[Fab-user] ssh and known_hosts

[Tim Arnold]

I am getting started with fabric and trying to connect to any machine in 
my known hosts file. I want fabric to figure out that it doesn't need me 
to enter my password. 

My fabfile.py: 

from fabric.api import run, env 
env.disable_known_hosts=False 

def lsfiles(): 
     run('ls -l ~/') 

My console result: 

  fab lsfiles 
No hosts found. Please specify (single) host string for connection: 
localhost 

[localhost] run: ls -l ~/ 
[localhost] Passphrase for private key: 

... file listing follows ... 

How can I get fabric to use my .ssh/known_hosts file?
