adsuck is a small DNS server that spoofs blacklisted addresses and forwards all other queries. The idea is to be able to prevent connections to undesirable sites such as ad servers, crawlers, etc. It can be used locally, for the road warrior, or on the network perimeter in order to protect local machines from malicious sites.
The epitome suite consists of several discrete pieces that provide storage deduplication services. Deduplication is defined as the elimination of redundant data. The idea behind epitome is to provide a WORM-based archive/backup mechanism that is lossless and offers permanent storage with inherent data protection properties. Additionally, it provides several metadata formats and back-ends to meet several usage models. It provides a number of services to enable three major archiving technologies: CAS, SIS, and DEDUP.
iogen is an I/O generator. It forks child processes that each run a mix of reads and writes. The idea is to generate heavily fragmented files to make the hardware suffer as much as possible. This tool has been used to test filesystems, drivers, firmware, and hardware devices. It is by no means meant as a performance measuring tool since it tries to recreate the worst case scenario I/O.
The OpenBSD project produces a free, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts place emphasis on portability, standardization, correctness, security, and cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSDI, SunOS, and HPUX.
scrotwm is a minimalistic window manager that tries to stay out of the way so that valuable screen real estate can be used for much more important stuff. It has sane defaults and does not require one to learn a language to do any configuration. It was written by hackers for hackers and it strives to be small, compact and fast.
There are several linux ports out there. I have seen Ubuntu, SLES, Arch, Debian and some others.
