in thread Net::SSH::Perl returns error on pty allocation

Is there an option to send commands and collect output when using $ssh->shell interactive mode?

I think this is the only way I'll success since customer node is not a standard Linux box

Anyway, this is the output when I run the code above:

    Try adding set_interactive to the constructor.

      I tried most of options provided by Net::SSH::Perl module but failed to get good results

      On the other hand Net::SSH::Expect module worked perfect for me

      Thank you all
