The phenomenon was that a local ypbind couldn't contact the local or any remote ypserver and it disappeared exactly then when removing the i686 option (and not changing anything else!). Well, I tried nearly everything for about one week and only removing this flag helped. I will do this again, maybe it was a phenomenon on "moving" code from 4.2 to 4.3? I do not know ... I would only mention this here because it pushed me in trouble nobody could help me for the past days. Thank you for responding. :>On Wed, Mar 07, 2001 at 09:30:33AM +0100, Hartmann, O. wrote: :>> Dear Sirs. :>> :>> I'm really confused and surprised by the fact, that with the upcoming new :>> FreeBSD 4.3 in its make.conf we can choose architectural parameters for the :>> CPU architecture.
