Linux – Net::SSH::AuthenticationFailed when using Chef’s Knife ssh

amazon ec2chefchef-sololinux

Facts:

  1. I have a Chef server installed.
  2. I have registered a node to this server, and I can see the node in the webUI (This is an existing node, NOT bootstrapped using knife bootstrap

  3. When I execute the command

    $ knife ssh "role:test" "sudo chef-client"
WARNING: Failed to connect to node[ip-X-X-X-X.ec2.internal] -- Net::SSH::AuthenticationFailed: ubuntu@ip-X-X-X-X.ec2.internal

Is there something I have missed? e.g. copy the SSH keys?

Best Answer

This problem is usually caused by not having the right private key PEM file added to your local ssh agent. Doing something like:

$ ssh-add pk-XXXX

Where the argument is the private part of the key pair used to create the EC2 instance.
