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.
Tcsh is an enhanced but completely compatible version of the Berkeley UNIX C shell. It is a command language interpreter usable both as an interactive login shell and a shell script command processor. It includes a command line editor, programmable word completion, command and file name completion, listing, spelling correction, a history mechanism, job control, and a bunch of small additions to the csh shell itself.
Telephone Control Daemon allows a user to dial a system and perform some predefined commands. It uses a voice modem (tested with Rockwell) to provide a DTMF-based interface to the user. It is useful for systems that only have a temporary Internet connection but may need to be connected at the demand of some remote user.
Wapsh allows users to login to a Unix workstation using a WAP-capable mobile phone. Features include shortcuts (to save phone typing), input of control and other special characters, command history, and searching and scrolling through long shell output. Wapsh automatically adapts to the main WAP browsers (UP and Nokia), and uses configuration files to further tailor the system for specific phones. A corresponding HTML (Web) interface is also included.
