20 | <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>. Create the file by running the |
---|
26 | following:</para> |
---|
27 | |
---|
28 | <screen><userinput>cat > /etc/resolv.conf << "EOF" |
---|
29 | <literal># Begin /etc/resolv.conf |

36 | EOF</userinput></screen> |
---|
37 | |
---|
38 | <para>Replace <replaceable>[IP address of the nameserver]</replaceable> |
---|
39 | with the IP address of the DNS most appropriate for the setup. There will |
---|
40 | often be more than one entry (requirements demand secondary servers for |
---|
41 | fallback capability). If you only need or want one DNS server, remove the |
---|
42 | second <emphasis>nameserver</emphasis> line from the file. The IP address |
---|
43 | may also be a router on the local network.</para> |
