Get on Athena

MIT manages 2 networked filesystems: AFS and DFS. Files stored on AFS are accessible from any computer anywhere in the world (provided one has the proper credentials). Files stored on DFS are available from public cluster WinAthena computers ONLY. AFS is clearly the more flexible. MIT's AFS system (or 'cell') is called 'Athena'.

There are 2 ways of accessing files on Athena: Secure FTP and OpenAFS. Though cumbersome, secure FTP is the surest way of connecting. OpenAFS provides seamless AFS integration with the Finder (Macintosh) and Explorer (Windows). OpenAFS can be a bit touchy at times. We recommend you install both.
