    <para>If the system is going to be connected to the Internet, it will
21
    need some means of Domain Name Service (DNS) name resolution to
22
    resolve Internet domain names to IP addresses, and vice versa. This is
23
    best achieved by placing the IP address of the DNS server, available
24
    from the ISP or network administrator, into
25
    <filename>/etc/resolv.conf</filename>. If at least one of your network
26
    interfaces is going to be configured by DHCP then you may not need to
27
    create this file. By default DHCPCD will overwrite this file when it gets
28
    a new lease from the DHCP server. If you wish to manually configure your
29
    network interfaces or manually set your DNS using DHCP then create the
30
    file by running the following:</para>

<screen><userinput>cat &gt; ${CLFS}/etc/resolv.conf &lt;&lt; "EOF"

# End /etc/resolv.conf</literal>
40
EOF</userinput></screen>
41
 
42
    <para>Replace <replaceable>[IP address of the nameserver]</replaceable>
43
    with the IP address of the DNS most appropriate for the setup. There will
44
    often be more than one entry (requirements demand secondary servers for
45
    fallback capability). If you only need or want one DNS server, remove the
46
    second <emphasis>nameserver</emphasis> line from the file. The IP address
47
    may also be a router on the local network.</para>
