I have defined def check_kernel_version(c) in the fabile.py but when i
$fab2 check_kernel_version
No idea what 'check_kernel_version' is!
$fab2 check-kernel-version

I am not sure how does it work?
For $ fab2 check-os-version
I am encountering socket.gaierror: [Errno 8] nodename nor servname provided, or not known
Please guide. Thanks in advance.
