Subject: copying files to remote machine

Hey all,

I've got a little script that is attempting to copy images to a  
remote server.  The significant parts of the script were taken  
directly from recipe 14.11 in the ruby cookbook.

relevant sections:

# directly from cookbook recipe 14.11
def remote_copy(session, source_path, destination_path=nil)
   destination_path ||= source_path
   cmd = %{cat > "#{destination_path.gsub('"', '\"')}"}
   cat_process = session.process.open(cmd)

   cat_process.on_success do |p|
     p.write(open(source_path) { |f| f.read })
     p.close
     puts "Copied #{source_path} to #{destination_path}."
   end
end

# slightly modified from same recipe
Net::SSH.start 
('remote.server.com', :username=>'user', :password=>'pass') do |session|
   Film.find(:all).each do |film|
     if film.small_local_cover_image_exists?
       remote_copy(session, film.small_local_cover_path,
                                                 
film.small_remote_cover_path)
     end
   end
   session.loop
end

When I run it works for about the first 4 or 5 films then dies with  
this message:

/usr/lib/ruby/gems/1.8/gems/net-ssh-1.0.10/lib/net/ssh/transport/

Thanks in advance for any help!
