2. Setting up the Configuration File ddns-update-style interim; Ignore client-updates; Subnet 10.0.0.0 netmask 255.255.255.0 { option routers10.0.0.1; option domain-name-servers 10.0.0.1; option subnet-mask255.255.255.0; option domain-name “handsonhistory.com”; Range 10.0.0.15010.0.0.255; Default-lease-time21600; Max-release-time43200; Host ns { Next-server ns1.handsonhistory.com; Hardware ethernet 00:D0:B3:79:B5:35; Fixed-address 10.0.0.1; } Do not update update DNS records for the local domain based on the IP address it assigns. Represents the network, other data in this file define what information the DHCP server will hand out to clients on this LAN. Sets default router and DNS.

4. Leases /var/log/messages contains troubleshooting information for DHCP. /var/lig/dhcpd/dhcpd.leases If a client has been assigned an IP address, a least line should be in that file. Leases Starting Server # service dhcpd start Clients # dhclient (interface) # dhcpd (interface) Or the GUI.
