Linux From Scratch - Version 7.3

Chapter 6. Installing Basic System Software

6.36. Inetutils-1.9.1

The Inetutils package contains programs for basic networking.

Approximate build time: 0.4 SBU
Required disk space: 27 MB

6.36.1. Installation of Inetutils

Fix an incompatibility between this package and Glibc-2.17 

sed -i -e '/gets is a/d' lib/stdio.in.h

Prepare Inetutils for compilation: 

./configure --prefix=/usr  \
    --libexecdir=/usr/sbin \
    --localstatedir=/var   \
    --disable-ifconfig     \
    --disable-logger       \
    --disable-syslogd      \
    --disable-whois        \
    --disable-servers

The meaning of the configure options:

--disable-ifconfig

This option prevents Inetutils from installing the ifconfig program, which can be used to configure network interfaces. LFS uses ip from IPRoute2 to perform this task.

--disable-logger

This option prevents Inetutils from installing the logger program, which is used by scripts to pass messages to the System Log Daemon. Do not install it because Util-linux installed a version earlier.

--disable-syslogd

This option prevents Inetutils from installing the System Log Daemon, which is installed with the Sysklogd package.

--disable-whois

This option disables the building of the Inetutils whois client, which is out of date. Instructions for a better whois client are in the BLFS book.

--disable-servers

This disables the installation of the various network servers included as part of the Inetutils package. These servers are deemed not appropriate in a basic LFS system. Some are insecure by nature and are only considered safe on trusted networks. More information can be found at http://www.linuxfromscratch.org/blfs/view/svn/basicnet/inetutils.html. Note that better replacements are available for many of these servers.

Compile the package: 

make

To test the results, issue: 

make check

Install the package: 

make install

Move some programs so they are available if /usr is not accessible: 

mv -v /usr/bin/{hostname,ping,ping6,traceroute} /bin
