Manual Pages  — DHCLIENT.LEASES

NAME

dhclient.leases – DHCP client lease database

CONTENTS

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.

The lease file is named dhclient.leases.IFNAME, where IFNAME represents the network interface the DHCP client acquired the lease on. For example, if dhclient(8) is configured for the em0 network device, the lease file will be named dhclient.leases.em0.

The format of the lease declarations is described in dhclient.conf(5).

FILES

/var/db/dhclient.leases.IFNAME Current lease file.

As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.
