How to pass SSH options such as StrictHostKeyChecking?

[Mehdi Sadeghi]

Hi there,


I am using saga-python in background along with userpass ssh context. Therefore I need to directly login to remote host. First time that one does ssh to a host there is a question whether we trust the remote host or not. There is a flag called "StrictHostKeyChecking=no "to change this behavior.

I have troubles passing this flag to saga job service. Can somebody please help me with this issue?

Thanks, Mehdi

Hmm, I though we'd pass that flag by default already - let me check...

Ah, no -- but what we *do* check is if the remote side prompts for a
confirmation of the key, and we blindly send a 'yes' [1]. I assume
that does not work for you? In that case I would not mind setting the
flag by default instead...

Best, Andre.

Hi Andre,

I just checked with my laptop at home. As you said SAGA will add the host to my known hosts. But for any reason on my computer at work it was prompting for a password and I was getting an exception for that. I can provide you with more information if you need. BTW I have tried to add that key to ~/.ssh/config file to force ssh to skip that question.
