I\'ve just setup my EC2 server following this video here exactly - http://www.youtube.com/watch?v=bBajLxeKqoY
I even chose the same server type, everything went well
I am using TurboLinux instance, on Mac OS system, please try this command: ssh -i xxxxx.pem root@xxx.xxx.xxx.xxx (public address of allocated VM) I can get through without asking password anymore.
