SSH Connectivity failed from node2 to node1

Postby 1982 » Wed Jul 23, 2014 9:32 am

Hi Tim,

OS: RHEL 5
DB Version:- 11.2.0.1.0

Today i am trying to configure RAC on RHEL. After configuring both nodes as per your blog
http://www.oracle-base.com/articles/11g ... rver-2.php.

When i run the ./runInstaller. It works fine till SSH connectivity. After setup when i try to test the SSH connectivity i am getting error as ins-06006 passwordless ssh connectivity not set up between the following node.

I check both node ping each other.

i also disable the firewall as well on both nodes.

Kindly Advice over the same

Now i need to manually configure the SSH connectivity using authorization key or what i need to do to sort out this problem.

Hi.

Are you attempting the SSH setup using the installer? If so, what message is it giving you about the failure?

Things to check:

- Pings between nodes.
- Firewall is disabled.
- SELinux is set to permissive.

You might find it easier to get to the root of the problem by setting it up manually, as you will probably get better error messages that way. There are two methods explained here.
