Subject: [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
