# Again, enter the command to list all the files installed from the DHCP server package by issuing the command: <b><code><span style="color:#3366CC;font-size:1.2em;">rpm -qla dhcp</span></code></b>

# Copy While you could copy the '''dhcpd.conf.example''' file to the '''/etc/dhcp/dhcpd.conf''' directory making sure , it is named: recommended that you start a new '''/etc/dhcp/dhcpd.conf'''from scratch.
