This tool removes blocks of 0x00 from files by replacing them with
phantomblocks. That way, a file uses less diskspace while its contents
hasn't changed at all!
BEWARE: after copying these files with tar, cp, cpio or any other tool,
the phantomblocks have been replaced with 0x00-blocks again!
EXAMPLE:
find / -type f -print | xargs -n 1 phantom -r -i
This would go trough the whole harddisk, scan all files and generate
0x00-blocks where necessary.
Utility to administer the rc.conf system configuration file.
rcadm features:
* listing current settings
* enabling/disabling services
* setting and getting arbitrary variables
rclean provides a command-line tool to order and clean content of
rc.conf, using option order from /etc/defaults/rc.conf and printing only
choices that were different by the default value in /etc/rc.conf.
Output is customizable from "only used values" to "full listing".
This is the last version that handles both the 8.x and 9.x install
media formats.
Qjail [ q = quick ] is a 4th generation wrapper for the basic chroot jail
system that includes security and performance enhancements. Plus a new level
of "user friendliness" enhancements dealing with deploying just a few jails or
large jail environments consisting of 100's of jails.
Qjail requires no knowledge of the jail command usage. It uses "nullfs" for
read-only system binaries, sharing one copy of them with all the jails.
Uses "mdconfig" to create sparse image jails. Sparse image jails provide a
method to limit the total disk space a jail can consume, while only occupying
the physical disk space of the sum size of the files in the image jail.
Ability to assign ip address with their network device name,
so aliases are auto created on jail start and auto removed on jail stop.
Ability to create "ZONE"s of identical qjail systems, each with their own
group of jails.
Ability to designate a portion of the jail name as a group prefix so the
command being executed will apply to only those jail names matching that prefix.
rdate(8) sets the clock of the local host to the time of another host.
OpenBSD's rdate is a much improved version of the original rdate(8)
by Christos Zoulas. This version not only supports RFC 868,
but also RFC 5905 (NTP, SNTP), which is now used by default.
Both IPv4 and IPv6 are supported.
This qjail version only supports the RELEASE-10.x series of releases.
Qjail [ q = quick ] is a 4th generation wrapper for the basic chroot jail
system that includes security and performance enhancements. Plus a new level
of "user friendliness" enhancements dealing with deploying just a few jails or
large scale jail environments consisting of 100's of jails.
Qjail uses the jail(8) jail.conf method. This provides the ability to enable
the following options on a per-jail basis. exec.fib, securelevel, allow.sysvipc,
devfs_rulesets, allow.raw_sockets, allow.quotas, allow.mount.nullfs,
allow.mount.tmpfs, allow.mount.zfs, vnet.interface, and vnet. The vnet option
gives a jail its own network stack using the experimental vimage kernel module.
The vnet option has only been tested on i386 and amd64 equipment.
Qjail requires no knowledge of the jail command usage. It uses "nullfs" for
read-only system executables, sharing one copy of them with all the jails.
Uses "mdconfig" to create sparse image jails. Sparse image jails provide a
method to limit the total disk space a jail can consume, while only occupying
the physical disk space of the sum size of the files in the image jail.
Ability to assign ip address with their network device name,
so aliases are auto created on jail start and auto removed on jail stop.
Ability to create "ZONE"s of identical qjail systems, each with their own
group of jails.
Ability to designate a portion of the jail name as a group prefix so the
command being executed will apply to only those jail names matching that prefix.
Qjail has been incorporated into the Finch open source project,
see http://dreamcat4.github.io/finch/ for details.
The phybs utility attempts to measure disk performance for various I/O
block sizes and alignments. It can be used to deduce the physical block
size of a hard disk drive or the stripe size of an array.
Cfengine is an automated suite of programs for configuring and
maintaining Unix-like computers. It has been used on computing arrays
of between 1 and 20,000 computers since 1993 by a wide range of
organizations. Cfengine is supported by active research and was the
first autonomic, hands-free management system for Unix-like operating
systems. Cfengine is an autonomic maintenance system not merely a
change management roll-out tool. Cfengine has a history of security
and adaptability.

Zeitgeist is a service which logs the users's activities and events
(files opened, websites visites, conversations hold with other people,
etc.) and makes relevant information available to other applications.
It is able to establish relationships between items based on
similarity and usage patterns.
libQZeitgeist is a wrapper library around the Zeitgeist D-Bus API for
Qt, and is brought to you by Collabora in cooperation with the
Zeitgeist team and KDE.
