Become superuser on the DHCP server system.
Type the following commands to stop the DHCP daemon and restart it in verbose mode:
# /etc/init.d/dhcp stop # /usr/lib/inet/in.dhcpd -v options
where options are any other options you normally use to start the daemon.
The daemon runs in verbose mode for this session only.
Verbose mode can reduce daemon efficiency because of the time taken to display messages.
