[one-users] Deployment files transfer error

Tue Sep 30 05:06:48 PDT 2014

Hello again,

I've resolved the problem in one host.

As I said in a previous message, I had access errors in the directory
/var/lib/one/.ssh after mounting /var/lib/one in the remote host with NFS.

The problem was the fact that the oneadmin user id wasn't the same as the
oneadmin user id in the front-end host so ONE couldn't access the ssh
configuration and hosts couldn't comunicate each other without entering the
password.

Now I have a doubt. Since the directory that is mounted is /var/lib/one
from the front-end host, at the end, the directory is the same in the
remote host and oneadmin has the same ssh key. Is this correct?

Thank you very much,

Best regards
