check to make sure the home directories are being mounted by the compute nodes
via nfs. the reason you cannot log in with ssh keys is they're stored in your
homedir and the compute node isn't mounting it properly.

Subject: Re: [Oscar-users] user add another question
no question is silly - just the question that is not asked. Here is
what I get when I try to log in as a test user:
[EMAIL PROTECTED] ~]$ ssh oscarnode1
[EMAIL PROTECTED]'s password:
Last login: Fri Sep 12 12:43:02 2008 from madrid.ucmerced.edu
Could not chdir to home directory /home/joseph: No such file or directory
-bash: cd: /home/joseph: No such file or directory
cannot cd to home directory /home/joseph
but this is strange because when I log in as root I can move from head
node to compute node and home has been mounted
