PHP Shell is a shell wrapped in a PHP script. It's a tool you can use to execute arbiritary shell-commands or browse the filesystem on your remote Web server. This replaces, to a degree, a normal telnet-connection. You can use it for administration and maintenance of your Web site using commands like ps, free, du, df, and more.
g4u ("ghost for unix") is a boot-floppy/CD that allows one to easily clone PC hard disks by using FTP. This is often done to deploy a common setup on a number of PCs. The floppy/CD offers two functions: it uploads the compressed image of a local hard disk to an FTP server, and then it can retrieve that image via FTP, uncompress it, and write it back to disk. Network configuration is fetched via DHCP. As the hard disk is processed as an image, any filesystem and operating system can be deployed using g4u. Easy cloning of local disks as well as partitions is also supported.
libhardware is a very small static library used in many utilities that are part of the "Bad Penguin" distribution. It provides functions to access information about your system hardware, to detect the hardware, and to handle kernel modules automatically. It is able to enumerate all PCI devices, enumerate all EIDE disks and CDROMs, enumerate all SCSI disks and CDROMs, enumerate all EIDE/SCSI disk partitions, and check if a detected device is supported in the Linux kernel using a custom PCI database. It can also handle USB devices. The included shell scripts 'probedisk' and 'probepart' detect disks, CDROMs, and partitions. The included 'scanmodule' utility allows you to detect devices and load their kernel modules automatically.
libgringo is a library to writes applications that run both in console (using ncurses) and under X-Window (using gtk). libgringo detects if you are running from the console or under X-Window, and selects the right library to use without recompiling your code. gringosh and gringodlg are two parsers that use libgringo to provide similar functionality to the cdialog utility. It was written to make some configuration scripts work both in console and under X Windows without any modification. gringosh and gringodlg also provide features more powerful than cdialog such as the ability to have more than two buttons per form and more than two windows on the screen.
