countertrace is a userland iptables QUEUE target handler for Linux 2.4 kernels running Netfilter.

The imaginary hops that countertrace projects also have the ability to introduce accumulative, imaginary latency.
rh-errata is a tool for maintaining the integrity of a Red Hat Linux system. It builds a respository of RPM files from a designated mirror of the Red Hat updates site. It only downloads RPM files that have not already been downloaded. Optionally, it can produce a report that shows which RPM files in your respository need to be updated and which ones have already been installed.
