# Sample configuration file for LTSP dhcpd
# The goal of this provided dhcpd.conf is to boot as many different clients as possible without manual configuration.
# Some clients cannot be booted with this, and you will need to create your own custom dhcpd.conf.
# Some more complex network topologies will also need a custom dhcpd.conf.
