null

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

`services.avahi.allowPointToPoint`

Whether to use POINTTOPOINT interfaces. Might make mDNS unreliable due to usually large latencies with such links and opens a potential security hole by allowing mDNS access from Internet connections.

Type: boolean

Default

false

`services.avahi.cacheEntriesMax`

Number of resource records to be cached per interface. Use 0 to disable caching. Avahi daemon defaults to 4096 if not set.

Type: null or signed integer

Default

null

"local"

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

`services.avahi.enable`

Whether to run the Avahi daemon, which allows Avahi clients to use Avahi's service discovery facilities and also allows the local machine to advertise its presence and services (through the mDNS responder implemented by avahi-daemon).

Type: boolean

Default

false

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

`services.avahi.extraConfig`

Extra config to append to avahi-daemon.conf.

Type: strings concatenated with "\n"

Default

""

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

`services.avahi.extraServiceFiles`

Specify custom service definitions which are placed in the avahi service directory. See the {manpage}avahi.service(5) manpage for detailed information.

Type: attribute set of (string or path)

Default

{ }

Example

{ssh = "${pkgs.avahi}/etc/avahi/services/ssh.service";smb = '' <?xml version="1.0" standalone='no'?> <!DOCTYPE service-group SYSTEM "avahi-service.dtd"> <service-group> <name replace-wildcards="yes">%h</name> <service> <type>_smb._tcp</type> <port>445</port> </service> </service-group> '';}

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

`services.avahi.hostName`

Host name advertised on the LAN. If not set, avahi will use the value of {option}config.networking.hostName.

Type: string

Default

config.networking.hostName

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

`services.avahi.ipv4`

Whether to use IPv4. Type: boolean

Default

true

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

`services.avahi.ipv6`

Whether to use IPv6. Type: boolean

Default

false

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

`services.avahi.nssmdns4`

Whether to enable the mDNS NSS (Name Service Switch) plug-in for IPv4. Enabling it allows applications to resolve names in the .local domain by transparently querying the Avahi daemon.

Type: boolean

Default

false

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

`services.avahi.nssmdns6`

Whether to enable the mDNS NSS (Name Service Switch) plug-in for IPv6. Enabling it allows applications to resolve names in the .local domain by transparently querying the Avahi daemon.

::: {.note} Due to the fact that most mDNS responders only register local IPv4 addresses, most user want to leave this option disabled to avoid long timeouts when applications first resolve the none existing IPv6 address. :::

Type: boolean
