When I ssh as root from the headnode to a newly imaged node, here's what I get: Warning: No xauth data; using fake authentication data for X11 forwarding. /usr/X11R6/bin/xauth: creating new authority file /root/.Xauthority I think the xauth error message has constantly caused us grief - I would be in favour of fixing this for 4.1. > > [MANPATH] > The MANPATH bug seems to still be around.

I suggest that we up this bug to priority 9 such that we can have it looked at and fixed.

This is a good idea - we should put it down on the map :) Cheers, Bernard ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
