Hi,

Can you tell me what are you doing to log in your Orion VM? Anyway, I'm providing you a couple of tips:

1. The user for orion hosts is "centos"
2. You need a valid public key in order to login from the host you are trying to login. As your Orion VM has only a private IP, you have done a previous SSH.

Hope this help, if not, please come back to us giving us some more detail.

Regards,
José Ignacio.

I think you've setup another ticket for another user with your same account, please, let us try to solve this as one:
https://jira.fiware.org/browse/HELP-8098

Hi,

After you gave me access to your VM with your private key cbkey.pem, I managed to login your VM —

You had changed the file: /etc/ssh/sshd_config so you managed to make ssh unusable. I've recovered your original sshd_config file.

If you set your AuthorizedKeysFiles to another location, make sure you can access it. Please, take a look at secure.log
