You can find the start and stop scripts of Linux services in the /etc/init.d/
directory. To start the standard DHCP daemon, use the /etc/init.d/dhcpd
start command. To restart the DHCP daemon, use the /etc/init.d/dhcpd
restart command.
The filename “install”; lines in the dhcpd.conf file point to a directory in the
/tftpboot directory. We show how to configure it in the next section.
Tip for Linux beginners: The following tasks help you to double-check or
troubleshoot a configuration in general.
To trace messages of running services, type tail -f -n 10
/var/log/messages to get the last 10 messages and auto update if there
are new messages.
Connect to a running service with a local client, remote client, or both these
clients and try to receive the data that you want.
Make sure a changed configuration is activated by restarting a service
directly after editing, for example:
a. vi /etc/dhcpd.conf
b. /etc/init.d/dhcpd restart
