Introduction to TCP Wrappers
The TCP Wrappers package provides daemon wrapper programs that report the name of the client requesting network services and the requested service.
Dependencies
Non-Multilib
Configure and compile the package:
patch -Np1 -i ../tcp_wrappers-7.6-shared_lib_plus_plus-1.patch && sed -i "s,^extern char \*malloc();,/* & */," scaffold.c && make REAL_DAEMON_DIR=/usr/sbin STYLE=-DPROCESS_OPTIONS linux
Install the package:
make install
Command Explanations
sed -i -e ... scaffold.c: This command removes an obsolete C declaration which causes the build to fail if using GCC >= 3.4.x.
Multilib
32Bit
Configure and compile the package:
patch -Np1 -i ../tcp_wrappers-7.6-shared_lib_plus_plus-1.patch &&
sed -i "s,^extern char \*malloc();,/* & */," scaffold.c &&
make CC="gcc ${BUILD32}" REAL_DAEMON_DIR=/usr/sbin STYLE=-DPROCESS_OPTIONS linux
Install the package:
make install
N32
Configure and compile the package:
patch -Np1 -i ../tcp_wrappers-7.6-shared_lib_plus_plus-1.patch &&
sed -i "s,^extern char \*malloc();,/* & */," scaffold.c &&
sed -i -e "s@/lib/@/lib32/@g" Makefile &&
make CC="gcc ${BUILDN32}" REAL_DAEMON_DIR=/usr/sbin STYLE=-DPROCESS_OPTIONS linux
Install the package:
make install
64Bit
Configure and compile the package:
patch -Np1 -i ../tcp_wrappers-7.6-shared_lib_plus_plus-1.patch &&
sed -i "s,^extern char \*malloc();,/* & */," scaffold.c &&
sed -i -e "s@/lib/@/lib64/@g" Makefile &&
make CC="gcc ${BUILD64}" REAL_DAEMON_DIR=/usr/sbin STYLE=-DPROCESS_OPTIONS linux
Install the package:
make install
Contents
| 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”. |
