TCP Banner allows you to place a banner message on a given port (and IP). This is useful if you have moved an application to another port or IP address. The inbound connection gets presented with the message you define and then gets disconnected. This makes use of the socklib library.
mydp is a program for processing mysqldump files in the manner of ‘awk’. It reads mysqldump SQL statements from standard input and executes Lua callback functions as table definitions and insert statements are encountered. The Lua callback functions are specified in a file passed to mydp via the command line. The callbacks are typically used to filter and process only a small subset of the MySQL dump data and/or save it for further processing. mydp is written in Lex and Lua.
libsysconfcpus is an $LD_PRELOAD library that intercepts calls to sysconf() and adjusts the responses for _SC_NPROCESSORS_CONF and _SC_NPROCESSORS_ONLN, which are used to determine the number of processors available (either configured or online) at runtime in a system. Unfortunately, some closed-source software assumes that all of these processors may be used for computation, which is an assumption that is frequently not true on multiuser and HPC systems. libsysconfcpus provides a simple, non-intrusive way of adjusting the behavior of such software (when it is dynamically linked).
xlibtrace displays the interaction between X11 client programs and the X11 client shared library (libX11.so) by showing the Xlib calls that are made. Output is shown in a style similar to strace(1). It works by using the $LD_PRELOAD dynamic linker option to insert itself between the target X11 client program and libX11.so. This allows it to "intercept" all calls to X functions, whereupon it has the opportunity to print the name of the function being called, along with any arguments and return value. This can be particularly useful when analyzing the behavior of closed-source X11 programs.
depfinder finds the dependencies of Slackware packages. The dependency list can be output to stdout, to a .dep text file without version information, or to a slack-required file with version information. depfinder is very fast; its speed is mainly due to the C++ code that is used in depfinder to find in which package each individual library is included. It also has support for running multiple jobs, which makes it a lot faster when used with multiple CPUs/cores. depfinder supports detecting dependencies of binary files compiled with languages such as C or C++ and it can also detect Python dependencies.
Artha is a handy thesaurus based on WordNet with distinct features like global hot key look up, passive desktop notification, regular expression based search, etc. Artha may be used as a free open-source replacement/clone to the proprietary WordWeb Pro thesaurus (which is also based on WordNet) on Unix-like and Windows operating systems.
LEPL is a recursive descent parser library written in Python. It is based on parser combinator libraries popular in functional programming, but also exploits Python language features. Operators provide a friendly syntax, and the consistent use of generators supports full backtracking and resource management. Backtracking implies that a wide variety of grammars are supported; appropriate memoisation ensures that even left-recursive grammars terminate.
Webtunnel is a network utility that encapsulates arbitrary data in HTTP and transmits it through a Web server. In that regard, it is similar to httptunnel. However, its server component runs in the context of a Web server as a CGI application (with optional FastCGI support), so it does not need its own port. It supports most things that the Web server supports, such as authentication, HTTP 1.1, HTTPS, and client certificates. It uses simple requests and responses so it works seamlessly through forward and reverse proxies.
