Free openvpn 2.0.9 software for linux

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.

KVpnc is a KDE frontend for various vpn clients. KVpnc project supports Cisco VPN (vpnc) and IPSec (FreeS/WAN, racoon).
vpnc is a replacement for the cisco VPN client and its used as client for the cisco3000 VPN Concentrator, FreeS/WAN (OpenS/WAN) is a IPSec client for Linux 2.4.x and racoon is a IPSec client for Linux 2.6.x and *BSD. It supports also PPTP (pptpclient) and OpenVPN.
You need vpnc >= 0.2-rm+zomb-pre9.
Note: translators still welcome. Kvpnc is currently translated to Bulgarian, Chinese, Dutch, German, Hungary, Italian, French, Portuguese Brazilian, Polish, Slovak and Spanish.
Main features:
- Easy to use KDE gui
- Docking in kicker
- Localized GUI:

Chinese
Dutch
French
German
Hungarian
Italian
Slovak
Polish
Portuguese Brazilian
Spanish

Kovpn is a simple OpenVPN GUI which is intended to fit end-users needs. Kovpn project runs without root privileges and can control the most important functions of openvpn:
- connect and disconnect
- username and password input
- private key passphrase input
- show status
- supports multiple openvpn connections
- Store username and/or passwords in kwallet
It requires some changes to your openvpn configuration file: You have to activate the management interface by adding these lines
management 127.0.0.1 11194
management-query-passwords
management-hold
You should choose localhost or 127.0.0.1 as host and a any unused port (e.g. 11194). You have to tell kovpn these host and port settings.
Please report any bug you find. It isnt well tested.
Enhancements:
- This release adds a simple DCOP interface (status report, connect, and disconnect).
- A resize bug in the configuration dialog has been fixed.
- Some options have been renamed to better reflect what they do.

VPN is a project that contains scripts to setup a VPN connection between several Unix systems in a very flexible way: a system can be VPN server and VPN client at the same time and a VPN server can serve multiple VPN clients.
This VPN software uses PPP over SSH, which is of course an obsolete method. A good alternative is OpenVPN.
Enhancements:
- Removed IPchains from up and down scripts.
- SSH_VERSION in configuration file.
- Support for FireTable package.

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.

vpn-shaper provides a dynamic traffic shaper for vpn, poptop, and similar programs, using iproute2.

vpn-shaper is a dynamic traffic shaper for openvpn, poptop, and similar programs, using iproute2. It allows shaping of traffic between many users conected to one server, and it supports different prioritiy schemes for different users and different types of traffic.

Trafic shaping uses the HTB qdisc. Prioritization uses l7-filter and ipp2p and some of the patch-o-matic extensions.

Classification of trafic in HTB classes is done by using the IPMARC patch-o-matic extension.

Ccaudio is a C++ class library for audio manipulation.

Ccaudio is a simple, highly portable, stand-alone, C++-based framework for manipulation of audio data.

Its goal is to be a C++ framework that as useful as audiofile or sndfile is for C programming, and to cover various generic and useful manipulations of audio data as well as audio file access. ccaudio compiles both under Unix and Win32 systems.
