I'm running it from Ubuntu (Hardy 8.04) to a remove machine also  
running Ubuntu (Hardy 8.04).

I installed paramkio via apt-get on Ubuntu so its 1.6.4-1.1
And using Fabric v. 0.0.9

Here's some sample fab code I used:

def test_rm1():
    set(fab_hosts = ['somehost.com'],)
    sudo('rm /foo.txt')

def test_rm2():
    set(fab_hosts = ['somehost.com'],)
    sudo('rm -fr foodir')

Here's the associated output:

Running test_rm1...
Logging into the following hosts as foobar:
    somehost.com
Password for address@hidden:
[somehost.com] sudo: rm /foo.txt
Error: The sudo operation failed on somehost.com:
    Socket is closed

Running test_rm2...
Logging into the following hosts as foobar:
    somehost.com
Password for address@hidden:
[somehost.com] sudo: rm -fr foo
Error: The sudo operation failed on somehost.com:
    Socket is closed

Thanks again for the help,
