	What is TCP Wrapper? - a definition from Whatis.com
		- TCP Wrapper is a public domain computer program that provides firewall services for Unix servers.

		TCP Wrapper is a host-based network ACL system, used to filter network access to Internet protocol services run on (Unix-like) operating systems such as Linux or BSD.
		It allows host or subnetwork IP addresses, names and/or ident query replies, to be used as tokens on which to filter for access control purposes.
		While originally written to protect TCP and UDP accepting services, examples of usage to filter on certain ICMP packets (such as 'pingd' – the userspace ping request responder) exist too.

	CERT Advisory CA-1999-01 Trojan horse version of TCP Wrappers
		TCP Wrappers is a tool commonly used on Unix systems to monitor and filter connections to network services.
		We encourage sites who downloaded a copy of the TCP Wrapper after Thursday, January 21, 1999 at 06:16:00 GMT to verify the authenticity of their TCP Wrapper distribution, regardless of where it was obtained.
		As a workaround, until you are able to verify your copies of TCP Wrappers, you can block inbound connections with a source port of 421 at your network perimeter.

	open.itworld.com - Unix Tip: Introducing TCP Wrappers
		If you have never secured a Unix server with TCP Wrappers, you might be very surprised at how easily this can be done, especially on systems such as newer Linux servers on which the wrapper service is built in.
		The basic intent behind TCP Wrappers is to provide a security layer for services that don't have their own.
		When TCP Wrappers is used, the wrapper service receives the requests and determines whether or not to pass the request on to the intended service.

		TCP Spy.NET is a small application used to trace TCP packets between a client and a server.
		TCP Spy captures and displays all socket calls that an application makes and the data that is sent and received on the application's sockets.
		TCP Spy can be used by a developer to debug socket communication problems with an application or by anyone who is curious about what socket calls an application is making, including what it is communicating with and the data it is passing.

		Wenn es einem Client-Host erlaubt ist zu verbinden, gibt TCP Wrapper die Kontrolle über die Verbindung zum angeforderten Dienst und wird nicht mehr in die Kommunikation zwischen Client-Host und Server eingreifen.
		Zusätzlich zu Zugriffskontrolle und Logging, können TCP Wrapper Befehle aktivieren, um mit dem Client zu interagieren, bevor er die Kontrolle der Verbindung zum angeforderten Netzwerk-Dienst übergibt oder diesen ablehnt.

	Catching up with Wietse Venema, creator of Postfix and TCP Wrapper
		Wietse Venema is best known for the software TCP Wrapper, which is still widely used today and is included with almost all unix systems.
		Wietse is also the author of the Postfix mail system and the co-author of the very cool suite of utilities called The Coroner's Toolkit or "TCT".
