No one? I've been trying to work this one out for over a week now, and no
matter how I try this doesn't seem to work at all. Any help would be
appreciated. If it's a bug I'd also like to know to stop banging my head
with the settings. Even using fab tool and a fabfile.py like this:
$ cat fabfile.py
from fabric.api import run
def host_type():
run('uname -a')
$ fab -f fabfile.py -H host.org:4242 -k host_type --user adrian --gateway
root@192.168.242.153:22
[host.org:4242] Executing task 'host_type'
[host.org:4242] run: uname -a
[host.org:4242] Login password for 'adrian':
[host.org:4242] Login password for 'adrian':
It stalls there forever. Then I Ctrl-C and get this:
^C
Stopped.
Disconnecting from root@192.168.242.153... done.
And stalls again.Then I Ctrl-C on that one too and get this:
^CError in atexit._run_exitfuncs:

Thanks!
