The DHCP client normally exits if it isn't able to identify any
|
||||
network interfaces to configure. On laptop computers and other
|

computers with hot-swappable I/O buses, it is possible that a
|
||||
broadcast interface may be added after system startup. The

.B -w
|

flag can be used to cause the client not to exit when it doesn't find
|

any such interfaces. The

.B dhcpccp (8)
|
||||
program can then be used to notify the client when a network interface
|

has been added or removed, so that the client can configure an IP

address on that interface.
