Monkey HTTP Daemon is a very fast and lightweight Web server for Linux. It uses a hybrid networking model based on asynchronous calls (event-driven) and fixed threads, which makes it scalable and capable of attending thousands of clients per second. It provides a powerful API for C and is ideal for embedded devices, thanks to its small core and plugin architecture.
Polypy is a small program to analyze rings in structures read from xyz files. This can be used, for example, to identify defects in crystal structures. The program was initially developed to analyze graphitic carbon structures, but can be used for any other structure. It includes: ring search using Franzblau statistics [Phys. Rev. B 44, 4925]; output structures marked by ring size, which can used for visualization in a program such as VMD; and extensive output with which atoms are in which ring and the neighbors of each atom.
Libfastcounters is a C library to maintain counters. It makes it convenient for a server program to count many kinds of events. Incrementing is fast, on the order of nanoseconds. Incrementing is atomic. Counters are shared across processes. Counters are persistent. You can address counters by number or by name. Libfastcounters includes a command line tool to create, modify, and read the persistent counters file.
MySQLi Query is a class that executes queries from parameter lists using MySQLi. It extends the MySQLi class with functions that can compose and execute SELECT, INSERT, UPDATE, DELETE, REPLACE, and HANDLER queries with parameter values that define tables, fields, field values, conditions, etc. The class destructor function disconnects from the MySQL server.
fake sshd is a fake SSH daemon that logs password attack attempts. It differs from other tools by being built with libssh instead of being a modified version of OpenSSH. It provides no way to login to a shell and can be used to tarpit or delay attackers, and "steal" an attacker's dictionary.
Bastille Unix (formerly Bastille Linux) aims to be the most comprehensive, flexible, and educational Security Hardening Program for Red Hat (Fedora Core, Enterprise Linux, and original Red Hat), SuSE, Gentoo, Mandrake, and Debian Linux, as well as HP-UX and Mac OS X. Virtually every task it performs is optional, providing immense flexibility. It educates the installing admin regarding the topic at hand before asking any question. The interactive nature allows the program to be more thorough when securing, while the educational component produces an admin who is less likely to compromise the increased security.
