While using Net::FTP inside a firewall. Make sure to use the passive option else the get data functions might freeze because the firewall does not allow incoming connections.

Here is how the ftp code will look

  ftp = Net::FTP.new('ftp.netlab.co.jp')
  ftp.login
  ftp.passive = true
  files = ftp.chdir('pub/lang/ruby/contrib')
  files = ftp.list('n*')
  ftp.getbinaryfile('nif.rb-0.91.gz', 'nif.gz', 1024)
  ftp.close
