mod_log_post is an Apache module that can be used for logging all HTTP POST messages. The module is based on mod_security, but it never returns any error messages to the visitors of your Web sites. Logging of POST data can be very useful for debugging purposes or analyses. As the module is loaded and run after the SSL decryption, it even can log POST data transmitted before via SSL to the Apache Web server.
Secrond is a light-weight cron implementation that allows running of user-specified programs at periodic scheduled times, handling tasks in intervals of seconds rather than minutes, as well as hours and days. While it is possible to achieve similar behavior by using a traditional cron daemon and adding calls to sleep() to the programs executed, it is impractical.
The fstrcmp library provides an fstrcmp function that returns a number between 0.0 (nothing alike) and 1.0 (identical); this can be used to suggest likely alternatives in error messages. Fuzzy comparisons for byte arrays, wide character strings, and multi-byte character strings are also available. In addition, there are integer alternatives for systems with slow floating point emulation.
