Re: [Fab-user] Logging out as a user

[Jeff Forcier]

Hi Erich,

Thanks, I had skimmed over the fact that *disconnecting* was the key,
and not making a new one. Sorry for that, Brett :)

The connections are simply Paramiko objects, and can be accessed in
fabric.state.connections (which is a dict whose keys are host
strings.) They can then be .close()'d as you might expect.

For example, see the tail end of Fabric's main execution loop:

    http://code.fabfile.org/repositories/entry/fabric/0.9/fabric/main.py#L439

This stuff isn't part of the API, so keep in mind that it may get
moved around; but it will get added to the API at a later date and at
that point it will be A) easier to use and B) stable.
