# NAME

`dhcpleased` — Dynamic Host Configuration Protocol (DHCP) client

# SYNOPSIS

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

# DESCRIPTION

`dhcpleased` is a dynamic host configuration protocol (DHCP) daemon for clients. If an interface has the AUTOCONF4 flag set (auto configuration is enabled), `dhcpleased` sends requests for IP configuration information from a DHCP server, such as dhcpd(8), and uses that information to configure the relevant interface.

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:

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

  UNIX-domain socket used for communication with dhcpleasectl(8).
