[Fab-user] linux ssh: Remote Host Identification failed

[Prasant J]

Hi,

I'm making a python GUI program that uses fabric and performs
operations on the remote device. I'm new to python as well as fabric.
My python program is al most complete.


My Query:
When the remote host identification has changed, fabric throws
Exception: NetworkError. Is there a way by which I can ask fabric to
bypass remote host identification check?

Any inputs will be of help to me.


Regards, Pj

Hi,

you can try to set disable_known_hosts to True. You can set it in the CLI
or using the env configuration dictionary.

fab --disable-known-hosts your-task -H your-host

You can check the docs here [
http://docs.fabfile.org/en/1.12/usage/fab.html#cmdoption-D]

Thanks Carlos for the response!


I'm using fabric as library in my program.
I'm setting up environment first (env.user, env.password) and then
using run() to execute the command.

How can I set "disable-known-hosts" in this case? (I know how to use
from command line)

Could you please point me to an example or provide some inputs so that
I can use this feature?

Hi,

if you’re setting user and password, this should be super easy

from fabric.api import env

env.disable_known_hosts = True

If you are using fabric as a library, would be a good idea to have a setup
function or module, where you can set all relevant settings together.
