Troubleshooting
Problem
The upgrade and instance creation wizards might fail with authentication failure after entering the instance userid and password while SSH protocol is setup and user connection works fine with SSH.
Symptom
The dsmicfgx.trc or dsmupgdx.trc shows error like below:
at java.awt.EventDispatchThread.run(EventDispatchThread.java:133)
Caused by: com.ibm.tivoli.remoteaccess.RemoteAccessAuthException: CTGRI0000E Could not establish a connection to the target machine with the authorization credentials that were provided.
at com.ibm.tivoli.remoteaccess.SSHProtocol.beginSessionImpl(SSHProtocol.java:757)
at com.ibm.tivoli.remoteaccess.BaseProtocol$BeginSession.invoke(BaseProtocol.java:1755)
at com.ibm.tivoli.remoteaccess.util.ThreadedOperation$OperationThread.run(ThreadedOperation.java:154)
Caused by: java.net.ConnectException: AUTHENTICATION_FAILED
Cause
SSH is setup using ssh keys. SSH password authentication must be active.
Environment
AIX, HP-UX, Linux and Solaris
Diagnosing The Problem
Look in dsmicfgx.trc or dsmupgdx.trc if these messages appear:
CTGRI0000E Could not establish a connection to the target machine with the authorization credentials that were provided.
[....]
Caused by: java.net.ConnectException: AUTHENTICATION_FAILED
Then try to connect to the instance user, using SSH. If it does not prompt for password , that is a problem.
Also look in file /etc/ssh/sshd_config if the entry "PasswordAuthentication" is set to "no".
Resolving The Problem
Look at the system SSH documentation how to enable SSH password authentication at least for the time the wizard needs to be used.
