Issue on the Ubuntu Zesty Scaleway image #14

Closed wblondel closed 6 years ago

wblondel commented 6 years ago

Hi,

I just tried to install the playbook on a Ubuntu Zesty image on Scaleway, it stopped at TASK [iri : ensure ufw started] and it actually locked me out of the server. I can't connect anymore via SSH.

ssh: connect to host ***** port 22: Operation timed out

Looks like the script messed up the firewall configuration.

I tested with Ubuntu Zesty this image: https://cloud-images.ubuntu.com/releases/17.04/release/ (64 bit cloud image) and didn't have this issue.

If you look here, you'll see that the playbook is first ensuring that ssh port is allowed, only then enable ufw: https://github.com/nuriel77/iri-playbook/blob/master/roles/iri/tasks/ufw.yml#L23 Which prevents this scenario.

Anyway, I've done some googling about ufw + scaleway. It seems that scaleway use nbd (network block device) and it might be the case that it is what is crashing the server/dropping the connection for you.

Have a look here: https://community.online.net/t/how-to-configures-iptables-with-input-rules-with-dynamic-nbd/303/22

This is the fix to get ufw running with scaleway baremetal servers :)
