Re: Two factor authentication?

The Connection.__init__() constructor sets self.client to an instance of the paramiko SSHClient class, so you can alter it as needed after init. Connections are not actually established until Connection.open() is called, which happens automatically when using Connection.run or other functions that

Hi Mich, The connection object (you're using ctx in your examples) has a .local method that is just a pass-through to invoke.run. It's documented on the connection object's page: http://docs.fabfile.org/en/2.4/api/connection.html?highlight=local#fabric.connection.Connection.local On Mon, Apr 1,

You need to have your worker function catch any exceptions ( https://github.com/fabric/fabric/blob/1.14/fabric/exceptions.py) and evaluate success/failure, then return a value useful to you in determining if your task was successful. Returning "None" for failure modes is something I've done
