When executing tpm, ssh is used to connect and install the software on other hosts in the cluster. If this fails, and the public key information is correct, there are a number of operations and settings that can be checked. Ensure that you have followed the Section B.3.3.2, “SSH Configuration” instructions.
The most likely representation of this error will be when executing tpm during a deployment:
Error: ##################################################################### Validation failed ##################################################################### ##################################################################### Errors for host1 ##################################################################### ERROR>>host1>>Unable to SSH to host1 as root. (SSHLoginCheck) Ensure that the host is running and that you can login as root via SSH using key authentication tungsten-configure.log shows: 2012-05-23T11:10:37+02:00 DEBUG>>Execute `whoami` on host1 as root 2012-05-23T11:10:38+02:00 DEBUG>>RC: 0, Result: stdin: is not a tty
Try running the following command:
shell> ssh tungsten@host1 sudo whoami
If the SSH and sudo configurations have been
configured correctly, it should return
root. Any other value indicates
a failure to configure the prerequisites properly.
Check that none of the profile scripts
(.profile,
.bash_profile,
.bashrc, etc.) do not contain
a call to mesg n. This may fool the non-interactive
ssh call; the call to this command should be
changed to only be executed on interactive shells:
if `tty -s`; then mesg n fi
Check that firewalls and/or antivirus software are not blocking or preventing connectivity on port 22.
If ssh has been enabled on a non-standard port, use
the --net-ssh-option=port option to
specify the alternative port.
Make sure that the user specified in the
--user to tpm is allowed to connect
to your cluster nodes.
