| 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 |
---|
[1b896d0] | 25 | <filename>/etc/resolv.conf</filename>. If at least one of your network |
---|
[82c4aa0] | 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> |
---|
[5412eda] | 31 | |
---|
| 32 | <screen><userinput>cat > /etc/resolv.conf << "EOF" |
---|
| 33 | <literal># Begin /etc/resolv.conf |

| 36 | nameserver <replaceable>[IP address of your primary nameserver]</replaceable> |
---|

[05d3e34] | 42 | <para>The <replaceable>domain</replaceable> statement can be omitted or |
---|
| 43 | replaced with a <replaceable>search</replaceable> statement. See the man |
---|
| 44 | page for resolv.conf for more details.</para> |
---|
| 45 | |
---|
[5412eda] | 46 | <para>Replace <replaceable>[IP address of the nameserver]</replaceable> |
---|
| 47 | with the IP address of the DNS most appropriate for the setup. There will |
---|
| 48 | often be more than one entry (requirements demand secondary servers for |
---|
| 49 | fallback capability). If you only need or want one DNS server, remove the |
---|
| 50 | second <emphasis>nameserver</emphasis> line from the file. The IP address |
---|
| 51 | may also be a router on the local network.</para> |
