Re: [Fab-user] Internal SSH'ing

[BRAGA, Bruno]

Thanks Amit,

I believe it partially solves it... but I have a bunch of stuff to do locally, so I'd still need to break them into a 2-step scripting, where I can execute everything then trigger the SSH into the private network, which then would execute the rest in there...

I had this idea in mind. I first login to your private network -- your
entry point and execute a fabfile from there. I tried something like
this and it seems to work. Please see [1].

As you can see, I first execute the task in fabfile.py on  '10.0.0.9',
(say, the private network entry point). This fab file copies the
fabfile which contains tasks that I want to execute on a bunch of
other nodes, say 10.0.0.27. (just one).

Does this work for you?
