我的情景：
Local host -> Gateway -> Remote host
我已经尝试过网关选项：
fab -g user@host task
但它不起作用。有没有人有说明和提示？
这是详细信息：
xdays@localhost:~/Public/fabric$ fab hello
[vps.xdays.info] Executing task 'hello'
[vps.xdays.info] run: echo Hello!
[vps.xdays.info] out: Hello!
[vps.xdays.info] out:
Done.
Disconnecting from vps.xdays.info... done.
xdays@localhost:~/Public/fabric$ vim fabfile.py
xdays@localhost:~/Public/fabric$ fab hello
[vps.xdays.info] Executing task 'hello'
[vps.xdays.info] run: echo Hello!
[vps.xdays.info] Login password for 'root':
[vps.xdays.info] Login password for 'root':
Stopped.
xdays@localhost:~/Public/fabric$ cat fabfile.py
from fabric.api import local, run, env
env.gateway = 'xdays@localhost'
env.user = 'root'
env.hosts = ['vps.xdays.info']
env.password = 'password'
def hello(name='world'):
'''just hello'''
run('echo Hello!')
