Also SL 6.3 shipped with a defective libtirpc which discards UDP broadcast packets. The bug makes NIS not work. May bite you, too. SL 6.2 or 6.1 was okey, I think, SL 6.4 not sure. I have posted this bug on this mailing list and on RH bugzilla, it is fixed in errata packages. -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
