Introduction to TCP Wrappers

TCP Wrapper is a host-based network ACL system, used to filter network access to Internet protocol services run on Unix-like operating systems.

Project Homepage: ftp://ftp.porcupine.org/pub/security/index.html. Updated to support ipv6 through debian port.

Configuration Information

Note

TCP Wrapper does use DESTDIR. However, it fails to create the necessary directories for it and so make install fails when using DESTDIR. You need to create the necessary directories prior to installation.
install -dv <DESTDIR>/lib (or lib{32} or lib{64})
install -dv <DESTDIR>/usr/include
install -dv <DESTDIR>/usr/lib (or lib{32} or lib{64})
install -dv <DESTDIR>/usr/sbin
install -dv <DESTDIR>/usr/share/man/man{3,5,8}

Short Descriptions

tcpd is the main access control daemon for all Internet services, which inetd or xinetd will run instead of running the requested service daemon.
tcpdchk is a tool to examine a tcpd wrapper configuration and report problems with it.
tcpdmatch is used to predict how the TCP wrapper would handle a specific request for a service.
try-from can be called via a remote shell command to find out if the host name and address are properly recognized.
safe_finger is a wrapper for the finger utility, to provide automatic reverse name lookups.
libwrap.{so,a} contains the API functions required by the TCP Wrapper programs as well as other programs to become “TCP Wrapper-aware”.
