Free https tunnelling software for linux

tcptunnel is a simple TCP tunnel written in Perl.

Also is a versatile tcp tunnel. The tcptunnel uses:
- tunnelling through a firewall or proxy
- redirecting tcp connections to other ports or machines
- debugging tcp connections in-place
- packet sniffing

The tcptunnel listens on local port < port > and when a connection is made it connects the other end of the tunnel as follows:
a) With no proxy specified, it connects the other end
to < srvport > on < srv >.
b) With a proxy, it connects to < srvport > on < proxy >.
It then directs the proxy to telnet to < srv >, and then it connects the ends of the tunnel.

JSecureTunneling provides a Java SSH client for tunnels management.

SecureTunneling is a Java SSH client that is entirely oriented toward the management of SSH tunnels, offering the ability to establish secure and permanent tunnels to a remote SSH server transparently, just like a simple network connection.

The key features are: auto-reconnection, connection monitoring, connection triggers, tunneling changes on-the-fly, and profile management.

TunnelVision creates an encrypted VirtualPrivateNetwork, or VPN, between two Tunnel Vision-capable sites on the Internet.
TunnelVision creates an encrypted VirtualPrivateNetwork?, or VPN, between two Tunnel Vision-capable sites on the Internet. Realistically, that means sites with a Linux server running TunnelVision or with a WorldvisionsWeaver? or NetIntegrator acting as their Internet gateway.
TunnelVision requires a Linux 2.2.x kernel or later for running properly. Were sorry about that, but we wanted to use the new features.
Enhancements:
- Also known as 0.70pre2.
- Lots of underlying library changes as WvStreams v2 was debugged.
- A new way of handling strings and lists makes things prettier.
- Several bug fixes resulting from the use of our new stresstest program.
- Connections regenerate themselves after the 10-minute idle timeout.
- All known bugs have been eliminated.

prtunnel is a program that can tunnel TCP/IP connections in a variety of ways, including through HTTP and SOCKS5 proxy servers. Some if its possible uses include:
- Tunneling TCP connections from client programs to a remote server through an HTTP or SOCKS5 proxy (useful if youre behind such a proxy and want to use a program that doesnt have native proxy support)
- Tunneling TCP connections from SOCKS-capable client programs through an HTTP or SOCKS5 proxy
- Tunneling TCP connections from an IPv4 client program to an IPv6 server and vice-versa
- Forwarding TCP connections
- Running as a simple SOCKS proxy server
prtunnel project was developed and used under Linux and BSD-based operating systems.
Enhancements:
- A bug that would cause malloc(0) to be called in some situations (which could cause problems on some systems) has been fixed.
- The server timeout, if specified, is now set before the proxy server successfully connects to the remote server, which will prevent the program from hanging if the proxy does not respond to the client.

ssh tunnel on demand provides a script that creates an SSH tunnel on demand.

ssh tunnel on demand is a script that makes it possible for a user to create an SSH tunnel to a server and connect to it without needing an account on the box or any experience with SSH.

It was written for users that wanted to connect to Usermin at a remote site. Users enter information into a Web form and the server then connects an SSH tunnel to the remote Usermin server and redirects the browser through the tunnel.

Tunnel project is a simple game involving a ball going down a tunnel.

Tunnel is a game in which you control a capsule going down a tunnel, shooting other balls in the way. In the process you should pick up power-ups and avoid collisions with enemy balls coming your way.

During the game, you can fire at other balls. They break into fragments which can damage your capsule, so beware.

If the game is too slow on your computer, try using a lower resolution, either using command line options or by modifying the options files.

Tunnel is free software released under the GPL.

HttpdBase4J is an embeddable Java web server framework that supports HTTP, HTTPS, templated content and serving content from inside an archive.

The classes are easy to extend as they utilize the Hollywood dont call us, well call you principle to allow the user to overide the framework behaviour during all the different phases of the HTTP transaction.

Note:HttpdBase4J uses the Java 6 com.sun.net.httpserver classes so it wont currently work under earlier versions of Java.

Usage Examples:

The simplest use case is to create an embedded web server on port 8088 with its home directory at htdocs in the local filesystem and a root url at / ie / maps onto htdocs:

homeDir = new java.io.File("./htdocs");
httpd = new FileHttpd(homeDir, 10); // Creates a server with a threadpool of 10
httpd.setLogger(System.err); // Log to console
httpd.start(8088, "/");

Creating a HTTPS server equivalent the the HTTP server above requires passing a keystore and password to start. Passing null will generate a certificate free keystore if you only need the encryption capabilities of HTTPS and not the certificate capability:

httpd = new FileHttpd(homeDir, 10);
m_httpd.start(8089, "/", keystore, password);

Serving content from inside an archive or from a jar or zip in the Java classpath requires creating an ArchiveHttpd instance instead of a FileHttpd. To serve content located in a jar or zip in the class path you need only specify the resource directory in the classpath where the content islocated, for example:

httpd = new ArchiveHttpd("/resources/htdocs", 10);
httpd.start(8088, "/");

To serve content from within a specific archive specify the archive as a Java File when constructing the ArchiveHttpd:

httpd = new ArchiveHttpd(new File("content.zip"), "/resources/htdocs", 10);
httpd.start(8088, "/");

Creating web content using templates is also supported. Currently only the StringTemplate library (http://www.stringtemplate.org) is is supported but it should be relatively easy to create user derived classes for other template implementations. To create an HTTP embedded web server on serving templated content from resources/htdocs in the classpath and having a template file handler (A Java class implenting the Templatable interface that is used to fill the templates) in net.homeip.donaldm.test.templates.

httpd = new ArchiveHttpd("resources/htdocs", 10);

StringTemplateHandler stHandler = new ArchiveStringTemplateHandler(httpd,
"net.homeip.donaldm.test.templates");

httpd.addHandler(".st", stHandler); // .st extension = template files
httpd.start(m_port, "/");

The HTTP transaction handling can be customized at any point by overiding any of the methods in the HttpHandleable interface or by overiding onCreateRequestHandler in Httpd in order to provide your own request handler. A simple example of overiding HttpHandleable methods:

httpd = new TestOverideHttpd(m_homeDir, 10);
httpd.start(m_port, "/");

class TestOverideHttpd extends FileHttpd
{
public HttpResponse onServeHeaders(long id, HttpExchange ex, Request request)
{
//Create or amend content
}
public InputStream onServeBody(long id, HttpExchange ex, Request request)
{
//Return amended or created content
}
}
