It'd be helpful to see the exact error message. I wrote this up after hitting some problems myself, might be worth reviewing: http://tinky2jed.wordpress.com/technical-stuff/oracle-stuff/prvf-7616-node-connectivity-failed-for-subnet-between-and/ I just noticed your comment on node 2 asking for a password. Maybe your ssh setup is not correct on that server. You might want to review it, you shouldn't get prompted for a password. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Radoulov, Dimitre Sent: Tuesday, October 23, 2012 2:45 AM To: sjwales@xxxxxxxxxxx Cc: oracle-l@xxxxxxxxxxxxx Subject: Re: SSH Connectivity Fail during RAC install On 23/10/2012 01:44, Steve Wales wrote: > Further to the below: > > We've discovered that if we do the following from an SSH window using > putty on node1: > > Ssh node1 date > Ssh node2 date > > It works. > > Doing the same thing from a terminal window from the console with the > GUI, > node1 works, node2 prompts for a password. > > Since the installer is running from the console GUI terminal window, > it thinks it's broken and fails. Are you using role separation (different users for GI and Database)? Please post the output (exactly, just copy/paste) of the following commands: node1$ id node1$ ssh node1 date node1$ ssh node2 date node2$ id node2$ ssh node1 date node2$ ssh node2 date Then repeat the command that doesn't work as expected (the command that receives the password prompt) with -v: ssh -v node2 date Regards Dimitre -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
