Title:
  ssh daemon hangs after publickey packet sent

Status in “cloud-init” package in Ubuntu:
  Confirmed
Status in “linux” package in Ubuntu:
  Invalid
Status in “openssh” package in Ubuntu:
  Confirmed

Bug description:
  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.
