Yes, first try RTFM - 'man dhcpd.conf'. Then try looking as far back
as last week in the mailing list archive where essentially the same
question has been answered.
In short :
Define the hosts you want to allow to boot, as in :
host client1 { hardware ethernet aa:bb:cc:dd:ee:ff ; }
Then only allow those clients to boot. You can do this various ways,
but the quietest will be to add :
ignore unknown-clients :
to the pool or subnet declaration.
You can use "allow known-clients", but then you get log messages for
all the ones it doesn't service, "ignore" avoids these log messages.
