Transparent Caching ftp proxy server - frox

Frox is a transparent FTP proxy that runs under Linux and *BSD. It should also work on other UNIX OSes that use ipfilter.

Frox Features:
* active - passive mode conversion for data connections.
* It supports caching of FTP downloads, either through a local cache, or by redirecting connections through another proxy such as squid.
* Downloads may be transparently scanned for viruses (through an external scanner).
* Optional non-transparent proxy support by logging in with user@host:port.
* Options to bind to a specific interface, chroot, and drop priveleges for security.
* Written with security in mind, default setup runs as a non-root user in a chroot jail.

Install Flash 8 or Flash CS3 on Ubuntu Linux - Wine

Wine is an Open Source implementation of the Windows API on top of X and Unix. Wine provides both a development toolkit for porting Windows sources to Unix and a program loader, allowing many unmodified Windows binaries to run on x86-based Unixes.

Install the latest version of wine:
Ubuntu and Ubuntu derivatives (such as Kubuntu) obtain software from packages which are stored in repositories. Ubuntu's default repository includes Wine, however if you want to stay up to date with the latest Wine package you can use WineHQ's by following these instructions, open up the terminal (Applications > Accessories > Terminal) and type following command to install latest version of wine

sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update
sudo apt-get install wine

How to Remove old and un-used Kernel from System and Grub Menu - Ubuntu Linux

The kernel is a piece of software that, roughly speaking, provides a layer between the hardware and the application programs running on a computer. In a strict, computer-science sense, the term 'Linux' refers only to the kernel - the software that Linus Torvalds wrote in the early 90s.

All the other pieces you find in a Linux distribution - the Bash shell, the KDE window manager, web browsers, the X server, Tux Racer and everything else - are just applications that happen to run on Linux and are emphatically not part of the operating system itself.

UI Application to take System Backup and Snapshot - TimeVault

Backing up data can be difficult, especially when you only want to copy files that changed since the last backup. It can be even more troublesome when you have to remember to start the process manually,or you have to delete old backups to make room for new ones. Because of these difficulties, some people decide not to back up data at all, and feel the pain when they accidentally delete the wrong file or their system crashes. TimeVault is a backup utility for Ubuntu that addresses these problems.

TimeVault is an UI application that performs a function similar to Apple's TimeMachine. It makes automated snapshots of (selected parts of) the file system. You can roll back to a previous version of a file or directory, or just view it the way it was when the snapshot was taken. Snapshots are protected from accidental deletion or modification since they are read-only by default. The super-user can delete intermediate snapshots to save space, but files and directories that existed before or after the deletion will still be accessible

Get Security Information about your PHP environment - PhpSecInfo

PhpSecInfo provides an equivalent to the phpinfo() function that reports security information about the PHP environment, and offers suggestions for improvement. It is not a replacement for secure development techniques, and does not do any kind of code or app auditing, but can be a useful tool in a multilayered security approach.

* It is not a replacement for secure coding practices
* It does not audit PHP code
* It is not comprehensive test for either your hosting environment or your web application
* It is not the "final word." PHPSecInfo identifies *potential* problems and offers suggestions for improvement.
