dhcpleasedDynamic Host Configuration Protocol (DHCP) client

dhcpleased [-dnv] [-f file] [-s socket]

dhcpleased is a dynamic host configuration protocol (DHCP) daemon for clients. It requests IP configuration information from for example those offered by dhcpd(8), on interfaces with the flag set. See hostname.if(5) and ifconfig(8) on how to enable auto configuration on an interface.

dhcpleased monitors network interface states (interface going up or down, auto configuration enabled or disabled etc.) and sends requests when necessary.

A running dhcpleased can be controlled with the dhcpleasectl(8) utility.

The options are as follows:

Do not daemonize. If this option is specified, dhcpleased will run in the foreground and log to .
Specify an alternative configuration file.
Configtest mode. Only check the configuration file for validity.
Use an alternate location for the default control socket.
Produce more verbose output. Multiple -v options increase the verbosity.

UNIX-domain socket used for communication with dhcpleasectl(8).
Default dhcpleased configuration file.
Interface specific lease files.
