<para>If a network card is to be configured, you have to decide on the
|
|
IP-address, FQDN and possible aliases for use in the /etc/hosts file. The
|
|
syntax is:</para>
|
|
|
|
<screen><IP address> myhost.example.org aliases</screen>
|
|
|
|
<para>You should make sure that the IP-address is in the private network
|
|
IP-address range. Valid ranges are:</para>
|
|
|
|
<screen> Class Networks
|
|
A 10.0.0.0
|
|
B 172.16.0.0 through 172.31.0.0
|
|
C 192.168.0.0 through 192.168.255.0</screen>
|
|
|
|
<para>A valid IP address could be 192.168.1.1. A valid FQDN for this IP could
|
|
be www.linuxfromscratch.org.</para>
|
|
|
|
<para>If you aren't going to use a network card, you still need to
|
|
come up with a FQDN. This is necessary for certain programs to operate
|
|
correctly.</para>
|
|
|
|
<para>If a network card is not going to be configured, create the
|
|
<filename>/etc/hosts</filename> file by running:</para>
|
|
|
|
<screen><userinput>cat > /etc/hosts << "EOF"</userinput>
|
|
# Begin /etc/hosts (no network card version)
|
|
|
|
127.0.0.1 <value of HOSTNAME>.example.org <value of HOSTNAME> localhost
|
|
|
|
# End /etc/hosts (no network card version)
|
|
<userinput>EOF</userinput></screen>
|
|
|
|
<para>If a network card is to be configured, create the
|
|
<filename>/etc/hosts</filename> file by running:</para>
|
|
|
|
<screen><userinput>cat > /etc/hosts << "EOF"</userinput>
|
|
# Begin /etc/hosts (network card version)
|
|
|
|
127.0.0.1 localhost
|
|
192.168.1.1 <value of HOSTNAME>.example.org <value of HOSTNAME>
|
|
|
|
# End /etc/hosts (network card version)
|
|
<userinput>EOF</userinput></screen>
|
|
|
|
<para>Of course, the 192.168.1.1 and <value of HOSTNAME>.example.org
|
|
have to be changed to your liking (or requirements if assigned an IP-address
|
|
by a network/system administrator and this machine is planned to be connected
|
|
to an existing network).</para>
