Comment by mario.scalabrino@yahoo.it :

Dear Daniele,

all solved, thank you very much for your fast and professional
assistance, few people nowadays can be so effective.

1. Understood.

2. I added in /etc/hosts the missing line as described in your link. Solved.

3. I read all the slides, then I opened the 3389 port that is the RDP's
one in the security group rules. I can see the desktop now from the
terminal. Solved.

Cheers

Have a good evening

Mario

Dear,

1) The reason why you are not able to ping the public IP could be that the ICMP protocol is closed on the security group. Moreover if you are able to connect via SSH I exclude any network issue on the infrastructure.

2) This problem is probably strictly related to the configurations of your instance. It should not have serious drawback, but if you want to solved have a lot here: http://askubuntu.com/questions/59458/error-message-when-i-run-sudo-unable-to-resolve-host-none

3) Again the issue is probably related to the configuration of the security group. Try to open the port used by RDP on your instance from the security group panel: Check from page 25 of http://www.slideshare.net/flopezaguilar/setting-up-your-virtual-infrastructure-using-fi-lab-cloud-32388357

Best,
Daniele
