Free secure vnc viewer software for linux

vt52vnc is a VNC viewer which can be used on prehistoric green monochromatic terminals called vdt52s, which are capable of vectorgraphics. vt52vnc is a VNC ( http://www.uk.research.att.com/vnc ) viewer, which can be used on old, green, monochromatic, prehistoric terminals labeled vdt52s, which are capable of vector graphics.The software is functional, but incomplete for now: it does not support compression, passwords and there are many ways to optimize the output.


Mouse:
As vdt52s does not have the mouse or any other pointing device, one of three unlabeled buttons near the numeric keypad have been used to act as mouse-lock. When you depress it, you can use the numeric keypad to move the mouse, and `+, `-, `., `enter, `0, and `5 as button 1,2,3 toggle and button 1,2,3 click.

Speed:
Based on my own experiences, I recommend the speeds 38400 and higher for "real work". The screen is drawn by rectangles. This is done to improve the reaction times, when the screen changes very often.

The software uses the XOR mode to actually draw the image, which can be improved using AND and OR mode in some cases. One can also imagine another optimizations for particular shapes. I will not add those optimizations, as the decisions are very memory-consumptive and after all, I dont want to implement some kind of prolog just to
choose the right one. If you want to improve it, let me know.

Colors:
The monochromatic translation is done by some bit of green color, which can be changed at the beginning of vncproto.c. If you want to make it better (implement some dithering or (better) the shape finding algorithm), let me know.

Why and how:
The work was inspired by mine never-ending desire for an X display on the "frog". Display drawings are based on the graphics library by Marek Zelem, which is, in turn, based on the documentation for vdt52s, as my work is based on vnc protocol documentation. Coded, of course, on vdt52s terminal with wrong Enter and Control. The sources are written to be easily extended.

Installation & running
1) edit Makefile to adjust some parameters,
vi Makefile
2) run `make
make
3) optionally install:
cp vt52vnc /usr/local/bin

Kbview - also known as the K Executable viewer - is a program that is designed to allow you to browse most executable formats. At present only ELF is supported.

This program is presently in pre-alpha state. While I have a general idea of how I want the development to proceed, and I am taking steps towards this goal (the release that is on this page is not the bleeding edge code), it is not there yet. I have released this code only as a proof of concept, and in the hope that anyone that finds it useful will contribute to it.

In short, not everything is implemented, and not everything that is implemented works. Also, not everything that is implemented is in its final state, even if it does work.

At present you can: Open executable files, get a list of the sections, view the string, symbol, and note tables (though note support is presently half-assed), and partial support for demangling the symbols is also provided.

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

Sysquake Viewer is an application which lets you load and manipulate interactively graphics developed with Sysquake.

Sysquake Viewer is much more limited than Sysquake LE, which supersedes it on Mac OS and Windows. We still provide it as a preview release for Linux on i386 and for Solaris on Sparc, until we have a robust beta version of Sysquake LE for Unix.

On Unix, files are archived with tar. In a terminal, type tar xzf sqviewer*tgz to un-archive them.

The preview is made available to you so that you can test it and provide feedback, and to have a broader range of platforms where SQ files can be viewed. It has no expiration date.

ThinkFree Viewer allows you to view ThinkFree or Microsoft Office word processing, spreadsheet, and presentation files without having any other office applications installed. After installing the appropriate Widget simply drag and drop files from your desktop, or copy and paste the Web URL into the ThinkFree Widget.

ThinkFree Widgets allows users to open email attachments with ease, and supports the following file formats: .doc, .rtf, .txt, .xls, .csv, .ppt, and .pps.

Browser History Viewer allows you to examine the contents of web browser history files and export the data.

Currently it supports Internet Explorer and Mozilla/Firefox.

Browser History Viewer meant to be a forensics tool. It meant to be a forensics tool.
