Both Per Hedeland <> and Brett Lymn <>
assured me that it DOES work on their Sites. And out of the Blue, it
started working over here, too. (I recognized that when I tried to install
the mentioned Test Client, which I still hadn't put back into securenets. ;-)

I have no Idea what went wrong. Yes, I *did* *reboot* after having put
securenets in Place, I had a Series of Kernel Patches to get going and
wanted to go single User for 101508-06. However, the Server had one or
the other Problem with File Ownerships (the mentioned Migration) and
Permissions; I can't tell why this would affect /var/yp/securenets, but
*maybe* ypserv couldn't read securenets on the first Try.

SUN, are you listening? I would welcome a ypserv which SHOUTS OUT LOUD
upon not finding / being able to read securenets when it's started.
Gives Upgraders a Chance to learn about that Patch, too.
