Re: SSH on all nodes

Hello Rayson,

I used the Linux free AMI listed on

www.aws.amazon.com/amazon-linux-ami/

currently just trying the first one listed - ami-7c807d14
<https://console.aws.amazon.com/ec2/v2/home?region=us-east-1#LaunchInstanceWizard:ami=ami-7c807d14>

Tried most of the EBS backed variants -

If I get a "Permission denied - public key" when ssh'ing and the
node/master in the console appears to be fine- what would be the next steps?

I terminated the cluster, and I tried creating a new keypair and key and
updated keys in the console the config file- restarted the cluster, the
instances started up and terminated fine from starcluster but still was not
able to ssh into the master or node using the new key.

Thanks in advance for your advisement

David


Thanks,
