A server administration tool using PHP, meant for rapid file access, and also to verify the server configuration and security. The script can be renamed and deployed on an unique known url, and offers password protection.. All dependencies, like images, js and css files, are included inside the same file, so that the script can run even on offline devices, like a local Raspberry Pi, or ESP32 microcontroller. The size of the script is bellow 1Mb, and i want to make it even smaller. To conclude, this script is also a repository of several hand made functions, organized in sections, meant for learning PHP and explore all PHP capabilities. You can learn, copy and use them on your own projects. Help the project with a donation: Will allow the view of two phpFileManager from diferent URLs on the same screen.

    m23

    m23

    Your linux deployment tool!

    m23 is a free software distribution system (license: GPL), that installs (via network, starting with partitioning and formatting) and administrates (updates, adds / removes software, adds / removes scripts) clients with Debian, (X/K)Ubuntu and LinuxMint. It is used for deployment of Linux clients in schools, institutions and enterprises. The m23 server is controlled via a web interface. A new m23 client can be installed easily in only three steps. Group functions and mass installation tools make managing a vast number of clients comfortable. The integration of existing clients (with .deb-based distributions) into the system is possible, too. Client backup and server backup are included to avoid data loss. With the integrated virtualisation software, m23 can create and manage virtual m23 clients, that run on real m23 clients or the m23 server. Scripts and software packages (for installation on clients) can be created directly from the m23 web interface.

    Debreate - Debian Package Builder

    Debreate - Debian Package Builder

    A utility for creating Debian packages (.deb)

    Debreate is a utility to aid in creating Debian (.deb) packages. Currently it only supports binary packaging (note that the term "binary package" is used loosely, as such packages can contain scripts & non-code items such as media images, audio, & more) for personal distribution. Plans for using backends such as dh_make & debuild for creating source packages are in the works. But source packaging can be quite different & is a must if you want to get your packages into a distribution's official repositories or a Launchpad Personal Package Archive (PPA). The latter from which Debreate is available.
