Hi Michelle:
The ssh error message means
that you cannot even connect to them via the network - are you having networking
problems?
Cheers,
Bernard

Bernard,
After I execute:
/opt/sync_files/bin/sync_files
I found that I can no longer get to some
of the slave nodes by ssh even with root!! it is scary... Shall I copy
/etc/passwd, /etc/group, and /etc/shadow from headnode to these clients nodes
that i had problem connect to?
Thanks,
Michelle

Hi Michelle:You just need to create the user account on the headnode (which updates /etc/passwd and /etc/shadow) and you can either wait for sync_files to push the files to the compute nodes (there is a cronjob which updates the password files regularly) or forcibly updating them by running:# /opt/sync_files/bin/sync_filesCheers,Bernard

Subject: [Oscar-users] how to add user to cluster
Hey,If I want to add a user to a cluster, it seems that I have to add user for each client node one by one. Say I have 8 client nodes, I have to do the same things for 8 times. Is there any way thatI only need to do once at the server node? Thanks, Michelle
