dhcp_lease_time \- Query remaining time of a lease on a the local dnsmasq DHCP server.
.SH SYNOPSIS
.B dhcp_lease_time <address>
.SH "DESCRIPTION"
Send a DHCPINFORM message to a dnsmasq server running on the local host
and print (to stdout) the time remaining in any lease for the given
address. The time is given as string printed to stdout.
If an error occurs or no lease exists for the given address,
nothing is sent to stdout a message is sent to stderr and a
non-zero error code is returned.
Requires dnsmasq 2.40 or later and may not work with other DHCP servers.

.TH DHCP_RELEASE 1
.SH NAME
dhcp_release \- Release a DHCP lease on a the local dnsmasq DHCP server.
.SH SYNOPSIS
.B dhcp_release <interface> <address> <MAC address> <client_id>
.SH "DESCRIPTION"
A utility which forces the DHCP server running on this machine to release a
DHCP lease.
.PP
Send a DHCPRELEASE message via the specified interface to tell the
local DHCP server to delete a particular lease.
The interface argument is the interface in which a DHCP
request _would_ be received if it was coming from the client,
rather than being faked up here.
The address argument is a dotted-quad IP addresses and mandatory.
The MAC address is colon separated hex, and is mandatory. It may be
prefixed by an address-type byte followed by -, eg
10-11:22:33:44:55:66
but if the address-type byte is missing it is assumed to be 1, the type
for ethernet. This encoding is the one used in dnsmasq lease files.
The client-id is optional. If it is "*" then it treated as being missing.
.SH NOTES
MUST be run as root - will fail otherwise.
