Associating the ypdomain with the FQDN from the DNS is convenient, and a convention that many follow, but it is not required, by any means. The O'Reilly "Managing NIS and NFS" book is a fine reference on this sort of thing, BTW, and is probably available online in PDF form if you look. Nevertheless, YP/NIS predates many of the more convoluted network designs that people set up nowadays, and was intended for machines which have a single identity even if they have multiple NICs-- Sun used to assign the same MAC address to all NICs on one machine, to ensure that people respected collision domains. It is not normally desirable to set up a YP/NIS master server on a machine which is multihomed in the sense of doing NAT or needing a firewall to separate internal from external, and obvious a firewall machine running zero or the minimal necessary services is a lot more secure.... -- -Chuck
