Linux From Scratch - Version 7.10-rc1-systemd

Chapter 6. Installing Basic System Software

6.39. Inetutils-1.9.4

The Inetutils package contains programs for basic networking.

Approximate build time: 0.4 SBU
Required disk space: 28 MB

6.39.1. Installation of Inetutils

Prepare Inetutils for compilation: 

./configure --prefix=/usr        \
            --localstatedir=/var \
            --disable-logger     \
            --disable-whois      \
            --disable-rcp        \
            --disable-rexec      \
            --disable-rlogin     \
            --disable-rsh        \
            --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 installs a more recent version.

--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This option disables the building of the Inetutils whois client, which is out of date.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-r*

These parameters disable building obsolete programs that should not be used due to security issues. The functions provided by these programs can be provided by the openssh package 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

One test, libls.sh, is known to fail due to hard coding of some support program paths. All tests pass if the tests are rerun at the end of Chapter 6.

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
