They won't need to be if you use DNS. But it is acceptable to list them in the local files.

NIS/YP for host information is obsolete. It is a holdover from before DNS became the dominant protocol. Having the same data in both places means that they can get out of sync and that leads to confusion. The DRY principle here is don't repeat yourself. > Nevertheless I don t understand how the nfs can make a > resolution via dns of a a client whith a private > address The NFS mountd will call gethostbyaddr(3). man 3 gethostbyaddr If the information is not available it will fail.
