I currently have three AWS instances (all running Ubuntu 14.04 LTS) - as well as the default "ubuntu" user created by AWS, I set up another admin user and use a public key specifically for that user from my laptop (Ubuntu 16.04 LTS). So far so good - never had a problem.
Now, I've just created a new instance with 16.04 LTS. I ended up having to cut a new key pair for the ubuntu user when setting up the server as the original pair used for the other didn't seem to work.
I've created a new user on the new instance and have been trying to get publickey authentication working here, too. I can log in as the new user after connecting as the ubuntu user and using the
I keep getting the following when trying to connect as this user from my laptop:
debug1: Offering RSA public key: /home/horuskol/.ssh/id_rsa debug3: send_pubkey_test debug3: send packet: type 50 debug2: we sent a publickey packet, wait for reply debug3: receive packet: type 51 debug1: Authentications that can continue: publickey debug2: we did not send a packet, disable method debug1: No more authentication methods to try.
Note - this is the same certificate I'm using for the other three servers and still don't have a problem there
I've checked permissions on the remote server:
/home/horuskol horuskol horuskol drwxr-xr-x /home/horuskol/.ssh horuskol horuskol drwx------ /home/horuskol/.ssh/authorized_keys horuskol horuskol -rw-------
I triple checked that the authorized key on the remote server matched the local public key.
I've even copied the authorized_keys file across from one of the working servers.
Eventually, I created a new public/private key (id_rsa_2017_01) and copied the new public key to the new server.
Nothing has worked so far.
