Solving Problem : using putty, connecting to Amazon EC2

There is a trick if your pem file converted to ppk (putty's private key) and the server respond is :
Server do not accept our key or something similar like that, server send public key etc..

On one blog i find that we need to open the pem file on a notepad and then add one line to the last line, so make sure you get your cursor under those texts..

One line is enough ;)

Now get to putty again, (i'm using ubuntu) so when the putty ask :"Login As" i answered Ubuntu and voila.. we get our self a great powerful cloud server
