Net::SCP::Expect RSA Fingerprint Problem

anshumangoyal has asked for the wisdom of the Perl Monks concerning the following question:

I am facing issue with Net::SCP::Expect while performing SCP. It sometimes dies saying

The authenticity of host can't be established.
RSA Fingerprint is XXXX
Are you Sure Yes/No
[download]

I want to check how Net::SCP::Expect can perform no host checking and just do an SCP. Is there any way to do that?
