Once your configuration has been saved in /etc/dhcpd.conf , restart dhcpd to activate it using the Services graphical tool or this command:

# service dhcpd restart

If there are errors in your configuration file, dhcpd may not start. Check the end of the file /var/log/messages to see if there are any error messages:

# tail -50 /var/log/messages|less

If there are no error messages, clients can begin using the dhcpd server to obtain their IP addresses.

You will need to open port 68 UDP in your firewall configuration in order to permit clients to reach dhcpd. You should also verify that no other DHCP servers are running on your network (check router and gateway appliances in addition to computers). 

If configured to obtain IP information through DHCP, the client systems will contact the DHCP server when
