Hello Bernard, Ok so then I think we have found a problem. When I install Linux (Redhat a coupld years ago and now Mandrake), I always decline to make graphical mode the default boot level. When the system boots I get a text login, and I normally login in under a user account and then "startx". That's standard right? And it seems odd that OSCAR does not support that. And the only way I know how to change it is to reinstall Mandrake Linux. Or if it is as simple as changing the run level in one of the start up scripts then maybe I can do that.
Please understand that except for making graphical mode the default boot leve, I have already tried what you suggest below and step 8 of the OSCAR wizard appears to fail quite quickly (fraction of a second). And so I wonder if I will be wasting my time trying anything else with OSCAR under Mandrake 9.0 only to find the everyone who gets OSCAR to work without too much trouble does it using Redhat 9.0. Could it be that what I have been describing is actually a bug in the installation and testing of OSCAR under Mandrake? And can you please comment on the "mkstemp" and "rsync error" messages I have been asking about? Do any of the following suggestions that I have received address that? * cexec mount /home (tried that - already mounted) * fix ~/.ssh permissions (~/.ssh is u+rx and all files readable) * create user accounts and push them with OPIUM (doesn't ./install_cluster do that?) * change the default boot level to graphical mode (reinstalling Linux?) If reinstalling Linux with graphical mode as the default boot level will fix my problem then I will do it. Should I do it? And should I switch from Mandrake 9.0 to Redhat 9.0 if that will make things smoother?
