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}
Non-Multilib
Configure and compile the package:
gzip -dc ../tcp-wrappers_7.6-ipv6.1-3.diff.gz | patch -Np1 && sed -i "s,^extern char \*malloc();,/* & */," scaffold.c && make REAL_DAEMON_DIR=/usr/sbin STYLE=-DPROCESS_OPTIONS linux
Install the package:
make install

| Installed Programs: | tcpd, tcpdchk, tcpdmatch, try-from, and safe_finger |
|---|---|
| Installed Libraries: | libwrap.{so,a} |
| Installed Directories: | None |
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”. |
