SSH Module Proposal
As an initial platform to enable data plane discovery, implement an SSH module using paramiko by extending its SSHClient class.
Desired Interface
>>> from satori.common.ssh import SSH
>>> client = SSH(host="123.456.789.11", host_password="pa$$word", host_username="Tobias")
>>> output = client.remote_execute("sudo echo hello", with_exit_code=True)
>>> print output
{'stdout': 'hello', 'stderr': '', 'exit_code': 0}
Requirements
- Manage authentication mechanisms, retry authenticating, and prefer SSH keys.
- Mange connecting and disconnecting when
remote_execute()is called. (Lazy load the auth object) - Attempt to handle password prompts for non-passwordless sudoers
- Attempt to handle requirements for pty/tty by retrying with a pty channel [1] if the system responds with "sudo requires a tty" or similar
- Support ssh proxy connections [2], and create an implementation that provides the same behavior whether connecting through a proxy or connecting to the remote host directly.
- Implement an instance property,
platform_info, that will return the remote host's platform info using (python >=2.4)'s platform module- architecture, distro, version
- e.g. Ubuntu 12.04 x86_64 would return
-
{'arch': 'x86_64', 'dist': 'ubuntu', 'version': '12.04'}

- ↑ 1.0 1.1 paramiko.channel.Channel.get_pty See get_pty().
- ↑ 2.0 2.1 paramiko.client.SSHClient.connect See sock keyword argument.
