Free secure vnc software for linux

Secure Login provides a login extension similar to Operas Wand login.

It uses the built-in password manager, but deactivates the prefilling of login forms.
Instead, you are now able to login with one click or a keyboard shortcut (ALT+N).
Just add the Secure Login toolbar button to your toolbar, or use the provided statusbar icon.
If you hover over one of the icons, a tooltip is shown, displaying the login url and the number of available logins (users).
For more than one user or login forms on the current page a selection prompt is displayed on login.
You have the option to play sound notifications (*.wav) for found login data on the current page or when logging in.
All the options can be changed using the Secure Login settings menu or the statusbar icon context menu.

Secure Login provides you with a number of Security enhancements and helps protecting you from phishing:

Disabling the prefilling of login forms prevents malicious JavaScript code to automatically steal your login data.
This is due to the fact that no login data is inserted in form fields before the user clicks on the login button or logs in using the keyboard shortcut.
To make sure you login to the right website, the second level domain of the login url is compared to the second level domain of the current page.
If they do not match a dialog prompt is displayed before login.

SecureLogin provides you with an optional setting to protect you from all JavaScript code during login.
This can prevent cross-site scripting (XSS) attacks without having to deactivate JavaScript completely.
If you enable this option, your login data will never be inserted in any form fields nor will the login form be submitted.
Instead your credentials will be sent to the login page using internal Firefox methods.
Not all login forms will work this way, e.g. not those using JavaScript routines.
Therefore, you can add such websites to an exception list.

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

Secure Data Manager project is a manager for passwords and other private data.

Main features:
- Many great features and more coming each month based on user feedback!
- No limit to how you use the product or how often!
- Trusted since you and everyone else can see the code that protects your passwords -- keeping the application clear of any trojans or bad business practices.
- Open source -- so if you know how to write code, you can add any feature you want!
- Free.

VNC stands for Virtual Network Computing.
The two computers dont even have to be the same type, so for example you can use VNC to view an office Linux machine on your Windows PC at home. VNC is freely and publicly available and is in widespread active use by millions throughout industry, academia and privately.
RealVNC is a UK company founded in 2002 by a team from the world-leading AT&T Laboratories in Cambridge. The company was established to commercially develop, enhance and promote VNC, the innovative remote access software with a widespread international user base.
VNC (Virtual Network Computing) software makes it possible to view and fully-interact with one computer from any other computer or mobile device anywhere on the Internet. VNC software is cross-platform, allowing remote control between different types of computer. For ultimate simplicity, there is even a Java viewer, so that any desktop can be controlled remotely from within a browser without having to install software.
VNC has a wide range of applications including system administration, IT support and helpdesks. It can also be used to support the mobile user, both for hot desking within the enterprise and also to provide remote access at home, or on the road. The system allows several connections to the same desktop, providing an invaluable tool for collaborative or shared working in the workplace or classroom. Computer support within the geographically spread family is an ever popular use.
The open source version of VNC has been freely available since 1998, and more than 50 million copies of the software have been downloaded. The software has also appeared on numerous magazine cover disks, and for several years all popular versions of Linux have included VNC. It is in active use by many millions in industry, commerce, education and at home. Virtually all Fortune 500 companies use VNC, and installations of VNC across thousands of workstations are commonplace.
Enhancements:
- FIXED: Security vulnerability.

Quinti Secure Contact Form is a contact form for Web pages that is not vulnerable to robots who would abuse such forms for sending spam.
It uses both JavaScript field validators and CAPTCHA for verifying the validity of the sender. Quinti Secure Contact Form is easy to install and configure, and uses valid XHTML 1.1.
I have been attacked thousand times by spammers from my contact form, they use robots and take advantage of certain vulnerabilities of the mail forms to send their spam, and fill up my mailbox up to such an extent that they make your mail practically useless.
There are two ways of tackling this problem: Introducing a CAPTCHA validated through JavaScript, as i explain later.
And introducing certain functions in PHP that prevent these attacks, as you will see in the examples below
At the moment, go to the problem.
Main features:
- Invulnerable secure antispam contact form,
- JavaScript field validator in php (to insert multi-language variables and other variables, if you wish)
- Prevent spammers from using your form to send garbage, guaranteed.
- CAPTCHA to avoid Javascript validated Spam
- Easy to install and configure
- Valid XHTML 1.1

Remote Secure Command System project is a remote asynchronous and secure command system based on a file configuration.

• Enhanced NTFS support: NTFS-3G driver updated to version 1.2506

Requirements:

• Be x86 compatible
• Have at least 256MB of RAM
• Be able to boot from a CD

c-ares project is a C library that resolves names asynchronously.
Enhancements:
- ares_save_options, ares_destroy_options, ares_process_fd, and ares_parse_ns_reply were added.
