Free internet secure access kit software for linux

Secure Messaging is a Web-based, alternative mail system for sending and receiving messages.

Use secure messaging to send and receive messages from a alternative web-based mail system. Using the secure messaging system no actual mail is transmitted through any 3rd party servers.

Only an optional message notice is sent to the recepient, the user needs to visit the site in order to read the message.

Normal SMTP mail can hit multiple servers and can possibly be read, stored, or changed anywhere within the process.

Setup secure messaging on an SSL enabled website to enhance the privacy even more.

Cheyenne Secure Web Server (SWS) is a comprehensive enterprise solution for Apache server. Cheyenne Secure Web Server combines http firewall, JAVA, PHP, PERL and a domain control system with Apache HTTPD platform.

Secure Back Door (SBD) is a tool that provides ultra-secure and minimal access to a computer, which allows you to run a single command based on a one time key. It is good if you dont want to have an SSH server running all the time, and only want to start it when needed. Because it has only a few lines of code, it is hoped that it will be less susceptible to security exploits than a program like SSH.
The protocol is detailed to an extent in the text file PROTOCOL, I will update it with more details as I have time, but the most important details are included already.
If you are a crypt analysis, or just like a challenge, I appreciate anyone who is willing to look through the protocol and/or code and point out possible security implications and flaws in design!
Enhancements:
- Fixed a few minor compiler warnings
- Updated license year to 2005
- Uncommented execution code in sbdd, so now sbdd will execute incoming commands
- Updated README documentation for compilation

Pre Make Kit (PMK) aims to be a BSD alternative to GNU autoconf, GNU libtool, and pkg-config. Pre Make Kit uses data files instead of scripts to limit the spreading of trojans in software packages.
Its designed to be easy to use for users and developers. For better portability and efficiency, all of the components are written in C. Requirements are a POSIX system, a C compiler, a POSIX shell, and a make tool.
Main features:
- Dependency configuration like autoconf (with partial compatibility mode).
- Compiler detection to set shared library flags.
- Architecture and cpu identification (support for x86 32 and 64 bits, IA64 and alpha).
- Internal pkg-config support (faster than calling pkg-config).
- Use a data file instead of a shell script that could hide trojans.

NoMachine NX Desktop Server is a cost-effective solution that enables any business to deploy centralized applications to thin clients, mobile and home workers, over any network connection, with astonishing speed and ease of use.
NX uses the power of the X-Window system to bring the network transparency of the Unix world to any operating system, including Windows and Mac OS/X. Additionally NX bridges the standard file and print services of the client, with the Unix file and print services of the server, so that, wherever you are, you can see the same applications and the same network resources.
Besides the native X-Window protocol, NX is able to translate, encrypt and compress industry standard protocols like the RDP protocol, used by Microsoft and Citrix, and the VNC protocol, used by a number of freely available tools, giving secure and fast access to the complete set of facilities made available inside a corporate network. The power of network computing has never been more affordable!
Main features:
- Deploys X11, RDP and VNC desktops securely over the Internet
- Provides unmatched performance, thanks to exclusive compression and aggressive caching
- Connects to XDMCP servers, Windows Terminal Services and Citrix MetaFrame servers on the backend, using the same client
- Seamlessly integrates single X11 applications with the native client desktop
- Lets users leave their applications running while disconnected and resume from any client on the network
- Lets applications access any file system on the client as if it were on the server
- Lets users cut and paste between local and remote applications
- Prints from the server to printers installed on the client
- Plays sound and multimedia produced by the remote application
- Integrates with your authentication infrastructure and directory service
- Supports industry standard SSL encryption and Transport Layer Security
- Fully integrates with SSH, avoiding the need for a further network access port
- Provides seamless integration with Web portals and corporate Intranets with one-click access to any application.
Enhancements:
- The new packages fix a number of problems such as the server Debian package not being fully Debian compliant, the NX server leaving a session in status Connecting when trying to suspend it, and the server being unable to find the xauth command on Solaris platforms.
