ibistools is a small set of command-line tools that aid a PCB designer working with IBIS models. It currently consists of a full IBIS v4.1 parser and an IBIS to SPICE translator. IBIS (I/O Buffer Information Specification) is a standard, human-readable, machine-readable format for publishing IC specifications.
Signsrch is a tool that searches for signatures inside raw files and executables. It can recognize a large number of compression, multimedia, and encryption algorithms and many other things like known strings and portions of anti-debugging code. Definitions can be manually added, since they are based on an ease-to-modify text signature file that is read at runtime. It also supports the scanning of processes, conversion of executable memory offsets, 8, 16, 32 and 64 bits, float and double, plus automatic CRC table creation and C style strings.
Gammu (formerly known as MyGnokii2) is a cellular manager for various mobile phones/modems. It supports a wide variety of Nokia, Symbian, and AT devices (Siemens, Alcatel, Falcom, WaveCom, IPAQ, Samsung, SE, and others) over cables, infrared, or BlueTooth. It contains libraries with functions for ringtones, phonebook, SMS, logos, WAP, date/time, alarm, calls, and more (used by external applications like Wammu). It also includes a command line utility that can make many things (including backups) and an SMS gateway with full MySQL and PostgreSQL support from the PHP interface.
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.
smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.
gnokii is a multisystem tool suite for mobile phones. It provides a library to communicate with a phone hiding the communication protocol. The library handles SMS, phonebook, calendar, phone calls, and other mobile phone capabilities. It supports Nokia-FBUS mobiles, AT-capable phones (most of the mobiles), as well as Symbian-based phones.
