Free https tunnel linux software for linux

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

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

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.

Phrealon is a bootable linux CD based on Slackware Linux 8.0 (now 9.0)designed to allow the easy imaging of multiple workstations.

It utilizes the udpcast set of Linux tools to accomplish this.

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.

Powered by Linux is a KDM theme created after a wallpaper of the same name. It was tested on KDE 3.5.6.
