If you run xdm, it sets up the Yes and no :-) I don't run xdm on beta (yet). -- I was just too naive to expect that the xauth trick would work. However, I _do_ run it on gluon and (right now at home) on ghost (2.1.5-R, but X11 still from 2.1.0-R). The .Xauthority file is created nicely everytime I log in.

Not only on ghost, but also on gluon and beta. It just found that only the 'ghost/unix:0' line is really new. Thus, obviously it is no longer possible just to copy .Xauthority from one machine to the other or simply to NFS-share the home directory. One needs to add explicitly the 'ghost:0' entry. Is this a bug or a feature (in some lib ?) ? Can someone verify this please ? (xdm(of 2.1.0 or 2.1.5) on 2.1.5 (non-DES), DISPLAY to <hostname>:0, e.g. xhost as test client from host <hostname> and preferrably some other, check list of entries in .Xauthority) > xauth authorization automatically for you.
