[Fiware-lab-help] R: CentOS-7-x64 Image on Lannion2 does not allow ssh logins

[Cipriani Marco]

Dear Carlos,
I have just forwarded your request to the Lannion support team in order to solve the issue.
Meanwhile, please provide us your project ID (you can find it selecting your project name and looking at the info bar at the bottom of the page, something like <project-name> (ID 00000000000000000000000000000xyz).

Best regards
Marco

Oggetto: [Fiware-lab-help] CentOS-7-x64 Image on Lannion2 does not allow ssh logins

Dear all,

The Image "CentOS-7-x64" on Region "Lannion2" does NOT allow ssh login with the configured identity keypair.

Currently our instance

Name: nuberisim-compute-node
ID: 17c940ac-abb6-4fff-bf9e-55f7b8489f2c
Status: ACTIVE
node-int-net-01: 192.168.1.206<http://192.168.1.206>
Image Name: CentOS-7-x64
region: Lannion2

does not allow logins over ssh (Permission denied) - and does not even present a password prompt -
despite correct identity keypair configuration.

Any help with this problem would be appreciated.

Kind regards,

Carlos Falquez
