Free https tunnel software for linux

HTTPTunnel is a simple client/server application for creating an HTTP tunnel between two machines, optionally via a Web proxy.
This is a small application for tunnelling an arbitrary TCP socket connection over HTTP. It can be used, for example, to tunnel traffic out from behind a restrictive firewall that only allows outgoing HTTP web connections.
The basic idea is that you run an instance of the HTTP Tunnel application locally in client mode, that then connects out to another instance that you run at the remote end of the tunnel in server mode.
You then connect to the local client end of the tunnel with the application whose traffic you wish to tunnel, and all communications are then wrapped in HTTP. The tunnel may also go via a HTTP proxy, either explicitly or transparently.
Enhancements:
- This release includes some major bugfixes and improvements in the tunneling error detection and retransmission code.
- It also introduces support for building and running under Cygwin.

Socks via HTTP provides a socks tunnel via HTTP.

Socks via HTTP is a program converting SOCKS requests into HTTP requests and tunnelling them through HTTP proxies if needed.

The SOCKS protocol allows programs to traverse firewalls on any port number and is used by many popular programs, like Napster, MSN Messenger, CRT(telnet client) and many others.

Many companies restrict firewall traversals only to HTTP requests, disabling SOCKS proxy.

Socks via HTTP provides a miniature SOCKS server for the SOCKS client, performing its connection through an HTTP proxy to a remote server, which establishes the real connection.

Socks via HTTP is 100% Java, and can run on any OS. It is entirely written in Java.

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.

Brutus is an Exchange connector and development framework that offers access to all of MAPI and therefore to all versions of Microsoft Exchange from version 5.5 onwards.
Brutus project is a complete wrapping of all of MAPI into a (large) set of CORBA interfaces. It enables any groupware client to integrate seamlessly into any organization with large Exchange deployments on an equal footing with MS Outlook.
Being based on CORBA, it is platform independent, and works equally well on Linux, the BSDs, Windows, or wherever there is a CORBA implementation available.
Enhancements:
- Logging of failure cases was generally improved.
- SSLIOP support has been removed.
- SSLIOP is no longer needed as Lorica will add CORBA firewall support as well as an SSLIOP tunnel between Brutus Server and any client application.
- MAPI object property scrambling was added.
- This is a new feature that makes it possible for an administrator to content scramble specific users.
