Dhcpcd

`networking.dhcpcd.IPv6rs`

Force enable or disable solicitation and receipt of IPv6 Router Advertisements. This is required, for example, when using a static unique local IPv6 address (ULA) and global IPv6 address auto-configuration with SLAAC.

Type: null or boolean

Default

null

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/networking/dhcpcd.nix

`networking.dhcpcd.allowInterfaces`

Enable the DHCP client for any interface whose name matches any of the shell glob patterns in this list. Any interface not explicitly matched by this pattern will be denied. This pattern only applies when non-null.

Type: null or (list of string)

Default

null

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/networking/dhcpcd.nix

`networking.dhcpcd.denyInterfaces`

Disable the DHCP client for any interface whose name matches any of the shell glob patterns in this list. The purpose of this option is to blacklist virtual interfaces such as those created by Xen, libvirt, LXC, etc.

Type: list of string

Default

[ ]

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/networking/dhcpcd.nix

`networking.dhcpcd.enable`

Whether to enable dhcpcd for device configuration. This is mainly to explicitly disable dhcpcd (for example when using networkd).

Type: boolean

Default

true

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/networking/dhcpcd.nix

`networking.dhcpcd.extraConfig`

Literal string to append to the config file generated for dhcpcd.

Type: strings concatenated with "\n"

Default

""

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/networking/dhcpcd.nix

`networking.dhcpcd.persistent`

Whenever to leave interfaces configured on dhcpcd daemon shutdown. Set to true if you have your root or store mounted over the network or this machine accepts SSH connections through DHCP interfaces and clients should be notified when it shuts down.

Type: boolean

Default

false

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/networking/dhcpcd.nix

`networking.dhcpcd.runHook`

Shell code that will be run after all other hooks. See man dhcpcd-run-hooks for details on what is possible.

Type: strings concatenated with "\n"

Default

""

Example

"if [[ $reason =~ BOUND ]]; then echo $interface: Routers are $new_routers - were $old_routers; fi"

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/networking/dhcpcd.nix

`networking.dhcpcd.wait`

This option specifies when the dhcpcd service will fork to background. If set to "background", dhcpcd will fork to background immediately. If set to "ipv4" or "ipv6", dhcpcd will wait for the corresponding IP address to be assigned. If set to "any", dhcpcd will wait for any type (IPv4 or IPv6) to be assigned. If set to "both", dhcpcd will wait for both an IPv4 and an IPv6 address before forking. The option "if-carrier-up" is equivalent to "any" if either ethernet is plugged nor WiFi is powered, and to "background" otherwise.

Type: one of "background", "any", "ipv4", "ipv6", "both", "if-carrier-up"

Default

"any"
