[Bug 613022] [NEW] ssh daemon hangs after publickey packet sent

[Scott Moser]

Public bug reported:

A launched ec2 instance in ap-southeast-1 region is unreachable via ssh.
$ ssh -vvv ec2-175-41-171-225.ap-southeast-1.compute.amazonaws.com
shows progress up to :

debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering public key: smoser at brickies
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply

Then nothing for minutes before session is killed (manually).

In a 'good' connection, the following would be next:
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey

I'll attach full 'ssh -vvv' logs good and bad connection.
