Net-tools のインストール

The instructions below automate the configuration process by piping yes to the make command. If you wish to run the interactive configuration process (by changing the instruction to just make), but you are not sure how to answer all the questions, then just accept the defaults. This will be just fine in the majority of cases. What you're asked here is a bunch of questions about which network protocols you've enabled in your kernel. The default answers will enable the tools from this package to work with the most common protocols: TCP, PPP, and several others. You still need to actually enable these protocols in the kernel—what you do here is merely tell the package to include support for those protocols in its programs, but it's up to the kernel to make the protocols available.

注記

This package has several unneeded protocols and hardware device specific functions that are obsolete. To only build the minimum needed for your system, skip the yes command and answer each question interactively. The minimum needed options are 'UNIX protocol family' and 'INET (TCP/IP) protocol family'.

For this package, we use the DESTDIR method of installation in order to easily remove files from the build that overwrite those that we want to keep or are not appropriate for our system.

以下のコマンドを実行して Net-tools をビルドします。

export BINDIR='/usr/bin' SBINDIR='/usr/bin' &&
yes "" | make -j1                           &&
make DESTDIR=$PWD/install -j1 install       &&
rm    install/usr/bin/{nis,yp}domainname    &&
rm    install/usr/bin/{hostname,dnsdomainname,domainname,ifconfig} &&
rm -r install/usr/share/man/man1            &&
rm    install/usr/share/man/man8/ifconfig.8 &&
unset BINDIR SBINDIR

このパッケージにテストスイートはありません。

root ユーザーになって以下を実行します。

chown -R root:root install &&
cp -a install/* /

コマンド説明

export BINDIR='/usr/bin' SBINDIR='/usr/bin': Ensure the executables are installed in the correct location.

yes "" | make : Piping yes to make config skips the interactive configuration and accepts the defaults.

rm ...: Remove unneeded programs and man pages.

パッケージ構成

インストールプログラム: arp, ipmaddr, iptunnel, mii-tool, nameif, netstat, plipconfig, rarp, route, and slattach
インストールライブラリ: なし
インストールディレクトリ: なし

概略説明

arp

is used to manipulate the kernel's ARP cache, usually to add or delete an entry, or to dump the entire cache

ipmaddr

adds, deletes and shows an interface's multicast addresses

iptunnel

adds, changes, deletes and shows an interface's tunnels

mii-tool

checks or sets the status of a network interface's Media Independent Interface (MII) unit

nameif

names network interfaces based on MAC addresses

netstat

is used to report network connections, routing tables, and interface statistics

plipconfig

is used to fine tune the PLIP device parameters, to improve its performance

rarp

is used to manipulate the kernel's RARP table

route

is used to manipulate the IP routing table

slattach

attaches a network interface to a serial line. This allows you to use normal terminal lines for point-to-point links to others computers
