NAME
dhcpleased.conf —
DHCP client configuration
file
DESCRIPTION
The dhcpleased(8) daemon is a dynamic host configuration protocol client daemon.
The dhcpleased.conf config file is divided
into the following main sections:
- Macros
- Definitions of variables that can be used later, simplifying the configuration file.
- Interfaces
- If an interface requires non-default options, they can be defined in this section. Most configurations do not require this.
Macros
A macro is defined with a command of the form
name=value. The macro
name can contain letters, digits, and underscores and
cannot be a reserved word (for example, interface).
Within unquoted arguments, the string $name is later
expanded to value.
Interfaces
A list of interfaces to overwrite defaults:
interfacename {option ...}-
interfaceoptions are as follows:ignore dns- Ignore nameservers from leases on this interface. The default is to not ignore nameservers.
ignore routes- Ignore routes from leases on this interface. The default is to not ignore routes.
ignoreserver-ip- Ignore leases from server-ip. This option can be listed multiple times. The default is to not ignore servers.
prefer ipv6- Send the IPv6-Only preferred option to the server. If the server responds with the option, no lease is configured.
send client idclient-id- Send the DHCP client identifier option with a value of
client-id. If client-id
consists of a series of octets of two-digit hexadecimal numbers
separated by colons, the first octet is used as the type and the rest
as value. The MAC address 00:53:FF:AA:BB:CC would be configured as:
send client id "01:00:53:FF:AA:BB:CC"
Otherwise the string client-id is sent verbatim. The default is to send the interface's MAC address as client identifier.
When client-id is not a hardware address, it is supposed to be sent as hardware type 0 but the majority of DHCP clients and servers do not implement this and neither does
dhcpleased.conf. If a server is encountered that requires this, a 0 byte can be encoded as \0. The client identifier “foobar” with hardware type 0 would be configured as:send client id "\0foobar"
send host namehost-name- Send the DHCP client host name option with a value of host-name. The default is to send the name of the host.
send no host name- Do not send a DHCP host name option. The default is to send a DHCP host name option with the name of the host.
send vendor class idvendor-class-id- Send the DHCP vendor class identifier option with a value of vendor-class-id. The default is to not send a vendor class identifier.
