Subject: Unable to change password using Net::SSH

Running on WinXP, ssh to Solaris.  Tried using the shell as well as
popen3 channel method but doesn't work... just sits there spinning..
Let me know what I'm doing wrong, if it's even allowed

<--popen3 channel method-->
require 'net/ssh'

session = Net::SSH.start( 'myserver.com',
                  'user_id',
                  'old_password',
                  :auth_methods => %w(password keyboard-interactive) )

session.process.popen3( "passwd" ) do |input, output, error|
	[ "old_password", "new_password", "new_password" ].each do |passwords|
		input.puts passwords
		puts output.read
	end
end

session.close

<--shell method-->
require 'net/ssh'

session = Net::SSH.start( 'myserver.com',
                  'user_id',
                  'old_password',
                  :auth_methods => %w(password keyboard-interactive) )

shell = session.shell.sync

out = shell.pwd
p "Working Dir==>>" << out.stdout

out = shell.send_command( "passwd", <<CMD)
old_password
new_password
new_password
CMD

p out.stdout

shell.exit
session.close
=============

If this is not allowed, please suggest other options to change
passwords on unix servers in programmatic fashion.

Thanks ...
