Fabric over reverse SSH tunnel

问题:

Is there a trick to running Fabric over a reverse SSH tunnel? An interactive ssh connects fine back over the turnnel, but running fab, I just get asked for my password repeatedly.

Here is a snippet with a solution

Here's a solution that doesn't involve writing any extra Python code:

If you set up your SSH configuration to tunnel over a SOCKS proxy, you can tell Fabric to use the SSH configuration. It's sweet.

Example $HOME/.ssh/config file:

Host bastion
HostName bastion.yourdomain.com
DynamicForward 0.0.0.0:1080
ServerAliveInterval 120
ServerAliveCountMax 30

Host hostbehindthebastion.yourdomain.com
ProxyCommand /usr/bin/nc -x 127.0.0.1:1080 %h %p

Now tell Fabric to use the configuration:

env.use_ssh_config = True
env.hosts = [
    "[e-mail]",
]

Now ssh bastion in one window, then run fab from another window.

See the official Fabric documentation for more information.

NB. You will have to have nc (netcat) installed on your machine to use this solution.
