(note the trailing dot, I think the jury is still out on that one ;-) Nobody is meant to request recursive lookup for 127.0.0.1, although many configurations do, of course. They deserve what they get, don't they? Lastly, the idea was to get rid of the delay and failure in the revcerse l.ookup, which I believe is not achieved by the suggested /lib/ndb/local (why not /lib/ndb/common?) entry. ++L --upas-rvkhpthcebfwxtwhcvqbqzftlr--
