title: How to build a rubygems mirror server?
body: <p>My workplace has banned us  from internet access so we can't connect to rubygems.org to install gems remotely.</p>
  
  <p>I can access rubygems.org at home. Is there a simple way to enable me download and update the  gems we need at home ,then sync them(by a portable hard disk or somthing) to a local gems mirror server at my  workplace so that other colleagues can
  install gems from that mirror server?</p>
