[Fab-user] SSHException with Ubuntu 9.04

[Ted Carroll]

I'm trying out fabric for the first time so this is probably a silly  
config problem on my part, but I'm running ubuntu 9.04 in a vmware vm  
and having a lot of problems getting SSHExceptions.  Here's a fabfile  
that reproduces the problem:

from fabric.api import *

def production():
    env.hosts = ['192.168.1.228']
    env.user = 'deployment'
    env.password = 'password'

def test_sudo():
    require('hosts', provided_by=[production])
    put('apache-website-config', 'apache-website-config')
    sudo('rm -f apache-website-config')
    sudo('rm -f bad_file_name2')

The output is:

/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site- 
packages/Crypto/Hash/SHA.py:6: DeprecationWarning: the sha module is  
deprecated; use the hashlib module instead

It seams to be intermittent -- occasionally it will work but mostly it  
fails.

Any ideas?

Thanks,
