That won't work, ever. I wasn't kidding when I said scp, ssh, su, sudo, and most other sane authentication systems are explicitly designed to prevent this -- it's easy for a C program to tell a pipe or file apart from a real terminal, and easier still for a program to just ignore them and talk to the raw terminal itself, /dev/tty, neatly bypassing any redirection. This is because 'interactive password authentication' means 'password typed by a human authentication'.

You'd need to resort to third-party brute-forcing utilities to forcefeed it a plaintext password from file. Fortunately, there's better ways built into ssh as a standard feature: keys.

network.conf

NETSCRIPT-2.2.conf(5)                                           File Formats Manual                                          NETSCRIPT-2.2.conf(5)

NAME

       /etc/netscript/network.conf - interface, firewalling, and QoS configuration file.

       /etc/netscript/if.conf - interface setup shell script file

       /etc/netscript/qos.conf - QoS setup shell script file

       /etc/netscript/ipfilter.conf - IP chains filtering shell script file

       /etc/netscript/srvfilter.conf - server IP filter shell script file

DESCRIPTION

       This manpage is a place holder until something better is written when the netscript itself has stopped changing rapidly.

       Please  see  the README file in the /etc/netscript directory, and READ the configuration files if you need to change them.  Apart from net-
       work.conf, all of them contain sh (1) shell script functions which are there so that various things can be altered  or  hooked  in  at  the
       right place. Network.conf contains the full network setup details, including special interface setup for the likes of ciped/pppd/wanconfig,
       and is fully commented with examples given.

UPGRADE PATH FROM KERNEL 2.2.X
       The firewall/IP filtering stuff in ipfilter.conf is the part that changed radically with the move to iptables and a far better way of  set-
       ting  up  the  IP filtering rules, however the QoS and interface startup/shutdown in if.conf have changed but are backwards compatible with
       the old 2.2.x ipchains version of netscript for the interface address configuration settings.  You will have to set up the filtering  again
       to use iptables by directly using the iptables commands.

       Also,  the  kernel  2.2.x version scripts are set up so that iptables is only run on a 2.4.x kernel, otherwise IP forwarding is disabled if
       beforehand you set IPFWDING_KERNEL to FILTER_ON in network.conf.

       This means that when you upgrade a box to a 2.4.x router kernel, you should then be able to reboot it and log  into  remotely  and  upgrade
       netscript  to  the version that will support 2.4.x.  In this situation, if you have set old IPFWDING_KERNEL setting to FILTER_ON beforehand
       in network.conf, all IP forwarding through the box will also be disabled.  This means that you can safely remotely upgrade a firewall.
