|
|
.Sh DESCRIPTION
|
|
The Internet Software Consortium DHCP client keeps a persistent
|
|
database of leases that it has acquired that are still valid.
|
|
The database is a free-form ASCII file containing one valid declaration
|
|
per lease.
|
|
If more than one declaration appears for a given lease,
|
|
the last one in the file is used.
|
|
The file is written as a log, so this is not an unusual occurrence.
|
|
.Pp
|
|
The lease file is named
|
|
.Pa dhclient.leases . Ns Ar IFNAME ,
|
|
where
|
|
.Ar IFNAME
|
|
represents the network interface the DHCP client acquired the lease on.
|
|
For example, if
|
|
.Xr dhclient 8
|
|
is configured for the
|
|
.Li em0
|
|
network device,
|
|
the lease file will be named
|
|
.Pa dhclient.leases.em0 .
|
|
.Pp
|
|
The format of the lease declarations is described in
|
|
.Xr dhclient.conf 5 .
|
|
.Sh FILES

|
.Bl -tag -width ".Pa /var/db/dhclient.leases. Ns Ar IFNAME"
