GI runInstaller Fails with INS-6006 in VNC During SSH test even though SSH Setup is successful (Doc ID 2070270.1)

APPLIES TO:

Oracle Database - Enterprise Edition - Version 11.2.0.4 and later
Information in this document applies to any platform.

SYMPTOMS

11.2.0.4 Grid Infrastructure installation on RHEL 6  fails with INS-06006 during SSH Test, even though SSH Setup shows successful message and ssh <node> date command works fine for all nodes in the Putty session.

INS-06006 Passwordless SSH connectivity not set up between the following node(s): [racnode1, racnode2]

If click "Next", then the following error is reported:

SEVERE: [FATAL] [INS-30132] Initial setup required for the execution of installer validations failed on nodes: racnode1, racnode2
 CAUSE: Indicated nodes were not reachable or failed to access the temporary location on the indicated nodes.
 ACTION: Ensure that all the indicated nodes are reachable and current user has required permissions to access the temporary location on all the indicated nodes.

  

CAUSE

Problem with SSH setup in the VNC session.
 
Even though in Putty session the command ssh <node> date or ssh <node> /bin/true return without error, the OUI session which is initiated from VNC server reports the following error when running with "-debug -Loglevel finest":

Agent admitted failure to sign using the key.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

Test ssh <node> /bin/true from the terminal in VNC session reports the same error.
 

SOLUTION

Clean up the files in .ssh directory for grid user in VNC session:

cd $HOME/.ssh
rm -rf *

In the OUI session, click SSH "Setup" again to setup SSH for grid user from scratch,
then click "Test" in OUI,
Now it completes with "SSH for user grid has already been setup".

Click "Next" in the OUI to complete the installation.
