dhcpcd.conf - Configure dhcpdΒΆ

This configures the DCHP daemon to statically assign IP addresses for eth0 and wlan0. See dhcpcd.conf(5) for details.

Allow users of this group to interact with dhcpcd via the control socket.

#controlgroup wheel

Inform the DHCP server of our hostname for DDNS.

hostname

Use the hardware address of the interface for the Client ID.

clientid

or Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per RFC4361. Some non-RFC compliant DHCP servers do not reply with this set. In this case, comment out duid and enable clientid above.

#duid

Persist interface configuration when dhcpcd exits.

persistent

Rapid commit support. Safe to enable by default because it requires the equivalent option set on the server to actually work.

option rapid_commit

A list of options to request from the DHCP server.

option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes

Respect the network MTU. This is applied to DHCP routes.

option interface_mtu

Most distributions have NTP support.

#option ntp_servers

A ServerID is required by RFC2131.

require dhcp_server_identifier

Generate SLAAC address using the Hardware Address of the interface

#slaac hwaddr

OR generate Stable Private IPv6 Addresses based from the DUID

slaac private

Example static IP configuration:

#interface eth0
#static ip_address=192.168.0.10/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
#static routers=192.168.0.1
#static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1

It is possible to fall back to a static IP if DHCP fails: define static profile

#profile static_eth0
#static ip_address=192.168.1.23/24
#static routers=192.168.1.1
#static domain_name_servers=192.168.1.1

fallback to static profile on eth0

#interface eth0
#fallback static_eth0

interface eth0
    static ip_address=192.168.2.1/24

interface wlan0
    static ip_address=192.168.3.1/24
    nohook wpa_supplicant
