I have created a Ubuntu 12.04 instance on Amazon EC2.
I have downloaded the PEM file and am able to SSH into the instance, no problem.
Now, I want to create some accounts on the remote instance for consultants, etc. They should be able to ssh into the box using RSA keys. On the EC2 machine, I have set up a few accounts in ~/home/ and assigned them to the group admin. I have also given myself a similar account (MyTestAccount) for testing. This is what I did:
I used key-gen to create public and private keys in the .ssh directory on my local machine (~/.ssh):
drwx------ 2 peter peter 1024 Sep 14 10:23 .ssh
And the files inside:
-rw------- 1 peter peter 1675 Sep 14 10:23 id_rsa
-rw------- 1 peter peter 394 Sep 14 10:23 id_rsa.pub
-rw------- 1 peter peter 444 Sep 14 00:05 known_hosts
I then SCP'd the id_rsa.pub file to my remote EC2 instance and appended it to the .ssh/authorized_keys file in my remote instance. The permissions of my remote .ssh directory:
drwx------ 2 ubuntu ubuntu 4096 Sep 16 16:13 .ssh
And of my authorized_keys file:
-rw------- 1 peter ubuntu 1179 Sep 14 00:05 authorized_keys
Next, I logged off my remote instance and attempted to SSH to the remote box using the new keys. When I issue the following command:
peter@ubuntu:~/.ssh$ ssh -vvv [email protected]
I get the below. Does it look like there is something wrong with my private key? Any suggestions?
