To create a +service of this type, you must supply a @code{<dhcpd-configuration>}. +For example: + +@example +(service dhcpd-service-type + (dhcpd-configuration + (config-file (local-file "my-dhcpd.conf")) + (interfaces '("enp0s25")))) +@end example +@end deffn + +@deftp {Data Type} dhcpd-configuration +@table @asis +@item @code{package} (default: @code{isc-dhcp}) +The package that provides the DHCP daemon. This package is expected to +provide the daemon at @file{sbin/dhcpd} relative to its output +directory. The default package is the +@uref{http://www.isc.org/products/DHCP, ISC's DHCP server}. +@item @code{config-file} (default: @code{#f}) +The configuration file to use. This is required. It will be passed to +@code{dhcpd} via its @code{-cf} option. This may be any ``file-like'' +object (@pxref{G-Expressions, file-like objects}). See @code{man +dhcpd.conf} for details on the configuration file syntax. +@item @code{version} (default: @code{"4"}) +The DHCP version to use. The ISC DHCP server supports the values ``4'', +``6'', and ``4o6''. These correspond to the @code{dhcpd} program +options @code{-4}, @code{-6}, and @code{-4o6}. See @code{man dhcpd} for +details. +@item @code{run-directory} (default: @code{"/run/dhcpd"}) +The run directory to use. At service activation time, this directory +will be created if it does not exist. +@item @code{pid-file} (default: @code{"/run/dhcpd/dhcpd.pid"}) +The PID file to use. This corresponds to the @code{-pf} option of +@code{dhcpd}. See @code{man dhcpd} for details. +@item @code{interfaces} (default: @code{'()}) +The names of the network interfaces on which dhcpd should listen for +broadcasts. If this list is not empty, then its elements (which must be +strings) will be appended to the @code{dhcpd} invocation when starting +the daemon. It may not be necessary to explicitly specify any +interfaces here; see @code{man dhcpd} for details. +@end table +@end deftp + @defvr {Scheme Variable} static-networking-service-type This is the type for statically-configured network interfaces. @c TODO Document <static-networking> data structures. |
