Sup is a program used for upgrading collections of files from other machines to your machine. You execute sup, the client program, which talks over the network using IP/TCP to a file server process. The file server process cooperates with sup to determine which files of the collection need to be upgraded on your machine.

Tableutil is a utility for converting, aggregating and performing operations on lists of IP-addresses. Its primary use is to convert files into a format pfctl(8) can read. It can read plain-text-files with ranges (123.123.123.123-234.234.234.234), CIDR-style networks (192.168.0.0/24) single addresses (242.242.242.242) or with hostnames (one.two.com). It can also read p2b files.

Virtual Distributed Ethernet is a user-mode virtual network (layer 2) infrastructure. It can be used for network simulations, joining multiple qemu instances together in a shared virtual network, or tunneling over the Internet. Physical hosts can be joined to the virtual network by means of the tap(4) driver.

throttled is a bandwidth shaping application for FreeBSD which allows you to cap your upstream bandwidth, prioritize ACK packets, and keep your download speeds high even when your server is sending out at full speed. It uses almost no cpu, and has a tiny footprint. Enjoy. For more information you can read the comments in throttled-startup

Whois is an intelligent pure Ruby WHOIS client and parser. It provides a flexible and programmable API to query WHOIS servers and look up IP/domain WHOIS information. It also offers command-line interface to run WHOIS queries from the console. It is a OS-independent library and does not require external C libraries or Gems.

Samba4 is an attempt to implement an Active Directory compatible Domain Controller. In short, you can join a WinNT, Win2000, WinXP or Win2003 member server to a Samba4 domain, and it will behave much as it does in AD, including Kerberos domain logins where applicable.

The u6rd is a user-space 6rd (RFC 5569) implementation, which uses tun(4) and the raw socket interface. The u6rd daemon runs on the 6rd border router of a 6rd site that is isolated from the native IPv6 Internet. It does not provide the functionality of 6rd "relay" routers.

UCARP allows a couple of hosts to share common virtual IP addresses in order to provide automatic failover. It is a portable userland implementation of the secure and patent-free Common Address Redundancy Protocol (CARP, OpenBSD's alternative to the VRRP).
