Of all the gin joints in all the towns in all the world, Christoph

Then you did change the NIS master's hostname after all. That's what
I said originally. /var/yp/Makefile figures out the hostname to encode
in the map by calling hostname(1), so if you change your hostname you
need to rebuild all your maps. (Note that yp_mkdb(8) will also grab
the hostname with gethostname() if you don't supply a hostname on
the command line -- this should amount to the same thing.)

At some point, you decided to go from 'toots' to 'toots.physik.rwth-aachen.de'
(no, don't deny it: the proof is right there :). This makes the value returned
by gethostname() different than what it was when you first built the maps.
So just touch all your map source files (/var/yp/master.passwd, /etc/group,
etc...) and then cd /var/yp; make. rpc.yppasswdd should start correctly then.

Again, I suppose I should make the error message more specific. :)
