x11vnc allows one to remotely view and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. It is designed to be compatible with all Unix variants and Mac OS X, and depends on a small set of standard libraries. It supports SSL/TLS and VeNCrypt encryption, Unix password logins, single port access, Zeroconf, file transfer, and UltraVNC extensions. It is part of the LibVNCServer project.
Viewglob is a filesystem visualization add-on for Bash and Zsh. It tracks the command line and environment of any number of interactive shells (local and remote). A graphical display follows the currently active terminal, listing the contents of directories relevant to its shell and highlighting file selections and potential name completions dynamically.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
Closebracket lets you define multiple shell actions in a single command to speed up the typing of the most repetitive shell commands. It includes ']' and '][' commands, which are located near the "Enter" key and are easy to type quickly. They invoke primary and secondary actions respectively.
vlock is a program to lock one or more sessions on the Linux console. This is especially useful for Linux machines which have multiple users with access to the console. One user may lock his or her session(s) while still allowing other users to use the system on other virtual consoles. If desired, the entire console may be locked and virtual console switching disabled.
xlax is an X11 input multiplexer: it sends your keyboard input from the xlax window to a group of windows simultaneously. The tool is designed for system administrators who typically have to do the same thing on several machines (or in several different directories). Windows can be added or deleted interactively, or temporarily disconnected and reconnected. xlax allows you to assign a custom string to each window (e.g. a hostname) that can be sent with a button click. An included script handles starting up and arranging windows, and allows you to set up commonly used window groupings in a config file.
Bashrun provides a powerful application launcher by running a specialized bash session in a small terminal window, conveniently providing bash features like tab completion and history. Additional features include user-configurable rules for automatically launching certain commands in a new terminal window, looking up manual and info pages, performing dict and Google queries, defining bookmarks for Web pages, or piping command output to the clipboard. Users can add more functionality by defining arbitrary rules for rewriting command lines based on regular expression matches and file test operators. This makes new features like file associations or Web shortcuts trivial to implement.
