	Gregor,

	I found that it was my lines in /etc/inetd.conf that was at fault....

#sane           stream  tcp     nowait  saned.saned     /usr/sbin/saned saned
sane            stream  tcp     nowait  root.root     /usr/sbin/saned saned

	The commented line is the original, the second is the one that worked for 
me. Hope this helps.
