	      services that appear in access control rules but are not controlled by

	      services that should not be wrapped,

	      non-existent host names or non-internet address forms,

	      occurrences of host aliases instead of official host names,

	      hosts with a name/address conflict,

	      inappropriate use of wildcard patterns,

	      inappropriate use of NIS netgroups or references to non-existent NIS netgroups,
