trapdoor2 allows remote users to execute local commands by sending 'magic cookies'. this can e.g. be used to alter local firewalling rules so people can connect to local services after sending the magic cookie. trapdoor2 is implemented as a high-secure HTTPS server and includes support for the Wireless Application Protocol (WAP).
trash-cli is a command line interface to the FreeDesktop.org trashcan. It implements the FreeDesktop.org trash specification. For each trashed file, it will remember the name, original path, date of deletion, and permissions. It interoperates with KDE and GNOME Trash, and is CLI compatible with the rm command.
travtrack is a tool to help a Traveller(tm) referee keep track of essential data for a game. Already implemented are galaxies, sectors, subsectors, systems, stars, planets, belt and moons. Yet to be implemented are trade routes, ships, characters, and all the rest. These will take some time, but should not be too complex. It currently uses the GURPS Traveller:First In rules for system generation, but a subproject is under way to add Classic Traveller generation and output. travlib is a collection of C routines that should make writing a Traveller application easier. A guile interface to the data representation functions is provided.
Treeps is program for Unix/Linux that is designed to make monitoring and interacting with the running programs on your system easy and intuitive. A "real time" tree view shows the relationships between the processes and is color-coded to provide easy interpretation of various values. The process tree displays any combination of users/groups and can be used to drill down into process details and then extract key fields for continuous monitoring. A number of actions can be performed on processes, such as signal, renice, trace, view man page, etc.
Treewatch watches a directory for a specified type of file to change. When one of the files changes, treewatch runs a program of the user's choice. By default, treewatch will watch the current directory and run "make" when changes are detected in files ending in .cpp, .c, or .h. The user can specify any number of directories to watch, any number of file types to watch for, and any command line to run.
trend is a general-purpose, efficient trend graph for "live" data. Data is read in ASCII format from a file or continuously from a FIFO, and is played in real-time into a multi-pass trend (much like a CRT oscilloscope or a strip chart). trend can be used as a rapid analysis tool for progressive or time-based data series together with trivial scripting.
tresor is an application for performing full backup and fast restores with bytepositioning tape drives. This option is available on some Tandberg and Wangtek streamers and some SCSI-2 tape drives. It features flexible configuration, a database for multiple volumes, fast restores (due to direct seeking), a graphical user interface, tape operations based on dd, afio, and mt, and tape identification using its own header. Language support for German and English is included.
trickle is a lightweight, portable, per-application bandwidth shaper. It works in collaboration, has peak detection, and does smoothing. trickle works entirely in userland and does not require root to run. It has been developed on OpenBSD and is known to run on Linux, FreeBSD, and Solaris.
