I set up an EC2 instance using the Amazon AMIs (I believe based on redhat/centos) I set up my security profile to allow 22, and verified it works because I can SSH in just fine using putty and the ppk I created.

SFTP on the other hand is a no go. When I try to SFTP in I get the following response:

Connecting
[SFTP] Host key accepted
[SFTP] Successfully authenticated
[SFTP] Error initialising sftp: Received a 115 messages instead of SSH_FXP_VERSION
Unable to connect
 Disconnected

Of course, google has been little to no help. Any thoughts?

You will need to use the .pem version of your private key, not the .ppk when authenticating with Notepad++.

I ran into the same issue you did when using .ppk, however, when I converted the .ppk back to .pem using puttygen, I was able to authenticate with the server.

Here is more info on using puttygen to convert your key back to .pem in case no longer have that format: http://www.techyforums.com/index.php?showtopic=80

Try setting your user userid in Notepad++ to . If you have it set to "root" you will get the 115 error. I put in the password too so Notepad++ doesn't pester me asking for a password. Because you are using an auth key, the password is irrelevant.

look at /root/.ssh/authorized_keys you most likely have this kind of thing :

> no-port-forwarding,no-agent-forwarding,no-X11-forwarding,command="echo
> 'Please login as the user \"ubuntu\" rather than the user
> \"root\".';echo;sleep 10" ssh-rsa AAAAB3[yourkey]

Get rid of everything in front of ssh-rsa and the root stuff will work.
