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.

Ptunnel is an application that allows you to reliably tunnel TCP connections to a remote host using ICMP echo request and reply packets, commonly known as ping requests and replies. At first glance, this might seem like a rather useless thing to do, but it can actually come in your help in some cases.
Setting: Youre on the go, and stumble across an open wireless network. The network gives you an IP address, but wont let you send TCP or UDP packets out to the rest of the internet, for instance to check your mail. What to do? By chance, you discover that the network will allow you to ping any computer on the rest of the internet. With ptunnel, you can utilize this feature to check your mail, or do other things that require TCP.
Main features:
- Tunnel TCP using ICMP echo request and reply packets
- Connections are reliable (lost packets are resent as necessary)
- Handles multiple connections
- Acceptable bandwidth (150 kb/s downstream and about 50 kb/s upstream are the currently measured maximas for one tunnel, but with tweaking this can be improved further)
- Authentication, to prevent just anyone from using your proxy

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.

Cubehub is a simple UDP over TCP tunnel application written in Java. It is designed to help people behind a firewall to connect through a TCP connection and play Quake and other UDP-based games.
SOCKS 4 and 5 are protocols that are supposed to allow users to send data through a firewall. However, they only work like this if the SOCKS server is on the firewall itself. Whilst TCP/IP traffic is frequently permitted through firewalls, UDP/IP (required by most online games) is often blocked. When a SOCKS 5 server relays UDP data (SOCKS 4 does not support UDP), the packets are simply relayed, there is no tunnelling involved.
This application provides a solution, tunnelling the data being relayed by a SOCKS server over one or (for better gaming performance) multiple TCP connections to help applications and games to work from behind a restrictive firewall.
Main features:
- Socks 4/5 server
- TCP and UDP tunnelling over single or multiple TCP connections
- Resilience against individual connection dropping

StdioTunnel project allows you to tunnel arbitrary TCP connections through any shell access connection.

If the connection provides a clear 8-bit data path and allows you to start programs, you can use it with StdioTunnel.

It tunnels TCP connections in much the same way SSH does, but is useful in particular cases where SSH port forwarding is disabled, and it does not require running or changing the configuration of any server processes on either side of the connection.

Once StdioTunnel handshakes, the connection you used to initiate it is no longer available. The local StdioTunnel process will ignore further input. The connection is shut down when you kill the StdioTunnel process at either end.

All that is required for StdioTunnel to make a connection is that the standard input and output of the remote side appear to be connected through an 8-bit clear channel to the standard input and output of the process started by the local side. ssh with the -e none option to turn off the escape character works quite nicely as the connecting process.

Please note that using ANY software, StdioTunnel included, to work-around firewall restrictions may make systems on either side of the firewall more vulnerable to any number of attacks. StdioTunnel may have bugs that make such vulnerabilities even worse. The user takes sole responsibility for any adverse consequences of using this software.

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.

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
}
}
