Re: [Fab-user] Creating a tunnel with Fabric

[Christian Vest Hansen]

The use of a context manager do indeed strike me as elegant, and a
quick googling suggests that paramiko is capable of port forwarding.

Unfortunately, I can't comment on whether the fabric context managers
in their current incarnation are powerful enough to do this. Jeff
should know, but he is currently in the process of recovering from an
operation, I hear.
