From your output it looks like the banner is causing the problem.
The section "ssh flux-rac-node-wcdp-02 ls -l /tmp" and it returns the warning. That's the first place to start.

Subject: RACnode communication problem?
I'm trying to install RAC 11.2.0 - Linux-x86-64, RedHat 5.3, oracle 22.214.171.124.0 (fyi - I also tried with 126.96.36.199.0 and got the same result)
Has anyone seen this before, and have a solution? runcluvfy.sh and runInstaller complain that the nodes can't talk to each other, but I can ssh (passwordless) between them and oracle has even copied files from node1 to the other nodes in /tmp. I believe there is nothing wrong, but need to figure out why oracle suddenly thinks something is wrong.
BTW, yesterday, it wasn't complaining at all, but the servers were rebooted last night. It works fine when I do things manually, but oracle doesn't seem to think it works. I'm hoping I'm either doing something "RAC newbie" or it is just a weird oracle thing
Here is what runcluvfy says (and runInstaller) (note: yes, changed the a/b on network so I don't get in trouble)

I've checked ifconfig and everything looks fine, and here you can see I can ssh between them (and yes, I've done it both ways). Also, the runcluvfy.sh apparently is able to connect over because when I run it, node2 gets oracle files created in /tmp.
