mod_auth_useragent2 is an Apache module that can be used to limit access to documents by means of the User-Agent. As an authentication method, this is really unsafe because it is easy to change the User-Agent in most browsers, but it could be used to prevent stupid bots and spiders from accessing your Web sites.
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.
ntpdate is a simple and small replacement for the homonymous and obsolete tool from the NTP Project's (www.ntp.org) reference implementation. ntpdate sets the local date and time by polling the Network Time Protocol (NTP) server(s) given as the server argument to determine the correct time. It must be run as root on the local host. It is not meant for real time synchronization.
rpm2python is a Web-based tool similar to rpm2html that clearly displays directories containing RPMs along with detailed RPM information such as dependencies and changelogs. It dynamically creates its RPM directory index and all RPM information is read on the fly to avoid dead links.
x509watch is a simple command line application that can be used to list soon expiring or already expired X.509 certificates, such as SSL certificates. All certificates are searched by default in the standard PKI directory, but any other directory can be specified as a parameter. Only Base64 encoded DER and PEM X.509 certificates are supported.
