Steps

As user root give the command:
apt-get install build-essentials
which will download and install several utilities. This is required to ensure that all pre-requisites for building and installation of CPAN modules are available.

Then give the command:
perl -MCPAN -e 'install Bundle::Expect'
which will build and install the Expect.pm Perl module along with all of its pre-requisites.

Then create a file: connect.pl
containing the following Perl code:

------------------------start code--------------------------
#! /usr/bin/perl
$| = 1;

use Expect;

$script = 'ssh -p 6174 rt01.demo@rt01.rtfxd.com';
$exp = new Expect;
$exp->spawn($script);

$password = "rtfxd";

#timeout
$t=5; #exit if there is no update in 5 seconds

$exp->expect($t,
     #response to query:
     [ 'Are you sure you want to continue connecting .*$' => sub {
         $exp->send("yes\r");
         exp_continue;
         }
     ],
     #response to password request:
     [ 'password: $' => sub {
         $exp->send("$password\r");
         exp_continue;
         }
     ],
     #acknowledge receipt of timestamp line starting with character '@'
     #this resets the timeout timer
     [ '^@.*' => sub {
         exp_continue;
         }
     ]
)
------------------------end code----------------------------
