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:

Thanks in advance for any help!
