports embedded comments on SQL Text
- Log window to view system messages and query results
- Table structure view
- Fast table rows view
