Linux From Scratch - Version 7.5-systemd

Chapter 6. Installing Basic System Software

6.41. Inetutils-1.9.2

The Inetutils package contains programs for basic networking.

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

6.41.1. Installation of Inetutils

Create a definition to allow the ifconfig program to build properly. 

echo '#define PATH_PROCNET_DEV "/proc/net/dev"' >> ifconfig/system/linux.h

Prepare Inetutils for compilation: 

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

The meaning of the configure options:

--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This option disables the building of the Inetutils whois client, which is out of date.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. 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
mv -v /usr/bin/ifconfig /sbin
