|
||
<para>By default, NixOS uses DHCP (specifically,
|
||
<command>dhcpcd</command>) to automatically configure network
|
||
interfaces. However, you can configure an interface manually as
|
||
follows:
|
||
|
||
<programlisting>
|
||
networking.interfaces.eth0.ip4 = [ { address = "192.168.1.2"; prefixLength = 24; } ];
|
||
</programlisting>
|
||
|
||
Typically you’ll also want to set a default gateway and set of name
|
||
servers:
|
||
|
||
<programlisting>
|
||
networking.defaultGateway = "192.168.1.1";
|
||
networking.nameservers = [ "8.8.8.8" ];
|
||
</programlisting>
|
||
|
||
</para>
|
||
|
||
<note><para>Statically configured interfaces are set up by the systemd
|
||
service
|
||
<replaceable>interface-name</replaceable><literal>-cfg.service</literal>.
|
||
The default gateway and name server configuration is performed by
|
||
<literal>network-setup.service</literal>.</para></note>
|
||
|
||
<para>The host name is set using <option>networking.hostName</option>:
|
||
|
||
<programlisting>
|
||
networking.hostName = "cartman";
|
||
</programlisting>
|
||
|
||
The default host name is <literal>nixos</literal>. Set it to the
|
||
empty string (<literal>""</literal>) to allow the DHCP server to
|
||
provide the host name.</para>
