I would suggest looking into using keys instead of passwords, and leveraging
agent forwarding. That should get you around the entire problem.

Subject: Net::SSH expect like interface
Hi All,
I have been looking for expect like interface for Net::SSH lib,
but apparently there is none.
Net::SSH is working fine for me except one place I need to check
the scp command prompt and send the password. (Invoking scp on
the machine to which I have ssh'ed).
Can somebody on list, provide some guidelines as to how can this
be achieved.
- I tried sending the password blindly to the popen session once
i get on_success or on_stderr callback. However this seems to be
not working. The log says..

--------
What I think is that there are these extra keysequence that are being
passed to the sever.
Do I need to emulate any kind of terminal for this to work.
What will be the best approach to implement expect like interface to
Net::SSH if at all
I can't get this working with existing functinoality.
Any pointer will be greatly appreciated.
Thanks and Regards,
Manish
