Statsnet is a small set of scripts that will generate graphical statistics for a specific device. The statistics contain among other things, transmitted/received packets as well as bytes. In addition, it shows amount of currently tracked connections in the conntrack engine of netfilter.
Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting several different steganographic methods to embed hidden information in JPEG images. Currently, the detectable schemes are jsteg, jphide, invisible secrets, outguess 01.3b, F5, appendX, and camouflage. Using linear discriminant analysis, it also supports detection of new stego systems. Stegbreak is used to launch dictionary attacks against JSteg-Shell, JPHide, and OutGuess 0.13b.
stegfs is a Fuse based file system which provides absolute security. Using encryption to secure files, and the art of steganography to hide them, stegfs aims to ensure that the existence of such files isn't guaranteed. Implemented as a Fuse based file system and using the mhash and mcrypt libraries to provide the cryptographic hash and symmetric block cipher functions, stegfs is at the cutting edge of secure file system technology.
stegnate is a program to hide data in BMPs or WAVs. stegnate-gtk is the GTK version. Under GTK versions later than 1.2, it may not compile, but it works from a command prompt and doesnt need GTK at all. At the moment, this software can only hide data in 8 or 16 bit BMPs and 8 or 16 bit WAVs.
stickystatus displays the sticky and mouse key status in a popup image. The image disappears when no sticky or mouse keys are pressed. It is fully configurable: custom images, popup location, characters used for each key, position of characters, font used, and color of characters. These are all set from the command line (no dot file).
The stmpclean utility removes old files (and old empty directories) from the specified directory. It is meant to be used to clean directories such as "/tmp" where old files tend to accumulate. stmpclean never removes files or directories owned by root, which is a feature, not a bug. Great care is taken while descending into the directory, and the operation is secure. Anything that's not a directory, regular file, or symbolic link is also left alone (because programs like screen(1) create sockets and FIFOs under /tmp and expect them to be long-lived). Unlike other programs that do the same task, stmpclean never forks and consumes limited amount of memory. If stmpclean determines a race condition it will log the situation and exit with a failure.
